  ## History
  
  ### World War II
  
  The squadron was activated in early 1942 under III Fighter Command in North Carolina. Initially trained with P-39 Airacobras, re-equipped with P-38 Lightnings.
  
  Moved overseas, October 1942 – February 1943, the ground echelon arriving in French Morocco with the force that invaded North Africa on 8 November, and the air echelon, which had trained for a time in England, arriving in North Africa between late December 1942 and early February 1943.
  
  Began combat with Twelfth Air Force in January 1943. Supported ground operations during the Allied drive against Axis forces in Tunisia. Patrolled the coast of North Africa and protected Allied shipping in the Mediterranean Sea, April–July 1943. Provided cover for the convoys that landed troops on Pantelleria on 11 June and on Sicily on 10 July 1943. Supported the landings at Anzio on 22 January 1944 and flew patrols in that area for a short time.
  
  Reassigned to the China-Burma-India Theater (CBI) and moved to India, February–March 1944. Initially performed training with P-40 and P-47 aircraft. Moved to China in May and became part of Fourteenth Air Force. Continued training and on occasion flew patrol and escort missions before returning to full-time combat duty in January 1945. Attacked enemy airfields and installations, flew escort missions, and aided the operations of Chinese ground forces by attacking troop concentrations, ammunition dumps, lines of communications, and other targets to hinder Japanese efforts to move men and materiel to the front.
  
  Inactivated in China on 27 December 1945.
  
  ### Cold War
  
  Reactivated at Wheeler Field, Hawaii Territory in late 1946. Equipped with P-51 Mustangs and performed air defense of the Hawaiian Islands until 1949. Was reassigned to the Tactical Air Command Ninth Air Force, being stationed in New Mexico. Re-equipped with F-80 Shooting Star jet aircraft, trained as a tactical fighter squadron. Upgraded to F-86 Sabres in 1950.
  
  Reassigned to Air Defense Command, becoming part of the Western Air Defense Force, being moved to Moses Lake AFB, Washington. In Washington the squadron's mission was the air defense of eastern Washington, including the Grand Coulee Dam and the Hanford Nuclear Reservation.
  
  **United States Air Forces in Europe**
  
  Ordered to the United Kingdom in 1951, mission to assist the Royal Air Force in the Air Defense of East Anglia, being assigned to the newly refurbished RAF Bentwaters. Also operated from a dispersed station, RAF Shepherds Grove about forty miles apart.
  
  The squadron was one of the first Sabre Jet unit to be based in Europe, and the first to form an integral part of the peacetime air defense of Great Britain. In this role, the squadron came under the operational control of the RAF Fighter Command No. 11 Group during the actual defense of the United Kingdom, and for combined operational training. Under USAFE, the squadron came under the control of Third Air Force which coordinated its activities with the RAF.
  
  In October 1954 the mission of the squadron changed from fighter-interceptor to fighter-bomber operations, carrying both conventional and nuclear weapons. The squadron was charged with tactical operations in support of USAFE and NATO, with air defense as a secondary mission. To reflect this change, the unit traded in its F-86s for the F-84F Thunderstreak.
  
  Beginning in the fall of 1958, the squadron was reequipped with the McDonnell F-101 Voodoo. The F-101 was configured as a fighter bomber, intended to carry a single nuclear weapon for use against battlefield targets such as airfields. The Voodos were equipped with Low Angle Drogued Delivery (LADD) and Low Altitude Bombing System (LABS) equipment for its primary mission of delivering nuclear weapons at extremely low altitudes. Pilots were trained for one-way missions into Soviet territory to increase effective range at some cost in negating pilot recovery.
  
  In November 1965, the squadron received McDonnell F-4 Phantom II to replace the Voodoos. Initially receiving the F-4C this was later upgraded to the more capable F-4D during late 1972 and 1973. Began conversion to the Republic A-10 Thunderbolt II in June 1979. The A-10 being a single-seat, twin-engine jet aircraft designed to provide close air support (CAS) of ground forces by attacking tanks, armored vehicles, and other ground targets. With the A-10, the squadron's mission changed to close air support and battlefield air interdiction in support of NATO ground forces.
  
  With the end of the Cold War in 1991, the USAF presence at Woodbridge and its sister base Bentwaters was gradually phased down. It was announced that the base would be closed and the squadron would be inactivated. Squadron was inactivated on 14 August 1992.
  
  ### UAV operations
  
  The squadron was redesignated the 91st Attack Squadron and activated at Creech Air Force Base, Nevada, where it is an associate of the 432d Wing.
