History
Established as a B-25 Mitchell medium bombardment squadron in early 1942; trained under Third Air Force. Assigned to Columbia Army Air Base, South Carolina as first an Operational Training Unit (OTU) for newly formed squadrons, then in 1943 becoming a Replacement Training Unit (RTU) for pilots and aircrew on the B-25 prior to the personnel being assigned overseas to combat units. Inactivated on 1 May 1944 with the phaseout of B-25 training.

Reactivated in 1949 in the Air Force Reserve as a Troop Carrier Squadron Programmed for C-46 Commandoes, never manned or equipped. Inactivated in 1951.

Reactivated in 1955 as a Tactical Air Command C-123 Provider Troop Carrier Squadron, being one of the first squadrons being equipped with the aircraft. Deployed to France in 1956 to reinforce NATO and the United States Air Forces in Europe. Flew transport and special air missions (SAM) throughout France, West Germany, Italy, Spain and England. Flew several Dispersed Operating Base supply missions and reduced the need for road convoys. However cost of operations were high and USAFE decided that the C-123s were worth the expense. Aircraft, equipment and personnel returned to Ardmore AFB during July and August 1958 where aircraft and personnel reassigned to squadrons of the 463d Troop Carrier Wing at Sewart AFB, Tennessee. Squadron inactivated as a paper unit in September 1958.
