The 54th Airlift Squadron is a United States Air Force squadron stationed at Scott Air Force Base, Illinois. The squadron is an active duty associate unit aiding the 932d Airlift Wing in performance of its airlift mission. The first predecessor of the squadron was formed in August 1917 as the 54th Aero Squadron and served in France during World War II. In 1936, this unit was consolidated with the 54th School Squadron, a pilot training unit that became the 54th Bombardment Squadron, which became a demonstration unit for the Air Corps Tactical School, and later a test and evaluation unit for medium bomber aircraft and tactics.
