Grooming Fast Jet Jockeys : Alenia Aermacchi M-346 Advanced / Lead-In Fighter Trainer



Is your country in the process of acquiring or have already acquired advanced 4++ generation multi-role combat aircraft ( MRCA ) like the Dassault Rafale or 5th generation stealth fighters like the Lockheed Martin F-35 Joint Strike Fighter? Have you wondered how the various air forces would train their pilots to fly these machines which typically cost more than a hundred million dollars each? The answer lies in a sub-class of aircraft known as the advanced jet trainer ( AJT ) and the lead-in to fighter trainer ( LIFT ). They generate far less public interest and attention than latest combat fighters but are instrumental in grooming the next generation warfighter. Today, we focus on the Alenia Aermacchi M-346 Advanced and Lead-In to Fighter Trainer, a.k.a. the Master.

Alenia Aermacchi


Alenia Aermacchi is an Italian aeronautical company whose core business is in the design and production of military trainer aircrafts. Its previous product line up includes the MB-326 basic jet trainer and the MB-339 advanced jet trainer, both of which were well regarded by their operators and had help train generations of fighter pilots. The company's latest portfolio consists of the SF-260 turboprop primary trainer, the M-345 HET high efficiency basic jet trainer and the M-346 AJT/LIFT.

Apart from trainers, other products from the company includes the C-27J Spartan, the AMX fighter ( with Embraer ), the Eurofighter Typhoon ( with Airbus and BAE ), the Panavia Tornado ( with EADS and BAE ), the F-35 ( with Lockheed Martin ), the Sukhoi Superjet 100 ( with Sukhoi ) and the ATR-42 and ATR-72 ( with Airbus ).

Types of Trainer Aircrafts



A trainer is a class of aircraft designed specifically to facilitate flight training of pilots. They are usually two-seat aircraft with either tandem or side-by-side sitting configuration and may have additional safety features not normally found in operational aircrafts like tandem flight controls. They frequently have excellent handling qualities and forgiving flight characteristics, thus allowing the trainee pilot to advance his or her skills in piloting, navigation and air combat safely and under the close supervision of the instructor.

Military flight training is expensive and demanding and is usually conducted in progressive phases to weed out unsuitable candidates. Obviously, different types of trainer aircrafts would be required for each stage.

The initial phase of the flight training where the candidate learns his first flying skills would typically be conducted with a light aircraft similar to civilian trainers like the ubiquitous, piston-engine powered Cessna 172. At the end of this stage, the trainees would be assessed as to where their attributes generally lie, fast-jets, multi-engine or rotary-wing.

The next phase is commonly known as Basic Flight Training and usually involves the use of turboprop basic or primary trainers which are obviously significantly faster and more powerful than the entry level trainers of the previous stage. Some modern turboprop basic trainers like the Pilatus PC-21 can even mimic the flight characteristics of jet trainers. Candidates eligible for fast-jets continue their training in the next phase with advanced jet trainers.

Advanced flight training for fast-jet hopefuls will now require an advanced jet trainer typically capable of high sub-sonic speeds and high energy maneuvers ( high sustained g ) complete with systems that can simulate modern sensor suites and weapon systems. While many AJTs lack radar systems, they may feature programmable multifunction displays that with inputs from data links and GPS systems can create in real time a virtual radar display. Many AJTs can also double as light attack aircraft or counter insurgency aircraft with little or no modification required. The Dassault / Dornier Alpha Jet light attack jet and advanced trainer is a good representation of this class.

The next training phase of a prospective fast-jet jockey is the Lead-In to Fighter Training. As the name implies, this is the last stage before actual deployment into combat fighters. It aims to train the pilot efficiently for all sorts of combat scenarios at a lower cost compared to direct advancement to operational conversion in a combat unit. The Lead-In Fighter Trainer is usually an advanced jet trainer with avionics that can functionally emulate combat systems found in operational fighters. Its onboard processors may be linked with ground based training systems to simulate tactical threats and self-protection functions. The M-346, one of the most sophisticated LIFT for the training of pilots for 4++ and 5th generation fighters even have design features like Hands On Throttle-And-Stick ( HOTAS ) and are Helmet Mounted Display ( HMD ) compatible.

The final stage of flight training is operational conversion and is obviously aircraft specific. The rookie pilot usually trains in a two-seat version of the aircraft type that he is destined to fly with. Operational conversion teach the pilots how to fly a particular aircraft and the best tactics to fully exploit the performance and capabilities of that aircraft. Most trainer aircrafts used for operational conversion are fully combat capable with only a slight reduction in performance compared with their single-seat peers. The F-15D for example, is the two-seat training version of the single-seat F-15C air-superiority fighter.

Note : The F-22A and the F-35 of all variants are unique in that unlike all the previous generations of US fighter aircrafts, they do not have any two-seat trainer versions. Advancement in simulator technology was deemed sufficient to negate such a requirement. That only made the lead-in to fighter training even more important.


Alenia Aermacchi M-346 Master



The M-346 is a tandem seat, sub-sonic, dual-engine military jet trainer designed for advance jet training and lead-in to fighter training for the latest 4++ generation and 5th generation fighters like the Eurofighter Typhoon and the F-35 Lightning II Joint Strike Fighter.

Finmeccanica, the parent company of Alenia Aermacchi, describes the M-346 as " the most advanced trainer aircraft on the market today and the only one specifically designed to prepare pilots for high performance new generation aircraft " and they might just be right! Below are some of the notable features of the M-346.

The aircraft was designed with the concepts of " design-to-cost " and " design-to-maintain " right from the beginning, thereby reducing acquisition costs and operational costs. The M-346 has an operational cost which is alleged to be just a tenth of the Eurofighter which Jane's estimated to be about US$18000 per flight hour. For comparison, flying a block 40/50 F-16 would cost about $7000 per hour.

The M-346 has a full authority, quadruplex digital fly-by-wire flight control system which together with an optimized aerodynamic design enables full maneuverability and controllability at very high angle of attack ( typically greater than 35 degrees ). The angle of attack and g-force limitations of the aircraft are even adjustable to suit the training syllabus.

It has a digitalized glass cockpit designed with the HOTAS philosophy and features 3 colour multifunction displays, Head-Up Display and is compatible with night vision goggles and optional helmet mounted display.

The M-346 has a pilot activated recovery system installed. When triggered, it performs automatic recovery by restoring the aircraft back to a steady and level flight path.

Powered by a pair of Honeywell F124-GA-200 low bypass turbofans, it is capable of transonic flights without the use of afterburners. Its has a vast flight envelope and together with a high thrust to weight ratio and high maneuverability enables the M-346 to offer flight handling similar to those of next generation multi-role combat aircraft. It maximizes training effectiveness and reduces the need to fly sorties on the much more expensive two-seat versions of the frontline combat aircraft, effectively prolonging their operational lifespan.

The onboard Embedded Tactical Training Simulation ( ETTS ) system allows the M-346 to emulate sensors, countermeasures and armaments. It can also interface with various munitions and equipment that are actually carried by the aircraft. The ETTS can act in a standalone mode where training data is preloaded pre-flight or in a network mode where data from a ground monitoring station is received and acted upon in real time via datalinks.

The M-346 has 9 hardpoints comprising of 2 wingtip, 6 under-wing and 1 under-fuselage pylons for carrying up to 3000kg of external loads. These may include short range air-to-air missiles like the IRIS-T or Sidewinder, Mk82/83/84 unguided bombs, precision guided munitions like GBU12 and GBU-16, AGM-65 air-to-surface missiles, anti-ship missiles, Brimstone anti-armour missiles, Durandal anti-runway dispensers, rocket pods like LAU-32 and up to 3 drop tanks on the centerline and innermost wing pylons.

The integration of a helmet mounted display system, vocal control inputs and a removable in-flight refueling probe ensures that the M-346 can carry out a complete tactical training syllabus.

Optional electronic warfare systems, self-protection systems like radar warning receivers and flare and chaff dispensers, tactical data link systems, a multimode fire control radar, radar signature reduction kits and a slew of external pods including targeting pods and gun pods enables the M-346 to be deployed in real combat operations, should the need ever arise, with excellent levels of effectiveness and good chances of survival.

The M-346 can be part of a bigger package offered by Alenia Aermacchi - the Integrated Training System ( ITS ) which includes a complete Ground Based Training System (GBTS), comprising academics, simulators, mission support system and computer-based training management system. The ITS has already been adopted by the Italian Air Force, M-346's launch customer.

Yakovlev YAK-130 : The Evil Twin?

You would have been forgiven if you thought you saw double. From the two images above, red stars aside, only the expert could tell the difference between the YAK-130 and the M-346. Yes, the M-346 has an evil twin and that's because their have a common origin.

For this, we have to return to the early post-Cold War years of the 90s, where Russia had identified the need to replace its fleet of legacy Aero Vodochody L-29 and L-39 jet trainers. At that time, five aero-design bureaus submitted proposals, but by 1991, after whittling down, the two competing finalists were the Mikoyan MiG-AT and the Yakovlev YAK-UTS.

During those halcyon times, everybody was keen to reap the dividents of the peace. Perhaps taking advantage of the new found openness of Russia and the former Soviet republics, a string of joint projects between the East and West were initiated , one of which was the cooperation agreement Aermacchi signed with Yakovlev in 1992 to provide financial and technical support for the YAK-UTS prospective trainer project. By then, the aircraft was marketed as the YAK/AEM-130.

By Sep 1993, the design of the YAK/AEM-130 was completed. First flight took place in April 1996. However, from 1998 onwards, the project took a turn for the worse and was increasingly becoming an Italian led effort after the Russians failed to provide adequate funding on their part.

In mid-2000, the partnership between Aermacchi and Yakovlev was dissolved due to their differences in priorities and the lack of funding from Russia. It was agreed that each firm would continue to develop the aircraft independently and Aermacchi would be able to sell the M-346 to NATO countries while Russia would be able market the YAK-130 to the ex-Soviet republics, India and Algeria. Yakovlev were to receive US$77million from Aermacchi for the technical documents of the aircraft.

The YAK-130 was eventually selected by the Russians as their next generation trainer in 2002, emerging victorious over the MiG-AT, mainly because it is dual role capable as both an advance trainer and a light combat aircraft. It has 9 weapons hardpoints and can carry 3000kg of external loads, exactly the same as the M-346. What's different is that this badass evil twin is designed to operate from unprepared airfields as well, and even has engine in-take blanking doors that can prevent foreign object damage. And while that has got not much to do with its effectiveness as a trainer, this enhanced capability matters greatly in combat efficiency.

Current M-346 Operators



The initial order of 15 M-346 aircrafts came from the Aeronautica Militare  ( Italian Air Force ) in 2009. They are officially given the designation T-346A by the Italian Air Force which received its first aircraft in Nov 2011. They are operated by the 212th Squadron based at Lecca-Galatina Airbase in southern Italy. IHS Jane's Defense Weekly ( 30th Mar 2016 vol 53 issue 13 ) reported that Italy had now increased its total order for the T-346A to 18. The Italians had already launched their Phase 4 LIFT programme on the T-346A since Sep 2015. For now, trainees would ultimately operationally convert to one of Italy's 3 current fighter types, the Eurofighter, the AMX or the Tornado. In the near future, the pilots will also be groomed for operational conversion to the F-35. Italy, a Tier II partner in the Joint Strike Fighter programme, has a projected requirement for a total of 90 F-35 comprising 60 conventional F-35A for the air force and 30 short take-off and vertical landing F-35B for the navy.

The first export customer was the Republic of Singapore Air Force ( RSAF ) which placed an order for 12 M-346 in Sep 2010 to replace its ageing A-4SU Super Skyhawk trainers. The first M-346 for the RSAF was rolled out in July 2012 and delivered later that year. Since then, all 12 aircrafts had been delivered and they had been inaugurated into the RSAF's 150 Squadron based in Cazaux, France. The RSAF operates a mix of 32 F-15SG and 62 F-16C/D/D+ as well as some upgraded F-5S/T fighters. Although Singapore is a Security Coorpeation Participant of the JSF programme since 2004, no decision as yet been made to acquire the F-35.

In July 2012, the Israeli Air Force ( IAF ) placed an order for 30 M-346 to replace its fleet of A-4N/H Skyhawk trainers. The first 2 M-346 for the IAF was delivered in July 2014 and all would be delivered by end 2016. The Israelis named their M-346 " Lavi " which means lion cub in Hebrew. This could prove confusing for the uninitiated as there was a failed 4+ generation fighter project by the Israel Aircraft Industries in the eighties which is also known as the IAI Lavi. The Israelis are also in the JSF programme as a Security Cooperation Participant and have a firm commitment for 100 F-35I "Adir", the first of which was delivered in Jan 2016.

In Feb 2014, the Polish Air Force placed an order for 8 M-346 to replace its 37 or so ancient PZL TS-11 jet trainers. The first 2 aircrafts would be delivered in Nov 2016. The Poles fly the F-16C/D and the MiG-29A. They are fortunately or unfortunately not in a position to contemplate any F-35 acquisition at the moment.

Update 8th Aug 2016 : In what would seem to be the biggest M-346 deal so far, Taiwan's state-owned Aerospace Industrial Development Corporation ( AIDC ) has just signed a memorandum of understanding with Leonardo, Finmeccanica's new name adopted since 28th Apr 2016 ( after this article was written ), to supply 66 M-346 advance trainers to the Republic of China Air Force ( ROCAF aka Taiwan Air Force ) to replace its ageing indigenous AT-3 trainers and probably the F-5s as well. The first 4 to 6 aircrafts will be constructed in Italy while the rest will be assembled in Taiwan, with 50% of the components imported from Italy. Technology transfer will be on the cards. The advantage that the M-346 has in Taiwan? Its Honeywell/ITEC F124 engines is in fact the non-afterburning version of the F125 that powers Taiwan's Indigenous Defense Fighter, the AIDC F-CK-1 Ching-Kuo. That makes its maintenance in Taiwan potentially a lot easier. You can read about the deal in old script Chinese here.

A significant victory for Leonardo. Now, if only the USAF could also be snared as easily.

The T-X Program : Replacing the Venerable T-38 Talon



The T-X Program is the US Air Force's ( USAF ) next generation jet trainer propramme to replace the Northrop T-38 Talon jet trainer which has been in service for more than 50 years. The T-38 is notable for being the world's first supersonic jet trainer and shares a common origin with the F-5A Freedom Fighter. Potential bidders include Lockheed Martin and KAI with their T-50A Golden Eagle offering, Northrop Grumman with BAE, L3 and Rolls Royce with an improved version of the successful Hawk T2/128, and Alenia Aermacchi partnering Raytheon with the M-346 which is re-designated the T-100 for the T-X Program. There would be an initial requirement for 350 aircrafts with a possibility of the eventual total acquisition exceeding 1000 aircrafts.

This is one competition which Alenia Aermacchi cannot afford to lose as the USAF is possibly the biggest buyer in the Free World for any military aircraft and such opportunities only present themselves once in more than half a century! Last year, Alenia Aermacchi's hope for success in the T-X Program was casted in doubt after the abrupt withdrawal of their initial US partner General Dynamics C4 Systems and new amendments in the RFI for the prospective trainer aircraft to be able to maintain a sustained load factor of at least 6.5g for a minimum of 140 continuous degrees during a 180 degree turning maneuver. Fortunately, Raytheon stepped in to take over as Alenia's American partner and prime contractor and the sustained g issue was overcome with software tweaks. The T-X Program would likely be initiated in FY2017 with a planned IOC of the selected aircraft in 2024.

Should the T-100 be selected as the T-38 replacement, it would be used to train USAF pilots for eventual deployment in the F-16, F-15, F-22 and F-35 fighters. It could also potentially be the closest thing to actually flying a Russian aircraft for these American pilots, as the T-100 / M-346 basically share the same origins with the YAK-130.

It could also mean that for the first time ever, both Russia and America could be training their elite pilots for their most advanced 4++ and 5th generation fighters like the PAK-FA and the F-22 using essentially the same aircraft, not unlike some kind of evolutionary convergence that we so frequently observe occurring in nature.


Future Developments


Apart from the American T-X Progam, what holds for the M-346 going forward? Several things immediately come to mind :

M-346 Light Attack Aircraft

Although the M-346 was not originally designed to have a dual role as a trainer and a light combat aircraft like its evil twin the YAK-130, it can easily be reconfigured to assume operational functions which can include air-to-air missions, anti-shipping and ground interdiction roles. In fact, the M-346 LCA ( Light Combat Aircraft ) option which can reportedly fire Brimstone missiles had been offered to Poland to replace its ageing Su-22 bomber. The M-346 retains a high thrust to weight ratio even under a full combat load of 3000kg. It has an impressive persistence due to its large internal fuel capacity and the ability to carry up to three 630 liter external tanks and capability of aerial refueling. It is compatible with an assortment of air-to-air and air-to-surface ordnance mounted on nine external hard points and has high maneuverability even with an engine crippled. All these characteristics make the M-346 an excellent back-up fighter especially in the " Homeland Defense " role. The M-346 LCA could be an attractive option for less affluent nations looking for a quality trainer with secondary combat capabilities at a reasonable price.

M-346 Naval

A navalised M-346 might be necessary especially if Alenia Aermacchi wins the T-X bid. Don't forget that the US Navy would also be flying the F-35 in its carrier based configuration, the F-35C, and these naval aviators would no doubt also require a lead-in fighter trainer to prepare themselves for operational conversion. The USN's current AJT is the Boeing T-45A Goshawk which has been in service for the past 25 years. They may have been adequate for preparing pilots for the Hornets and Super Hornets but would probably fall short when it comes to the JSF. The other potential client would be the French Navy who operates the Rafale M from their aircraft carrier the Charles de Gaulle. So a marinised version with a tail hook capable of catapult take-off with arrestor landings might be a future possibility.


M-346 Aggressor And Companion Trainer

Since Feb 2016, Alenia Aermacchi has been promoting the M-346 in two new roles, as a companion trainer and in dissimilar air combat training ( DACT ).

The M-346 is particularly suited to take on the role of an aggressor aircraft in DACT since the two important parameters of g force and angle of attack can be independently selected and adjusted in the flight control system enabling the M-346 to simulate the performance of various types of enemy aircrafts. Utilising the M-346 in the aggressor role can free up other high-end operation aircrafts otherwise dedicated for DACT, like those tiger-stripped F-16N ( now retired ) and F-16A at the Naval Strike and Air Warfare Center at NAS Fallon, Nevada. Not to mention that they are far more economical to fly compared to operational combat aircrafts.

In addition, further savings could be expected with networking between the ground based training system and the aircrafts involved in DACT such that a 2 on 2 training scenario that traditionally involved 4 aircrafts can be achieved with just one M-346 aggressor. The other aggressor would be flown in the simulator at the ground based training centre and would show up in the helmet mounted sights of the DACT participants in the air. Virtual aggressor!

The concept of a companion trainer is to allow pilots to fly mixed hours on their operational aircraft type and the advanced trainer and yet still maintain their combat readiness. This arrangement is obviously much more economical and at the same time extends the operational lifespan of the frontline aircraft since it would be flown less frequently. The small number of F-22A Raptors of the USAF ( only 187 built ) that are always in high demand for deployment to hotspots around the globe would probably benefit most from the adoption of such companion trainers.

dissimilar air combat training by its makers.


Training the Next Generation


The fact that the M-346 was selected as an advance trainer / lead-in fighter trainer by both the RSAF and the IAF speaks volumes for the aircraft and its designers. These two air forces are among the best in the world with very high standards and a high degree of professionalism. The M-346 would definitely be used for lead-in training for potential F-35 pilots in Israel and Italy as both have already received their first F-35I and F-35A respectively. It is probably only a matter of time before Singapore would finalise its decision to acquire the F-35 as well, and it all depends on what other regional air forces do, like Indonesia and China buying the Su-35 Super Flanker. Know that if and when that day comes, the RSAF would already have in place all the necessary expertise and training infrastructure, on the ground as well as in the air, to prepare its pilots for F-35 operational conversion.

Introduction


From the same folks who brought you the legendary Kawasaki Z-1 in 1972 that revolutionalised the motorcycle industry comes a spanking new submarine hunter? It's not surprising since Japan's Kawasaki Heavy Industries ( KHI ) is a huge industrial conglomerate made up of multiple divisions and disciplines. KHI's product portfolio includes anything from the Soryu class Submarine, bulk carriers, LNG carriers, the T-4 Advanced Jet Trainer, Boeing 787 ( Joint Production ), helicopters, space rockets and space station components, motorcycles and ATV, jet skis, high speed rail, industrial robots .... the list goes on and on. KHI is known as 川崎重工業 or Kawasaki Jukogyo in Japanese.

Maritime Patrol Aircraft : A Brief History



A maritime patrol aircraft ( MPA ) is a fixed-wing surveillance aircraft that is designed to operate over open water for extended duration in sea patrol duties, in particular anti-submarine, anti-ship and search and rescue roles. Its history can be traced as far back as World War I, when bombers and floatplanes were converted into patrol aircrafts to counter the German U-boat menace. These early generation MPAs were frequently armed with machine guns, bombs and depth charges.

The requirement for high endurance aircrafts to patrol vast expanses of oceans meant that by WWII, many MPAs were converted from long range bombers ( Consolidated B-24 Liberator ) or airliners ( Focke-Wulf Fw-200 Condor ). Some like the Consolidated PBY Catalina amphibious plane were purpose-built. The emergence of air to surface vessel radars during that era was one of the most significant technological advancement that would change the nature of naval warfare. MPAs armed with high resolution centimetric radars like the ASV III can easily detect small objects like the periscope or snorkel of a submerged submarine making them highly effective in anti-submarine warfare ( ASW ).

The immediate post-WWII period ushered in the jet era, and MPAs continued to evolve in operational capabilities with new technologies like sonobuoys and the magnetic anomaly detector ( MAD ), though due to their unique operational requirement of high loiter time at low speed and low altitude, they remained largely piston engine or turboprop driven. The Lockheed P-2V Neptune from which the Japanese variant the P-2J was based on was a typical example from that time. And yes, the P-2J was license-produced by Kawasaki.

During the Cold War, the emerging threat of ballistic missile carrying submarines raining death and destruction onto large population centres with their multiple nuclear warheads from thousands of miles away meant that MPAs continue to be relevant and in demand. Many of the MPAs currently in service throughout the world like the Lockheed P-3C Orion, the Tupolev Tu-142 Bear and the Ilyushin Il-38 May are products of that era. It was also during that time jet-powered MPAs began to appear, the first to enter service being the Hawker Siddeley Nimrod MR1.

Today, most MPAs continue the tradition of having airframes derived from proven civilian platforms, especially jetliners. The Boeing P-8A Poseidon based on the venerable 737-800 is a typical example. In the future we would undoubtedly have MPAs in the form of unmanned aerial vehicles like the soon to be operational Northrop Grumman MQ-4C Triton developed under the Broad Area Maritime Surveillance programme.


Japan's MPA Fleet


When Japan's Maritime Self-Defense Force ( JMSDF ) was formed in 1954, it operated obsolete WWII aircraft donated by the United States which included 17 Lockheed PV-2 Harpoon patrol bombers and 20 Grumman TBF Avenger torpedo bombers.

From 1956, 60 Lockheed P-2V7 Neptune MPA were added to the fleet, and starting from 1957, 60 Grumman S-2F Tracker ASW aircraft. The Japanese loved the P-2V7 so much that when the time came to have them replaced by the more advanced but expensive Lockheed P-3A Orion, they opted instead to develop an improved version, the P-2V7 Kai ( 改 - kai in Japanese means upgrade or to improve ), later licence produced and designated P-2J. A total of 83 P-2J were produced and they were operational between 1971 to 1994.

The P-2J was eventually replaced by the P-3C, 98 of which was licence produced between 1978 and 1997. Five P-3C had been converted to the OP-3C reconnaissance version and the remaining 93 P-3C are currently the backbone of the JMSDF MPA fleet. Add to that number another 5 EP-3, 1 UP-3C and 3 UP-3D, the grand total is 107 making Japan the largest P-3 operator after the United States.  They will ultimately be replaced by the P-1 of which 70 aircrafts have been planned. The JMSDF classifies the P-3C and the P-1 as Fixed Wing Patrol Aircraft (  固定翼哨戒機 Koteiyoku Shokaiki )

The Future MPA P-X Programme


Shortly after the last P-3C ( actually a UP-3D variant, see photo above ) was delivered to the JMSDF by KHI on 1st Feb 2000, marking the end of a production run that lasted for 38 years, the Japanese were already planning for its successor. The Cold War had ended and in the United States, Lockheed's next generation MPA programme, the P-7 Long Range Air ASW Capable Aircraft ( LRAACA ), failed to materialise due to budgetary problems and after incurring huge cost overruns. Existing European alternatives like the United Kingdom's Nimrod MR2 did not meet Japanese requirements. Eventually the Japanese decided that they would have to develop their own MPA.

The P-X future MPA programme was thus initiated in 2001 by the Japanese Ministry of Defence concurrently with the next generation transport aircraft C-X programme to replace the C-130 Hercules and the C-1. These two developments were to be managed as a single project and Kawasaki was appointed the main contractor. The P-X and C-X shared structural components and sub-systems and utilized commercial off the shelf products to save on development and production costs.

First flight for the P-X prototype, by then re-designated the XP-1, took place on 28th Sep 2007. By March 2010 four XP-1 had been delivered to the MOD for testing and trials. They were introduced into service in 2013 as the Kawasaki P-1 to gradually replace JMSDF's ageing P-3C Orion. They were supposed to have attained full operational capability by Sep 2015.

The P-1 is unique among all the various modern maritime patrol aircraft as it one of a few that is completely designed from the ground up and not adapted from some bomber or commercial airliner. That means every single part is purpose designed and purpose built. Also, it was originally created for just one customer, the JMSDF, since the post-war Constitution of Japan forbade the export of weapons and weapon systems until very recently. As such, throughout its development and even as it is being deployed in active service, very few outside the defense circles have heard about this mysterious Japanese multi-mission maritime aircraft.


General Characteristics


The P-1 has the appearance and size of a 90 - 100 seat regional jet. It has a length of 38m, height of 12m and a wingspan of 35.4m making it significantly bigger than the P-3C and only marginally smaller than the P-8A which it is frequently compared with. The full complement comprises of 2 flight crew and 11 mission crew. Its maximum take-off weight is 79700kg or 176000lbs. Maximum speed is said to be 996km/h ( 538 knots ) while the cruising speed is 833 km/h ( 450 knots ). The P-1's maximum range is 8000km ( 4320 nm ) and the maximum operational ceiling is 13520m ( 44200 ft ).

Fuselage and Wings


The P-1 has an aerodynamic profile most suited for low speed and low altitude flight. It has a relatively long wing span with the leading edge swept back at 25 degrees but an almost straight trailing edge. A large wing area of  170m² generates more lift, decreases stall speed and increases agility.

Part of the fuselage is made of light weight composite material like carbon fiber.  KHI is responsible for fabricating the horizontal stabilisers, Fuji Heavy Industries the main wings and the vertical stabilisers, Mitsubishi Heavy Industries the mid and rear portions of the fuselage and Sumitomo Precision Products the landing gears.


Power Plant


Unlike its turboprop powered predecessor, the P-1 is powered by four IHI F7-10 high bypass turbofan engines. Japan's IHI Corporation developed the F-7-10 specifically for the P-1, using metal alloys that are corrosion resistant in salt environments. Sound absorbing panels are also used to lower the acoustic signature of the engines, achieving a sound level 5 to 10 dB below the P-3C's Allison T-56-A-14 turboprops. The F7-10 turbofan has a bypass ratio of 8.2:1 and each delivers a maximum thrust of 60kN or 13500lbs. The jet engines enables the P-1 to achieve a greater maximum speed, a higher operating ceiling, a longer range and carry a heavier load compared with the P-3C.


Having four engines instead of two is advantageous for MPAs as they frequently fly over open bodies of water at remote locations where airfields may not be readily available for emergency landings in case of engine failure. In addition, MPAs often have to execute their combat missions at low altitudes where bird strikes can be common. A single engine failure in a twin engine MPA like the P-8A would probably have necessitated a turn around whereas an MPA with four engines could still continue its mission with one engine shutdown. If fact, P-3C jockeys are known to deliberately shut down one or two of the Orion's four turboprop engines when on-station to reduce fuel consumption and increase on-station time. The P-1 with four turbofans could supposedly do the same but it would be suicidal to try that on a P-8A.

In addition, the P-1 has a Honeywell 131-9 Auxiliary Power Unit ( APU ) installed in the fuselage forward of the horizontal stabilizer to avoid interference with the MAD apparatus in the rear.


Avionics


Unlike the mostly analogue instruments of the P-3C, the P-1 has, in common with the Kawasaki C-2 transport, a modern digital " glass cockpit " with 6 large LCD multifunction displays and 2 sets of Head-Up Displays ( HUD ). The cockpit also features huge glass windows reflecting the Japanese emphasis on low altitude visual searches.

Flight Control


You have heard of fly-by-wire where flight control of an inherently aerodynamically unstable design is achieved by onboard computers continuously micro-adjusting the control surfaces. The P-1 is a generation ahead, being the first production aircraft to feature " fly-by-light " ( FBL ) where flight control commands are transmitted via optical fibre to the actuators. This decreases the risk of electromagnetic interference with the multitude of electronic sensors onboard. FBL also has the advantage of reducing the weight of the installed wiring and reduce power consumption. The technology had been extensively tested on the UP-3C before being implemented on the P-1.


Radar


The P-1 is equipped with the HPS-106 X-Band Active Electronically Scanned Array ( AESA ) radar system jointly developed by Toshiba and the Technical Research and Development Institute ( TRDI ) of the Japanese Defence Ministry. Consisting of 4 arrays, one mounted in the nose, two side-looking panels below the cockpit area and another in the tail, the HPS-106 has a constant 360 degree coverage. It can be used in multiple modes including surface search, air search, navigational and meteorological, synthetic aperture and inverse synthetic aperture. An inverse synthetic aperture radar ( ISAR ) utilizes the motion of the target to create a high resolution 2D image that can allow for threat identification.

Electro-Optical / Infrared


The P-1 features the Fujitsu HAQ-2 EO/IR suite mounted on a ball-like turret aft of the nose cone for tracking and examining surface targets. It consists of a Forward Looking Infrared ( FLIR ) device for thermal imaging, night vision and navigation, as well as cameras for capturing images in the visible light and near-infrared spectrum.

Magnetic Anomaly Detector


The HSQ-102 magnetic anomaly detector housed in the sting-like MAD boom at the rear of the P-1 is a licence produced version of the Canadian CAE AN/ASQ-508(v) by Mitsubishi Electric. CAE is the world leader in the design, manufacture and integration of MAD systems. They have been designing MAD systems for more than 40 years and had delivered more than 2000 MAD systems to the military worldwide. The AN/ASQ-508(v) is also known as the Advanced Integrated MAD System ( AIMS ) and consists of a highly sensitive magnetometer with associated electronics mounted in the tail area of an aircraft to minimize magnetic interference. It detects the variations in the earth's magnetic field caused by the presence of metallic objects in the vicinity like a submerged submarine. The detection range is in the region of 1200m, meaning the MAD will work best with the aircraft flying at low altitudes and at low speeds, both of which the P-1 excels in. One of the key differences between the P-1 and the P-8 is that the P-8 does not have a MAD system.

Acoustic System and Sonobuoys


The P-1 can carry 30 pre-loaded sonobuoys and another 60 in racks in the cabin for reloading. The Acoustic Processor HQA-7 is manufactured by NEC. Other components of the acoustic system includes the  HRQ-1 Sonobuoy Receiver, HQH-106 Acoustic Data Recorder and the HAS-107 Sonobuoy Controller.

Command and Control


The P-1 has a Combat Command System designated the HYQ-3 by Toshiba which is basically an onboard combat information processor, some sort of artificial intelligence that can assist the mission commander in planning for the best respond to an encountered threat, like delivering the optimal firing solution on an enemy submarine based on the combined information collected by all the plane's sensors and sensors from other friendly platforms nearby.

 

Communications


The P-1 is fitted with the HRC-124 UHF/VHF Radio and the HRC-123 satellite communications equipment made by Mitsubishi Electric.


Tactical Data Link


Equipped with Link 16 compatible MIDS-LVT terminal, the P-1 can share targeting and any other information with similarly equipped aircrafts like the F-15J, P-3C, E-767 AWACS, E-2C AEW, MH-60 naval helicopters, F-35 JSF, and surface vessels like the JMSDF's Aegis destroyers.


IFF


The HPX-105 Identification Friend or Foe system is installed with the two sets of four N-AT-347 IFF antennae mounted in front of the cockpit wind screen and at the under-fuselage area.

Armaments


The P-1 has a total of 8 hard points under its wings which can be used to carry air to surface missiles like the AGM-84 Harpoon, the AGM-65 Maverick and the indigenously developed ASM-1C. These pylons, also known as the BRU-47/A Bomb Release Unit are rated to carry up to 2000lbs of ordnance each.

It also has an internal bomb bay with an additional 8 hard points which can be loaded with bombs, mines, depth charges and light weight torpedoes including the Mk46, the Japanese Type 97 ( G-RX4 ) and the latest Type 12 ( G-RX5 ). Up to 9000kg or 20000lbs of ordnance could be carried.

Self-Protection System 


The P-1 is equipped with the Mitsubishi Electric HLQ-9 self-protection suite which includes the missile approach warning system ( MAWS ) and the radar warning receiver ( RWR ), accompanied by the usual dispensers for flare and chaff.

An Electronic Support Measures ( ESM ) suite, the Mitsubishi Electric HLR-109B is installed. You can see the ESM flaring which is the prominent bulge on top of the fuselage slightly behind the cockpit. The ESM suite detects and classifies enemy radar emissions and gives the P-1 a secondary role as an  Intelligence, Surveillance and Reconnaissance ( ISR ) platform.

Air-to-Air Refueling


All indications seem to point towards the fact that unlike the Boeing P-8A or the Kawasaki C-2 with which it shares some common components, the P-1 does not have a probe or receptacle for accepting fuel transfers midair. It is highly unlikely that the meticulous Japanese designers would have overlooked this feature. Most probably it was intentionally omitted as a cost saving move. Further more, with a range of 8000km, perhaps the JMSDF chose to live without air-to-air refueling.


P-1 Variants


Just like its predecessor the P-3C Orion which had spawned many variants to serve different combat missions, the P-1 can potentially be similarly modified into different hardware configurations :

UP-1 : Utility / multi-purpose aircraft that can be used as a test bed for systems and equipment or in a supportive role as a training platform.

EP-1 : Signals Intelligence ( SIGINT ), Electronic Intelligence ( ELINT ) platform.

OP-1 : Observation / Visual Imaging platform.

AEW :  To replace the ageing E-2C Hawkeye airborne early warning aircraft. But the US had just approved the sale of four E-2D to Japan last year, so AEW conversion is currently less urgent or likely.

AIRBOSS : As an Advanced InfraRed Ballistic Missile Observation Sensor System platform. Obviously with Dear Leader as one's neighbour, the capability to detect ICBM / IRBM / SLBM launches in a timely manner can be a matter of utmost importance.

In Jun 2015, the first XP-1 prototype number 5501 had been converted to the UP-1 configuration with the aircraft number correspondingly reassigned 9501.

Numbers Ordered


Based on Japanese Defence Ministry annual budget reports of the past few years, these are the current number of P-1 ordered and on order.

FY2008  4   units  ¥ 67.9billion
FY2010  1   unit    ¥ 21.1billion
FY2011  3   units  ¥ 54.4billion
FY2013  2   units  ¥ 40.9billion
FY2014  3   units  ¥ 59.4billion
FY2015  20 units  ¥ 350.4billion

Total P-1 ordered so far is 33 aircrafts, excluding the four XP-1 prototypes. The first 13 units from FY2008 to FY2014 are probably the low rate initial production ( LRIP ) tranches. Mass production really starts with FY2015's 20 unit order. All operational P-1s are deployed at Atsugi Air Base in Kanagawa Prefecture.



Exporting the P-1



Japanese weapon systems have traditionally been expensive due to the fact that they cannot be exported and so production runs are relatively small and cater to only the local defense agencies. Economy of scale can hardly be achieved with a such a small captive market. That has changed since last year when Prime Minister Abe tweaked the Constitution, paving the way for future weapon exports. And Kawasaki has been hard at work trying to sell the P-1 overseas.

Among the potential clients was the United Kingdom, a maritime nation whom in 2010 foolishly retired its Nimrod MR2 MPAs and then abruptly cancelled its replacement, the MRA.4 who's development was by then almost near completion, leaving them with absolutely no MPAs. In July 2015, the P-1 made its first overseas public appearance at the Royal International Air Tattoo ( RIAT ) at RAF Fairford, Gloucestershire, England, in an attempt to generate British interest in the aircraft. If successful, the deal could advance defence co-operation between the two countries and could be worth up to one billion dollars. Two aircrafts flew over to Fairford, number 5504 and 5507, one for static display and one for flight demonstration. You can watch and hear the flight demo here. After the airshow the P-1 went on to Djibouti to carry out hot weather tests before returning to Atsugi Air Base. The P-1's appearance at RIAT was well received and brought the exposure and generated the awareness it needed to compete successfully on the international stage. Hopefully we can begin to see the P-1 at more international airshows in the near future. Unfortunately for the Japanese, on 23rd Nov 2015 the UK announced their intention to buy nine P-8A Poseidon as part of the Strategic Defence and Security Review 2015, without going through any tender or competition.

However, apart from the UK, there are many other navies worldwide that operate the ageing P-3C Orion and they would soon need a replacement. So Kawasaki should in theory have no shortage of potential clients. The main competition would be the Boeing P-8A as they both have very similar capabilities, not surprising as they were intended to be replacements for the same aircraft. Already, Australia, a major P-3C ( AP-3C ) operator has selected the P-8A as its next generation MPA at a cost of A$4 billion for a total of 8 planes with support facilities. So has India, which will operate the P-8I. Still, at an estimated US$250 million per plane, the P-8A is significantly more expensive than the P-1 which costs half as much at $150 million ( based on Japanese MOD figures, FY 2015 acquisition of 20 P-1 at ¥350.4billion ). This would make the P-1 a value buy for current P-3C operators as well as any MPA operator looking to renew their fleet.



P-1 for Singapore?


Why not? The Republic of Singapore Air Force ( RSAF ) currently operates a fleet of 5 Fokker F-50 Enforcer II MPAs. These aircrafts have been in service since 1994 and are close to their end-of-life. Upgrading these MPAs would be challenging as the maker, Dutch aviation company Fokker had gone into receivership in 1996 and is now defunct. RSAF had apparently requested to inspect ex-USN P-3Cs in storage in Dec 2010 which meant it was considering the refurbished Orion as replacement for the F-50. Now, five years on, the P-1 has completed its development and has emerged a viable option since it is technically more advanced than the venerable P-3C and is a whole lot cheaper than the P-8A whose capability it mostly matches.

How much cheaper is it to restore a mothballed P-3C to active duty with modernized avionics and 15000 hours of life extension compared to buying a new build P-1 is anybody's guess, but I'll pick the a P-1 over the P-3 anytime.


P-1 and the State of the Japanese Defence Industry



For the past 70 years, the Japanese defence industry had lead a frustrating existence where restricted by the Constitution, their quality products were procured in anaemic quantities only for the domestic market. This dated, self-imposed restriction had finally been lifted paving the way for major arms export. Already, we are seeing Japanese defence companies participating in international trade shows for the first time.

The Kawasaki P-1 is a highly capable maritime patrol aircraft and a worthy successor to the P-3C. Its success in Japan had probably been guaranteed even before the maiden flight of the first prototype. Currently the planned procurement is for 70 aircrafts to replace 107 P-3C of all variants. Funding for the first 33 P-1 had already been disbursed / approved. The next logical milestone would be to secure export customers so that production volume can be ramped up further and unit cost can come down. Together with the AIP capable Soryu class submarine, and the ShinMaywa US-2 amphibious search and rescue plane, the P-1 maritime patrol aircraft would spearhead the Japanese effort to break into the international arms market. There would hopefully be some successes soon.
