The 75th BS was also replaced by the 668th Bombardment Squadron, one of the unit's World War II historical bombardment squadrons. The 41st Air Refueling Squadron and 56th Munitions Maintenance Squadron transferred to the 416th. The 4039th's maintenance and security squadrons were replaced by ones with the 416th numerical designation of the newly established wing. Each of the new units assumed the personnel, equipment, and mission of its predecessor. Under the Dual Deputate organization, all components were directly assigned to the wing, no operational or maintenance group element was activated. The history, lineage and honors of the 416th Bombardment Group were temporarily bestowed upon the newly established wing upon activation.
