Today the site is part of the Joint Surveillance System (JSS), designated by NORAD as Western Air Defense Sector (WADS) Ground Equipment Facility G-35.

It was programmed to be a split site with the headquarters of the 669th Aircraft Control and Warning Squadron and dormitories located on Oak Mountain, about 18 miles south of Vandenberg AFB.

The site was activated on 23 June 1962 during the construction period, and other squadron personnel were assigned during the months prior to its formal establishment.

As a GCI station, the squadron's role was to guide interceptor aircraft toward unidentified intruders picked up on the unit's radar scopes.

In the early part of 1963, Lompoc AFS was given the added responsibility of having a limited GCI capability in the DMCC room.

Upon its activation, Lompoc AFS joined Semi Automatic Ground Environment (SAGE) system, feeding data to DC-17 at Norton AFB, California.
