Constituted as 373d Fighter Group on May 1943. Activated on 15 Aug 1943. Trained for combat with P-47's. Moved to England, Mar-Apr 1944. Assigned to Ninth AF. Flew first combat mission, a fighter sweep over Normandy, on 8 May 1944, and then took part in preinvasion activities by escorting B-26's to attack airdromes, bridges, and railroads in France. Patrolled the air over the beachhead when the Allies launched the Normandy invasion on 6 Jun 1944, and hit troops, tanks, roads, fuel depots, and other targets in the assault area until the end of the month. Moved to the Continent in Jul 1944; struck railroads, hangars, boxcars, warehouses, and other objectives to prevent enemy reinforcements from reaching the front at St Lo, where the Allies broke through on 25 Jul 1944. Bombed such targets as troops, gun emplacements, and armored vehicles to aid ground troops in the Falaise-Argentan area in Aug 1944. During the Battle of the Bulge, Dec 1944-Jan 1945, concentrated on the destruction of bridges, marshalling yards, and highways. Flew armed reconnaissance missions to support ground operations in the Rhine Valley in Mar 1945, hitting airfields, motor transports, and other objectives. Received a DUC for a mission, 20 Mar 1945, that greatly facilitated the crossing of the Rhine by Allied ground forces: without losing any planes, the group repeatedly dived through barrages of antiaircraft fire to bomb vital airfields east of the river; also attacked rail lines and highways leading to the Rhine, hitting rolling stock, motor transports, and other objectives. Continued tactical air operations until 4 May 1945. Returned to the US, Jul-Aug 1945. Inactivated on 7 Nov 1945.
