357th Fighter Squadron  The 357th Fighter Squadron is part of the 355th Fighter Wing at Davis–Monthan Air Force Base, Arizona. It operates Fairchild Republic A-10 Thunderbolt II aircraft training pilots for close air support missions. The squadron was first activated during World War II as a Republic P-47 Thunderbolt fighter squadron. After training in the United States the unit deployed to the European Theater of Operations. The unit entered combat operations in the summer of 1943, continuing in combat until April 1945. It earned a Distinguished Unit Citation for carrying out a difficult attack in April 1944. The squadron moved to Germany, where it was briefly part of the occupation forces before returning to the United States where it was inactivated in November 1945. The 357th conducts all formal course directed aircraft transition, day and night weapons and tactics employment, day and night aerial refueling, and dissimilar air combat maneuvers. The squadron trains pilots to plan, coordinate, execute, and control day and night close air support, air interdiction and battlefield surveillance and reconnaissance. The 355th Fighter Squadron was first activated in late 1942 at Orlando Army Air Base, Florida as one of the original three squadrons of the 355th Fighter Group, flying Republic P-47 Thunderbolts. The squadron trained under III Fighter Command in Florida and in the Middle Atlantic States, then was reassigned as part of I Fighter Command for final training at Philadelphia Municipal Airport, Pennsylvania. The unit also performed air defense in the Philadelphia area in mid-1943. The 357th deployed to the European Theater of Operations (ETO), where it became part of the 65th Fighter Wing of VIII Fighter Command, Eighth Air Force. The squadron engaged in low-level sweeps over the low countries and Occupied France, attacking enemy airfields and targets of opportunity such as locomotives, bridges, radio stations, and armored cars. Later the squadron served primarily as an escort for Boeing B-17 Flying Fortresses and Consolidated B-24 Liberator heavy bombers of VIII Bomber Command during missions into Germany. On 5 April 1944, shortly after converting from P-47's to North American P-51 Mustangs, the squadron successfully bombed and strafed German airfields during a snow squall, for which it earned a Distinguished Unit Citation. It provided fighter cover for Allied forces landing in Normandy on 6 June 1944, and afterwards hit transportation facilities to cut enemy supply lines. The unit hit fuel dumps, locomotives, and other targets in support of ground forces during the breakthrough at Saint-Lô in July.
