  • It aims to strengthen allied missile-production capacity and regional defence preparedness.
• Announcement: On 28 October 2026, Japanese Defence Minister Shinjiro Koizumi announced the agreement following discussions with US Defence Secretary Pete Hegseth on the sidelines of the ASEAN Defence Ministers’ Meeting in the Philippines.
  • The initiative is associated with Operation Supercharge, aimed at expanding allied munitions production.
    • The initiative emerged from discussions beginning in 2024, when Washington and Tokyo explored AMRAAM co-production. 
    • In April 2026, Mitsubishi Electric confirmed discussions of such an agreement.
• Objective: The main objective is to scale up missile production, alleviate strained global military stockpiles, and reinforce Japan’s domestic defense industrial base.
• Details: 
  • The joint facility will be situated in Japan. 
  • Initial component manufacturing—such as electronic circuit boards—will be coordinated with Japanese firms like Mitsubishi Electric alongside U.S. contractor RTX (Raytheon).
  • The agreement covers the local assembly of radar-guided AMRAAMs essential for fifth-generation F-35 Lightning II fighter jets, alongside technical data-sharing to boost production of Standard Missile-3 (SM-3) Block IIA ballistic missile interceptors. 

What is AMRAAM Missile?

• About: The AIM-120 AMRAAM (Advanced Medium-Range Air-to-Air Missile) is an all-weather, beyond-visual-range (BVR) tactical weapon designed to intercept and destroy airborne threats.
  • It operates during both day and night, succeeding the older semi-active radar-guided AIM-7 Sparrow missile. 
  • It provides complete air dominance and allows pilots to attack enemy aircraft from long distances before visual contact is made.
• Developed By: This lethal missile system was originally engineered by Hughes Aircraft Company.
  • It is manufactured and continuously modernized by Raytheon Missiles & Defense (RTX).
    • In February 2026, Raytheon entered a major US defence production arrangement valued at approximately $20.7 billion, targeting annual AMRAAM production of at least 1,900 missiles.
• Origin: The AMRAAM originated in the United States during the late 1970s as a joint U.S. Air Force and U.S. Navy program.
  • It officially entered active military service in September 1991.
• Technology: The missile incorporates advanced active radar homing technology paired with an internal inertial reference unit and microcomputer.
  • A two-way datalink enables mid-course navigation guidance updates directly from the host aircraft before its terminal seeker takes over. 
• Variants:
  • AIM-120A/B: Initial operational generations.
  • AIM-120C: Improved design and compact control surfaces.
  • AIM-120D: Advanced navigation, data-link and engagement capabilities.
  • AMRAAM-ER: Extended-range variant developed for ground-based air defence.
• Features:
  • Capabilities: It possesses a top speed exceeding Mach 4 and a dynamic operating range stretching up to 160 kilometers in its advanced AIM-120D variant.
    • It is highly capable of executing multi-target simultaneous engagement, allowing a single jet to fire at several threats at once. 
  • Fire-and-Forget Autonomy: The integrated active radar seeker allows the pilot to disengage and perform evasive maneuvers immediately after launch while the missile guides itself to the final target intercept.
  • Electronic Counter-Countermeasures: It features specialized software algorithms that enable home-on-jam capabilities, transitioning from active radar to tracking electronic warfare signals if the enemy tries to jam it. 
  • Compact Design Adaptability: Variants like the AIM-120C utilize clipped control wings specifically minimized to comfortably fit within the internal weapons bays of modern aircraft like the Eurofighter Typhoon, JAS 39 Gripen, F-22 Raptor and F-35 Lightning II.
  • Defence Applications: The AMRAAM acts as a vital dual-role weapon system. It serves as the primary interceptor for the ground-based NASAMS (National Advanced Surface-to-Air Missile System) air defense network. 
• Role: The AMRAAM has secured over 13 air-to-air combat victories in prominent war zones, beginning with the Gulf War, followed by operations in Bosnia and Kosovo.
  • In recent geopolitical conflicts like the Russo-Ukrainian War, surface-launched versions have played a major role in protecting critical civilian infrastructure from massive Russian drone and missile barrages. 

US–Japan Defence Cooperation and Bilateral Security Agreements

• The US–Japan security partnership developed after the Second World War.
  • The two countries signed their original security treaty in 1951, followed by the revised Treaty of Mutual Cooperation and Security in 1960.
    • It establishes the foundation of their modern military alliance.
    • It provides for mutual security cooperation, US military presence in Japan and joint responses to armed attacks against territories under Japanese administration, subject to constitutional provisions and each country’s legal processes.
    • It grants the United States the authorization to station roughly 60,000 military personnel across strategic facilities in Japan. In exchange, the U.S. acts as a security guarantee, committing to defend Japan if it faces an armed attack on its territories.
• US–Japan Status of Forces Agreement (SOFA), 1960: The SOFA establishes the legal and administrative framework governing US military personnel stationed in Japan.
  • The United States transformed its regional command by upgrading U.S. Forces Japan (USFJ) to a Joint Force Headquarters with expanded operational power. 
  • This shift coordinates seamlessly with Japan’s newly formed Japan Joint Operations Command (JJOC) to unify cross-domain military activities.
• General Security of Military Information Agreement (GSOMIA), 2007: GSOMIA provides a framework for protecting and exchanging classified military information between the two countries. 
• Guidelines for US–Japan Defence Cooperation (2015): Revised guidelines expanded alliance coordination, including cooperation in peacetime, grey-zone situations, regional contingencies and international security operations.
  • Both countries cooperate in joint research, development, production, testing and evaluation of defence equipment. 
  • They also facilitate the exchange of components, maintenance services and military technologies. 
• Defence Industrial Cooperation, Acquisition and Sustainment (DICAS): DICAS provides an institutional framework for strengthening defence-industrial collaboration, addressing supply-chain vulnerabilities and improving equipment maintenance. 
• US–Japan Security Consultative Committee (2+2): The 2+2 mechanism brings together the US Secretaries of State and Defense and Japan’s Ministers of Foreign Affairs and Defense. It provides high-level policy coordination.
