Today the site is part of the Joint Surveillance System (JSS), designated by NORAD as Western Air Defense Sector (WADS) Ground Equipment Facility J-79.

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 1959 Mica Peak AFS received an AN/FPS-6A height-finder radar, and began performing air-traffic-control duties for the Federal Aviation Administration (FAA).

During 1960 Mica Peak AFS joined the Semi Automatic Ground Environment (SAGE) system, initially feeding data to DC-15 at Larson AFB, Washington.

In addition to the main facility, Mica Peak operated several AN/FPS-14 Gap Filler sites: Over the years, the equipment at the station was upgraded or modified to improve the efficiency and accuracy of the information gathered by the radars.
