The 320th Missile Squadron is a United States Air Force unit. It is assigned to the 90th Operations Group, stationed at F.E. Warren AFB, Wyoming. The 320 MS is equipped with the LGM-30G Minuteman III Intercontinental ballistic missile (ICBM), with a mission of nuclear deterrence.
History
World War II
The squadron was first organized as the 320th Bombardment Squadron at Key Field, Mississippi in April 1942 as a Consolidated B-24 Liberator unit and one of the original squadrons of the 90th Bombardment Group. The squadron trained with Liberators in the southeastern United States under III Bomber Command until August.
The squadron moved to Willow Run Airport, Michigan for conversion training on newly manufactured Ford Liberators. Assigned to VII Bomber Command with B-24Ds, the unit moved to Hickam Field, Hawaii in September. The squadron arrived in northern Queensland, Australia in November 1942 and began bombardment missions under V Bomber Command almost immediately.
The squadron attacked enemy airfields, troop concentrations, ground installations and shipping in New Guinea, the Bismarck Archipelago, Palau and the southern Philippines. The squadron was awarded a Distinguished Unit Citation for its operations in Papua through January 1943. The unit participated in the Battle of Bismarck Sea in March 1943, and earned another citation for strikes on enemy airfields at Wewak, New Guinea in September 1943 despite heavy flak and fighter opposition.
During 1944, the squadron took part in the New Guinea Campaign until the end of June, then made long-range raids on oil refineries at Balikpapan, Borneo, in September and October. In January 1945, the squadron moved to the Philippines and supported ground forces on Luzon, attacked industrial targets on Formosa, and bombed railways, airfields, and harbor facilities on the Asiatic mainland. Shortly before the end of the war in the Pacific, the 90th moved to Okinawa, from which it would be able to strike the Japanese home islands.
After VJ Day, the squadron flew reconnaissance missions over Japan and ferried Allied prisoners of war from Okinawa to Manila. It ceased operations by November 1945. The squadron was inactivated in the Philippines in early 1946.
Superfortress operations
The squadron was reactivated in July 1947 as a very heavy unit at Andrews Field, Maryland. It was a component of one of seven bombardment groups activated at Andrews by Strategic Air Command (SAC) that day. Most of these units, including the 320th, were inactivated by September 1948 and it does not appear they were manned during this period.
The squadron was again organized at Fairchild Air Force Base, Washington in January 1951 and equipped with the Boeing B-29 Superfortress. In February, as part of a reorganization of Strategic Air Command wings, the 90th Bombardment Group was reduced to paper status and the squadron was attached to the wing for operational control. In June 1952, this organization, which was designed to permit the wing commander to focus on the wing's combat units and the maintenance necessary to support combat aircraft, was formalized as the Dual Deputy Organization and the squadron was assigned to the wing.
In March 1951, the squadron moved to Forbes Air Force Base, where it served primarily as a training unit. In May, it began serving as an Operational Training Unit for B-29 aircrews and mechanics of newly-activating units. The squadron help organize and train the 376th, 308th, and 310th Bombardment Wings.
In June, the squadron added duty as a Replacement Training Unit, primarily providing individual training for aircrew being assigned to existing Far East Air Forces B-29 units during the Korean War. In November 1952 it also began training replacement crews for the RB-29 reconnaissance model of the Superfortress and SHORAN personnel for Strategic Air Command (SAC). These training activities continued through November 1953.
