The US State Department has approved a possible Foreign Military Sale to the Government of Japan of RAM Block 2 Tactical Missiles and related equipment for an estimated cost of $55.311 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 fifty-one (51) Rolling Airframe Missiles (RAM) Block 2 Tactical Missiles, RIM-116C.  Also included are RAM Guided Missile Round Pack Tri-Pack shipping and storage containers, operator manuals and technical documentation, U.S. Government and contractor engineering, technical and logistics support services, and other related elements of logistical and program support.  The estimated total cost is $55.311 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 Asia-Pacific region. 

These RAM Block 2 Tactical missiles will provide significantly enhanced area defense capabilities over critical East Asian and Western Pacific air and sea-lines of communication.

The prime contractor will be Raytheon Missiles and Defense Company, Tucson, AZ.  There are no known offset agreements proposed in connection with this potential sale.

The sale comes at a time of increased tensions between Japan and its neighbors such as North Korea and China.

Acording to Raytheon information, The RAM is a quick-reaction fire-and-forget weapon, designed to destroy anti-ship missiles. Requiring no additional direction upon launch, its passive radio frequency and infrared guidance design provide high firepower to engage multiple threats simultaneously.

The Block 2 variant, the latest evolution in the development of the RAM missile, has a larger rocket motor, advanced control section and an enhanced RF receiver capable of detecting the quietest of threat emitters. The improvements make the missile two and a half times more maneuverable, with one and a half times the effective intercept range. This provides the Block 2 variant with the capability to defeat highly stressing threats, increasing the survivability of the defended ship.

Launching system

The MK 44 guided missile round pack and the MK 49 guided missile launching system, which hold 21 missiles, comprise the MK 31 guided missile weapon system. A variety of existing ship sensors can readily provide the target and pointing information required to engage the anti-ship threat.
