Today the site is part of the Joint Surveillance System (JSS), designated by NORAD as Western Air Defense Sector (WADS) Ground Equipment Facility J-29A.

Ajo was one of the most expensive ADC radar stations to be constructed, with costs mounting to approximately $7.4 million for 100 structures located within housing, cantonment, operations, ground-air transmitter-receiver (GATR) areas.

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

During 1961 Ajo AFS joined the Semi Automatic Ground Environment (SAGE) system, feeding data to DC-21 at Luke AFB, Arizona.

The National Park Service demolished the station site in 1994 and restored it to its natural state, including removal of thee concrete building pads.
