The squadron was originally activated at Long Beach Municipal Airport CA as the 637th Aircraft Control & Warning Squadron as part of the initial cold war air defenses of the Western United States.[citation needed] The following year it moved to Lashup Site L-32 at McChord AFB, WA.[2] In 1959, it moved to Site L-29 at Moses Lake AFB, WA.[2]

The squadron finally moved to its final station at site LP-40 (later P-40, Z-40) on Saddle Mountain, WA in 1951.[1] In 1960, the unit was integrated into the Semi Automatic Ground Environment (SAGE) control system and was redesignated the 637th Radar Squadron (SAGE).[1] Because it was stationed at a Backup Interceptor Control (BUIC) site, it was inactivated in 1970 and replaced by the like numbered 637th Air Defense Group (ADG).[1] As defense systems against manned bomber threats were reduced, it was activated once again in 1974 to replace the 637th ADG.[1] It was last inactivated on 31 March 1975.[1]

The unit was a General Surveillance Radar squadron providing for the air defense of the United States.
