North Charleston AFS was established in 1954 by Air Defense Command as one of a planned deployment of forty-four Mobile radar stations to support the permanent ADC Radar network in the United States sited around the perimeter of the country.

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 late 1959 this site was also performing air traffic control duties for the FAA with a newly installed AN/FPS-20A search radar and AN/MPS-14 set.

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.

The Gap Filler at Parris Island is now part of a golf course; the one at Georgetown County Airport has been redeveloped; the Stateburg site remains, with an existing radome .
