Reactivated in 1952 as part of Air Defense Command as an air defense squadron, initially equipped with F-51D Mustang fighters at Scott Air Force Base, Illinois with a mission for the air defense of St Louis and the western Ohio River Valley.
  Re-equipped in January 1953 with F-86D Sabre Interceptors.
 In 1957 began re-equipping with the North American F-86L Sabre, an improved version of the F-86D which incorporated the Semi Automatic Ground Environment, or SAGE computer-controlled direction system for intercepts.
 The service of the F-86L destined to be quite brief, since by the time the last F-86L conversion was delivered, the type was already being phased out in favor of supersonic interceptors, inactivated on 1 March 1960.
