Reassigned to the Air Defense Command (ADC) First Air Force on 1 December 1948.
With the new ADC assignment, moved to Otis Air Force Base, Massachusetts on 16 November 1948 as part of the 26th Air Division.
In February 1949, transitioned to North American F-86A Sabre day interceptor with the F-84s being sent to Republic Aircraft for refurbishment and reassignment to Air National Guard units.

The squadron moved to Goose Air Base, Labrador under Northeast Air Command (NEAC) on 28 October 1952, assigned to NEAC's 64th Air Division, headquartered at Pepperrell Air Force Base.
The 59th first operated the Lockheed F-94B Starfire all-weather night fighter interceptors with a detachment at Thule Air Base, subsequently the Northrop F-89 Scorpion jet interceptors from the airfield, assisting in the air defense of the region.
 When SAC received jurisdiction of the United States facilities at Goose in 1957 with the inactivation of NEAC, ADC took over the USAF atmospheric defense forces (including the 64th Air Division).
 The 59th was upgraded to the Convair F-102A Delta Dagger supersonic interceptor in 1960.
It continued defensive patrols over the region.

Moved to Bergstrom Air Force Base, Texas in 1967 and was upgraded to the McDonnell F-101B Voodoo and the F-101F operational and conversion trainer.
The two-seat trainer version was equipped with dual controls, but carried the same armament as the F-101B and were fully combat-capable.
 Moved to Kingsley Field, Oregon in 1968 then inactivated on 31 December 1969 as part of the drawdown of ADC interceptor bases, the aircraft being passed along to the Air National Guard.
