AN/FPS-117 3D radar is an airspace surveillance solid-state system produced by Lockheed Martin Corporation. Electronic elevation scanning is performed by an aerial array permanently rotating in azimuth to provide real time 3D data about any target within the surveyed area. High reliability due to solid-state technology is supplemented by automatic orientation, calibration and reconfiguration as well as continuous computer assisted monitoring and selftesting.

AN/FPS-117 radar system is designed for:

• airspace surveillance;
• detect, track and identify air assets flying within a range up to 450 km and provide 3D data.

The radar system performs radar surveillance, air traffic control, fighters control for interception and target acquisition for ground-to-air missile systems.
It is EW protected and automatically sends radar data to ASOC network, having also a remote capability.
The first radar entered the Romanian Air Force inventory in 1998.
