Research of the Future Medium Range Air to Air Missile

In this research, by utilising state-of-the-art radar seeker*1 technologies, we will establish the technologies for miniaturised and high-performance seekers applicable to various kinds of missiles, including medium range air to air missiles equipped in weapon bay of the fighter aircraft.
 Also, we will validate the compatibility between the miniaturised and high-performance seeker with the ducted rocket engine*2, one of the best options of propulsion devices for the future medium range air to air missiles. This research is conducted as the cooperative research with UK by using Meteor*3 components applied practically in European nations.

*1 Seeker:the missile component to detect, identify and track the target
*2 Ducted rocket engine : High-speed and long-range propulsion device
*3 Meteor:Medium range air to air missiles developed by European nations


In recent years, countries around Japan have a tendency to increase the number of surface ships. In response to the attack on island, by improving the ability to deal with enemy surface ships, the sea superiority is acquired and maintained. The TYPE 12 SURFACE TO SHIP MISSILE KAI and the NEW AIR TO SHIP MISSILE FOR MARITIME PATROL AIRCRAFT will be developed with improved function and performance.


Countries around Japan are improving their landing capability quantitatively and qualitatively. As a response to the attack on the island, the function and performance such as range extension, ability to shoot many targets at the same time, ability to shoot at high speed targets, ability to shoot with all rounds, etc. is improved and acquisition cost is reduced. For that purpose, MULTI-PURPOSE MISSILE SYSTEM KAI will be developed.

New ship to air missile

In order to strengthen the air defense capabilities of DD, we develop a long range ship to air missile that can cope with target aircraft etc.

Research on element technologies of a HVGP(Hyper Velocity Gliding Projectile) intended for the defense of remote islands

HVGP intended for the defense of remote islands can glide at high velocity and attack a target in order to enable island-to-island firing. Use the block method in the research on element technologies of a hyper velocity glide missile intended for the defense of remote islands, which began in FY2018, to promptly apply research results to equipment, and make them operational sequentially.

Products After Development

Type-03 Medium-Range Surface-to-Air Missile(Improved)

Type-03 Medium-Range Surface-to-Air Missile(Improved) is deployed with the JGSDF Anti-aircraft Artillery Group, which uses improved targeting of cruise and anti-surface missile threats and networking features for better range, while reduces acquisition cost.


ASM-3 has capability to more effectively defeat enemy combat vessels with high performance anti-air firearms.

The Standard Missile-3 Block IIA Cooperative Development (SCD) Project between Japan and the U.S.

The SCD Project was started in 2006 to develop the next generation SM-3 missile. This cooperative development program fully established new technology, the SM-3 Block IIA missile, and was completed with successful intercepts of ballistic targets using an AEGIS Destroyer and an AEGIS Ashore Site as shooting platforms in October and December of 2018. As a key element for the Integrated Missile Defense of Japan, the SM-3 Block IIA will be deployed on AEGIS ships and AEGIS Ashore sites.

New Surface-to-Surface Missile

The Division is developing a new surface-to-surface guided missile that is launched from a naval platform against enemy surface vessels, etc. It is designed with an extended range, improved guidance accuracy, etc. compared to the current type 90 surface-to-surface missile (SSM-1B).


AAM-5B features extended IR seeker cooling time, improved capability of counter infrared jamming and improved identification capability between target and background led by the improved guidance system.
