The U.S. Defense Security Cooperation Agency (DSCA), the Department of Defense agency responsible for arms sales, announced that the State Department has approved a possible Foreign Military Sale of the AIM-120C-7 Advanced Medium-range Air-to-air Missile (AMRAAM) to Japan. According to the DSCA press release, the Japanese government has requested the possible sale of 56 AMRAAMs at an estimated cost of $113 million. AMRAAM is an active radar guided air-to-air missile, carrying a 22.7 kg HE warhead over a range of 55-75 km, and reaching speeds of up to Mach 4. Congress still needs to approve the sale, and a final deal will need to be agreed upon between the United States and Japan, during which time the cost and number of missiles could change.
