US and Japan Finalize Deal for Japanese AMRAAM Production Facility

Key points

• Japanese Defense Minister Shinjiro Koizumi announced the agreement to build a final assembly and inspection facility for AMRAAM in Japan during a meeting with US Secretary of Defense Pete Hegseth in Cebu, Philippines.
• The joint production effort, referred to as 'Operation Supercharge,' is designed to ensure a steady supply of missiles for the F-35 fighter jet, which is used by both the US and Japanese militaries.
• The agreement follows a recent $20.7 billion contract between the US Pentagon and RTX to expand AMRAAM production over seven years, with annual output targets set at at least 1,900 missiles.
• The deal addresses Japan's constitutional restrictions on exporting lethal weapons and co-producing offensive weaponry, which previously hindered such agreements, and aims to diversify the industrial base for critical munitions.
• Koizumi and Hegseth emphasized the need to strengthen deterrence and response capabilities in the region, citing concerns over China's assertiveness, though neither named China directly in their joint statements.

Background

This development follows a broader trend of US-Japan defense cooperation, including recent joint drills and discussions on increasing defense spending. The US has also been pushing allies to assume greater responsibility for their own security, with the Trump administration urging defense spending to reach 3.5% of GDP. The agreement comes amid escalating tensions in the South China Sea and East China Sea, where the US has reaffirmed its commitment to defend the Philippines and other allies.

How outlets are covering it

AP News and ABC News focused on the announcement of the joint missile production facility and the broader context of US-Japan alliance strengthening in response to China's assertiveness. Air & Space Forces Magazine provided detailed technical and financial context, highlighting the $20.7 billion RTX contract and the specific challenges of Japan's constitutional restrictions on weapon co-production. Japan Today emphasized the agreement's role in boosting cyber cooperation and defense investment, while noting Japan's caution regarding direct demands from Washington to increase defense spending. All sources agreed on the strategic importance of the deal but differed in their emphasis on the technical, financial, and political dimensions.

Why it matters

The establishment of a Japanese facility for AMRAAM production is a significant step in strengthening the US-Japan defense industrial base and ensuring a reliable supply of critical munitions for the F-35 fighter jet. It addresses long-standing supply chain bottlenecks and Japan's historical restrictions on co-producing offensive weapons, which have hindered such agreements. The deal also signals a shift in US policy, pushing allies to invest more in their own defense capabilities and reduce reliance on US production. This move is likely to influence regional security dynamics, particularly in the South China Sea and East China Sea, where tensions with China are escalating.

What to watch

The next steps include the selection of a location for the AMRAAM facility in Japan and the finalization of the production agreement. The US and Japan are expected to continue coordinating on critical munitions production and defense investment, with potential implications for Japan's defense spending and its relationship with the US. The deal may also influence other allies' decisions to co-produce or procure US-made weapons, as the US pushes for greater defense investment among its partners.
