The AN/FPS-117 is an L-band active electronically scanned array (AESA) 3-dimensional air search radar. The system offers instrumented detection at ranges on the order of 200 to 250 nautical miles (370 to 460 km; 230 to 290 mi) and has a wide variety of interference and clutter rejection systems.

As noted by the company, developed for the U.S. Air Force 35 years ago, it provides long-range surveillance capability to the minimally attended Distant Early Warning line in Alaska and Canada. It is the most capable dual-use air traffic monitoring and air defense radar available and has been proven in more locations around the world than any other radar in its class.
