Today the Federal Aviation Administration (FAA) operates the site as part of the Joint Surveillance System (JSS).

The station was established as a consolidation of Army and Air Force radar units in the Seattle area due to funding reductions.

On 11 June, Fort Lawton AFS joined the Semi Automatic Ground Environment (SAGE) system, feeding data to DC-12 at McChord AFB.

In addition to the main facility, Fort Lawton operated an AN/FPS-14 Gap Filler site: In late 1962, an AN/FPS-26 height-finder radar was installed.

On 31 December 1962, Air Force moved the 635th RADS to Dauphin Island AFS, Alabama, however a detachment operated at Fort Lawton until March 1963.
