The 320th Special Tactics Squadron (320th STS) is a Special Tactics unit of the United States Air Force Special Operations Command, based at Kadena Air Base. The 320th was originally constituted in 1943 during World War II as an aircraft warning unit, the 320th Fighter Control Squadron. The squadron was sent to the Pacific at the end of 1943 and served there until its inactivation and disbandment after the end of the war. It was reconstituted and reactivated in 1992 at Kadena as the 320th Special Tactics Squadron. Initially with the 720th Special Tactics Group, it was soon transferred to the 353rd Special Operations Group.
