Army Air Forces School of Applied Tactics at Orlando Army Air Base and Pinecastle Army Air Field, Florida. After organizing at Alamogordo, the group moved to Utah, where the ground echelon was stationed at Kearns Army Air Base, although flying operations were based at Salt Lake City Army Air Base. After completing training at Langley Field, Virginia, the group departed the United States for the Mediterranean Theater of Operations in December 1943. The air echelon began staging through Mitchel Field, New York to ferry their Liberators via the southern ferry route. The ground echelon of group headquarters sailed on the SS William T. Barry. Combat operations The air echelon of the group was delayed in Tunisia and was not entirely lodged at the 455th's combat station of San Giovanni Airfield, Italy until 1 February 1944, and the group flew its first mission on 16 February. The group was engaged primarily in the strategic bombing campaign against Germany, attacking targets like airfields, factories, oil refineries, harbors, marshalling yards in Italy, France, Germany, Austria, Hungary, Romania, and Yugoslavia. On 2 April 1944, the group attacked a ball-bearing plant at Steyr, Austria for which it earned a Distinguished Unit Citation (DUC). The primary target, the Daimler-Pusch aircraft engine factory was obscured by clouds, so the unit attacked the nearby ball bearing plant although attacks by an estimated 75 twin-engine fighters continued through the bomb run and heavy, accurate flak was encountered. The 740th claimed the destruction of seven of these fighters against the loss of one squadron Liberator. The 742d lost two Liberators in the attack but claimed the destruction of six enemy aircraft. Five crewmembers from one of the squadron's B-24s lost in the attack bailed out in territory controlled by Yugoslav Partisans and were able to evade German forces and returned to the squadron a month after the attack. The 743d Squadron claimed the destruction of nine fighters against the loss of two squadron Liberators. On 26 June 1944, the group, which was leading the 304th Bombardment Wing on the raid, encountered fighter opposition that was described as the strongest Fifteenth Air Force had encountered to date, and which destroyed several Liberators of the 455th Group. One 740th Liberator was lost on the raid, while the squadron claimed eleven enemy aircraft destroyed (two shared claims). Enemy fighters were able to separate the 741st Squadron from its fighter escort and intensified their
