The Defense Security Cooperation Agency (DSCA) has notified Congress about support for the maintenance of Aegis-class destroyers and Foreign Military Sales (FMS) for services to Japan.

Approved by the US State Department, the estimated total cost of FMS and related equipment is $ 134 million.

Under FMS, Japan requested the purchase of Subsequent Technical Support (FOTS) Aegis-class destroyer, Aegis computer software updates, system integration and testing, national and onsite engineering support, and all other necessary services.


Japan has also sought, among other things, system upgrades, hands-on operation and maintenance, combat system integration, installation of program patches and adaptive data, and annual service contracts.

In addition, the proposed sales include engineering, technology, and logistical support services from the US Government and contractors.

The proposed FMS is expected to ensure that the Maritime Self-Defense Force (JMSDF) Aegis Destroyer Fleet and Japan’s Computer Program Test Site (JCPTS) continue to strengthen the country’s defense capabilities.

DSCA states: “There are no known set-off agreements proposed in connection with this potential sale.

“Implementation of this proposed sale will require a temporary allocation of five US Government and two contractor representatives to Japan.”

Separately, the US State Department has also approved the possibility of an FMS for a rolling airframe missile (RAM) block 2 tactical missile to Japan.

Under an estimated $ 61.5 million sale, Japan requested up to 40 RIM-116C RAM block 2 tactical missiles, RAM guided missile round pack 3 pack transport and storage containers, operation manuals, and related equipment.

Raytheon Missiles and Defense has been appointed as the prime contractor for the FMS program.

RAM is an advanced self-defense weapon system designed to protect vessels of all sizes from anti-ship cruise missiles and asymmetric threats. US approves sales of Aegis-class support service to Japan
