Japan has asked the United States for medium-range air-to-air missiles and associated equipment through the U.S. Foreign Military Sales program,

The Defense Security Cooperation Agency, which oversees FMS sales, notified Congress of the potential deal which is worth an estimated $33 million.

"The Government of Japan requires these missiles for national defense, regional security, inventory modernization, and U.S. interoperability," the agency said. "This sale will enhance the Japan Air Self-Defense Force's ability to defend Japan's territory and protect critical Japanese and U.S. installations.

"Japan, which currently has AIM-120C5 missiles in its inventory, will have no difficulty absorbing these additional missiles into its armed forces."

The proposed sales package is for 17 AIM-120C7 Advanced Medium Range Air-to-Air Missiles, or AMRAAMs, two captive air training missiles, containers, missile support and test equipment, support equipment and spare and repair parts.

Logistics support services, and other related elements of logistics and program support are also included.

Raytheon Missile Systems would be the principal contractor, and multiple trips to Japan involving U.S. government and contractor personnel would be required for technical reviews, support and program management.

U.S. contractor representatives would also be required in Japan to conduct modification kit installation, testing, and training.

DSCA said the U.S. State Department has given its approval for the deal.
