Constituted as 4th Fighter Group on 22 Aug 1942. Activated in England on 12 Sep 1942. Former members of RAF Eagle Squadrons formed the nucleus of the group, which served in combat from Oct 1942 to Apr 1945 and destroyed more enemy planes in the air and on the ground than any other fighter group of Eighth AF. Operated first with Spitfires but changed to P-47's in Mar 1943 and to P-51's in Apr 1944. On numerous occasions escorted bombers that attacked factories, submarine pens, V-weapon sites, and other targets in France, the Low Countries, or Germany. Went out sometimes with a small force of bombers to draw up the enemy's fighters so they could be destroyed in aerial combat. At other times attacked the enemy's air power by strafing and dive-bombing airfields. Also hit troops, supply depots, roads, bridges, rail lines, and trains. Participated in the intensive campaign against the German Air Force and aircraft industry during Big Week, 20-25 Feb 1944. Received a DUC for aggressiveness in seeking out and destroying enemy aircraft and in attacking enemy air bases, 5 Mar-24 Apr 1944. Flew interdictory and counter-air missions during the invasion of Normandy in Jun 1944. Supported the airborne invasion of Holland in Sep. Participated in the Battle of the Bulge, Dec 1944-Jan 1945. Covered the airborne assault across the Rhine in Mar 1945. Moved to the US in Nov. Inactivated on 10 Nov 1945.
Activated on 9 Sep 1946. Equipped with P-80's. Converted to F-86 aircraft in 1949. Redesignated 4th Fighter-Interceptor Group in Jan 1950. Moved to Japan, Nov-Dec 1950, for duty with Far East Air Forces in the Korean War. Began operations from Japan on 15 Dec 1950 and moved to Korea in Mar 1951. Escorted bombers, made fighter sweeps, engaged in interdiction of the enemy's lines of communications, flew armed reconnaissance sorties, conducted counter-air patrols, served as an air defense organization, and provided close support for ground forces. One member of the group, Maj George A Davis Jr, commander of the 334th squadron, was awarded the Medal of Honor for action on 10 Feb 1952 when, leading a flight of two F-86's, Davis spotted twelve enemy planes (MiG's), attacked, and destroyed three before his plane crashed in the mountains. The group returned to Japan in the fall of 1954. Redesignated 4th Fighter-Bomber Group in Mar 1955.
