Established in September 1950, just after the start of the Korean War, and became operational later in 1950, manned by the 759th AC&W Squadron. The station initially had an early warning mission and a Ground Control Intercept mission. The early warning mission involved tracking and identifying all aircraft entering their airspace while the GCI mission involved guiding interceptor aircraft to their targets. Initial equipment included the TPS-1B height-finder/search radar and a CPS-5 search radar mounted on top of Battery Mishler at Fort Stevens. The old gun emplacements had been covered over with a concrete roof when the battery was converted to an HECP during World War II. The unit headquarters was located in the Fort Stevens Guard House and the underground portion of Battery Mishler served as the operations and maintenance center for the squadron. The 759th moved to Naselle Air Force Station Washington on 1 Jan 1951 but the Lashup site at Fort Stevens remained operational until February 1952.
