History
Established in June 1942 as a B-17 Flying Fortress heavy bombardment squadron, the squadron trained under the Second Air Force; it deployed to the European Theater of Operations (ETO) in September 1942, being assigned to VIII Bomber Command in England. It began flying long-range strategic bombardment missions on 17 November 1942 and attacked such targets as submarine pens, docks, harbours, shipyards, motor works and marshalling yards in France, Germany and the Low Countries. It continued attacks on enemy cities, manufacturing centers, transportation links and other targets until the German capitulation in May 1945.

After combat missions ended, the squadron moved to St Trond Air Base in Belgium in July, 1945 where it conducted photo-mapping and intelligence-gathering flights called Project 'Casey Jones' over Europe and North Africa. On 15 December 1945 it moved to Lechfeld Airfield, Germany which it had bombed on 18 March 1944 and now used as an occupation base. The squadron was inactivated on December 1946 in Germany.

The squadron was reactivated under Strategic Air Command (SAC) in 1951 with B-47A (later B) Stratojet medium jet bombers. It began flying operational strategic bombardment and refueling missions from MacDill AFB, Florida. In 1955, SAC upgraded the squadron to the B-47E, the major production version of the Stratojet. The squadron, still with B-47s, was reassigned to Bunker Hill AFB, Indiana in May 1959. In September 1960, it upgraded to the B-58 Hustler supersonic medium bomber and was declared operationally ready in August 1962.

It began phasing down B-58 operations in 1969, and was inactivated in January 1970.
