Port Isabel Air Force Station (ADC ID: TM-190) is a closed United States Air Force General Surveillance Radar station. It is located 18.7 miles (30.1 km) north-northeast of Brownsville, Texas. It was closed in 1961.
Port Isabel Air Force Station came into existence as part of Phase III of the Air Defense Command Mobile Radar program. On October 20, 1953 ADC requested a third phase of twenty-five radar sites be constructed.
The 811th Aircraft Control and Warning Squadron was moved to the former Port Isabel Auxiliary Naval Air Station on 1 January 1958. It operated an AN/FPS-3A search radar and an AN/FPS-6 height-finder radar at the site, 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.
