Contract Notice, Washington DC, 31 January 2025: The State Department has made a determination approving a possible Foreign Military Sale to the Government of Japan of Standard Missile 6 (SM-6) Block I Missiles and related equipment for an estimated cost of $900 million. The Defense Security Cooperation Agency delivered the required certification notifying Congress of this possible sale today.

The Government of Japan has requested to buy up to one hundred fifty (150) Standard Missile 6 (SM-6) Block I missiles. The following non-MDE items will also be included: MK 21 Mod 3 Vertical Launch System (VLS) canisters; component parts and support equipment; continued Engineering, Integration and Test (EI&T) materiel and support required to produce the SM-6 Block I missiles; special test and handling equipment; training and training equipment and aids; technical publications and data; US Government and contractor engineering and technical assistance, including related studies and analysis support; and other related elements of logistics and program support. The estimated total cost is $900 million.

This proposed sale will support the foreign policy goals and national security objectives of the United States by improving the security of a major ally that is a force for political stability and economic progress in the Indo-Pacific region.

The proposed sale will improve Japan’s capability to meet current and future threats by allowing the Japan Maritime Self Defense Force (JMSDF) to deploy the latest Standard Missile capabilities from their current and future AEGIS Weapon System (AWS) equipped surface combatants. The proposed sale will further

enhance Japan’s capability to protect Japan and local allied land forces and will significantly improve Japan’s contribution to integrated air missile defence in the Indo-Pacific region. Japan will have no difficulty absorbing these articles and services into its armed forces. The proposed sale of this equipment and support will not alter the basic military balance in the region.

The principal contractor will be RTX Corporation, located in Camden, AR. At this time, the US Government is not aware of any offset agreement proposed in connection with this potential sale. Any offset agreement will be defined in negotiations between the purchaser and the contractor.

Implementation of this proposed sale will not require the assignment of any additional US Government or contractor representatives to Japan. There will be no adverse impact on US defence readiness as a result of this proposed sale.
