The 55th Fighter Wing is a disbanded unit of the United States Air Force, last stationed at Lockbourne Air Force Base, Ohio. It was withdrawn from the Ohio Air National Guard and inactivated on 31 October 1950 when the Guard adopted the Wing Base organizational model and formed the cadre for the 121st Fighter Wing. During World War II, the wing served as the 55th Bombardment Wing in the Mediterranean Theater of Operations, flying strategic bombardment missions against areas under Axis control.
