Japan to purchase $3.64B in AIM-120 AMRAAM missiles to bolster defense

The State Department has approved a potential $3.64 billion foreign military sale to Japan for up to 1,200 AIM-120D-3 and AIM-120C-8 Advanced Medium-Range Air-to-Air Missiles (AMRAAM), alongside related equipment and support. With RTX Corporation as prime contractor, the sale includes missile guidance sections, training variants, propulsion units, and classified support systems. This transaction is aimed at enhancing Japan's defense capabilities and supporting U.S. foreign policy objectives in the Indo-Pacific region.

The package is expected to strengthen Japan’s ability to counter threats and safeguard U.S. personnel stationed in the country, reinforcing its role as a key regional ally. The deal will not affect the military balance in the region, nor require additional US personnel deployments to Japan. The actual cost may vary based on final requirements and agreements.

While State has approved the potential sale, the final details and cost may vary slightly as Japan and the US finalize the agreement.
