World War II
Established as the 74th Aero Squadron, presumably a tactical defense unit, 1918–1919.
Re-established in 1933 at Albrook Field, Panama Canal Zone. Operated Northrop A-17s as a dive-bomber 17th Attack Squadron. Designated as the 74th Bombardment Squadron (Medium) at Albrook Field circa 5 March 1940, converting to Douglas B-18 Bolo. On 20 November 1940, the squadron was again re-designated as the 74th Bombardment Squadron (Heavy). On 14 July, the Squadron moved from Albrook to Howard Field, in anticipation of receipt of its first Boeing B-17B Flying Fortress the following month.
The Squadron moved from Howard Field to Aguadulce Field, Panama, on 8 November 1941 and, following the Pearl Harbor Attack, moved to Rio Hato Army Airfield on 11 December. By 16 January 1942, the unit had been transformed, and found itself at Guatemala City Airport, Guatemala, equipped with six Boeing B-17B's and four B-17E's taken over and consolidated from other units. In August 1942, the Squadron was assigned to the 40th Bombardment Group and this assignment lasted until 12 May 1943. Began conversion to Consolidated B-24D Liberators in mid-1943. By October 1943, the 74th was the only Sixth Air Force tactical unit still operating from Guatemala City Airport and, the following month, ended its association with the 6th Bombardment Group, when that organization was disbanded. It subsequently fell directly under VI Bomber Command.
The period between April and August, the unit moved again to the remote Seymour Island AAF on the Galapagos Islands. The move accomplished, the unit engaged in patrols over the eastern Pacific. The unit returned to Aguadulce Field, Panama, on 13 February 1945 after only some seven months. In May. the Squadron moved to Rio Hato Field, remaining until the end of the war, being inactivated on 1 November 1946.
The squadron was reactivated as the 135th Bombardment Squadron (Medium) on 27 March 1951. It operated B-29 Superfortresses as part of the Federalized 106th Bombardment Group, New York Air National Guard that was elevated to active duty at March AFB, California during the Korean War. The 135th Bomb Squadron continued operations under SAC's Fifteenth Air Force until it was inactivated, with personnel and equipment being assigned to the 320th Bombardment Wing when the guardsmen were relieved from active duty on 1 December 1952.
