The 485th Bombardment Squadron is an inactive United States Air Force unit. It was last assigned to the 505th Bombardment Group. It was inactivated at Northwest Field, Guam on 10 June 1946.

History[]

Activated in August 1917 as an Air Service Aero Squadron during World War I. Was apparently a non-flying support squadron, deployed to France in early 1918 and supported Air Service operations on the Western Front. Remained in France after the Armistice, returning to New York City, demobilizing in May 1919.

Reactivated as part of the Army reserve forces in 1924, assigned to Wright or Patterson Field at Dayton Ohio. Although designated as a bombardment squadron, it is unclear if the unit had any aircraft assigned to it. Disbanded in 1942.

Reconstituted in 1944 as a B-29 Superfortress Very Heavy bombardment squadron; assigned to Second Air Force for training. Initially assigned to 505th Bombardment Group, however shortages in aircraft and equipment led to personnel being consolidated into other group squadrons; inactivated. Reactivated about a month later; assigned to 501st Bombardment Group and equipped with B-29B limited production aircraft.

After completion of training deployed to Central Pacific Area (CPA), assigned to XXI Bomber Command, Northwest Field (Guam) for operational missions. B-29Bs were standard production aircraft stripped of most defensive guns to increase speed and bomb load, The tail gun was aimed and fired automatically by the new AN/APG-15B radar fire control system that detected the approaching enemy plane and made all the necessary calculations.

Mission of the squadron was the strategic bombardment of the Japanese Home Islands. Dntered combat on 16 June 1945 with a bombing raid against an airfield on Moen. Flew first mission against the Japanese home islands on 26 June 1945 and afterwards operated principally against the enemy's petroleum industry. Flew primarily low-level, fast attacks at night using a mixture of high-explosive and incendiary bombs to attack targets.

Flew last combat mission on 15 August 1945, later flew in "Show of Force" mission on 2 September 1945 over Tokyo Bay during formal Japanese Surrender. Inactivated on Guam 15 April 1946, personnel returned to the United States and aircraft sent to storage in Southwest United States.
