The AN/APG-77 system itself exhibits a very low radar cross-section, supporting the F-22's stealthy design. [3] The upgraded APG-77(V)1 may have an even greater range. Much of the technology developed for the APG-77 was used in the AN/APG-81 radar for the F-35 Lightning II , and in turn the technology from the APG-81 was applied to the upgraded ...
The Lockheed Martin/Boeing F-22 Raptor is an American twin-engine, all-weather, supersonic stealth fighter aircraft.As a product of the United States Air Force's Advanced Tactical Fighter (ATF) program, the aircraft was designed as an air superiority fighter, but also incorporates ground attack, electronic warfare, and signals intelligence capabilities.
The F-22 radar from Lot 5 aircraft onward is the APG-77(V)1, which draws heavily on APG-81 hardware and software for its advanced air-to-ground capabilities. [5] In August 2005, the APG-81 radar was flown for the first time aboard Northrop Grumman's BAC 1–11 test aircraft. The radar system had accumulated over 300 flight hours by 2010.
F-4 and early F-5 Lightning photo reconnaissance variants were factory converted by Lockheed at Burbank, California; all later F-5 conversions were made after delivery by Lockheed's Dallas Modification Center near Dallas, Texas. F-4-1 was based on the P-38E, ninety-nine built with initial delivery March 1942. Four nose-mounted K-17 cameras.
The AN/APG-78 Longbow is a millimeter-wave fire-control radar (FCR) target acquisition system and the Radar Frequency Interferometer (RFI), which are housed in a dome located above the main rotor. [4] [5] The radome's raised position enables target detection while the helicopter is behind obstacles (e.g. terrain, trees or buildings). The APG-78 ...
The AN/SPY-1 [a] is a United States Navy passive electronically scanned array (PESA) 3D radar system manufactured by Lockheed Martin, and is a key component of the Aegis Combat System. The system is computer controlled and uses four complementary antennas to provide 360-degree coverage.
The USMC is leveraging the USAF's experience with "fifth-generation air warfare" in the F-22, as they develop their own tactics for the F-35. [39] According to Lockheed Martin in 2004, the only fifth-generation jet fighter then in operational service was their own F-22 Raptor. [2] [40] Lockheed Martin uses "fifth-generation fighter" to describe ...
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. [1] [2] 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.
