The unit then moved to Pueblo AAB, Colorado for preparation for overseas movement. the ground unit left Pueblo for New York on 12 April 1943. the aircraft began movement on 1 April 1943. In April-May 1943, the unit moved to RAF Polebrook England to serve in combat with Eighth Air Force. It was assigned to the 94th Combat Wing, also at Polebrook. The group tail code was a "Triangle J".

The 351st's first completed combat mission took place on 14 May 1943, when 18 B-17's targeted a German Luftwaffe airfield at Kortrijk, Belgium. As the war progressed, the 351st operated primarily against strategic objectives in Germany, striking such targets as ball-bearing plants at Schweinfurt, communications at Mayen, marshalling yards at Koblenz, a locomotive and tank factory at Hanover, industries at Berlin, bridges at Cologne, an armaments factory at Mannheim, and oil refineries at Hamburg.

The group also struck harbor facilities, submarine installations, airfields, V-weapon sites, and power plants in France, Belgium, the Netherlands, and Norway.

The 351st Received a Distinguished Unit Citation (DUC) for performance on 9 October 1943, when an aircraft factory in Germany was accurately bombed in spite of heavy flak and pressing enemy interceptors. It received another DUC for its part in the successful attack of 11 January 1944, on aircraft factories in central Germany. The group participated in the intensive air campaign against the German aircraft industry during "Big Week", 20–25 February 1944.

In addition to its strategic missions, the group often operated in support of ground forces and attacked interdictory targets.
