The 871st Bombardment Squadron is an inactive United States Air Force unit. During World War II it was assigned to the 497th Bombardment Group until it was inactivated on 31 March 1946. The squadron was activated in late 1943. After training in the United States, it moved to Saipan, where it served in the strategic bombing campaign against Japan with Twentieth Air Force, flying Boeing B-29 Superfortress aircraft in the Pacific Theater of Operations, where it earned two Distinguished Unit Citations. Following V-J Day, the squadron returned to the United States and briefly became part of Strategic Air Command before inactivating.
