After the war, March was assigned to the new Tactical Air Command (TAC) as part of the postwar reorganization of the Army Air Force.
March was allocated to TAC's Twelfth Air Force.
The first TAC unit to be assigned was the 1st Fighter Group, under the command of Colonel Frank S. Perego, being reactivated at March on 3 July 1946, replacing and absorbing the assets of the wartime 412th Fighter Group.
At the time of its activation, the group's three squadrons (the 27th, 71st, and 94th Fighter Squadrons) flew Lockheed P-80 Shooting Star (after 11 June 1948 F-80), America's first operational jet fighter.

Few members of the 1st Fighter Group foresaw subsequent difficulties in the summer of 1946 as they trained with their new jet fighters.
The 412th had reported in the summer of 1945 that the P-80 would be well suited for bomber escort, counterair, and ground support.
The 1st Fighter Group trained for these and other possible strategic and tactical missions.
Pilot inexperience and mechanical difficulties combined to give the P-80 a high accident rate, while parts shortages curtailed operational training.
Even so, the 1st Fighter Group maintained a heavy schedule of demonstration flights that served to introduce the fighter to a curious public.

On 15 August 1947, the 1st Fighter Wing was activated as part of AAF Regulation 20-15, "Reorganization of AAF Base Units and Installations," on 27 June 1947.
This regulation, which laid out what became known as the Hobson Plan, prescribed a standard organizational setup for all Army Air Force bases worldwide.
In 1947, the 67th Tactical Reconnaissance Group (later Wing) was activated as part of a service-wide, wing-base test and assigned to March.
When the wing was activated, only the 67th Reconnaissance Group was fully operational.
The group was equipped with FA-26 Invaders (RB-26 after 1948) and Lockheed FP-80s (RF-80s after 1948) and was integrated with the 1st Fighter Wing, performing a wide array of day and night photographic missions in southern California.
Budget constraints, though, resulted in the wing's inactivation in March 1949.
