After training was deployed to the European Theater of Operations (ETO), being assigned to VIII Bomber Command in England at RAF North Pickenham.

Entered combat in May 1944, engaging in long-ranger strategic bombardment of enemy industrial targets in central Germany. Attacked airfields and V-weapon launching sites in France during the first week in June. Bombed coastal defenses in Normandy on 6 June 1944 and attacked bridges, railroads, and other interdiction targets in France until the middle of the month. Resumed bombardment of strategic targets in Germany and, except for support of the infantry during the Saint-Lô breakthrough on 25 July 1944. The squadron suffered very high losses of personnel and equipment while engaged in combat; combat losses leading to withdrawal of unit from operations in August 1944 after only 89 days of combat. Remaining equipment and personnel were reassigned to other Eighth Air Fore units in England.
