On 1 October 1991, the 58th Tactical Training Wing adopted the Air Force Objective Organization Plan, and was re-designated simply as the 58th Fighter Wing (58 FW). All operational fighter training squadrons were reassigned to the new 58th Operations Group (58 OG). Training units also re-designated as "Fighter Squadrons". Units assigned to the 58 OG were: 310th Fighter Squadron, F-16C/D Fighting Falcon 311th Fighter Squadron, F-16C/D Fighting Falcon 312th Fighter Squadron, inactivated, aircraft to 310th, 311th, 314th FS 314th Fighter Squadron, F-16C/D Fighting Falcon 461st Fighter Squadron, F-15E Strike Eagle (reassigned back from 405th FW, 1 October 1991) 550th Fighter Squadron, F-15E Strike Eagle (reassigned back from 405th FW, 1 October 1991) 555th Fighter Squadron, F-15C/D Eagle (reassigned back from 405th FW, 1 October 1991) In 1991, the Base Realignment and Closure (BRAC) commission ordered that all flightline activities cease at MacDill AFB by 1993. The host unit at MacDill AFB, the 56th Fighter Wing, would move its F-16 training to Luke AFB, and Luke would be an exclusive F-16 Fighting Falcon training base. The F-15s would be reassigned to Seymour Johnson AFB, North Carolina in order to accommodate additional F-16 training
