Different Ship, Same Virus : Taiwan Navy Battles COVID-19

The COVID-19 pandemic which began in Wuhan City, China late last year has now spread to almost the entire world ( 185 countries ) with a total of more than 2.92 million infected and 200000 deaths. Due to its mode of transmission through respiratory droplets and direct contact between individuals, anywhere with a high population density and a high rate of social interaction will be at risk of an outbreak. We have seen how cruise ships can become epicenters of the COVID-19 disease, with the virus infecting passengers and crew alike as they are all trapped onboard with nowhere to go or hide, and how it can spread beyond the ship after docking. Military vessels are not much different from their civilian counterparts with large numbers of sailors living and working together in confined spaces and can therefore be assumed to have a similar risk profile. Recent COVID-19 outbreaks on the USS Theodore Roosevelt ( CVN-71 ) and the French Navy's FS Charles de Gaulle ( R91 ), both nuclear powered aircraft carriers, have proven that even the most advanced navies are incapable of completely shielding themselves from the virus.

Last week, another ship had the unenviable honour of joining the list - the ROCS Pan Shih ( AOE-532 ) fast combat support ship of the Taiwan Navy. The outbreak occurred during a midshipman training cum friendship deployment to the western Pacific nation of Palau ( 帛琉 Bo Liu in Chinese ), ironically one of the last few places on Earth with still no reported COVID cases. At the time of writing, there are 31 confirmed cases of COVID-19 infection all of whom have embarked on the Pan Shih supply ship. Procedural lapses during and after the deployment meant that 744 naval personnel were granted home leave and had dispersed to 90 different sites in 10 counties before they were recalled for testing. The Taiwanese government is now in a race against time in contact tracing and is even contemplating the unthinkable - a lockdown. We review how the recent events unfolded and try to understand that apart from the immediate risk of triggering a nationwide epidemic, what else could be at stake for the Navy and Taiwan from the fallout of this shipboard health crisis.



Taiwan's Dunmu Friendship Deployments



Taiwan is officially known as the Republic of China ( 中華民國 Zhonghua Minguo ). It is an island separated from mainland China by the Taiwan Strait ( Formosa Strait ). It considers itself a country and is ruled by a democratically elected government. The Chinese however considers Taiwan a renegade province and has always claimed the island as its own sovereign territory. China has actively opposed the declaration of independence by Taiwan and had prevented Taiwanese membership from many international organisations such as the United Nations and the World Health Organisation. Taiwan on the other hand tries to forge as many alliances as possible, usually through direct financial and humanitarian aid incentives, but has so far found success with only an ever dwindling handful of small and poor nations in Africa, the Caribbean and the southern Pacific. The Republic of Palau is one such example.

In support of its international outreach program, the Republic of China Navy ( ROCN ) has been conducting friendship missions to its allies to strengthen military and diplomatic ties since 1953. Known as the Dunmu Long Distance Sea Training Detachment ( 敦睦遠航訓練支隊 ), it is mainly a naval officer cadet or midshipmen sea training deployment with a secondary objective of diplomacy and cultural exchange. It became a regular annual affair since 1965, with the fleet initially visiting places like Singapore, Indonesia, Philippines, but increasingly the south Pacific localities including the Solomon Islands, Marshall Islands, Tuvalu, Nauru, Kiribati, Fiji and the central American region - Honduras, Dominica, Belize, Panama, St Vincent, Guatemala, Grenada, Haiti and Salvador.

Apparently, there is a great amount of significance attached to these Dunmu missions and only the best of the best among the naval fleet commanders are selected to lead the flotilla every year. This is according to Taiwan's retired Chief-of-Navy Admiral Ye Chang-Tong ( 葉昌桐 ). Upon the successful conclusion of the mission, the award of medals and commendations are the norm.


The Friendship Flotilla



The Dunmu 2020 fleet consisted of three ships, the fast combat support ship ROCS Pan Shih 磐石艦 AOE-532 ), the stealth frigate ROCS Kang Ding ( 康定艦 FFG-1202 ) and the guided missile patrol frigate ROCS Yueh Fei 岳飛艦 PFG-1106 ). A total of 744 naval personnel embarked for the deployment out of which perhaps slightly more than 200 must have been comprised of the midshipmen and their instructors from the R.O.C. Naval Academy, undergraduates from the Political Warfare Cadres Academy Fu Hsing Kang College, a detachment of the honor guards, the ROCN military band and the marine corps. The task group commander is Rear Admiral Chen Tao-Hui ( 陈道輝 ), a naval veteran of 30 years.

The Pan Shih is the ROCN's largest ship by tonnage with a full load displacement of 21194 tons. It is very new, having been in commission only since 2015. It is a logistic ship designed to conduct replenishment at sea with 2 vessels at the same time. It carries fuel, ammunition, dry stores and refrigerated stores. Built with Humanitarian Assistance and Disaster Relief ( HADR ) missions in mind, it has hangars that can accommodate up to 3 medium helicopters and even has a medical and dental center complete with an operating theatre and 3 wards with a total capacity of 15 beds. It has blood storage facilities, X-ray and ultrasound, a laboratory and even negative pressure isolation rooms for infectious diseases. It has a complement of 165 but for the Dunmu mission a total of 377 personnel embarked. Since 2016, the Pan Shih has been the designated flagship for all the Dunmu missions.

The Kang Ding is a modified La Fayette-class stealth frigate built by the French contractor Thales / DCNS in 1992. The procurement of the Kang Ding frigates was marred by a huge corruption scandal involving commissions and kickbacks of some 500 million dollars and even the murder of a naval captain Yin Qing-Feng in 1993. 13 other Taiwanese and French nationals involved in the scandal subsequently died under mysterious circumstances ... the list can be found at the bottom of the article here. Despite its inauspicious beginnings, the somewhat ageing stealth frigate is still a potent surface combatant though, and the ROCN plans to upgrade its Sea Chaparral missiles with the naval version of the Tien Chien II AAM ( TC-2N ). It displaces 3200 tons and has a complement of 176.

The Yueh Fei is a Cheng Kung-class patrol frigate whose design was based on the FFG-7 Oliver Hazard Perry-class frigates of the US Navy. It bears the characteristic profile of the FFG-7 frigate complete with the forward Mk 13 missile launcher which when viewed at certain angles would seem like the ship is giving the middle finger sign. Like the Kang Ding frigates, the Yueh Fei is armed with both the indigenously developed Hsiung Feng II and III anti-ship missiles. With a full load displacement of 4169 tons, it can accommodate up to 2 anti-submarine helicopters and has a complement of 235.

Dunmu 2020


The Dunmu deployment typically starts in late February or early March with an island wide stopover at several large cities or ports in Taiwan over the span of two to three weeks. This is the local training phase (  国内航训 ). Kaohsiung, Makung, Su'ao, Hualien, Taichung, Keelung and Tainan are usually included. At each port, the ROCN will have an open house event lasting for two days where the public will be welcomed to visit the ships. Part of the aim is to attract young people to join the navy as career soldiers.

This year, the detachment officially formed on 20th Feb 2020 but most likely due to the movement restrictions from the authorities there has been no mention about ship open house events. The flotilla departed Kaohsiung City's Zuoying Naval Base on 5th Mar bound for the Republic of Palau in the southern Pacific. It would have been the 15th visit to Palau by the Dunmu deployment since 2001.

The Dunmu Detachment arrived at Palau on 12th Mar but due to Palau's port regulations only the stealth frigate Kang Ding docked while the other two ships remained at anchor off-shore. The usual welcoming ceremony and diplomatic exchanges took place and there were several performances that took place including the martial arts demonstration by the marine corps and the marching band performance by the Naval Academy. A friendly game of softball took place at the Asahi Field after which the detachment commander Adm. Chen donated a set of softball equipment to the Palau Softball Team. While at the pier and just before the departure on 15th Mar, the Kang Ding conducted a joint flag hoisting ceremony where both the Taiwan * and the Palau flag were raised simultaneously. Staff from the R.O.C. Embassy in Palau which included the Ambassador Wallace Chow and some local dignitaries from Palau were invited onboard to witness and participate in the ceremony.

* The flag of Taiwan is also known as the Blue Sky, White Sun, and Wholly Red Earth flag ( 青天白日满地红 Qing Tian Bai Ri Man Di Hong ). The significance of each component here.

Due to the COVID-19 pandemic, the detachment did not have any other port visits apart from Palau which is most unusual. It would have otherwise visited several countries in a normal year. Palau could have been chosen as the sole Dunmu destination because it was free from COVID-19 when the fleet departed Taiwan, just as it is still officially free from the virus today. The flotilla then spent the next 25 days at sea until its arrival back at Zuoying Naval Base on 9th Apr, without any interaction with foreign navies or any port visits, as claimed officially. Not including the local training phase before 5th Mar and the 6 days of quarantine after arrival on 9th Apr, Dunmu 2020 spent 36 days at sea, the shortest on record. In contrast the Dunmu 1981 mission to South Africa had spanned a total of 82 days at sea.

Since the trip to Palau only took 7 days but the return journey had taken 25 days, there was a lot of speculation as to where the flotilla went and what it did during the 18 "unaccountable days". Conspiracy theories abound as to whether the fleet had visited Guam where the USS Theodore Roosevelt lay stricken by the coronavirus or whether the fleet had participated in training exercises with the USN* which was conducting live firing operations in the Philippine Sea around that time and then somehow got infected. On 24th Apr under public scrutiny, the Ministry of Defense through spokes person Brigadier Shi Shun-Wen finally revealed the route map of the Dunmu 2020 which showed that after departing Palau the fleet sailed south west passing south of Mindanao through the Celebes Sea, passing through the Makassar Strait between Kalimantan and Sulawesi, through the Java Sea towards Singapore ( closest approach on 27th Mar ) and then turned northeast through the South China Sea past the Taiwan administered Taiping Island which is the largest of the naturally occurring Spratly Islands, and then the Taiwan controlled Pratas Islands ( Dongsha Islands ) before arriving home in Zuoying Naval Base.

The original plan was for the fleet to sail north through the Strait of Malacca ( dotted red lines ) to demonstrate the long distance and endurance capabilities of the fleet with a stop over in Singapore for replenishment. However the deteriorating COVID-19 situation in Singapore during the second half of March with double digit growth in daily new infections made the naval command change its mind.

The revelation of the flotilla's navigation route still did not shed any light on whether the navy had undertaken any special missions on the return leg. The Defense Minister denied any tasking of covert missions but President Tsai seemed to suggest that there were some special missions involved but she was not at liberty of disclosure, adding that the fleet did not go anywhere else other than Palau. My suspicion is the resupply of Taiping Island and Pratas Island by the Pan Shih logistic ship and perhaps some electronic or signal intelligence gathering in the troubled South China Sea.

The returning sailors were greeted by the President of Taiwan Tsai Ing Wen herself at the pier though due to the fear of COVID-19 the president merely waved from ashore and did not board any of the ships for an inspection.

The sailors were then quarantined for 6 days onboard their respective vessels before being granted home leave and dispersed from the naval base on 15th Apr. This was in accordance with Taiwan Centers for Disease Control ( CDC ) guidelines which required 30 days of quarantine from that date of departure from the last port of call. The Dunmu sailors would have fulfilled this requirement on 15th Apr if they had left Palau on 15th Mar and did not make any landfall after that.

The 6 days of quarantine were uneventful except that the two frigates Kang Ding and Yueh Fei were scrambled on 12 Apr to intercept the Chinese Liao Ning aircraft carrier group which was spotted by the Japanese crossing the Miyako Strait and held drills near Taiwan. They returned on 13 April. And so the Dunmu 2020 was supposed to have concluded and nobody knew at that time what was about to happen.


Taiwan-Palau Pandemic Prevention Cooperation Project



It is worth mentioning that on 2nd Apr just two weeks after the Dunmu visit, a special chartered flight from Taiwan arrived at Palau under the auspice of the Taiwan-Palau Pandemic Prevention Cooperation Project delivering a RT PCR machine, a centrifuge machine, an automated extraction machine, 1000 test kits and 2 infrared thermometers. Two Taiwanese medical experts from Shin-Kong Hospital also arrived to help with the installation of the equipment and to provide the necessary training to the Palauans. The reverse transcription - polymerase chain reaction ( RT-PCR ) method through a deep nasal or throat swab is currently the gold standard in diagnosing an acute COVID-19 infection. Those rapid serology test kits that involve blood testing for coronavirus antibodies ( IgM, IgG or both ) can only indicate past infection and are only useful for epidemiological studies and not for diagnosis. Many rapid test kit manufacturers vastly exaggerate the accuracy of their products. It is not uncommon to have claims of 90% sensitivity on Day 14 of infection but in practice only found to achieved 30% sensitivity.

The First Signs of Trouble



A trainee embarked on the Pan Shih was unwell since 12th Apr with headache and anosmia ( loss of sense of smell ) as the main symptoms. He sought treatment immediately after disembarking the ship and reaching home on 15th Apr. He had a repeat consultation on 17th Apr and subsequently tested positive for COVID-19 on 18th Apr and became Taiwan's Case 396. His bunkmate was similarly unwell since early April with sore throat, running nose, cough, headache and anosmia. He sought treatment on 17th April and was confirmed to be infected the next day, becoming Case 397. Another room mate had anosmia since 13th April and sought treatment on 17th April. He was tested positive becoming case 398.

It is notable that all 3 cases were trainees embarked on the Pan Shih sharing the same room. They had symptoms that can be suggestive of COVID-19 infection for several days prior to disembarkation but the commanders were not vigilant enough to take any preventive measures.


More Trouble



On 18th Apr with 3 confirmed cases from the ship, the navy hastily conducted an emergency recall for its more than 700 personnel from the Dunmu mission with the objective of testing all of them. By the next day, 21 cases were detected bringing the total number of infected sailors to 24. All were from the Pan Shih, the majority being trainees. 3 more new cases emerged the next day and the subsequent 4 days brought 4 more cases each, which made the latest tally 31 infected.

At the time of the recall, the Dunmu sailors had dispersed to more than 90 different cities and towns spreading over 10 counties and had come into contact with an unimaginable number of people. At the time of writing Taiwan CDC determined through contact tracing that there were 1843 at risk individuals of which 530 were advised home quarantine and 1313 were on self-monitoring.

To complicate matters, of the 19 assembly points for the emergency recall selected by the navy, 10 were various elementary and high schools all over Taiwan. The navy did so without first informing or consulting the schools, the Ministry of Education or the Mayors, thereby potentially placing the health of the students and teaching staff and the public at risk. The most contentious incident occurred at the Taichung Municipal First Senior High School where the military quarantine vehicle actually entered the school compound and cause alarm among the students, teachers and the large number of the members of the public in the vicinity of the school. It necessitated deep cleaning at the affected schools afterwards and generated a lot of unhappiness from the education community and the municipal officials.

Palau : Still No COVID-19?

 



The news of a COVID-19 outbreak on the ROCS Pan Shih understandably caused panic in Palau. In response to speculation that the Dunmu personnel could have contracted the coronavirus from Palau, the Taiwanese embassy staff in Palau as well as the locals who had visited the Taiwanese ship or had contact with the ship crew were subjected to COVID tests from 18 April onwards but none had turned out positive. So the origin of Pan Shih's outbreak seems less likely to have come from Palau especially when the first 3 cases all became symptomatic only after early April, more than 2 weeks after the flotilla departed Palau. We know that the incubation period of COVID-19 can be anywhere between 2 to 14 days with an average of about 4 or 5 days. However, subsequent serology tests on ship crew would have added doubt to this trend of thought.

It is important to understand that a negative COVID-19 swab test does not exclude an infection as all medical tests including the RT-PCR test have a small inherent false negative ( as well as false positive ) rate. Therefore no single test method can claim to be foolproof or have 100% sensitivity. Further more, the swabbing procedure itself is operator dependent and if the sampling is not done properly, for example the nasal swab not inserted deep enough or at the right spot means that the accuracy of the test can be affected. Here's a good video on how a proper nasal swabbing is done courtesy of the New England Journal of Medicine.

Another factor to consider is the proficiency level of the lab technicians doing the PCR and the bio-protective capabilities of the laboratory. PCR tests are complicated to perform and requires technicians with high level of expertise. Palau needed Taiwan's assistance for COVID-19 diagnosis as recent as Mar 2020 when it had to test a suspect case which fortunately turned out to be negative. The RT-PCR machine was donated only on 2nd Apr and we do not know how well trained the Palauan technicians are in just a matter of days. Once taken by the medical team of doctors or nurses, the swabs need to be processed by the lab which, according to US CDC recommendation, should be a BSL-2 ( Bio-Safety Level 2 ) lab with unidirectional airflow and adopting BSL-3 precaution. How much of these highly technical specifications can be met in a far flung locality like Palau is way beyond my imagination.

So is Palau really the last place on Earth that is COVID-19 free? A tropical paradise it definitely is but I would not be so certain about its COVID free status. After all, with a testing capacity that is said to be between 30 to 60 a day, only a small fraction of its citizens had been tested. Palau has plans to test 500 people within the next 3 weeks.

Hunt For The Source




With the aim of uncovering the origins of the COVID-19 infection onboard the Pan Shih, the Taiwanese authorities began conducting serology test on the Dunmu participants. Unlike the diagnostic RT-PCR test, serology testing for antibodies against the SARS-CoV-2 virus which causes COVID-19 will reveal prior infection. Depending on type, these antibodies begin to appear in the body and reach detectable quantities from about day 5 of infection onwards and will remain in circulation for at least months to years after the infection. To their surprise, at least 30 sailors from Pan Shi actually had circulating antibodies against the COVID-19 virus which indicated that Case 396, 397 and 398 were NOT the first three cases from the ship. It tells us that the infection had probably been brewing onboard the Pan Shih for sometime and it had spread among the ship crew without the knowledge of the medical team. The index case ( the first infected person ) can only be discovered through a thorough contact tracing effort with the help of the case notes of the ship's medical officer. Hopefully the doctor would have kept good and detail notes on the daily sick parade that was conducted onboard the ship.

So far the Defense Ministry had determined that 148 persons had reported sick a total of 226 times fleet-wide during the entire deployment. Of these, 10 had symptoms suggestive of upper respiratory tract infection ( cough, running nose and sore throat ) and 5 had fever. The medical officer did not believe these were anything more than a common cold or an influenza infection. Of these 5 febrile cases, only one was deemed serious enough by the detachment commander to be reported to the Naval Command. Serology tests would reveal that 3 of these 5 febrile cases tested positive for the antibodies but had negative PCR test, confirming that they had prior COVID-19 infection and had since recovered. They had fever on 21st, 23rd and 26th Mar respectively, well within 14 days of departing Palau.

It would seem to me that the medical team should have had demonstrated heighten vigilance against the possibility of COVID-19 infection given the rapidly deteriorating global situation in March and April.

The result of the serology surveillance, in combination with the knowledge gained from the USS Theodore Roosevelt COVID-19 epidemic that about half of those infected remained asymptomatic, can only mean that Palau can still be the source of infection. The only way Palau could have absolved itself was for the ROCN to prove that disease transmission occurred onboard ship BEFORE the fleet's arrival at Palau. The crucial evidence therefore lies in the ship's medical log.

Of course there is still a possibility that the naval personnel did not get infected in Palau but after Palau. A possible clue would be that all the infected were exclusively from the logistic ship but not the frigates. Depending on the type of special missions that the Dunmu ships carried out, it might have been possible for the Pan Shih crew to get infected should they have unloaded supplies at the two Taiwan administered islands in the South China Sea, Taiping and Pratas. No doubt both are very tiny atolls equipped with airstrips but we know that there are many things that cannot be brought in by air, like heavy equipment and building and construction materials. How about anti-ship missiles for coastal defense, anti-access / area denial??

Did the flotilla visit the islands? Did they dock? Did anyone come aboard or did the ship complement go ashore? COVID-19 infection would have been much more likely if they did any of the above.

Casualties



On 21 Apr the Minister for Defense Yen De-Fa, his Deputy Zhang Ze-Ping, the Inspector General and the Chief of the Political Warfare Bureau made a public apology for the Pan Shi coronavirus cluster during a press conference. Yen held himself accountable and said that together with Chief of Navy Liu Zhi-Ping, they were both willing to accept any punishment meted out by the president, including that of resignation. He also announced the removal of the two highest ranking officers directly involved with the Dunmu 2020 mission, detechment commander Rear Admiral Chen Tao-Hui and his direct superior, commander of the R.O.C. Naval Fleet Command Vice Admiral Kao Chia-Pin (高嘉濱) from their current commands while awaiting the conclusion of the ongoing investigations.

Drama at the Legislative Yuan



On 22 Apr with the Pan Shi COVID-19 cluster developing into the largest in Taiwan, the defense committee of Taiwan's Legislative Yuan invited the Defense Ministry to an inquiry to clarify matters. Opposition KMT lawmaker Lyu Yu-ling, member of the defense committee had originally wanted 3 people to testify through video-link since they were all still under quarantine - Detachment commander Chen, CO ROCS Pan Shih and the medical officer who had the rank of lieutenant. It appeared that Dunmu commander Rear Admiral Chen Tao-Hui was under direct orders to keep mum and was forbidden to testified through video link. The Defense Ministry then told the Legislative Yuan the three officers had already stated the day before that they did not wish to appear on video-link while they were serving quarantine. All three were also apparently not contactable through their phones. The committee deliberated for an hour and was about to give up when Adm Chen somehow managed to call-in at the inquiry and his testimony was broadcasted to the entire assembly through legislator Lyu Yu-ling. In it, he swore that he would never hide the truth and spoke emotionally about how he would rather die at sea or die onboard his ship rather than knowingly bring harm to the Taiwanese people whom he had pledged to protect in the first place. He said that he would have immediately terminated the mission had there been a known case of COVID-19 in his task group. He was asked about the number of febrile cases in the detachment and whether he reported them to the naval command. The reply was there were 5 cases but only one was serious enough that he reported to the naval command. He was also asked about who had given the order to disperse the ship company on 15th Apr after 6 days of quarantine to which he said he did not have the authority and was merely following orders. It was then that the phone was snatched from the legislator by the Chief of Naval Staff Ao Yi-Chi and immediately silenced causing many members of the public to wonder if the naval command or the ministry of defense had something to hide. It took another day before the Deputy Defense Minister Zhang Ze-Ping came up with the explanation that the phone was taken away because the ministry was concerned about the state of mind of Adm Chen after his emotional speech which was interspersed with choking episodes and that to allow him to continue would be inappropriate. The phone was removed after the consent of legislator Lyu Yu-ling was sort.

To make things even more muddled, Adm Chen subsequently publically retracted some of the statements he made over the telephone link saying that he did not have a clear state of mind after 3 sleepless nights and 5 days of quarantine and could have remembered some of the facts wrongly.

All these drama only make the Taiwanese politicians and the military look like fools and only serve to provide entertainment for their communist counterparts on the mainland.




Taiwan's COVID-19 Response : Poster Boy No More?



Like Singapore, Hong Kong, Vietnam and China, Taiwan experienced a severe SARS epidemic in 2003 and had learnt many valuable lessons in disease prevention and control. As a result, Taiwan activated its epidemic prevention measures very early during the COVID-19 outbreak on 31 Dec 2019 when it received news about 7 cases of atypical pneumonia * being isolated for treatment in China. This was even way before human-to-human transmission was confirmed possible by WHO, before the illness was identified as a coronavirus disease. Taiwan just assumed it can spread among humans since isolation was required, and acted on that assumption immediately, implementing inspection measures for inbound flights from Wuhan. By 26th Jan short term visits from Hubei Province were banned from entry and by 5th Feb all tourist from mainland China were banned.

It even regulated the prices of surgical masks and had a nationwide system of rationing such that all citizens have access to masks and could buy at least 2 masks per week at 50 cents each. The price of surgical mask in Taiwan has now dropped to 20 cents with the easing of initial shortages. It helps that Taiwan is one of the major mask producing countries outside of China. It also went on to ban all export ** of masks keeping everything produced for its own people. Taiwan never had to lockdown its cities unlike what many other countries are doing but yet managed to keep its COVID-19 count before the Pan Shih incident to "only" 395 cases and 6 deaths despite being located practically at China's doorstep. It is the poster boy for the global COVID-19 response and the envy of many countries.

After 3 days without new cases known locally as Jia Ling ( 加零 zero added )on 14, 16 and 17 Apr, the sudden appearance of 31 new confirmed cases from the navy to form Taiwan's biggest COVID-19 cluster within a short span of a few days had really shaken the Taiwanese society. It created fears that the epidemic might spin out of control necessitating lockdowns. Taiwan's Centers for Disease Control website now lists 429 confirmed cases and 6 deaths.

Contact tracing had revealed that upon disembarkation, some infected sailors had, unknowingly, visited motels, hotels, karaoke lounges and other commercial malls and entertainment sites as well as restaurants before they headed home. 13 out of the first 27 positive cases admitted to having intimate contact with their partners before they were diagnosed, and these figures maybe under represented as not every servicemen might be completely forthcoming with their movement history and contacts.

There is a probable chance that Taiwan's Covid-19 numbers might spike in the next few weeks due to the navy's lapse in shipboard infection control and it might then have to relinquish its " gold standard " status becoming a cautionary tale like Singapore.


* The Chinese frequently use the term " atypical pneumonia "  to mean SARS and the Taiwanese took no chances when that term appeared in the Chinese media. That the causative agent was subsequently identified as a coronavirus ( which the SARS and MERS viruses belonged to as well ) only affirmed their conviction.

** In Jan 2020 a Singapore State-owned defence company ST Engineering with mask making facility ( Air+ N95 series ) in Taiwan found itself unable to export masks to Singapore because of the ban. To get around the ban, the production lines were shut and the automated mask making equipment were shipped back to Singapore. The incident is causing ripples even till this month.

Possible Casualty : Indigenous Defense Submarine




One might wonder how the coronavirus outbreak on a navy ship could have affected an ongoing high priority national defense program. Taiwan has 4 diesel-electric attack submarines, two of which are more than 70 years old ( ex-USN Guppy II ), used for training only and may not even be sea-worthy. The other two Chien Lung-class ( improved Zwaardvis ) SSK were all commissioned more than 30 years ago and are in urgent need for replacement. Since no submarine exporting country is willing to endure the wrath of China by selling submarines to Taiwan and the US no longer build conventional submarines, the Taiwanese have no option but to consider the indigenous route.



IDS model. Wikipedia




Launched in 2016, the Indigenous Defense Submarine ( IDS 自製防禦潛艦 ) project to build 8 diesel-electric attack submarines for the ROCN is a high risk project and success is not guaranteed. It is the pet project of President Tsai Ing Wen. Even with the availability of funds, blue prints, engineering expertise and yard facilities, submarine construction is highly complicated. Nonetheless the IDS program seemed to have progressed well so far and the construction of the first prototype was supposed to start at the end of this year and was projected to be completed by 2025. It would then undergo 1 to 2 years of sea trails before entering service.

However, not everyone has faith in the IDS project and there are always political entities especially those from the opposition KMT party calling for the project to be terminated. Currently one of the main proponent and main driving force for the project from the navy's perspective would be Admiral Huang Shu-Kuang ( 黃曙光 ), the ex-Navy Chief who was promoted to position of Chief of the General Staff on 16 Jan 2020 after the unexpected passing of his predecessor Gen Shen Yi-Ming in a UH-60M crash.

Adm Huang of course would have realized that the IDS program is a long term project and will never see fruition within the tenure of his own military career. Born in 1957, Huang would have reached mandatory retirement age by next year. He would have to have a clear succession plan to ensure the IDS project has the best chance of success. With his background from the submarine forces, it is of no surprise that he favours Vice Admiral Kao Chia-Pin, another ex-sub skipper and his subordinate, to be his successor. The two had a long history of friendship and cooperation - in 2007 Huang was squadron commander and Kao the skipper of the submarine Hai Hu SS-794 that successfully sunk a target ship, the oiler AOG-515, with a heavy torpedo during the annual Han Kwang exercise.

Kao himself is a high flyer and was the detachment commander of the Dunmu 2018 mission. As a rear admiral he created a new record by being appointed the Inspector General of the Defense Ministry, a position normally reserved for two-star generals and above. All this with the recommendation of his mentor Adm Huang of course. Kao's next appointment would be the commander of Naval Fleet Command ( 海軍艦隊指揮部 ) and was in-line and groomed to eventually be the commanding general of the navy.

Unfortunately, barely 6 months into his job as commander of Naval Fleet Command, he was relieved of his duties because of the COVID-19 outbreak in the navy. This really disrupts Adm Huang's succession plans as there aren't many high ranking naval officers within the ROCN that are submarine qualified. Unless he is reinstated pending investigations, lack of a suitable naval chief who thoroughly understands submarine warfare to continue to push the Navy's agenda for new submarines may eventually doom the project.

To make matters worse, it was also Huang who appointed Chen Tao-Hui as this year's Dunmu commander. Although Chen was previously a frigate captain and not submarine qualified, he was nonetheless one of the up and coming young flag officers that Huang admired. So in one fell swoop, two of Adm Huang's and the ROCN's promising generals had been removed from duty.

As it takes more than 20 years to groom a naval officer to senior ranks of rear admiral and above, many, including the 90 year old ex-navy chief Ye Chang-Tong, are questioning the rationale of removing the 2 officers for some things that are beyond their control.



From Routine Mission To Public Relations Fiasco



The annual Dunmu Friendship Mission by the ROCN is of great significance to the Navy as well as the nation of Taiwan. First it provides sea training for the graduating class of midshipmen who are expected to put all they had learnt into practice. It's their rite of passage. For Taiwan, it is a chance to show its handful of allies its appreciation of their friendship and recognition of Taiwan. It had never been interrupted for more than 50 years but in hind sight perhaps this year's friendship mission should never have taken place because of the COVID-19 pandemic.

By early March, there was already mounting evidence of rampant COVID-19 infection onboard multiple cruise ships and the situation on land was no better. Although China had successful controlled the spread of the virus through a nationwide lockdown, other countries in Europe and American were seeing exponential increases in their infected citizens.

ROCN made the decision to carry on with the friendship mission after consulting the Taiwan CDC and then had the President approved the mission. The worldwide COVID-19 situation is changing so fast that even 3 days would seem like a lifetime. CDC would likely not be able to accurately predict what would have happened 2 months down the road and played only an advisory role in any case. Adm Kao should not have given the green light for the mission and place the health of more than 700 sailors at risk. ROCN should never have assumed any place was COVID-19 free, including far flung Palau, especially when no tests were conducted in those localities.

At Palau, photos on social media have shown that the officers and men interacted with the local people mostly without wearing masks and also failed to maintain any meaningful form of physical distancing. This lack of caution could have stemmed from the false assumption that Palau is COVID-19 free. Now I am not saying that Palau has COVID-19 but rather nobody can be sure Palau does not have COVID-19. It pays to be careful.

The management of the sick crew members during the sea deployment was also wanting. It is probably of no secret that in a conscription based military system like those of Singapore, Israel and Taiwan, the most junior medical officer would be tasked to follow a long sea voyage. These young doctors may be qualified but are likely to lack experience having just graduated from medical school for not more than a couple of years. Still, to have febrile cases onboard the ship dismissed as just another case of common cold or influenza infection during a COVID-19 pandemic is beyond my comprehension. Granted it is not possible to differentiate between common cold and COVID-19 infection base on symptoms and clinical examination and that it is not possible to perform the diagnostic PCR swab test onboard the naval vessel. But at least the medical officer could have a heightened sense of vigilance and these sailors with flu-like symptoms should have been isolated straight away in one of the Pan Shi's negative pressure isolation rooms!


Failure of reporting most of these fever cases to command HQ also defies logic but perhaps the detachment commander had other considerations and chose not to report. He might be concerned that the Friendship Mission could be prematurely terminated should there be too many sailors coming down with fever and that could ultimately affect his performance appraisals and future promotion. In other less trying times, this would never be a problem as ships are rarely ever recalled for minor illnesses occurring onboard.

From past experience, during a deployment, the ship crew will hardly report sick once the ship is underway. They are young and generally healthy to start off with. Even when down with a minor illness, most would just self medicate rather than report sick. They will just continue with their usual watch duties as long as they are not too ill. On arrival at a port of call, nobody would report sick because everyone wants shore leave. The busiest time for the ship medic would be after the port visit when crew members would stumble in for treatment of traveler's diarrhea, minor wounds from falls and fights and sometimes sexually transmitted diseases. The last day of the deployment will also miraculously have nobody reporting sick as everyone wants home leave!

Now I believe it should be in every ship's Routine Orders that everyone should be checking their temperatures at least twice a day and anyone who is unwell or having a fever should report sick without delay. The medic should assume that fever + acute respiratory infection = COVID-19 and isolate until proven otherwise. Even more worrisome are those infected that showed no symptoms as the USS Theodore Roosevelt experience have taught us - half of those infected did not display any signs or symptoms! So the best course of action now for the navy is not to deploy the ships at sea unless it involves a mission that is critical to the survival of the nation. Training missions and diplomatic missions like the Dunmu deployment can be postponed until the pandemic is under control. The graduating midshipmen may miss their sea training but let them graduate anyway. They can join their juniors in the following year's Friendship Mission as ensigns.

The handling of the recall also showed that the navy was completely unprepared for such an event. Some kind of recall plans should have been made even before the ship crew dispersed. Randomly choosing schools as assembly points puts the students and public at risk of infection. Many would have taken public transport to the assembly points and whoever had contact with them could be endangered as well. It does not make sense for a mass recall to have happened this way. Remember that by 18 Apr which is 3 days after dispersal, the ship crew are now scattered all over Taiwan with one even reaching Jinmen Island. Instead, the ship crew should have been told to report to the nearest government test centre for COVID-19 tests immediately. Better still, all returning sailors should have been tested for COVID-19 before being granted home leave just like what Singapore and China have been doing for some weeks - testing ALL arriving passengers at the airport. The Dunmu mission had 6 days of quarantine at Zuoying Naval Base, that's more than enough time to test all 744 members.

The ROCN should continue its efforts to uncover the source of the ROCS Pan Shih outbreak. Only when this is achieved can better preventive measures be implemented. This COVID-19 outbreak has already caused the navy to lose two of its brightest and most promising admirals and potentially affect its succession plans for up to two decades. It can disrupt the Indigenous Defense Submarine program and it has yet again tarnished the reputation of the Navy. Let's hope it does not claim any lives.

COVID-19 : Radical Changes For Naval Operations And Future Ship Designs Needed




Coronavirus by TP Heinz via Pixabay




As I write, the coronavirus pandemic which began as a mysterious respiratory illness in Wuhan City of China late last year has now engulfed the whole world with more than 1.4 million infected and more than 82000 deaths. The disease is officially known as COVID-19 ( coronavirus disease 2019 ) and the virus responsible for the illness is the SARS-CoV-2 ( Severe Acute Respiratory Syndrome Coronavirus 2 ).

Symptoms of the infection can range from asymptomatic to being a flu-like illness with malaise, fever, cough and dry throat, to severe respiratory distress requiring critical care. Being a viral illness meant that there is no effective treatment against it and it is largely left to the immune system to deal with the infection. Any medical intervention is therefore limited to providing life support and preventing further spread of the contagion.

Since the virus spread by means of droplets and surface contact, conditions of crowding and close person-to-person contact would facilitate its transmission. It was therefore not surprising that in Jan 2020 the Diamond Princess, a cruise ship which carried a total of 3711 passengers and crew, became a hotbed for COVID-19 transmission. It was quarantined at the Japanese port city of Yokohama since early February but because of poor, inadequate and perhaps ineffective infection control onboard, the total number of confirmed cases of COVID-19 eventually reached 712 with 567 passengers and 145 crew members infected. 12 had died.

Now the living conditions onboard a warship is not much different from those onboard a commercial vessel. Space is always a premium on a ship. Confining a large group of people to a small area for an extended duration is the prime recipe for a highly contagious disease to spread. During a pandemic, all ships, merchantman or man-of-war, are simply floating incubators, epidemiological time bombs waiting to explode. With the news that the nuclear-powered attack carrier USS Theodore Roosevelt ( CVN-71 ) has been ravaged by the coronavirus and is now anything but war capable, we know that even the world's mightiest navy is not immune to this health menace. Is there anything that can be done to minimize the risk of a COVID-19 outbreak onboard a warship? Of course there are, but it would mean many of our traditional habits and the way we conduct our businesses and carry out our missions would have to be modified or changed drastically. Perhaps every future ship design would have to include special areas for medical treatment and isolation and even berthing arrangements and living quarters have to be redesigned.

As a case study we can look to the USS Theodore Roosevelt to appreciate what a tiny virus can do to a large warship in a matter of days.

The Grounding Of A Carrier



The Roosevelt Carrier Strike Group ( CSG ) comprising of the aircraft carrier USS Theodore Roosevelt and its surface and submarine escorts including the guided missile cruiser USS Bunker Hill ( CG-52 ) and several destroyers departed San Diego on 17th Jan 2020 for its Indo-Pacific deployment.

The CSG arrived at Apra Harbor, Guam, on 6th Feb after sailing across the Pacific Ocean. We can assume the sailors were granted their well deserved shore leave on Guam and they had also participated in various community relations activities over that weekend, such as interacting with young kids from a school, clearing and cleaning up a trail in a nature park, repainting of a veteran's memorial, and some other miscellaneous repairing and rebuilding projects.

It then sailed westwards and arrived at Da Nang on 5th Mar to commemorate the 25th anniversary of the normalization of US-Vietnam diplomatic relations, becoming the second US aircraft carrier to make a port call in Vietnam since the fall of Saigon in 1975. As it was a high profile visit, the CSG was met by a whole host of Vietnamese and US government and military officials including Adm. John C. Aquilino, commander of the U.S. Pacific Fleet, and U.S. Ambassador to Vietnam Daniel Kritenbrink. Needless to say, there were also plenty of functions and receptions for the senior ranks to attend both ashore on onboard ship. For the lower ranks, the usual community relations projects were unavoidable. Somehow the military just love these social out reach programs and they can never have enough of them.

After Da Nang, on 15th Mar the CSG deployed to the South China Sea and sailed with the America Expeditionary Strike Group and the 31st Marine Expeditionary Unit as a combined Expeditionary Strike Force. On 18th Mar the CSG even managed some joint exercise with aircrafts like the F-15C from the US Pacific Air Forces operating out of Kadena AFB in Okinawa with a B-52H thrown in.

By 24th Mar however, the first cases of coronavirus infection has been reported among 3 ship crew onboard the Teddy Roosevelt. The number of the infected increased to 8 just a day later. Most of the infected only showed mild symptoms but they were flown off the aircraft carrier to the US Naval Hospital Guam for further tests, evaluation and quarantine. To fight the worsening outbreak, the US Navy had by then ordered the diversion of the carrier back to Guam and to have all of her 4845 sailors and airmen tested for the coronavirus. Acting Secretary of the Navy Thomas Modly insisted that the carrier was still fully operational despite the disease outbreak but we known otherwise. How can a carrier be combat ready when it is tied at pier-side?

Unfortunately for the Teddy Roosevelt, the number of infected sailors just kept increasing exponentially. By the time the carrier docked at Guam on 27th Mar the figure had risen to 25 infected. Soon after it became 36, and then 70. Worried about the health and safety of the sailors and airmen onboard the carrier, the commanding officer Captain Brett Crozier wrote a memo to the naval high command pleading for help to contain the outbreak, specifically to authorize the removal of about 4000 ship crew to a land based facility for two weeks of quarantine while a skeletal crew remain shipboard to run and maintain critical systems and deep clean the ship. The problem was Guam being an island in the middle of the Pacific Ocean did not have means to quarantine 4000 people on land. The captain's memo was somehow leaked to the San Francisco Chronicle and before anyone knew, the entire world had learnt about the Roosevelt's predicament.

 As a result of his plea and the publicity it generated, arrangements have been made to transfer about three thousand sailors ashore for quarantine. Not all could be evacuated as a skeletal crew had to remain onboard to operate critical systems that could not be shut down, like the Roosevelt's two Westinghouse A4W pressurized water nuclear reactors. Security and fire fighting details and a few hundred ship crew will have to remain onboard to deep clean the carrier which was estimated to take about 10 days. One thousand had left the ship on 1st Apr, with more to follow. It generated a lot of unhappiness among the local population of Guam who were rightly afraid that the sailors would introduce the coronavirus to their island.

So far all the infected personnel are medically stable and do not require hospitalization, ventilator support or critical care. Nobody from the Roosevelt has yet died from the infection but the captain's actions would eventually cost him his job. On 2nd Apr Acting Secretary of the Navy Thomas Modly relieved Capt Brett Crozier of his command citing loss of confidence and lack of leadership in times of crisis. He left his ship amidst a rousing send off by the ship crew, who clearly believed that their commanding officer had acted with their safety and well being at heart. By then the number of infected had already reached 114.

By 5th Apr Defense Secretary Mark Esper told CNN there were 155 infected. Even the poor captain himself had come down with the infection and is currently in quarantine. He had shown symptoms before he left his command.

The latest twist of this saga was that Thomas Modly himself was forced to resign as the acting secretary of the Navy on 7th April, a day after he described Capt Crozier as " too naïve or too stupid " to be in command, in a speech given during his visit to the aircraft carrier. The abrupt manner of Capt Crozier's dismissal as the commanding officer without going through a board of inquiry and due process was also a sticking point among naval personnel. The latest infected numbers on 7th Apr stood at 230 and it will surely go up in the coming weeks.*

As anyone could see, in about slightly more than a week, there were more than two hundred personnel who contracted the virus and the aircraft carrier is effectively non-operational being confined to port with more than half its compliment disembarked and on quarantine. We might never know how the virus first infected the ship, but a common assumption was from the 5 day port visit to Da Nang ( 5th - 9th Mar ). With the bulk of its crew now in quarantine, I suspect the Roosevelt's COVID-19 cases will peak in two weeks though new cases will continue to emerge sporadically for several more weeks since not all ship crew could be quarantined at the same time.

The good news is that since most of the ship's compliment are young and presumably healthy, most of Roosevelt's COVID-19 cases should recover with hopefully minimal complications. And once these people recover, they should have immunity against the coronavirus and they can even be deployed to provide care for their COVID-19 stricken compatriots without the need for those cumbersome personal protective equipment! They can also be a reliable donor source for the promising but not yet FDA-approved convalescent plasma therapy where the neutralizing antibodies against the coronavirus present in the plasma of recovered patients is transfused to help the acutely infected recover. In the unlikely event that a huge proportion of the ship crew eventually acquires the infection and the herd immunity threshold ( HIT ) is reached, the rest of the uninfected members will then be protected. The problem is this coronavirus outbreak is so new that nobody really knows what its HIT is. For measles, the HIT is between 90 to 95% to achieve herd immunity. Other less contagious diseases have lower HIT.

* 10 Apr - infected ship crew now hits 416. 3170 tested negative with 1164 results still pending. One sailor in ICU.

* 11 Apr - 92% ship crew tested. 550 positive, 3673 negative. 3696 moved ashore.

* 13 Apr - 585 infected. One death.

* 15 Apr - 615 infected. Majority asymptomatic ( 350 ). Chief Petty Officer Charles Thacker identified as sailor who died.

* 23 Apr - 840 positive. 4098 negative. 4234 moved ashore. 88 recovered. Tests completed.

* 28 Apr - USN COVID-19 Update website says 940 active cases, 29 recovered. Change in reporting parameter means only those with 2 successive negative tests count as recovered.


Infection Control Measures For COVID-19


To prevent personnel from acquiring and spreading COVID-19 onboard warships especially during deployments of prolonged duration, navies have to completely change the usual way peacetime naval operations are conducted.

As COVID-19 numbers keep rising in every country which can only mean there is sustained local / community transmission of the coronavirus, it is inevitable that some military personnel would have been infected as well. Whereas the ground and air force personnel could be immediately isolated and sent home or quarantined at a designated facility when found to be infected, the same arrangements could be impossible for naval personnel during a major deployment. Here are some changes that can potentially make a difference in the prevention of contagion onboard deployed ships.


Defer Unnecessary Trainings And Deployments


Just as the general public had been told to avoid and defer all unnecessary travels, the navy should also limit their fleet deployments to those that are of absolute necessity. All training deployments should be deferred until the pandemic has run its course. All chest-thumping / show-of-force type operations like those Freedom of Navigation operations should cease immediately. Training exercises can be postponed. If it is about saving lives like search and rescue missions, medical relief missions for the pandemic, or if the sovereignty or survival of the nation is at stake, like nuclear deterrence missions, proceed with caution.


Pre-Deployment Quarantine


The incubation period ( time between exposure to the development of symptoms ) of the SARS-CoV-2 virus is said to be between 2 to 7 days with a mean ( average ) of 4 days. In some cases the incubation period can be as long as 14 days. In order to ensure all embarked ship crew are healthy and not carrying or incubating the virus, they should be put to 14 days of pre-deployment quarantine. It should preferably be done at a base facility where there are rooms with attached toilet and shower, one individual to each room. There should be daily temperature checks and the monitoring of symptoms.

Any individual who develops fever or flu-like symptoms during this 14 day isolation period will have to be thoroughly checked for COVID-19 infection. Only if the individual is well and symptom free at the end of the 14 days can he or she be allowed to embark for deployment.


Vessel Preparation For Deployment


While the ship crew are under pre-deployment quarantine, the usual routine pre-sailing ship preparation will perhaps have to be undertaken by their squadron mates. Fuel, ammunition and food supplies have to be loaded, preferably in quantities sufficient to last the entire deployment if practicable. Such stores should be sanitized prior to loading onboard ship with the appropriate method, disinfectant spray, ultraviolet light etc. Medical supplies including personal protective equipment, medications, diagnostic equipment will have to be catered for. The ship should be deep cleaned prior to the embarkation of those who passed quarantine.


Special Measures When Underway


Ship crew should refrain from group gatherings like briefings and meetings as much as possible. They should try to maintain a physical distance of at least a metre from each other if practicable. Meal times should be staggered to avoid having large groups in the mess hall. The use of recreational facilities like the gym and ward rooms should similarly be regulated to maintain physical distancing.

Since ship systems need to be manned continuously once underway, the crew would have been organized into different teams to work in shifts. Members of different teams should also refrain from mingling with each other after-shift so that in case any team member is down with an infection and the entire team has to be in quarantine, at least the other teams would not be affected.

Another important area to note is movement of personnel between different vessels of the task group should be prohibited. Similarly transfer of personnel in and out of each ship should also be limited to medical or other emergencies only.


Avoiding Unnecessary Port Calls


This will be tough as port calls are frequently the highlight of every deployment. Who does not like the opportunity to visit a foreign city and experience a different culture even if it is only for a few days? Many things happen during port calls as ships replenish their depleted food supplies and take on fuel if necessary. The host country might organize a reception ashore for the ship's company and then the ship will have to reciprocate by hosting a shipboard reception during which lots of guests and ship officers and crew will mingle and party. There is no doubt that such functions are standard naval protocol and can foster the development of bilateral ties, friendship and camaraderie. They are also potential hotbeds for COVID-19 transmission and should be banned altogether during this pandemic.

It is also a common practice for navies all over the world to conduct community relations events or community outreach programs whenever the ship docks at a foreign port. So visiting some orphanage or old folk's home, repainting a school, cleaning up a beach or a park .... becomes mandatory for the lower ranks. These activities can frequently bring real benefits to the local communities, touch lives and also hopefully benefit the participants by accentuating their sense of humility seeing and serving the less fortunate. Again, during an epidemic or pandemic, these relations building activities should cease completely. The opportunity to serve will always remain and can be engaged again after the disease outbreak is under control.

For short deployments ships should therefore be as self-sufficient as possible and avoid port calls altogether. For longer deployments, port visits should be limited to taking on and off-loading essentials and no shore leave should be granted. No visitors should be allowed onboard the ship unless of absolute necessity, like the harbor pilot to ensure safe navigation into and out of the port. Even then keep a safe physical distance and provide the pilot with a surgical mask if he is not already wearing one and remind him not to touch anything. And don't forget to clean up the bridge after he leaves.


Good Personal Hygiene


Perhaps the single most important measure against the spread of the coronavirus is the practice of good personal hygiene. An infected person will be shedding a lot of the virus through the nasal mucous and phlegm from the throat. When he or she sneezes or coughs, droplets can land on surfaces or be directly inhaled by others in close proximity. An infected person's hands will be also likely be heavily contaminated with the virus if he or she wipes the nose without subsequently washing the hands.

With the understanding of how the virus spreads, frequent hand washing with soap or the use of disinfecting hand rubs are therefore the best defense against getting infected. Keep your hands clean and try not to touch your face or rub your eyes because that's how the virus enters your body - through the eyes ( conjunctiva ), the nose or the mouth via your dirty hands.

Wash your hands before you have your meal and also after you have visited the toilet. Coronaviruses can be shed through the feces of an infected person. Sometimes viral RNA can be detected in the feces long after they have recovered from the illness, though it could be just viral genetic material and not the viable virus itself. So shared heads / communal toilets must be kept clean. Common areas should be regularly cleaned with disinfectants.





Masks


There is now sufficient evidence to suggest that pre-symptomatic spread of the coronavirus can occur. Universal mask wearing might be a good idea for all personnel onboard the ship for self protection and for protecting others should one fall sick and unknowingly spread the virus during the incubation phase. Exemptions can be made for those in anti-flash gear.

A properly made disposable surgical mask has a waterproof middle layer that prevents respiratory droplets from a sick person from escaping and infecting other people. An N95 type respirator is not necessary for non-medical use. Not only are some types of N95 mask not fluid resistant, they are also very uncomfortable to wear and may result in the wearer touching the face much more frequently to adjust the uncomfortable mask resulting in higher risk of infection.

Masks alone cannot prevent COVID-19 infection and must be used in combination with other measures for infection control. Between them, hand washing and physical distancing are still more important.

There is currently a worldwide shortage of masks, surgical as well as N95, as the pandemic rages. Most mask manufacturing countries have restricted and then banned their export altogether with the hope of keeping whatever is available for themselves. Since we are nowhere even near the peak of the pandemic, mask shortages will be the order of the day for many many months to come. Conserve your masks and save your stock for later when shit really hits the ceiling. Quartermasters and medics guard your mask supplies like gold and ration them carefully.

Unless you have an unlimited supply, do not discard your mask after a single use like what most would do before. Instead, keep the disposable mask clean and you can reuse it for 2 or maybe 3 days. When removing the mask for later use, remember not to touch the outer, potentially contaminated surface of the mask. Hold it by the straps and keep it in a clean zip lock bag. If surgical masks are not available, studies have shown that even reusable / washable cloth masks can be better than no mask at all.



Impact On Future Ship Designs


As the world population continue to grow and our insatiable demand for resources drive us towards large scale exploitation of nature, human exposure to wild animals will increase exponentially and with it the number of zoonotic diseases. A zoonosis is an infectious disease caused by a pathogen that has jumped from its usual animal host to humans. Some recent examples include Marburg Haemorrhagic Fever ( 1967 W. Germany ), Ebola virus disease ( 1976 Sudan, Congo), Hanta virus pulmonary syndrome ( 1993 Four Corners, US ), H5N1 Avian Influenza ( 1997 Hong Kong ), Nipah virus disease ( 1998 Malaysia ), SARS ( 2002 Hong Kong ), MERS ( 2012 Middle East ) and COVID-19. These emerging infectious diseases frequently cause severe symptoms and carry with them high mortality rates.

To cater for these ever frequent disruptive epidemics, naval architects should design future warships with special considerations for disease prevention and treatment. Living quarters and work spaces could be bigger. Hot bunking should be a thing of the past. Every sailor should have his or her own room, even if it means it has to be capsule hotel style, small and cramped. The current bunking arrangement of segregation by rank, that is, Officer's mess, Petty Officer and Chief Petty Officer's mess, Junior Rank's mess, should be reviewed. It involves too much movement and intermingling of ship personnel. Instead ship crew should be divided into watch keeping teams and personnel from the same team bunk together, regardless of rank. So a ship can have several such sleeping quarters for different watch keeping teams and each should have its own heads, shower, laundry facilities, mini pantry, recreation area and maybe even a mini gym.

The ship should have dedicated rooms for medical treatment and isolation in case of a disease outbreak onboard the ship. Each isolation room should have its own toilet and sink so that the crew member in isolation need not get out of the room to wash or relieve himself. This requirement can be tough to meet on a small platform like Singapore's Victory-class missile corvette which is 62m long and has a displacement of 595 tonnes, but nobody says you should build designs like these anymore.

The future ship should also have advanced communications links between different compartments to transmit real time video and audio signals to reduce the need for the ship crew to physically gather for meetings and briefings.

The ultimate goal could perhaps be to eliminate the human crew altogether. If we can have a frigate-sized unmanned surface vessel that is remotely controlled and unmanned droid-carrying amphibious assault ships, we will not have to worry about diseases and outbreaks. In the event of war, there will be no casualties to worry about either! A Little far fetched but this day may arrive sooner than we think.

And lastly, for our readers whose town or city might be in lock down due to the COVID-19 pandemic, a gentle reminder to STAY HOME and help flatten the epidemiological curve in your country.

Gimme STOVL : Singapore Decides On The F-35B

On 9th Jan 2020, the Defense Security Cooperation Agency ( DSCA ) announced that the US Department of State had just approved a potential Foreign Military Sale ( FMS ) to Singapore of up to 12 F-35B Short Take-Off And Vertical Landing ( STOVL ) aircraft and related equipment for an estimated cost of USD 2.75 billion.

Singapore's interest in the F-35 Joint Strike Fighter ( JSF ) program had began in Mar 2004 when it became a security cooperative participant. For a very long time the Singapore government seemed contented to just monitor the progress of the JSF program as it matured. There were numerous instances when defense analysts and news agencies had indicated that Singapore might be ready to acquire the F-35 but the JSF deal had remained elusive. It even failed to materialize during Prime Minister Lee Hsien Loong's visit to the White House in 2016, at the invitation of President Obama.

All that changed in Jan 2019 when Minister for Defense Ng Eng Hen announced that Singapore had identified the F-35 as a suitable candidate to replace its ageing F-16 fighters and would be acquiring a small number of the stealthy 5th generation fighter for a full evaluation of its capabilities and suitability before deciding on a full fleet.

By Mar 2019 it was revealed that Singapore would be requesting for an initial four F-35 JSF with an option for eight more, variant unspecified. Months of media speculation followed, but we now know that Singapore has selected the F-35B, the STOVL version which is the most expensive among the three F-35 variants.


The F-35 In A Nutshell


At a cost of more than USD 400 billion, the F-35 Joint Strike Fighter program is the most expensive weapons program the world has seen. Its aim is to produce an affordable fifth generation multi-role stealth fighter to replace various legacy fighters of the US and its closest allies. The F-35 comes in three variants, all having similar performance characteristics and share commonality in parts and processes in order to capitalize on the economies of scale to reduce procurement and sustainment costs. The variants cater to the differing service-specific requirements by the Air Force, Navy and Marines. To put it simply, the F-35A is the conventional take-off and landing ( CTOL ) version for the Air Force, the F-35B is the STOVL version for the Marines while the F-35C is the carrier variant ( CV ) for the Navy.

The JSF program is plagued with multiple issues from technical deficiencies, delays to cost overruns and the root of its many problems can be traced to its developmental concept of " concurrency ". The idea that in an era where new technology is emerging at an unprecedented rate, an aircraft design will be obsolete the moment its development has concluded. In order to field aircrafts with the latest technologies earlier, they will be produced before tests and trials are completed and eventually upgraded along the way to the latest standards.

Despite its troubled past, the JSF program has matured over the years and has seemed to turn around to deliver what was originally promised - affordable stealth. Unit prices have continuously fallen in the past several years due in part to an increase in production efficiency and to the economy of scale from an increase in aircraft orders.



New Capabilities for the RSAF



Acquiring the F-35B will bring two completely new capabilities to the Republic of Singapore Air Force ( RSAF ) - STOVL and Stealth. Between the two, I would believe STOVL is the most unique since there is not another country in the Asia Pacific region save Japan that has confirmed plans for such a capability.

Stealth technology can become an increasing crucial capability to have as Singapore's regional near-peer rivals begin to acquire sophisticated aircrafts like the Su-30 and Su-35 which can out-class even the RSAF's most advance fighter like the F-15SG. It can ensure higher survivability of the aircraft and pilot in an extremely hostile threat environment.

STOVL is equally important to ensure sustained generation of air operations in the event of disruptive attacks to Singapore's airbases. Aircrafts with short field capabilities can be dispersed and hidden more effectively on the ground and can have alternative means of take-off and landing even when the conventional runway is made unavailable by a pre-emptive strike.

In addition, having STOVL capable jets means that should the Singapore Navy decide to replace its Endurance-class landing ship tank with something bigger like the Endurance-160 Joint Multi-Mission Ship, these helicopter assault ships can be potentially modified for F-35B operations as well, converting them into light aircraft carriers. The JMMS then becomes mobile airfields at sea, projecting airpower and will be an added insurance against complete annihilation through a coordinated attack on Singapore's land based runway infrastructure.

STOVL : Unique Capability At A Price



The F-35B is not just the only modern STOVL jet fighter that is currently in production, it is also capable of supersonic flight. Its predecessor the AV-8B Harrier II which is also STOVL capable is at best only sub-sonic. This short field and austere field capability is the unique selling point of the F-35B but it comes at a price.

The requirement for STOVL capability in the F-35B meant that its design is the most complex among the three F-35 variants. It needed a proprietary shaft driven LiftFan propulsion system and an engine nozzle that can swivel 90 degrees when in STOVL mode. This in turns imposes limits on the size of the internal weapon bay and the internal fuel capacity which translates to a reduction in the weapons payload and combat radius. It even imposes structural limits and the F-35B has the lowest maximum g-rating among all the variants. Understandably the unit cost of the F-35B is also consistently the highest compared to the other variants.

So in view of the various technical setbacks peculiar to the F-35B, is the STOVL a capability worth having? The answer has to be an absolute yes if you intend to have fixed-wing flight operations on non-catapult equipped aircraft carriers like the navies of the United kingdom, Italy and Japan. It will also be a resounding yes for a small nation like Singapore which lacks strategic depth and has air bases that can be vulnerable to a determined attack by rocket, artillery and mortar fire from across its boarders.

Looking at the broader picture, the non-STOVL variants, the F-35A and the F-35C, also suffered similar functional and structural setbacks albeit to a lesser degree simply because of the requirement that all three variants had to have shared design and components with various degrees of commonality. In other words, the Marine Corps' insistent that STOVL capability must be included in their variant essentially resulted in the Air Force and the Navy having to accept compromises on their variants too. Compared with its 4th generation peers that it is meant to replace, the F-35 is frequently found to be a little lacking in maximum speed, agility, range and payload. The saving grace is that the F-35 more than makes up for all these shortfalls through its superior suite of sensors, avionics, sensor fusion and low observable technology, all of which shall be briefly reviewed below.

Very Low Observable



The F-35 is a fifth generation fighter which, according to its main contractor Lockheed Martin, is defined by the combination of Very Low Observable ( VLO ) stealth, advanced sensors, information fusion and network connectivity within a supersonic, long range and highly maneuverable aircraft.

VLO stealth technology is an integral part of the F-35's design. The clever use of shapes to deflect radar waves, the careful selection of materials that can dissipate radar energy and the internal carriage of weapons, fuel and embedded sensors means that it is much harder for the enemy to detect the F-35. The radar cross section ( RCS ) of the F-35 is the smallest when it is viewed head-on but less so when viewed from the side and even worse when viewed from the rear so it is hardly all-aspect stealth. It is also mainly stealthy in the X-Band, the most common frequency used by fire control radars and less so in other lower frequencies.

As much as it is hyped, stealth is not equivalent to invisibility to radar but rather a significant reduction in the detectability. Any advantage a stealth aircraft has can be undermined by several means including the use of infra-red search and tract technology to detect the heat signature of a stealthy aircraft and through the use of radar operating in frequencies other than the X Band, like L-Band or VHF.

While the level of stealth afforded by the F-35 is not at the same level as that of the F-22 Raptor, it is less costly to maintain as there is less dependency on expensive radar absorbing coating and that is definitely a good thing.


Distributed Aperture System



The electro-optical Distributed Aperture System ( DAS ) is a new generation of sensor system currently only found on the F-35 consisting of six identical high resolution mid-wave infrared ( MWIR ) sensors mounted all around the airframe in such a way as to provide an unobstructed 360 degree coverage for enhanced situational awareness. The DAS sends high resolution augmented reality imagery in real time to the pilot's helmet mounted display allowing them to see their surrounding environment with clarity day or night. It can provide functions including missile detection and tracking, launch point detection and countermeasures cueing, aircraft detection and tracking ( situation awareness IRST and air-to-air weapons cueing ), day and night navigation, and precision tracking of friendly aircraft for tactical maneuvering. Designated the AN/AAQ-37, the DAS is developed by Northrop Grumman Electronic Systems and has its fair share of teething problems though they have largely been resolved by now. More than a thousand DAS units have been delivered by Northrop Grumman so far, for installation on aircrafts up to and including LRIP Lot 14.

In 2018, Lockheed Martin announced that Raytheon has been selected to develop the next generation DAS which will be expected to have better performance, higher reliability and lower sustainment costs. They will be installed on all Low Rate Initial Production ( LRIP ) Lot 15 aircrafts for delivery in 2023.

Electro-Optical Targeting System

 
 
The AN/AAQ-40 Electro-Optical Targeting System ( EOTS ) is an internally mounted advance MWIR targeting sensor developed by Lockheed Martin Missiles and Fire Control Sensors. The EOTS integrates targeting forward looking infrared ( TFLIR ), infrared search and track ( IRST ), laser range finder / designator and laser spot tracker functionalities to provide the F-35 with precision air-to-air and air-to ground targeting capability. The low drag, stealthy EOTS is integrated into the F-35's fuselage ventrally just behind the nose cone with a faceted sapphire window and is linked to the aircraft's central processor by a high-speed fiber-optic interface. Utilizing the mid-wave portion of the IR spectrum provides a sharper image and is less susceptible to target obstruction by smoke or haze.
 
Lockheed Martin has already developed the next generation Advanced EOTS which will provide a range of multi-spectral sensing options including high-resolution mid-wave infrared, short-wave infrared and near infrared. It will have enhanced image detector resolution, high-definition TV and IR marker. The advanced EOTS will  be available for integration on the F-35's Block 4 development and will sharpen the F-35's close air support capabilities.

Multi-Mission Active Electronically Scanned Array Radar



The AN/APG-81 active electronically scanned array ( AESA ) radar installed on the F-35 is developed by Northrop Grumman Electronic Systems. It is the next generation version of the AN/APG-77 AESA radar that was first fielded on the F-22A Raptor. It allows the F-35 to engage air and ground targets at long range and also has significant electronic warfare and intelligence, surveillance and reconnaissance functions. Its solid state technology and elimination of moving parts ensure better reliability compared with mechanically scanned antenna radars. The AN/APG-81 also has inherent low probability of intercept ( LPI ) features to minimize the likelihood of its emissions being usefully detected by enemy airborne or ground based receivers.

The AN/APG-81 is designed to operate as a radar, an electronic support measures ( ESM ) receiver, and a jammer. It has passive and active air-to-air and air-to-surface target detection, track and identification capabilities. It also enables synthetic aperture radar mapping, ground and sea moving target detection and track and air-to-surface ranging. As good as it is, the AN/APG-81 is still lacking a wide field capability in its sea search mode, being able only to seek out a narrow zone in front of it. This deficiency will be rectified in the F-35 Block 4 upgrade being carried out from 2019 to 2024. Together with the integration of partner nation ordnance like Norway's Joint Strike Missile which will also happen during Block 4 upgrades, the maritime strike capabilities of the F-35 will be greatly enhanced.

Integrated Communications, Navigation and Identification Avionics



The AN/ASQ-242 integrated communications, navigation and identification ( CNI ) avionics suite developed by Northrop Grumman is designed to provide the F-35 with secure, electronic countermeasures resistant voice and data communications; precise radio-navigation and landing capabilities; self-identification and BVR target identification; and network connectivity with off-board sources of information. All these at a reduction in size, weight and power requirements compared with legacy systems.

The CNI sub-systems includes the Multifunction Advanced Data Link (MADL), Link 16 data link, single-channel ground and airborne radio system (SINCGARS), IFF interrogator and transponder, HAVE QUICK radio, AM, VHF, UHF AM, and UHF FM radio systems, GUARD survival radio, radar altimeter; tactical air navigation (TACAN), inertial navigation system ( INS ), anti-jam GPS, instrument landing system ( ILS ) for conventional runways and aircraft carriers, the Joint Precision Approach and Landing System (JPALS), and the TADIL-J tactical digital information link with Joint-Variable-Message-Format (JVMF) communications.

The CNI system provides inter-operability with existing legacy military and civilian communications, radio-frequency navigation, and identify friend or foe ( IFF ) / surveillance systems. It is also interoperable with the appropriate civilian systems for US and European airspace operations.


Electronic Warfare / Countermeasures System



The AN/ASQ-239 electronic warfare / countermeasures ( EW/CM ) system developed by BAE is designed to provide the F-35 with a high degree of air-to-air and surface-to-air threat detection and self protection. It can search, detect, identify, locate and counter radio-frequency and infrared threats.

Its advance avionics and sensors enables real time, all aspect, broad-band coverage of the battlefield, maximizing detection ranges and giving the F-35 pilots evasion, engagement, countermeasure or jamming options. In other words it allows the F-35 to dominate the electromagnetic spectrum.

The EW subsystem serves as a signals collector which provides radar warning, identifies the geolocation of electronic emitters, tracks multiple aircrafts simultaneously, provides high gain electronic support measures ( ESM ), high gain electronic countermeasures ( ECM ) and high gain electronic attack via the AN/APG-81 radar's multifunction array.

The countermeasures subsystem provides multiple self-defense responses, including pre-emptive and reactive techniques, based on available expendable payload ( MJU-61/64/68/69 IRCM flares and ALE-70 RFCM fiber-optic towed decoys ) and threat-specific self-protection plans.

Lockheed Martin claims that due to the inherent, built-in electronic warfare capabilities the F-35 does not require a dedicated electronic attack aircraft to support it. That could potentially free up other aircraft to perform electronic attack missions to protect less stealthy aircraft. This organic jamming capability of the F-35 through its AESA radar, teamed with advanced jamming algorithm packages, can potentially provide 10 times the jamming power of legacy aircraft.

Sensor Fusion



The F-35's advanced sensor fusion allow pilots to harness information received from all their onboard sensors to create a single integrated picture of the battlefield. Such information is then automatically shared with other pilots and command and control operating centers on their network via a secure datalink such as the Multifunction Advanced Data Link ( MADL ).


Helmet Mounted Display System



The F-35's Gen III Helmet Mounted Display System ( HMDS ) is an interface that provides pilots with intuitive access to vast quantities of flight, tactical and sensor information for advanced situational awareness, safety and precision. All the information that the pilots need to complete their mission is projected onto the helmet visor rather than on a traditional Heads-up Display. It reduces the pilot's workload and increases responsiveness. In addition, real-time imagery from the DAS's six IR cameras streamed to the helmet allows the pilot to virtually look through the airframe providing the equivalent of x-ray vision. The HMDS enables pilots to target weapons by looking at and designating targets. It does so by tracking the position of the helmet to determine the gaze of the pilot and supplies information such as target identity and distance. This off-boresight targeting capability is especially useful when used in combination with modern all-aspect air-to-air missiles like the AIM-9X. The helmet also offers visor-projected night vision and eliminates the separate use of night vision goggles.

All these functionality comes at a price though. The F-35's super helmet costs a whopping $400000 and has to be custom made for each aviator to ensure a precise fit for the tracking system to work accurately. Rockwell Collins, the maker of the helmet, estimated that every F-35 on order will need 2.5 to 3 helmets over their service life due to wear and tear, damage and pilot attrition and replacement.

Auto Ground Collision Avoidance System



Work done on the F-16's auto ground collision avoidance system ( AGCAS ) has enabled fielding of this revolutionary flight safety system on the F-35 seven years earlier than originally scheduled. The AGCAS integration could have began as early as 2019 and has been estimated to prevent more than 26 ground collisions over the service life of the F-35.



Autonomic Logistic Information System


The Autonomic Logistic Information System ( ALIS ) of the F-35's fleet managing system is the web enabled IT infrastructure that was meant to support cost effective sustainment throughout the life time of the aircraft. It however did not live up to expectations and has been blamed for, among other things, the F-35's poor mission capability rates in the past. It will be replaced by a new system known as Operational Data Integrated Network ( ODIN ) starting from late 2020 which it is hoped will be more user-friendly, secure and less prone to error. Full implementation will be expected by 2022.

 


Core Missions



Armed with such a dazzling array of advanced sensors and capabilities, the multi-role F-35 can be tasked to perform the following missions :

Air superiority - offensive and defensive counterair
Strategic attack / Air Interdiction against high value strategic and mobile targets
Close air support
Suppression / destruction of enemy air defense
Electronic Warfare
Intelligence, surveillance and reconnaissance
Extended surface warfare - maritime strike  ( with future F-35 Block 4 upgrades )

Singapore's Cautious Buy



The F-35 has come a long way since the commencement of the JSF program in 2001. All three variants have achieved initial operational capability ( IOC ), with the F-35B of the Marine Corps first to do so in 2015 with Block 2B software which allows for initial warfighting capability. It was followed by the USAF's declaration of IOC for the F-35A in 2016 with the Block 3i software and lastly the USN for the F-35C with the Block 3F full warfighting capability software by Feb 2019. The long drawn system development and demonstration ( SDD ) phase has concluded in April 2018 and a new phase known as Initial Operational Test And Evaluation ( IOT&E ) has began. The successful conclusion of the IOT&E, initially due in Jul 2019 but currently delayed by problems relating to the Joint Simulation Environment facility, will pave the way for the commencement of full rate production ( FRP ).

Production numbers are peaking with a record number of 134 F-35s delivered in 2019 and that figure is expected to be surpassed in 2020. The combined all variants production numbers have reach 491 aircrafts by December 2019. The unit cost of all variants have continued to fall for the past few years and the latest LRIP Lot 14 F-35B for delivery in 2022 has a unit cost of S101.3 million, significantly lower than the LRIP Lot 11's $115.5 million or the LRIP Lot 10's $122.4 million. With the latest LRIP Lot 12 to Lot 14 F-35A CTOL variant Lockheed Martin even managed to lower the unit cost to their promised less than $80 million target, a year ahead of schedule.




Yet the F-35 has still not ironed out all its teething problems, though it probably will in time to come. Also, although unit prices have steadily fallen, operating costs have not. At between $34000 to $36000 per hour, the F-35 cost significantly more to operate compared with the legacy aircrafts it was meant to replace, like the F-16 ( $24000 per hour ) or F/A-18 ( $24400 per hour ). The fatal crash of a F-35A of the Japan Air Self Defense Force in April 2019 would have added uncertainties to its air worthiness and safety record but it was eventually attributed to spatial disorientation of the pilot. The event nonetheless delayed Singapore's decision making process to buy the F-35. It is therefore not surprising that the Singapore government only committed itself to an initial four aircraft purchase, with an option for eight more. It is not even enough to form half a squadron, and as declared the initial four aircrafts will be used for tests and evaluation. It will be crucial to find out, among other things, if the Pratt & Whitney F135 engine can actually produce enough vertical thrust in the typically hot and humid environment of Singapore to allow for hovering and vertical landing of a laden F-35B.


 

STOVL Above Stealth



Singapore's selection of the F-35B demonstrates that above all, it values the STOVL capability and the basing flexibility and operational flexibility it brings. If stealth and sensor fusion were its main focus, it would have chosen the F-35A CTOL variant like most other non-US operators of the F-35. It is even willing to trade physical attributes like range, payload and agility for the inclusion of STOVL, which in retrospect makes a lot of sense. The greatest strength of the F-35 is not about its absolute speed, rate of climb, range on internal fuel, sustained turn rate, maximum payload or maximum g-rating. Many legacy 4th generation fighters do better on those parameters. The real value of the F-35 is its survivability in an access denied high threat environment and its superior networking capability thanks to its VLO technology, all-encompassing sensors, organic self-protection mechanisms and connectivity. The planned closure of the Paya Lebar Air Base after 2030 will have the Republic of Singapore Air Force operating out of its three other remaining air bases, Sembawang, Tengah and Changi. That makes the adoption of STOVL capabilities very sensible as it can mitigate some of the risks of air operations disruption from airfield denial attacks.

In the United States, the F-35B has not only changed the way which the Marine Corps' Amphibious Ready Groups conduct their missions, it has given them new blue-water capabilities in the absence of a carrier nearby. The LHAs and LHDs have suddenly turned into mini-carriers in their own right and find themselves taking on missions normally assigned to carrier strike groups. These are mind boggling stuff that was just impossible a few years ago.

What Happens Next



The Department of State has in principle given the green light for Singapore to acquire up to 12 F-35B fighters but Congress must still approve the deal. Congress was formally notified of the proposed sale on 9th Jan 2020 and has 30 days to review it before it is approved. Given the good bilateral relations between Singapore and the US and the fact that Singapore is a strategic friend and a major security cooperation partner of the US in the Asia Pacific region, the Congressional Note, a necessary FMS formality, will likely be approved without issues. With Congressional approval, final terms will be negotiated for the Letter of Offer and Acceptance.

Singapore may have deliberately timed its F-35 purchase to coincide with the end of LRIP and the beginning of full-rate production. Since current LRIP Lot 12 to Lot 14 for delivery between 2020 and 2022 are likely to have been fully allocated, the assembly of Singapore's initial four F-35B could be assigned to later production lots like LRIP Lot 15 / FRP. Whichever production lot they come from, Singapore is likely to receive the F-35B Block 4 with the latest software upgrades and enhanced warfighting capaibities.

All four initial F-35B are likely to end up at Marine Corps Air Station Beaufort in South Carolina where all international F-35B pilots and maintainers are trained. They will form a training detachment where the first batches of RSAF pilots and ground personnel will undergo training with their USMC counterparts from the Marine Fighter Attack Training Squadron 501 ( VMFAT-501 )  and other foreign entities from the UK, Italy and Japan.

Only when sufficient numbers of F-35Bs have been procured, such as when the addition option of eight F-35B have been exercised and sufficient pilots and maintainers trained will some of these new generation fighters be brought back to Singapore for integration with the rest of the Air Force. What follows will be the achievement of IOC and FOC.

The RSAF already has some of the assets and capabilities that will be essential for supporting 5th generation fighter operations, such as the Leonardo M-346 lead-in fighter trainer for pilot training prior to F-35 operational conversion and the Airbus A-330 Multi-Role Tanker Transport ( MRTT ) for aerial refueling during deployments. It is worthwhile to note that the F-35B ultilises the probe-and-drogue method for aerial refueling similar to all other USN and USMC fixed wing aircrafts, instead of the flying boom method common to USAF tactical fighters, including the F-35A. So apart from the MRTT, perhaps the refueling capabilities of the RSAF's ageing KC-130B and KC-130H might again be put to good use, provided they are still in service in the 2030s!

Sending A Message To China?



Hardly. The news media had it all wrong. While nobody apart from totalitarian and despotic regimes loves China, it does not mean that Singapore's F-35 buy is directed at China, or any other country for that matter, as the Ministry of Defence has claimed. This is especially true as Singapore does not have any territorial disputes with China and China is also one of Singapore's largest trading partners. But it does have a vested interest in ensuring its sea lines of communication remains secure and open so that trade flows are not disrupted.

The notion that Singapore can work together with the other F-35 operating countries in the Asia Pacific, namely Australia, Japan and South Korea, to contain China is also without merit. Why would Singapore want to get involved with the squabbles between China and each of these countries? Has it not had enough of its own problems?

Therefore this F-35 acquisition is just another routine force renewal exercise aimed at replacing the ageing F-16 fighters which have been in service with the RSAF since 1998. Nobody should really read too much into it or worry about it .... at least until the Joint Multi-Mission Ship is constructed.
