Redesignated 484th Bombardment Group (Pathfinder) in May 1944 but did not perform pathfinder functions. Redesignated 484th Bombardment Group (Heavy) in Nov 1944. Operated primarily as a strategic bombardment organization, Apr 1944-Apr 1945. Attacked such targets as oil refineries, oil storage plants, aircraft factories, heavy industry, and communications in Italy, France, Germany, Austria, Czechoslovakia, Hungary, Rumania, and Yugoslavia. On 13 Jun 1944 a heavy smoke screen prevented the group from bombing marshalling yards at Munich; however, in spite of severe damage from flak and interceptors, and despite heavy gunfire encountered at the alternate target, the group bombed marshalling yards at Innsbruck and received a DUC for its persistent action. Received second DUC for performance on 21 Aug 1944 when, unescorted, the organization fought its way through intense opposition to attack underground oil storage installations in Vienna. In addition to strategic missions the 484th participated in the drive toward Rome by bombing bridges, supply dumps, viaducts, and marshalling yards, Apr-Jul 1944; ferried gasoline and oil to Allied forces in southern France, Sep 1944; and supported the final advance through northern Italy, Apr 1945.
