World’s highest level fighter aircraft missile, Japan-UK collaborative research completed to completion When development realized non-US first … political decision (世界最高水準の戦闘機ミサイル、日英の共同研究完了へ 開発実現なら米以外で初…政治決断なるか)
On February 15, the government found out that it will strengthen its joint research on next-generation missile technology of fighter aircraft advanced with the UK in FY2007. It also turned out to summarize a report that the world’s highest level missiles can be developed with a combination of high technology in Japan and the UK. It is the first case outside the United States if cooperative development is realized, focusing on whether to shift to joint development or political decision.
European high speed / range range + empty detectability
“JNAAM” (joint new air to air missile = joint new air-to-air missile) is conducting joint research.
The government approved joint research at the National Security Council (NSC) in July 26. Based on the three principles of defense equipment replacement instead of the three principles of weapons export, the first case where NSC judged the possibility of collaborative research, started a joint research from November the same year.
The foundation of JNAAM is the air-to-air missile ‘Meetia’ jointly developed by six European countries such as the UK, Germany and France. It combines the technology of the same missile “AAM 4” which is mounted on the FS 15 Fighter of the Air Self Defense Force.
MiTea features an engine that maintains high speed, and the length of range is the best among missiles of the same type, but the ability to guide the target is not high. AAM 4 is equipped with radar mounted on large equipment such as naval vessels, and has excellent tracking and tracking ability of the target.
As a result of simulation assuming threats and actual scenarios, the effect of combination of technologies is large, and the performance is expected to reach world highest level.
Strengthening deterrence and handling capability is also a cost issue
If joint development is realized, fighter aircraft pilots can fire missiles farther from earlier, higher accuracy of hits. There is no need to shorten the distance from the enemy’s fighter aircraft, which also has the advantage of making it easier to avoid enemy attacks. It is expected to be installed in the state-of-the-art stealth fighter F35 which introduces 42 aircraft.
In June 28, the fighter aircraft around the Senkaku Islands (Ishigaki-shi, Okinawa Prefecture) attacked the air force fighter aircraft around the Senkaku Islands (China’s Ishigaki-shi), and in December the aircraft carrier “Liaoning” equipped with the aircraft carrier (J) It went through the Miyako Strait of the same prefecture and entered the western Pacific for the first time. If JNAAM is developed, deterrence and coping ability will be strengthened, but cost reduction is a subject.

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 to study the development of a new Joint New Air-to-Air Missile (JNAAM). MBDA UK is prime contractor on the Meteor missile which entered 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.

Will UK’s Joint Missile Project With Japan Be More Trouble Than It’s Worth?
Japan and Britain are pushing ahead with the development of a new air-to-air missile in 2017 and the technical feasibility study for the Joint New Air-to-Air Missile (JNAAM) is slated to be completed before the end of this year, Sankei News reported.
Work on the JNAAM project started in November 2014 as an attempt to merge the AESA missile seeker from the Japanese AAM-4B missile on the body of Meteor missile jointly developed by Britain, Germany and France. Even though the new missile can travel great distances, its accuracy leaves much to be desired.
The Japanese want to install an active self-homing system from their Mitsubishi AAM-4 missile, which they hope would help bring the JNAAM up to par with the very best such missiles around.
In an interview with Sputnik, political analyst Dmitry Verkhoturov said that the AAM-4B with an active radar homing system and effective range of 120 kilometers produced in Japan since 2010 is more effective than its main Chinese counterpart, the Tien Chien II, which has a passive radar and infrared homing system and a maximum range of 60 kilometers.
Even the more advanced PL-12 missile with an active homing system and a range of up to 100 kilometers is no match for Japan’s AAM-4.
“With such an edge over their Chinese rival, the Japanese have nothing to worry about,” Verkhoturov said.
As for the Meteor missile, it is equipped with an active self-homing system and has a maximum range of up to 100 kilometers.
“Even it is it is a little better than its Japanese analogue, I don’t think it makes any sense working together on a new missile that may never find any practical use,” Verkhoturov added.
According to military expert Konstantin Sivkov, “the Japanese and British are developing a new missile to leave the Americans behind. The Japanese army is well equipped, but it mainly depends on US technology, including the Aegis system, missiles and military aircraft.”
“Just like the British who scrapped their own development back in the late-1970s. Moreover, no one has so far been able to top Russia’s R-37 missile,” Sivkov said.
Dmitry Verkhoturov mentioned the KS-172 missile with an effective range of 400 kilometers, which is currently being tested in Russia. It is meant to engage strategic bombers and AWACS planes.
“This means that, compared with Russian missiles, the joint Japanese-British project is already outdated because if you increase a missile’s range from 100 kilometers to 400, you can not only shoot down enemy fighters but can also destroy the enemy’s entire battle control system and seriously degrade its air power.”
If all goes well, Japan and Britain plan to install their new missile on the fifth-generation F-35 Lightning IIs. Before this happens, however, the designers need an official go-ahead from the Japanese government. The high cost of the new missile’s development could also be a problem.
The Mitsubishi AAM-4 is a medium range air-to-air missile, it was developed by Mitsubishi Heavy Industries to succeed the aging American-made AIM-7 Sparrow. It entered service with the Japanese Air Self Defence Force in the year 1999 under the designation Type 99.
The active radar guided air-to-air missile has ECCM (Electronic Counter Countermeasure) capability, which allows it to lock on a target, even if this uses ECM, this capability results of the use of advanced semi conductor technology, which made it possible to mount a single signal processor on a small place in the missile.
The program for a new medium range missile for the Japanese Air Self Defence Force started in the year 1985, while Japan searched for a replacement for the aging AIM-7 Sparrow missile. Japan had two options, the first was developing their own low-cost, active-radar guided, medium range air-to-air missile and the second was to purchase the American AIM-120 AMRAAM; Japan decided to do both. In the year 1993 Mitsubishi Heavy Industries awarded a 15 million USD contract to develop such a missile. While the Technical Research and Development Institute (TRDI) managed the program, Mitsubishi Heavy Industries designed and developed the missile. Development finally started in the year 1993 and 50 missiles were ordered by then.

Meteor – Beyond Visual Range Air-to-Air Missile (BVRAAM)
Design of the Meteor missile system
The missile, being designed as a complete unit, requires no assembly and maintenance immediately before loading. This arrangement reduces its overall life logistic support cost.
Meteor can be launched as a stealth missile. It is equipped with enhanced kinematics features. It is capable of striking different types of targets simultaneously in almost any weather.
The Meteor has a length of 3.65m and diameter of 0.178m. It is designed to be compatible with AIM-120 type rail and eject launcher systems.
Meteor BVRAAM blast-fragmentation warhead
The Meteor missile is equipped with a blast-fragmentation warhead, supplied by TDW of Germany. The warhead is designed as a structural component of the missile. The missile integrates proximity and impact fuses.
Sensors on the beyond visual range air-to-air missile
The Meteor is equipped with a two way datalink, which allows the launch platform to provide updates on targets or re-targeting when the missile is in flight. The datalink is capable of transmitting information such as kinematic status. It also notifies target acquisition by the seeker.
The Meteor is installed with an active radar target seeker, offering high reliability in detection, tracking and classification of targets. The missile also integrates inertial measurement system (IMS) supplied by Litef.
Meteor missile performance
The missile has a range in excess of 100km. It is designed for a speed greater than Mach 4. The missile has a large no escape zone.
Propulsion system on the next generation missile
The Meteor missile is powered by a solid fuel variable flow ducted rocket (ramjet) supplied by Bayern-Chemie. The ramjet provides the Meteor missile with a capability to maintain consistent high speeds. This ability helps the missile to chase and destroy fast moving flexible targets.
The Meteor includes an electronics and propulsion control unit (EPCU). The EPCU adjusts the rocket’s air intake and duct covers based on the cruise speed and the target’s altitude.
The EPCU observes the distance and fuel level in the rocket and adjusts the throttle of the rocket. This feature of the EPCU helps the missile to manage its fuel system. Source airforce-technology.com
