The 637th Radar Squadron is an inactive United States Air Force unit. It was last assigned to the 25th Air Division, Aerospace Defense Command, stationed at Othello Air Force Station, Washington.[1]
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.
