The 323d Expeditionary Operations Group is a provisional United States Air Force unit assigned to the United States Air Forces in Europe. As a provisional unit, it may be activated or inactivated at any time.


During World War II, the group's predecessor unit, the 323d Bombardment Group was a Martin B-26 Marauder bombardment group assigned to the Eighth and later Ninth Air Force. The group served in the European Theater of Operations, earning a Distinguished Unit Citation for its actions interdicting German reinforcements during the Battle of the Bulge. After VE Day, the group returned to the United States where it was inactivated. From 1947 to 1951 the group was active in the Air Force Reserves. It was called to active duty for the Korean War, but was inactivated after its personnel were used to bring other units up to full strength.

The group was again active during the 1950s as the 323d Fighter-Bomber Group, flying North American F-86 Sabres and North American F-100 Super Sabres at Bunker Hill Air Force Base, Indiana. It remained inactive until 1991, when it became the 323d Operations Group at Mather Air Force Base, California, where it trained navigators until it was inactivated in 1993.

    The unit was first activated in August 1942 at Columbia Army Air Base, South Carolina as the 323d Bombardment Group with the 453d, 454th, 455th and 456th Bombardment Squadron assigned as its original squadrons. It trained under Third Air Force in the southeastern United States with Martin B-26 Marauders. The group moved to England beginning in April 1943. The flight echelons few via the southern ferry route except for that of the 456th Squadron, which flew the northern route. The ground echelon sailed on the RMS Queen Elizabeth.

    Combat in the European Theater

    The group arrived at RAF Horham in Suffolk on 12 May 1943. The group was assigned to the Eighth Air Force's 3d Bombardment Wing, part of VIII Bomber Command.

    In June 1943, the group and all other Eighth Air Force B-26 units became part of VIII Air Support Command and relocated south to bring them closer to the continent of Europe and the area in which it was planned to establish an American tactical Air force. The group moved to RAF Earls Colne, where it replaced the 94th Bombardment Wing. in June 1943 and inaugurated medium-altitude bombing missions on 16 July 1943, the first medium bomber missions flown by Eighth Air Force at medium altitude, in contrast to the low altitude attacks the unit had trained for in the States. During the summer of 1943 its principal targets were marshalling yards, airfields, industrial plants, military installations, and other targets in France, Belgium, and the Netherlands.

    Along with other Marauder units of the 3d Wing, the 323d transferred to Ninth Air Force in October 1943, which moved from Egypt to absorb the resources of VIII Air Support Command. The group flew missions against V-1 flying bomb and V-2 rocket sites along the coast of France and attacked airfields at Leeuwarden and Venlo in conjunction with the Allied campaign against the Luftwaffe and aircraft industry during Big Week, from 20 to 25 February 1944.

    The 323d helped to prepare for Operation Overlord, the invasion of Normandy, by bombing coastal defenses, marshalling yards, and airfields in France and struck roads and coastal batteries on D-Day, 6 June 1944. On 21 July the group moved south to RAF Beaulieu in Hampshire, a move designed to extend its range over western France. The group participated in the aerial attacks supporting Operation Cobra the breakout at Saint Lo and began flying night missions against fuel and ammunition dumps.

    Between 16 and 26 August, the 323d moved to Lessay Airfield in France, the main movement of aircraft taking place on the 26th. The group struck strong points at Brest and supported the advance on the Siegfried Line. During the Battle of the Bulge, the 323d hit transportation targets to prevent enemy reinforcements from reaching the Ardennes, earning a Distinguished Unit Citation for its efforts.

    As Allied forces advanced into Germany, the group struck interdiction targets in the Ruhr. By VE Day, the group was based at AAF Station Gablingen, Germany and participated in the disarmament program. The group returned to the United States in December and was inactivated at the Port of Embarkation on 12 December 1945.

    Air Force Reserve

    The group was activated in September 1947 in the Air Force Reserve at Tinker Air Force Base, Oklahoma. The group was equipped with the Douglas A-26 Invader light bombardment aircraft and trained under the supervision of the 177th AF Base Unit (later the 2592d Air Force Reserve Training Center). In June 1949, when Continental Air Command implemented the wing base organization, the group was assigned to the 323d Bombardment Wing. The wing was manned at 25% of normal strength but the group was authorized four squadrons rather than the three of active duty units. All reserve combat units were mobilized for the Korean war. The group and was ordered to active duty in the second wave of reserve mobilizations for the Korean War on 10 March 1951. Its personnel were used as fillers for other units, with Strategic Air Command receiving first choice, and the group was inactivated a week later.

    Fighter operations

    The group was redesignated the 323d Fighter-Bomber Group and activated at Bunker Hill Air Force Base, Indiana in August 1955. It initially trained with North American F-86F Sabres, these were quickly upgraded to the F-86H Sabre and then to the North American F-100 Super Sabre The 323d inactivated on 1 September 1957, when the base was transferred to Strategic Air Command.

    Navigator Training

    On 15 December 1991, Air Training Command implemented the Objective Wing concept at Mather Air Force Base and the group was reactivated as the 323d Operations Group of the 323d Flying Training Wing. The Base Realignment and Closure directed that Mather close on 30 September 1993. Group squadrons began to inactivate in early 1992 and the group and its remaining squadrons were inactivated on 31 May 1993, and its mission and most of its Boeing T-43 aircraft were reassigned to the 12th Operations Group at Randolph Air Force Base, Texas.
