Established as a B-24 Liberator heavy bombardment unit in mid-1943; assigned to II Bomber Command for training. Primarily trained in New Mexico and Utah received deployment orders for the Mediterranean Theater of Operations (MTO) in November 1943.

Engaged in very long range strategic bombing missions to enemy military, industrial and transportation targets in Italy, France, Germany, Austria, Hungary, Romania, and Yugoslavia, bombing railroad marshalling yards, oil refineries, airdrome installations, heavy industry, and other strategic objectives.
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 March 1944; knocked out gun positions in preparation for the invasion of Southern France in August 1944; and assisted the final Allied drive through Italy in April 1945 by hitting such targets as bridges, gun positions, and troop concentrations.
