This station was one of eight stations established in the final phase of the Permanent AC&W Radar Program for the 33rd Air Division. The 33rd Air Division would remain a manual operation throughout the transition of the rest of the Air Defense System to the semi-automatic SAGE System. The Oklahoma City Manual Direction Center P-86 remained connected to these sites until they closed down one by one. Because the sites were never destined to become SAGE sites they received older less capable equipment and facilities and they were among the first to be closed when budgets constricted. The eight sites were:
| 1. TM-187 Ozona Air Force Station TX | 5. TM-191 Rockport Air Force Station TX |
| 2. TM-188 Eagle Pass Air Force Station TX | 6. TM-192 Killeen Air Force Station TX |
| 3. TM-189 Zapata Air Force Station TX | 7. TM-193 Lufkin Air Force Station TX |
| 4. TM-190 Port Isabel Air Force Station TX | 8. TM-194 Lake Charles Air Force Station LA |
The station initially had both a Ground-Control Intercept (GCI) and early warning mission. The early warning mission involved tracking and identifying all aircraft entering their airspace while the GCI mission involved guiding Air Force interceptors to any identified enemy aircraft. Controllers at the station vectored fighter aircraft at the correct course and speed to intercept enemy aircraft using voice commands via ground-to-air radio.
