HILL AIR FORCE BASE, Utah, Oct. 22 (UPI) -- Upgraded AN/FPS-117 long-range radar systems for the U.S. Air Force were deemed effective and certified, the Air Force announced on Wednesday.
The AN/FPS-117 is an active electronically scanned array 3-D radar system developed by Lockheed Martin, which provides advanced warning and air traffic surveillance. Upgrades to the system were done through the Essential Parts Replacement Program, which gave a boost to the system's maintenance and control, beacon, power supply, communications, and local control terminal systems.
