Constituted as 455th Bombardment Group (Heavy) on 14 May 1943. Activated on 1 Jun 1943. Trained with B-24's. Moved to Italy, arriving in Jan and Feb 1944. Served in combat with Fifteenth AF from Feb 1944 to Apr 1945. Engaged primarily in bombardment of strategic targets such as factories, marshalling yards, oil refineries, storage areas, harbors, and airdromes in Italy, France, Germany, Poland, Czechoslovakia, Hungary, Austria, and the Balkans. Received a DUC for a mission on 2 Apr 1944 when the group contributed to Fifteenth AF's campaign against enemy industry by attacking a ball-bearing plant at Steyr. Although meeting severe fighter opposition and losing several of its bombers on 26 Jun 1944, the group proceeded to attack an oil refinery at Moosbierbaum, receiving another DUC for this performance. In addition to strategic missions in the Balkans, the group bombed troop concentrations, bridges, marshalling yards, and airdromes during the fall of 1944 to hamper the enemy's withdrawal from the region. The group also supported ground forces at Anzio and Cassino in Mar 1944; knocked out gun positions in preparation for the invasion of Southern France in Aug 1944; and assisted the final Allied drive through Italy in Apr 1945 by hitting such targets as bridges, gun positions, and troop concentrations.
