B-29 Superfortress very heavy bombardment squadron. A cadre reformed at Sioux Falls Army Air Field, South Dakota in the middle of the month. The Japanese surrender in August led to the inactivation of unit on 28 August. Conversion to reserve and Korean mobilization The 459th was reactivated as a reserve unit at Long Beach Army Air Field, California in April 1947. By July, all four of its World War II squadrons had been activated, with group headquarters and three squadrons at Long Beach, while the 759th Squadron was at Davis–Monthan Field. Also located at Davis–Monthan and assigned to the group was the 57th Fighter Squadron. Although nominally a heavy bomber unit, the group trained with North American T-6 Texans and Beechcraft T-7 Navigators and T-11 Kansans under the supervision of the 416th AAF Base Unit (later the 2347th Air Force Reserve Flying Training Center) of Air Defense Command (ADC) at Long Beach and the 419th AAF Base Unit (later the 2348th Air Force Reserve Flying Training Center) at Davis–Monthan. In July 1948, Continental Air Command (ConAC) assumed responsibility for managing reserve and Air National Guard units from ADC. President Truman’s reduced 1949 defense budget required reductions in the number of units in the Air Force. ConAC also reorganized its reserve units under the wing base organization system in June 1949, making the group and its squadrons at Long Beach surplus. The group's personnel and equipment at Long Beach were transferred to other reserve units. However, the May 1949 Air Force Reserve program called for a new type of unit, the corollary unit, which was a reserve unit integrated with an active duty unit. The plan called for corollary units at 107 locations. It was viewed as the best method to train reservists by mixing them with an existing regular unit to perform duties alongside the regular unit. The group's 756th Squadron moved on paper to Smoky Hill Air Force Base, Kansas, where it was reassigned and became a corollary of Strategic Air Command's 301st Bombardment Wing. Meanwhile group headquarters moved without personnel or equipment to Davis–Monthan Air Force Base, where the 57th Fighter Squadron was inactivated and the group and its 759th Squadron became corollaries of Strategic Air Command (SAC)'s 43d Bombardment Group. Along with all other reserve corollary units, the group was mobilized for the Korean War. Once the group was mobilized in May 1951 SAC reassigned its personnel
