The U.S. government authorized a potential sale to Korea of AIM-9X air-to-air missiles and related equipment in Washington on Friday. The State Department said the proposed Foreign Military Sale is estimated at $125 million and still needs congressional notification and review. Korea requested 103 AIM-9X Sidewinder Block II tactical missiles, 10 guidance units, training aids, spare parts and other non-major defense items. The department said the sale would help expand Korea’s air defense capability and ensure interoperability with U.S. forces.
