The facts

  1. Japanese Defence Minister Shinjiro Koizumi and US defence chief Pete Hegseth reached the agreement during their meeting in the Philippines. [1][2]

  2. AMRAAM is the Advanced Medium-Range Air-to-Air Missile. The agreement concerns final assembly and checkout, rather than an announced factory for every missile component. [1][2]

  3. The ministers also agreed to share technical information to expand SM-3 Block IIA interceptor production as part of their equipment and technology cooperation. [1]

Still unconfirmed

  • The facility’s precise location, cost, capacity and opening date were not verified. An agreement is not an operating factory.
