The US Defense Security Cooperation Agency (DSCA) has notified Congress of a possible foreign military sale (FMS) of Standard Missile-3 (SM-3) Block IIA missiles to Japan.
The potential $133.3m FMS was requested by the Government of Japan and has been approved by the US State Department.
Japan is slated to procure four SM-3 Block IIA missiles and four MK 29 missile canisters under the possible deal.
The sale package includes US Government and contractor technical assistance, transportation, and engineering and logistics support services, in addition to other related elements of logistical and programme support.
The FMS is expected to provide Japan with an improved ballistic missile defence capability in order to assist the defence of the country’s homeland, as well as US personnel stationed in the region.
Raytheon Missile Systems’ site in Tucson, Arizona, and BAE Systems’ facility in Minneapolis, Minnesota, will serve as the principal contractors for the potential sale.
Raytheon is set to deliver the SM-3 Block IIA missiles under the arrangement, while BAE Systems will be responsible for supplying the MK 29 missile canisters.
Developed in cooperation with Japan, Raytheon’s SM-3 Block IIA interceptor can be deployed both on land and at sea.
The missile features larger rocket motors that enable it to defend broader areas from ballistic missile threats, and a larger, enhanced kinetic warhead that helps improve its search, discrimination, acquisition and tracking functions to address emerging threats.
Japan initially requested the FMS of Standard Missile-2 (SM-2) Block IIIB missiles, equipment and support for an estimated cost of $821m in July last year.
