The 27th FIS was originally transferred to ADC from SAC with F-80s in December 1948. However, the squadron went back under SAC four months later in May 1949. In April 1950 the 27th FIS was again transferred to ADC, still at March AFB, but with new F-86A aircraft. In July 1950 the squadron moved to George AFB for a brief one month when it again moved in August 1950 across the county to Griffiss AFB. In August 1952 the squadron began transitioning into F-89Cs; however, the change was never completed. It continued flying F-86As until the spring of 1954 when a transition into F-94Cs was completed. In the fall of 1957 the unit transitioned into F-l02As.

Two years later in the fall of 1959 the squadron moved to Loring AFB and began flying F-106As. On 1 July 1971 the 27th FIS designation was transferred to TAC as the 27th TFS.
