US and Japan Agree to Build Joint AMRAAM Missile Production Facility in Japan

The US and Japan will jointly produce advanced air-to-air missiles at a new facility in Japan, deepening their defense alliance.

The United States and Japan have agreed to establish a facility on Japanese soil for the joint production of Advanced Medium-Range Air-to-Air Missiles (AMRAAMs), Japan's defense chief announced on Wednesday. The agreement marks a significant step in defense-industrial cooperation between the two allies, moving beyond technology-sharing into co-manufacturing of a frontline weapons system used by air forces across NATO and allied nations. The announcement is the latest in a series of moves by Washington and Tokyo to tighten their security partnership, as both governments have publicly emphasized the need to strengthen deterrence in the Indo-Pacific region. Joint production arrangements of this kind allow both countries to build up stockpiles more quickly and reduce dependence on single-country supply chains. The sources available do not specify the facility's planned location within Japan, the projected production capacity, or the timeline for when manufacturing is expected to begin. Further details are anticipated as the agreement moves through formal defense and procurement channels on both sides.

Why it matters

Co-producing advanced air-to-air missiles in Japan would expand regional defense manufacturing capacity and signal a deeper integration of US-Japan military capabilities at a time of heightened tensions in the Indo-Pacific. The arrangement also sets a precedent for US allies taking on greater roles in producing American weapons systems domestically.

What's next

Further details on the facility's location, production timeline, and capacity are expected as the agreement advances through formal defense and procurement processes in both countries.

Key facts

• The agreement was announced on Wednesday by Japan's defense chief
• The missile to be jointly produced is the Advanced Medium-Range Air-to-Air Missile (AMRAAM)
• The production facility will be located in Japan
• This is described as the latest in a series of defense cooperation actions between the US and Japan
• The sources do not specify a location within Japan, production volume, or a start date

Bias & framing notes

All three sources appear to carry identical wire-service text under different outlet names, providing no independent corroboration of details. The reporting captures the announcement but lacks specifics such as facility location, capacity, or timeline, limiting the depth of verifiable facts available.
