History

The squadron was first activated as an Aircraft Control and Warning Squadron (AC&W Sq) in 1947 at McChord Field, WA Abstract, History of 635 AC&W Sq, May-Dec 1947
(accessed 5 Apr 2012) with a mission to detect and warn of aircraft and defend an area to the west of the Cascade Mountains. To accomplish its mission, it had detachments at Arlington, Washington, Arlington, WA (WW II Site F-50), Neah Bay, WA (Det E, WW II Site J-55), Bellingham, Washington, Bellingham, WA, Spokane AFB, WA (WW II 4 AF Site 129), Coleville, Washington, Coleville, WA, Pacific Beach, Washington, Pacific Beach, WA (Det D, WW II Site B-61, Lashup Site L-35), Sequim, WA (Det F), Everett, Washington, Everett, WA (Det B, Lashup Site L-31) and Fort Stevens (Oregon), Fort Stevens, OR (Lashup Site L-36, Det C), located on World War II Sites.

(accessed 5 Apr 2012) Its main search radar to perform this mission at this time was the AN/CPS-5. In the early 1950s, most of its detachments were replaced by separate squadrons. The squadron moved to Fort Lawton, WA in 1960. It joined the Semi Automatic Ground Environment (SAGE) system and was redesignated as a Radar Squadron in 1960.Cornett & Johnson, p. 155 It was inactivated in 1963. The Squadron was activated again in 1973 to replace Operating Location G of the 630th Radar Squadron at Dauphin Island AFS as part of the Southern Air Defense System (SADS). SADS had been established because of the inadequacy of the radar coverage to the south of the United States that had been dramatically illustrated whan a Cuban MiG-17 went undetected before it landed at Homestead AFB,Leonard, p. 172 and two years later, an An-24 similarly arrived unannounced at New Orleans International Airport. As a result, ADC established SADS with the squadron operating a manual control center at the Houston ARTCC and added radars to supplement the existing Federal Aviation Administration coverage in the area. However, the squadron was inactivated little more than a year later.
