The Victory-class missile corvette ( MCV ) of the Republic of Singapore Navy ( RSN ) might be small but do not let its size fool you. At 530 tonnes, these tiny multi-role platforms are not much bigger than the fast attack crafts favoured by many small navies of the world but they do pack a huge punch and could pose a serious threat to much larger opponents.
Based on the MGB 62 design by German shipbuilder Lurssen Werft, in its original configuration, its impressive list of capabilities included anti-surface warfare ( ASuW ), anti-submarine warfare ( ASW ), anti-air warfare ( AAW ) and electronic warfare ( EW ), encompassing the domains of maritime surveillance / interdiction and confined / shallow waters operations.
First commissioned 30 years ago in 1990, the missile corvettes are fast approaching the end of their service life. The RSN plans to retire them by 2025 and replace them with a new class of warships known as multi-role combat vessels ( MRCV ). That timeline has since been revised and postponed for another 5 years to 2030.
We look at the history and evolution of the Victory-class missile corvette through some quirky facts that you may not have known.

It All Started With The MGB
The RSN ordered its first generation missile equipped vessels, the Sea Wolf-class missile gunboat ( MGB ) in 1968 and had integrated and commissioned them between 1975 and 1976. They were armed with the Gabriel anti-ship missile ( AShM ) of Israeli origin. The Gabriel was the world's first operational sea-skimming AShM and had already proven its worth during the Yom Kippur War of 1973 in the Battle of Latakia. The use of semi-active radar homing meant that the MGB would have to track the target with its fire control radar and issue guidance command to the missile in flight. The Gabriel consequently has a maximum range of only 20km, limited by the radar horizon.
Operating these warships with then rather complex weapon systems allowed the RSN to acquire the technological expertise and nurture a core group of combat officers and technical personnel who were able to effectively operate and maintain sophisticated weapons system and platforms. The experience and knowledge gained from the MGB acquisition and integration also gave the RSN confidence to define and design its next generation surface combatant, the missile corvette, based on its unique littoral operational requirements.
Maintaining The Technological Edge
Although the RSN was the first among the South East Asian navies to operate missile boats and the first to have successfully test fired an AShM in 1974, it quickly found itself operationally disadvantaged barely a few years later when a regional near-peer entity acquired a longer range AShM with active radar homing and advanced fire control radar. It was felt that the shorter range of the Gabriel represented a significant handicap and the RSN conducted a study in 1979 to build three 57m boats armed with longer range active radar homing missiles. Another option was to upgrade the existing MGB by removing two to three of the Gabriel missiles and replacing them with more advanced active homing missiles.
The decision to upgrade the MGB came in early 1983, but the RSN ditched the proposed 57m craft and instead decided in December 1983 on acquiring six larger 62m missile corvettes. The anti-ship missile system selected for both the MGB upgrade and the MCV was the McDonnell Douglas ( now Boeing ) RGM-84 Harpoon.
RSN's New Found Mission
Apart from being inadvertently caught up in a regional AShM arms race, justification for procuring the missile corvettes also came in the early eighties when the RSN, having lost its sense of purpose and direction after a long period of preoccupation with policing and patrolling the coastal waters of Singapore especially during the Vietnamese boat people refugee crisis, suddenly discovered it had a critical role to play in keeping Singapore's sea lines of communication ( SLOC ) open as the island nation's trade dependent economy, its energy needs and food imports were entirely reliant on the premise of free and open navigation on the high seas. This realization of the RSN's strategic role was accredited to Mr Peter Ho, then Head of Naval Plans Department, who examined Singapore's trade statistics and discovered the importance of the shipping lanes to the survival and security of Singapore.
In line with this new found vision and responsibility, the RSN could no longer remain a coastal navy contented with near shore operations. Bigger warships with better seakeeping characteristics would be required in order to operate effectively up to a thousand kilometers or more away from the home base. With a length of 45m and displacing just 270 tonnes the MGBs were really more suitable for littoral operations.
At the same time the threat that submarines posed to the trade routes became ever more real as regional navies modernize and either acquired, expanded or upgraded their submarine fleets. This meant that the corvettes would have to have anti-submarine capabilities as well, a first for the RSN.
The V-class MCV
The first corvette was built and launched in Germany in 1988 while the remaining five were constructed domestically by Singapore Shipbuilding and Engineering ( now known as Singapore Technology Marine ). The first three corvettes were commissioned in 1990 while the rest were commissioned a year later.
They all had names starting with the letter V - Victory, Valour, Vigilance, Valiant, Vigour and Vengeance. Apart from the first-in-class RSS Victory, the other 5 ships had their names chosen by the public through a name-the-ship competition in Jan 1988. The series of names that were pre-selected included RSS Vampire, RSS Vulcan and RSS Vendetta but the participants were free to submit other names as long as it began with the letter V. In those pre-internet days, the entry forms had to be distributed nationwide at major shopping malls, libraries and community centres. They also appeared in newspapers and even the Ministry of Defense's own publication the Pioneer magazine. By April, the RSN had received more than 24000 entries. The prizes were sponsored by the builder of the corvettes, SSE.
The six missile corvettes form the 188 Squadron / 8th Flotilla of the RSN based at Tuas Naval Base in the south-western part of Singapore. This year marks the 30th anniversary for the MCV as well as the 188th Squadron.

The Tall Mast
During the age of sail, the mast was an essential part of the ship whose purpose was to carry the sail and by virtue of its height the best position to display navigation lights, signal flags and the best position to place lookouts and snipers. The biggest sailing vessels frequently have multiple masts and they are usually constructed of solid timber.
Modern vessels in contrast have masts not to carry sails but to house electronic equipment necessary for navigation and warfighting in the case of naval vessels. Height still matters as many of these devices operate by line of sight principles and the higher up you position them the greater their effectiveness or the better the range. Navigation radar, fire control radar, surface and air search radar, electro-optic sensors, communications antennae, electronic counter-measure and electronic support measure devices are among the myriad of equipment found on or within the hollow structure of the mast proper. Naval vessels have the tallest masts. If you spot a ship from afar and it has a tall mast, chances are it would be a man-of-war.
The most striking thing a person would notice when looking at the profile view or the silhouette of the Victory-class corvette is the disproportionately tall mast in relation to the length of the hull. While the MCV has a length of 62m, the combined height of the main mast and auxiliary mast could reach about 36m above the waterline. It never failed to remind me of the World War II Japanese battleships with their pagoda superstructures.
It was as if the marine architects had taken the blue prints of a 1200-tonne corvette, kept all the weapons and sensors as it were, left the mast intact but had shrunken the hull. So you end up with a warship that packed the firepower of a corvette but housed in the body of a gunboat. After all, the MCV was based on Lurssen Werft's MGB 62 design with the MGB presumably meaning missile gunboat and 62 indicating the length of the design in meters.
The mast of the Victory-class MCV is so tall and is crammed with so many electronic devices that it has a tendency to make the corvette seem top heavy and perhaps contribute to a higher tendency to roll in adverse weather conditions. Having said that, the MCV has been known to roll more than 40 degrees both ways during a tropical storm, causing pots and pans to tumble in the galley and lookouts on the bridge to have to grip the railings tight. Yet, miraculously the corvette would right itself after each swell to see another day. After all the MCV hull is constructed of light gauge steel built around a special longitudinal framing system for ruggedness and good sea keeping characteristics, with the superstructure being constructed using marine grade aluminium alloy. Accordingly, the MCV is able to withstand conditions up to sea state 5. Kudos to the naval architects who designed the ship.

The Crooked Auxiliary Mast
In its original configuration before the Ship Life Extension Program ( SLEP ) upgrades, the MCV had a rather signature angled auxiliary mast which towered above the main mast. This slanting was necessary to minimize electromagnetic interference ( EMI ) among the various radars, ESM and ECM installations within or atop the main mast.
The MCV's mast can be broadly divided into two parts - the main mast and the auxiliary mast. The main mast is part of the ship structure and supports the heaviest electronic devices. Its top platform bears the rotating Ericsson Sea Giraffe 150HC air and surface search radar while the front and back facing tracking / fire-control radars are installed on lower pedestals in front of and behind the mast proper. To create even higher points for the placement of ESM and tactical communications intelligence ( TACOMINT ) antennae, the auxiliary mast is installed above the main mast from a position posterior to the search radar.
In order to minimise EMI between the various installations, the electronic experts at DSO National Laboratories determined that there was a necessity for the ESM and TACOMINT antennae to be placed concentric with the search radar's centre of rotation. Hence the naval architects engineered a customised slanted auxiliary mast with carefully calculated lengths and slant angles to place the antennae directly above the rotating radar. The auxiliary mast was constructed using materials with the desirable mechanical strength, rigidity and fatigue lifespan to hold not only these antennae and their connecting cables but also the navigation radar.
With the SLEP, much of the original mast mounted equipment have been upgraded or replaced and the legacy EMI considerations no longer existed. The auxiliary mast was therefore straightened, leading to a more normal appearance. Thus looking at the numerous MCV photos, the alignment of the auxiliary mast gives immediate information whether it was a pre or post SLEP ship.

C Band Surveillance Radar
Larger warships such as destroyers and frigates tend to have their primary surveillance radars operating at the lower frequencies of S Band or L Band for superior detection range. However these lower frequency radars require large ( and therefore heavy ) antennae in order to achieve better angular resolution. As physical size and weight are major limiting factors for many naval applications on small vessels, the C Band surveillance radar system selected for the MCV is a calculated compromise between range and resolution within the loading constrains imposed on the main mast.
The MCVs were originally equipped with the Ericsson ( now SAAB ) Sea Giraffe 150HC operating in C Band ( NATO G/H Band ) as their main air and surface search radar. It was a small, medium ranged 2D naval radar that is suitable for installation on small surface combatants. It is said to have a maximum instrumented detection range of 130km against fighter aircraft and 7km against very small, stealthy airborne targets.
With the SLEP, the corvettes had their radar system upgraded to the SAAB Sea Giraffe AMB ( Agile Multi-Beam ) which is an advanced 3D active phase array radar operating in the same G/H Band ( old IEEE nomenclature C Band ) between 5.4GHz to 5.9GHz. This multi-role, medium range surveillance radar has a high update rate and is optimised for detecting small air and surface targets, including sea-skimming missiles, in all kinds of environment including the littorals. The instrumented rage of the Sea Giraffe AMB is 180km.

The Fish
Another unique feature of the Victory-class MCV was the presence of a white ovoid structure with fins at the stern. This was the Thomson Sintra TSM 2064 variable depth sonar ( VDS ) used to detect submarines a.k.a. the Fish. It can be deployed in either active or passive listening modes and was designed to be effective for shallow littoral waters. As the name implies, the VDS can be deployed at different depths beneath the ocean to penetrate different thermal and salinity layers, something which a hull-mounted sonar cannot do.
The naval architects had already done simulations and determined that hull-mounted sonars were not compatible with the hull form and operational profile of the MCV. Fortunately the TSM 2064 is small and light enough to be installed onboard small vessels like the MCV. The Victory-class corvettes are probably among the smallest ships equipped with VDS.
Together with its triple barrel torpedo launchers, the VDS was central to the anti-submarine capability of the MCV.
Note that the Fish and the torpedo launchers were removed during the SLEP of the MCV between 2011 - 2013, taking away the ASW capabilities of the corvettes. Instead, the MCV gain a new capability in the form of the ScanEagle UAV.

Unmanned Aerial Vehicles
It might surprise you but the naval architects had made design provisions for the MCV to operate unmanned rotary aircrafts. However, those provisions were not activated as the UAV technology was not mature enough then to produce viable candidates for deployment on a small naval platform like the MCV. One hurdle was the very low reliability of the unmanned rotary system, with very short mean time between failure. Another issue was the prohibitive cost involved in implementing a then immature technology. So it wasn't until early 2009 that ship-based trials with the ScanEagle UAV were successfully conducted on the flight decks of RSN's LST and frigate. Only upon completion of the MCV's life extension program between 2011 and 2013 did we see the addition of the UAV capability to the corvettes.
The ScanEagle is a small, long endurance, low altitude UAV derived from the SeaScan UAV originally used by commercial fishermen to track schools of tuna. It has a wing-span of 3.1m, a length of 1.6m and weighs about 20kg. Its cruising speed is around 55 knots. It has a maximum range of more than 100km and an endurance of about 20 hours. Its service ceiling is about 16000ft. The UAV requires no flight deck or runway and is instead launched by a catapult and recovered by a proprietary SkyHook retrieval system.

Initially a land-based commercial off-the-shelf UAV system, even when adapted for naval use, the ScanEagle is usually deployed on the wide flight deck of large vessels such as frigates and never on smaller vessels the size of the MCV. The MCV never had a flight deck to start off with and its confined aft deck area had to support different activities including missile firing, sea boat launch and recovery, and mooring operations. Installing the ScanEagle launcher in its original configuration would have taken up too much space and would have prevented the undertaking of other deck activities. Instead, the naval engineers of the DSO National Laboratories came up with the idea of a modified launcher mounted on a customized turntable. Controlled rotation of the launcher would create an optimized UAV launch envelop while stowing it when not in use would create the necessary clearances for the firing of the Barak missiles and other deck operations. UAV operations can be conducted even under high sea state conditions as the turntable launcher is always firmly secured to the ship deck even when rotating. This innovative launch system also reduces the launch preparation time by 90% and can be operated by just a single ship crew instead of the usual three man team.

Similarly, the SkyHook arrestor system for the recovery of the UAV had also been specially modified for the MCV. It would normally occupy an area of 25m2 but was re-engineered to be extendable for recovery operations and retractable for stowage with a reduced footprint of just 10m2. Despite this, the lack of open space on the aft deck still required the modification of the ScanEagle's flight path to be at an angle to the ship during retrieval in order to minimise safety risks. The SkyHook is mounted on the starboard side of the corvette close to when the torpedo launchers once stood.
The significance of the ScanEagle UAV is that it gives the MCV a surveillance capability that is organic to the ship, thus drastically increasing the situation awareness level of the ship crew. Flying ahead of the ship, the UAV provides, among other things, live video feeds of its surroundings. The ship therefore no longer needs to solely rely on the maritime patrol aircraft or third party inputs for information on its immediate threat environment and target coordinates. The ScanEagle can instead be deployed as long as weather conditions permit. It will allow the MCV to maintain its over-the-horizon surveillance and targeting capabilities even when operating far away from its home base, out of range of any supporting MPA.
Maritime Patrol Aircraft

Airborne Early Warning Aircraft
The MCVs were also upgraded to link up with the now retired E-2C Hawkeye AEW. The APS-138 surveillance radar of the E-2C provides automatic detection and tracking of targets over water and over land up to 200 nautical miles ( 360km ) which is much further than the detection range of the mast-mounted Sea Giraffe 150HC or even the Sea Giraffe AMB air and surface search radar of the MCV. The E-2C has now been replaced by the Gulfstream G550 CAEW.
Four CIS 12.7mm ( 0.5inch ) heavy machine guns are mounted along the bridge wing to guard against small crafts, swimmers and anything that is close enough but not worth expanding a shell or missile on.
Powered by 4 MTU 16V 538 TB93 Diesels the MCV has a top speed " in excess of 30 knots " in the usually vague and non-committal MINDEF speak. It currently holds the crown for the fastest class of ship within the RSN. Only the Sea Wolf-class missile gunboat was faster but they have all been decommissioned in 2008.
When the corvette is at speed these German diesels produce a high pitch whine that is almost soothing to the ears, like a lullaby, so long as you are not in the engine room. The capability of performing high speed dashes is central to the " sprint and drift " tactic used in ASW operations but is probably most appreciated by all onboard during the return leg of an extended sea deployment. Frequently the MCV will be the first vessel type to reach home waters after the conclusion of a large scale naval exercise that involves multiple ship classes, like Exercise Starfish under the Five Power Defense Arrangement.
Harpoon Missiles
The MCV's 2 deck-mounted MK-141 quad Harpoon canister launchers pack a total of 8 RGM-84 Harpoon anti-ship missiles which are capable of hitting ships beyond the horizon, up to 70 nautical miles away. The Harpoon AShM was selected for the RSN's MGB upgrade as well as the MCV project. They are probably the RGM-84D ( Block 1C ) version which was state-of-the-art during the late eighties. It uses inertial guidance mid-course and active radar homing for terminal guidance. A direct hit by a single missile could cripple a medium sized surface combatant such as a frigate and 2 or 3 hits would probably sink it. After three decades in service, the Harpoon launchers still adorns the decks of the MCV with no plans to replace them.

Barak Missiles
The Barak missile of Israeli origin can be used against low flying aircraft and also as point defense against incoming missiles and projectiles. They are launched from 2 banks of 8-cell vertical launch unit located at the aft deck. The missile has a minimum effective range of 500m and maximum effective range of 10 - 12km. The Barak is a low cost, low maintenance air defense system and comes with its own set of fire control radar and optronic directors which can be seen mounted on the roof above the bridge of the MCV. It provides the ship with an automated, all-weather, 360 degree azimuth anti-missile capability.
The Barak system was still in development when the MCVs were commissioned in 1990 but provisions had been made by the naval architects for the installation of a hard-kill point defense system. Singapore was said to have actively participated in the joint development of the Barak system with IAI and Rafael. It was specially tailored for small ships and the RSN's unique operating environment. The Barak system was eventually acquired by the RSN in 1996 and retrofitted on all six corvettes. The first successful firing of the Barak missile by the RSN took place on 10th Sep 1997 in the South China Sea. Launched from RSS Valour, a Barak missile successfully intercepted an airborne target simulating a modern sea-skimming missile in both size and speed at a range of 6km.

Oto Melara Main Gun
The Oto Melara Super Rapid 76mm 62 caliber naval gun is probably the biggest caliber a small ship can accommodate. It is compact enough not to require too much space below deck for installation. Not surprisingly, many navies have adopted the Oto Melara 76mm in its various forms on their small vessels. The Super Rapid has a firing rate of 120 rounds per minute and is effective against air and surface targets up to 16km away. Depending on the ammunition used, it may even be effective for short range point defense against missiles. Although it has a very high rate of fire, in practice the Super Rapid is frequently fired in short burst of three rounds. On the MCV the Oto Melara is mounted on the foredeck immediately in front of the bridge and any live firing is guaranteed to be a smoky and noisy affair.

Torpedoes
Before the SLEP the corvettes had the Whitehead Alenia A244-S Mod 1 torpedo for use against submarines. These 324mm light weight torpedoes are stored and launched from two EuroTorp B515 triple tube launchers mounted on the deck of the MCV aft of the Harpoon missile canisters. They have a maximum range of 6000m and can reach a max depth of 600m, which is a lot deeper than the regional waters around Singapore. It has a maximum speed of 30 knots and has both active and passive acoustic homing capabilities. Their removal during the SLEP signaled the end of ASW operations for the MCV. This role was transferred to the Formidable-class stealth frigates, RSN next generation surface combatant.

Complement
The MCV's complement of 46 includes 7 to 8 officers - commanding officer, executive officer, operations officer, navigation officer, communications officer, weapon electronics officer, marine engineer officer and occasionally an auxiliary officer. The medical officer is not part of the ship's peacetime complement.
Since 2015 the RSN has began the deployment of reservist naval officers and ratings to fill every post on some of the MCVs. At least two teams had been created and both had achieved operational readiness status. They are held to the same high standards expected of their regular counterparts.

Longest Serving Ship Class In The RSN
Commissioned 30 years ago, the MCVs currently reign as the longest serving class of ships in the RSN. They are not the oldest vessels still in active service though. That honour probably goes to the Challenger-class submarines which were originally commissioned by the Swedish Navy in 1968 and 1969.
The Fastest Ship In The RSN
Powered by 4 MTU 16V 538 TB93 Diesels the MCV has a top speed " in excess of 30 knots " in the usually vague and non-committal MINDEF speak. It currently holds the crown for the fastest class of ship within the RSN. Only the Sea Wolf-class missile gunboat was faster but they have all been decommissioned in 2008.

Frequently the MCV will be the first vessel type to reach home waters after the conclusion of a large scale naval exercise that involves multiple ship classes, like Exercise Starfish under the Five Power Defense Arrangement.

Best Ship Award
In the past 30 years since their commissioning, the MCVs clinched a total of 16 awards in the annual Singapore Armed Forces Best Unit Competition. RSS Vigour, the winner of this year's Best Fleet Unit Award, accounted for a quarter of these with a total of four awards so far.

Ship Life Extension Program
The SLEP extends the operational lifespan of the corvettes and through the introduction of advanced surveillance, communications, as well as command and control systems, also allows them to be incorporated into the Integrated Knowledge-based Command and Control ( IKC2 ) capabilities of the third generation Singapore Armed Forces. First made public in 2009, the MCV SLEP was completed by September 2013 with RSS Valour being the final ship that was upgraded.
Though the corvettes lost their anti-submarine role with the removal of the torpedo launchers and the variable depth sonar, they gained a new capability in the form of the ScanEagle UAV. The search radar was upgraded from the Sea Giraffe 150HC to the Sea Giraffe AMB. These changes enhanced the corvette's surveillance capabilities and allowed them to " see further ".
The combat management system ( CMS ) was also revamped with a customised solution that helps the Combat Information Centre ( CIC ) team to make faster and more effective decisions. Indigenously developed by the Defense Science Technology Agency ( DSTA ) and DSO National Laboratories, the CMS has a decision support engine for data fusion, identification and threat evaluation to allow the ship crew to quickly and accurately grasp the tactical situation around the corvette. The upgraded CMS utilizes ethernet LAN instead of serial links of the legacy CMS and this broader bandwidth allows it to handle significantly more tracks and transfer data at higher speeds. It enhances the depth and the timeliness of the information presented to the ship's command team. The capabilities of this enhanced MCV CMS is said to be on par with those installed on RSN's Formidable-class stealth frigates, not at all surprising since the CMS of both ship classes are designed by the same people!

The Last Leg
If anything this article should have illustrated how much thought and detailed planning had gone into the missile corvette project from the initial conceptualization to acquisition, construction and henceforth just so that these tiny warships can achieve their greatest efficiency and always remain relevant to the Singapore Navy.
However, after 30 years of service with the RSN, the MCVs are beginning to face obsolescence even with the SLEP. Parts and components become harder to procure as time progresses and the cost of maintenance increases exponentially as the ship ages. There is also only so much that a non-stealthy old hull can be upgraded given physical and electrical limitations. Originally planned to be phased out in 2025, the COVID-19 pandemic probably brought the MCVs some reprieve as their retirement has now been postponed to 2030. This new deadline will probably represent the final extension of service as the SLEP upgrades were projected to last for a maximum of 20 years, at most. The corvettes will eventually be replaced by the multi-role combat vessel ( MRCV ), a yet-to-be-revealed design featuring stealth technology and the capability to be a mothership of sorts to airborne, surface and sub-surface unmanned platforms. Until then, the MCVs will continue to protect the vital SLOC which connects Singapore to the rest of the globe. Bravo Zulu to all from the 188 Squadron, past and present, for a job well done!
