The 505th Bombardment Group is an inactive United States Air Force unit. Its last assignment was with Thirteenth Air Force, stationed at Clark Field, Philippines. It was inactivated on 30 June 1946.
The unit served primarily in the Pacific Ocean theater of World War II as part of Twentieth Air Force. The 505th Bomb Group's aircraft engaged in B-29 Superfortress bombardment operations against Japan. Its aircraft were identified by a "K" (January to March 1945) or "W" (April to September 1945) inside a Circle painted on the tail.
The unit was established in early 1944 at Dalhart Army Air Field, Texas, being formed as a B-29 Superfortress Very Heavy bombardment Group. Thu unit was formed with four bomb squadrons, being a mixture of both new and reassigned units. The 482d, 484th and 485th having World War I origins and the 483d being a newly constituted unit.
Due to a shortage of B-29s, the group was equipped with former II Bomber Command B-17 Flying Fortresses previously used for training heavy bomber replacement personnel. The group was eventually equipped with newly manufactured B-29 Superfortresses at Harvard Army Airfield, Nebraska during the summer of 1944. In May shortages in aircraft and equipment led to the 485th Bomb Squadron being inactivated, with its personnel being consolidated into other group squadrons and the 505th becoming a three squadron group (the 485th would be reactivated a month later as part of the 501st Bombardment Group).
