Mitsubishi F-2 – Japan

The Mitsubishi F-2 is a multirole fighter manufactured by Mitsubishi Heavy Industries (MHI) and Lockheed Martin for the Japan Air Self-Defense Force, with a 60/40 split in manufacturing between Japan and the USA. Production started in 1996 and the first aircraft entered service in 2000. The first 76 aircraft entered service in 2008, with a total of 94 airframes produced. The first AESA Active electronically scanned array radar on a combat aircraft was the J/APG-1 introduced on the Mitsubishi F-2 in 1995. Source @wikiwand.com

J/APG-1 is an Active electronically scanned array radar system designed and manufactured by Mitsubishi Electric for use on the Mitsubishi F-2 fighter aircraft. It was the first series production AESA to be introduced on a military aircraft in service. It is currently being upgraded to the J/APG-2 standard for compatibility with the new AAM-4B air-to-air missile. Source @america.pink

It seems from Chinese source that the stated 800 T/R modules on the J/APG-1 AESA has been purposely understated as the actual T/R module is more likely to be 1216.

Japan Upgrading 60 F-2s With AAM-4, J/APG-2

Japan already has bought Raytheon AIM-120 Amraams, so why is it spending ¥36 billion ($468 million) to upgrade about 60 F-2 fighters with the Mitsubishi Electric Corp. AAM-4B missile?

Although the benefits to Japanese industry are obvious, details of the upgrade and the missile itself suggest that the program is giving an enormous boost to the Mitsubishi Heavy Industries fighter’s ability to counter enemy aircraft. The weapon has at least one advanced feature that other such missiles lack: a seeker with an active, electronically scanned array (AESA) radar.

The program will move into high gear in the financial year that begins April 1. The work is progressing in two parallel programs: integration of the AAM-4B missile, and upgrade of the J/APG-1 radar to a more powerful standard called J/APG-2. The improved radar, needed to exploit the new missile, will incidentally raise the capabilities of the aircraft by offering greater detection ranges.

The F-2 support fighter aircraft is a multi role single engine fighter aircraft principally designed for the Japan Air Self Defence Force (JASDF), the result of a joint Japan and USA development programme. Mitsubishi Heavy Industries (MHI) is the prime contractor and Lockheed Martin Aeronautics Company serves as the principal US subcontractor. The F-2A is the single-seat version and F-2B is the two-seat version.

The Japanese Defence Agency originally planned to procure a total of 130 F-2 aircraft (83 single-seat and 47 two-seat aircraft) with deliveries to beyond 2010, but, in early 2007, this number was reduced to 94.

The initial order was for 81 aircraft. A further five were ordered in March 2007 in a $150m contract. MHI awarded a further $250m contract to Lockheed Martin in April 2008 to manufacture components for eight more F-2 aircraft. The contract was the 12th annual contract awarded by MHI to Lockheed Martin.

F-2 and F-16 compared

Some differences in the F-2 from the F-16A:

  • a 25% larger wing area
  • composite materials used to reduce overall weight and radar signature
  • longer and wider nose to accommodate a J/APG-1/J/APG-2 active electronically scanned array (AESA) radar. The F-2 was the first operational military aircraft in the world to feature an AESA radar, before the F-22 Raptor’s AN/APG-77 AESA radar.
  • larger tailplane
  • larger air intake
  • three-piece cockpit canopy
  • capabilities for four ASM-1 or ASM-2 anti-ship missiles, four AAMs, and additional fuel tanks 

Also, the F-2 is equipped with a drogue parachute, like the version of the F-16 used by Korea, Netherlands,Norway, Greece, Turkey, Indonesia, Taiwan, and Venezuela. Source @wikiwand.com

F-2 fighter programme and development

The FS-X program

The FS-X’s origins can be traced back to the early 1980’s and the highly secretive Laboratory Three division of Japan’s Technical Research and Development Institute (TRDI). There, studies were being carried out to investigate the options for an indigenous design, combining long range with maneuverability, to meet the particular requirements of the Japanese Air Self-Defense Force (JASDF).

In 1987, the JASDF selected a variant of the F-16C as the Japanese FS-X aircraft to replace the Mitsubishi F-1 aircraft, and in 1988 Mitsubishi was selected as prime contractor for the aircraft, which became known as the F-2. The programme involved technology transfer from the USA to Japan, and responsibility for cost sharing was split 60% by Japan and 40% by USA.

Four flying prototypes were developed, along with two static prototypes for static testing and for fatigue tests. Flight trials of the prototypes were successfully completed by 1997, and the aircraft entered production in 1998.

The first production aircraft was delivered to the Japanese Defence Agency in by March 2005 61 F-2 fighters had been delivered. The aircraft are being assembled at Mitsubishi’s Komaki South Plant in Nagoya. MHI expects to complete deliveries of 76 aircraft in the near future.


In June 2007, the F-2 made its first overseas deployment to Andersen AFB in Guam for joint US / Japan exercises. The F-2 dropped live weapons for the first time during the exercises.

F-2 fighter design

An important element in the specification of the F-2 was its ability to carry four ASM-1 or ASM-2 anti shipping missiles. This requirement dictated the need for the larger wing area and consequent changes. Although the F-2 is placed on interception duties as other fighter types in JASDF, it’s main role is considered to be the destruction of enemy landing forces or enemy warships with these missles. The role is evident from the F-2’s dark blue camo scheme, which is so different from other fighter types in JASDF. Source @f-16.net/f-16

ASM-1 Type 80 anti-shipping missile

The Japanese Type 80 ASM-1 Missile is designed primarily as an air-launched coastal defense weapon. In practice it could be used against a variety of surface targets, including ships, truck convoys, light armored vehicles, buildings and bridges. With the addition of a solid-fuel booster stage, this missile is also used as part of the ground-launched SSM-1 system.

Based on the Type-80 Air-to-Ship Missile, various anti-ship systems including Type-88 SSM (Surface-to-Ship Missile), Type-90 SSM (Ship-to-Ship Missile), Type-91 and 93 ASMs (Air-to-Ship Missile) have been developed. These systems comprise the Japanese anti-ship missile family and are deployed in the Ground, Maritime, and Air Self Defense Forces.

Structure & Avionics

The FS-X is quite similar in appearance to the F-16, but structural modifications include:

  • Japanese-designed co-cured composite wing of greater span (1.7m wider) and root chord, with slightly less leading edge sweep. The composites give the wing added strength while reducing the weight;
  • increased span tailplane;
  • slightly reshaped and enlarged radome and forward fuselage (fuselage length has increased by 0.5m);
  • slightly altered Leading-Edge Root Extensions (LERX).

Increased span tailplan

Slightly altered Leading-Edge Root Extensions (LERX)

Overall, the FS-X is substantially larger than the F-16, resulting in a maximum take-off weight of 49,000lb, compared to the F-16C’s 42,000lb, although both are powered by the same 129kN (29,000lb)-thrust General Electric F110-129 turbofan engine. Other FSX structural-design changes include radar-absorbent material (RAM) applied to the aircraft’s nose, wing leading-edges and engine inlet, the use of titanium in the tail and fuselage, the addition of a braking parachute and a two-piece canopy reinforced against large bird strikes.

The primary difference, although less conspicuous than the structural modifications, between the FS-X and the F-16 is in the use of Japanese domestic technology for much of the avionics, including:

  • a new Mitsubishi Electric (Melco)-designed active phased-array radar comprising 800 3W gallium-arsenide transmit/receive modules;
  • Yokogawa LCD multi-function display (MFD);
  • Shimadzu holographic head-up display (HUD);
  • internal Mitsubishi Electric integrated electronic warfare system;
  • Japan Aviation Electronics laser inertial-navigation system backed-up with four conventional gyros;

Japan has also been forced to develop its own fly-by-wire software by the US Government’s refusal to release the F-16s computer source codes. The FS-X’s software is based on MHI’s control-configured vehicle (CCV) research program flown in the early 1980’s using a modified Mitsubishi T-2 trainer. Source @f-16.net

Kawasaki is responsible for the construction of the midsection of the fuselage, and also the doors to the main wheel and the engine. Mitsubishi builds the forward section of the fuselage and the wings.

Mitsubishi has also designed the lower-wing box structure, which includes lower skin, spars, ribs and cap, and is made from graphite-epoxy composite and co-cured together in an autoclave. This is the first application of co-cured technology to a production tactical fighter.

Fuji manufactures the upper-wing surface skin, the wing fairings, the radome, flaperons and the engine air-intake units and the tail section. Lockheed Martin Aeronautics Company supplies the rear section of the fuselage, the port-side wing boxes and the leading-edge flaps.

Integrated weapons system

The aircraft’s integrated electronic warfare system, mission computer and active phased array radar were developed by Mitsubishi Electric.

An M61A1 Vulcan 20mm multi-barrel gun is installed in the wing root of the port wing. There are 13 hardpoints for carrying weapon systems and stores: one on the fuselage centreline, one on each wing-tip and five under each wing. The stores management system is supplied by Lockheed Martin.

Japan’s F-2 Marks 8th Platform to Fly with Lockheed Martin Sniper Advanced Targeting Pod

Sniper Pod

Sniper pods provide improved long-range target detection/identification and continuous stabilized surveillance for all missions, including close air support of ground forces. The Sniper pod enables aircrews to detect and identify weapon caches and individuals carrying armaments, all outside jet noise ranges. Superior imagery, a video datalink and J-series-weapons-quality coordinates provided by the Sniper pod enable rapid target decisions and keep aircrews out of threat ranges.

High resolution imagery for non-traditional intelligence, surveillance and reconnaissance (NTISR) enables the Sniper pod to play a major role in Air Force operations in theater, providing top cover for ground forces, as well as increasing the safety of civilian populations.

The Sniper pod is combat proven on U.S. Air Force and international F-15E, F-16 (all blocks), B-1, A-10C, Harrier GR7/9 and CF-18 aircraft. Lockheed Martin is also in the final stages of integrating the Sniper pod on the B-52. The pod’s plug-and-play capability facilitates moving the pod across platforms without changing software.

Sniper pods include a high definition mid-wave forward looking infrared (FLIR), dual-mode laser, HDTV, laser spot tracker, laser marker, video data link, and a digital data recorder. Advanced image processing algorithms, combined with rock steady stabilization techniques, provide cutting-edge performance. The pod features automatic tracking and laser designation of tactical size targets via real-time imagery presented on cockpit displays. The Sniper pod is fully compatible with the latest J-series munitions for precision weapons delivery against multiple moving and fixed targets.


Advanced Targeting Pod – Sensor Enhancement (ATP-SE) design upgrades include enhanced sensors, advanced processors, and automated NTISR modes.

The Sniper pod’s architecture and modular design permits true two-level maintenance, eliminating costly intermediate-level support. Automated built-in test permits flightline maintainers to isolate and replace an LRU in under 20 minutes. Spares are ordered through a user-friendly website offering in-transit visibility to parts shipment.

The Sniper pod’s modular design also offers an affordable road map for modernizing and enhancing precision targeting capabilities for U.S. Air Force and coalition partner aircraft.

M61 A1 Vulcan 20mm



The General Electric M61A1 Vulcan is a 6-barrel 20mm cannon of the gatling-type. It fires standard M50 ammunition at 6,000 rounds per minute (rate selectable in certain installations).

The multiple-barrels cannon offers both advantages in firing rate and in barrel life. As the 6 barrels revolve, they proceed through the different stages of the gun firing cycle. Each barrel is fired as it passes through the top position, after which the spent case is extracted and ejected, and a new round is fed and chambered – all at different positions on the circle described by the revolving barrel. This means that the firing rate is multiplied by the number of barrels, as six barrels are being loaded in parallel. Furthermore, since each barrel is only fired at 1/6th of the total firing rate, barrel wear and tear is not increased. Major drawback is that ammunition is consumed at a vast rate, requiring large ammo magazines.

The gun is fed through long linked belts of ammo, and although the gun appeared from early on in the development to be extremely reliable, the unprecedented rate of fire caused severe problems with these belts. The links connection the rounds often bent, broke or stretched, causing the gun to jam. Furthermore, provisions had to be made to dispose of the links. As a result, development of a new linkless feed system quickly started. Inside the drum, the rounds (tips to the middle) are placed in a giant Archimedean screw which moves them into the conveyor belt feeding the gun. In the F-16 and some other installations (M61A1 installations are tailor-made to each aircraft type), the empty case is transported back to the drum via a second conveyor belt. Both conveyor belts are housed in strong flexible ducts, and are powered by the gun, as well as the screw inside the drum which is driven via a high-power flexible coupling.

Image @f-16.net

Most members of the M61A1 family are driven by the aircraft’s hydraulic system, or (exceptionally) by the electrical power system. 35hp is needed to drive the gun at full firing rate, and barrels rotate anticlockwise when viewed in the direction of firing. The stationary breech housing has a deep elliptical slot in its inner wall in which run 6 cam followers, on the breech of each barrel. The followers are driven linearly in and out of the associated breech, successively chambering, firing and extracting the rounds. The breech rotor, to which are attached the 6 barrels, revolves inside the breech housing.

At the muzzle end, the 6 barrels are fitted in a clamp. This clamp can be replaced by other models, thereby offering a means to vary the barrel angles and create slightly different dispersion patterns. The inside of each barrel is provided with a twisted groove to give the rounds a spinning motion.

There are two Frazer Nash common rail launchers manufactured by Nippi. The aircraft is capable of deploying the Raytheon AIM-7F/M medium-range Sparrow air-to-air missile, the Raytheon AIM-9L short-range Sidewinder and the Mitsubishi Heavy Industries AAM-3 short-range air-to-air missile.

AIM-7F/M medium-range Sparrow air-to-air missile


The AIM-7 Sparrow is a radar-guided, air-to-air missile with a high-explosive warhead. The versatile Sparrow has all-weather, all-altitude operational capability and can attack high-performance aircraft and missiles from any direction. The AIM/RIM-7 series is a semiactive, air-to-air, boost-glide missile, designed to be either rail or ejection launched. Semiactive, continuous wave, homing radar, and hydraulically-operated control surfaces direct and stabilize the missile on a proportional navigational course to the target. Propulsion for the missile is provided by a solid propellant rocket motor.

Guidance Section. The Guidance Section is a solid-state design. The Guidance Section is constructed modularly and includes a radome, tunnel cable to the control section, forward antenna, target and rear receivers, an embedded Missile Borne Computer (MBC), a radar fuze unit, and electric gimbaled motors.
Control Section. The control section consists of an autopilot and a hydraulic control group which provide wing control to guide the missile to the target and to stabilize the missile. An accumulator supplies the hydraulic power to move the wings in response to guidance command signals from the autopilot. In addition to circuits for processing guidance and stabilization signals, the control section also contains an AC/DC converter for adapting external power for missile requirements before launch.


The Sparrow missile is a supersonic, medium-range, aerial-intercept missile that guides on Radio Frequency (RF) energy. Sparrow incorporates Electronic Counter-Countermeasure (ECCM) capabilities, also known as Electronic Protection (EP), to defeat countermeasures such as jamming. The Sparrow began as project Hotshot in 1946, and became operational in late 1953. Experience during the Vietnam war demonstrated it to be virtually useless against manuvering targets. A special AIM-7E-2 dogfight version was produced to overcome these shortcomings. Current configurations of the Sparrow missile include four air-launched variants, AIM-7M F1 Build, AIM-7M H Build, AIM-7P Block I, and AIM-7P Block II, and as many ship-launched variants, RIM-7M F1 Build, RIM-7M H Build, RIM-7P Block I, and RIM-7P Block II.



The AIM-7F joined the Air Force inventory in 1976 as the primary medium-range, air-to-air missile for the F-15 Eagle. The AIM-7F was an almost completely new missile, gaining ability from improved avionics that allowed the warhead to be moved to the front, allowing a bigger motor to be carried that has improved range.



The AIM-7M, the only current operational version, entered service in 1982. It has improved reliability and performance over earlier models at low altitudes and in electronic countermeasures environments. It also has a significantly more lethal warhead. The latest software version of the AIM-7M is the H-Build, which has been produced since 1987 and incorporates additional improvements in guidance. AIM/RIM-7M DT and OT was successfully completed in FY82. The F-15 Eagle and F-16 Fighting Falcon fighters carry the AIM-7M Sparrow.

AIM-9L short-range Sidewindermain1

The AIM-9 Sidewinder is a supersonic, heat-seeking, air-to-air missile carried by fighter aircraft. It has a high-explosive warhead and an active infrared guidance system. The Sidewinder was developed by the US Navy for fleet air defense and was adapted by the U.S. Air Force for fighter aircraft use. Early versions of the missile were extensively used in the Southeast Asian conflict.

The missile’s main components are an infrared homing guidance section, an active optical target detector, a high-explosive warhead, and a rocket motor.

AIM-9L Variant


The AIM-9L added a more powerful solid-propellant rocket motor as well as tracking maneuvering ability. Improvements in heat sensor and control systems have provided the AIM-9L missile with an all-aspect attack capability and improved guidance characteristics. The L model was the first Sidewinder with the ability to attack from all angles, including head-on. An improved active optical fuze increased the missile’s lethality and resistance to electronic countermeasures. A conical scan seeker increased seeker sensitivity and improved tracking stability. The AIM-9L is configured with an annular blast fragmentation warhead. Production and delivery of the AIM-9L began in 1976.

AAM-3 short-range air-to-air missile

The history of air-to-air missile [AAM] R&D in Japan started in 1955. The missiles are called the AAM-1, 2, and 3, the order in which they were developed. Japan has completed the development of the Type 90 AAM (AAM-3) with an improved turning performance, infrared counter-counter measures (IRCCM) capability and off-boresight capability. The AAM -3 is expected to replace the American Sidewinders, and the GSDF already fields the AAM-3. At present, research into SRMs is continuing to improve the off-boresight and IRCCM capabilities to deal with future threats. Data @fas.org

General characteristics



Mitsubishi AAM-4

The Mitsubishi AAM-4 (Type 99 air-to-air missile, 99式空対空誘導弾 (99 Shiki Kūtaikū Yūdōdan?)) is a medium-range active radar homing air-to-air missile, considered as modern beyond-visual-range air-to-air missile developed in Japan and intended to replace the semi-active radar homing AIM-7 Sparrow missile in service. It has been operational since 1999.

The improved AAM-4B was the world’s first air-to-air missile with an AESA radar seeker. The AAM-4B entered production in 2010 for service on the F-15J and F-2, but it is too large to be carried in the weapons bay of the F-35 Lightning II. So on 17 July 2014 Japan announced a collaboration with the United Kingdom[2]to study the development of a new Joint New Air-to-Air Missile (JNAAM). MBDA UK is prime contractor on the Meteor missile which will enter service on the Saab JAS 39 Gripen in 2016 and on the Eurofighter Typhoon and Dassault Rafale in 2018,and can fit in the internal weapons bay of the F-35. It has a unique variable-flow ramjet motor that according to MBDA gives the Meteor the largest no-escape zone of any air-to-air missile. The JNAAM will “[combine] the UK’s missile-related technologies and Japanese seeker technologies”, possibly with some adjustments to help the missile fit better in the F-35 weapons bay.

Mitsubishi AAM-5

AAM-5The Mitsubishi AAM-5 (Type 04 air-to-air missile, 04式空対空誘導弾) is a short-range air-to-air missile developed and produced by Mitsubishi Heavy Industries for the Japan Air Self-Defense Force. Development of the missile as a replacement for the AAM-3 (Type 90) missile commenced in 1991 and it has been operational since 2004.

Unlike the Type 90 guided missile, the AAM-5 does not have a cannode. Instead, flight is controlled by a thrust vector controlled rocket motor and free-moving type control wings on the missile’s tail, which provides high mobility. The central portion of the missile has a long, thin strakes.
