Radars of the United States Air Force

The AN/APG-77 is a multifunction X-band, low probability of intercept radar (LPIR) installed aboard the F-22 Raptor fighter aircraft. The radar was designed and initially built by Westinghouse and Texas Instruments, and production continued with their respective successors Northrop Grumman and Raytheon after acquisition.

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 AN/APG-68 radar is a long range pulse-Doppler radar designed by Westinghouse (now Northrop Grumman) to replace the AN/APG-66 radar in the General Dynamics F-16 Fighting Falcon. The AN/APG-68 radar was itself to be replaced on US Air Force F-16C/D Fighting Falcon Block 40/42 and 50/52 by the AN/APG-83 AESA radar.

The AN/APG-81 is an active electronically scanned array (AESA) fire-control radar designed by Northrop Grumman Electronic Systems (formerly Westinghouse Electronic Systems) for Lockheed Martin’s F-35 Lightning II.

The AN/APG-66 radar is an X-band solid state medium range (up to ) pulse-Doppler planar array radar originally designed by the Westinghouse Electric Corporation (now Northrop Grumman) for use in early generations of the F-16 Fighting Falcon. Later F-16 variants use the AN/APG-68 or the AN/APG-83. This radar was employed in all domestic and export versions of the F-16A/B models throughout the production. Subsequent upgrades have been installed in many varying aircraft types including the U.S. Customs and Border Protection's C-550 Cessna Citation, US Navy P-3 Orion, and Piper PA-42 Cheyenne II's

AESA technology provides quick updates on multiple targets, and its solid-state antenna construction makes it more reliable and cost-effective than traditional radar systems. The radar has a range of up to tracking multiple targets simultaneously.

Required to fit into the tight confines of the originally radar-less F-5, the system offered relatively simple air-to-air modes and a short detection range. The AN/APQ-157 was a similar system with dual displays and controls for the twin-seat F-5F trainer. Many of the F-5s still flying have been upgraded to the improved AN/APQ-159.

The AN/FPS-35 was a long range early warning radar used within the SAGE network and its successors. It was one of the largest air defense radars ever produced, with an antenna across supported on one of the largest rolling-element bearings in the world.
