The Headquarters would later be reassigned to the Western Air Defense Force in February 1950. Initial authorized strength included 18 Officers and 31 enlisted personnel. It was the first postwar Air Warning Station opened by the newly created USAF Air Defense Command

In addition to the Headquarters, and staff functions the station was the site of the Silver Lake Manual Air Defense Control Center (ADCC) established to provide a command and control facility for the fledgling radar network being established in the Pacific Northwest
