In 1946, the squadron moved to Castle Field, which was to be its home for the rest of its existence. It trained for bomber operations and also conducted the flying phase of B-52 aircrew training until inactivating in 1971. It was reactivated at Castle in the training mission in 1986 as the 329th Strategic Bomber Training Squadron.
Engaged in long-ranger strategic bombardment operations over Occupied Europe. Deployed to IX Bomber Command in Egypt in December 1942; operating from airfields in Libya and Tunisia. Raided enemy military and industrial targets in Italy and in the southern Balkans, including the Nazi-controlled oilfieldsatPolesti, Romania receiving a Distinguished Unit Citation for its gallantry in that raid. Also flew tactical bombing raids against Afrika Korps defensive positions in Tunisia; supporting British Eighth Army forces in their advance to Tunis, in September and October 1943.
Returned to England with disestablishment of IX Bomber Command in North Africa. From England, resumed long-range strategic bombardment raids on Occupied Europe and Nazi Germany, attacking enemy military and industrial targets as part of the United States' air offensive. The squadron was one of the most highly decorated units in the Eighth Air Force, continuing offensive attacks until the German capitulation in May 1945.
Having returned to the United States in June 1945; being re-manned and re-equipped with Boeing B-29 Superfortress heavy bombers. Trained for deployment to the Central Pacific Area to carry out very long range strategic bombing raids over Japan. Japanese capitulation in August canceled plans for deployment, instead became Continental Air Command (later Strategic Air Command) B-29 squadron.
Began upgrading to the new Boeing B-50 Superfortress, an advanced version of the B-29 in 1950. The B-50 gave the unit the capability to carry heavy loads of conventional weapons faster and farther as well as being designed for atomic bomb missions if necessary. By 1951, the emergence of the Soviet MiG-15 interceptor in the skies of North Korea signaled the end of the propeller-driven B-50 as a first-line strategic bomber. Received Boeing B-47 Stratojet jet bombers in 1954, and in 1955 began receiving early model of the Boeing B-52 Stratofortress. The squadron ceased operations on 14 September 1971 and inactivated at the end of the month.[3]
