AN/FPS-124

The AN/FPS-124 is an unattended radar (UAR) providing short range, Doppler radar surveillance of airborne targets. It provides target information to the Regional Operations Control Center (ROCC), and employs built-in-test, performance monitoring/fault isolation and system redundancy enabling it to reconfigure itself when fault detection occurs. The AN/FPS-117 and AN/FPS-124 form an array of radars stretching across North America from Alaska, United States to Labrador, Canada. This North Warning System is designed to provide long-range detection and coverage for drug interdiction support and tactical command and control. Implementation of the North Warning System has resulted in a reduction in Operations and Maintenance (O&M) spending by up to 50% compared to previous systems.
