On 1 March 1955 the 702d Aircraft Control and Warning Squadron began operating AN/MPS-7, AN/TPS-10D, and AN/MPS-14 radars at Hunter, and initially the station functioned as a Ground-Control Intercept (GCI) and warning station. As a GCI station, the squadron's role was to guide interceptor aircraft toward unidentified intruders picked up on the unit's radar scopes. From 1956 to 1958, an AN/GPS-3 also saw service. By 1959 only AN/FPS-20A and AN/MPS-14 sets were operating. Circa 1961 Hunter received an AN/FPS-26 height-finder radar.
