The AN/FPS-117 is an L-band active electronically scanned array (AESA) 3-dimensional air search radar first produced by GE Aerospace in 1980 and now part of Lockheed Martin. The system offers instrumented detection at ranges on the order of and has a wide variety of interference and clutter rejection systems.
The system was originally developed as part of the "Seek Igloo/Seek Frost" effort to replace the older radar systems of the DEW line with designs that could be operated remotely and require much less maintenance as part of DEW's replacement, the American-Canadian North Warning System (NWS). Implementation of the NWS resulted in a reduction in operations and maintenance spending by up to 50% compared to previous systems.
