On 1 November 1954 the 653d Aircraft Control and Warning Squadron began operations at Alexandria AFB with the activation of AN/MPS-14, AN/TPS-1D, and AN/TPS-10D radars. The site was designated as M-125, 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. The AN/MPS-14 continued to operate until site closure in 1963. In 1958 the site was operating an AN/FPS-20 search set.
