The AN/APG-77 is a multifunction low probability of intercept radar installed on 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. It is a solid-state, active electronically ...
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.
As of December 2020, the only combat-ready stealth aircraft in service are the Northrop Grumman B-2 Spirit (1997), the Lockheed Martin F-22 Raptor (2005), the Lockheed Martin F-35 Lightning II (2015), [15] [16] the Chengdu J-20 (2017), [17] and the Sukhoi Su-57 (2020), [18] with a number of other countries developing their own designs. There ...
In September 2020, AN/SPY-7(V)1 was chosen by Canada as the primary radar for its future River-class destroyer along with CMS-330 Combat Management System with Aegis Combat System. [ 10 ] Lockheed Martin promoted this version of radar as the AN/SPY-1 refurbishment program to the US Navy to extend the lifespan of the Ticonderoga -class cruiser ...
The F-4 Phantom had a Texas Instruments AAA-4 infrared seeker [4] under the nose of early production aircraft F-4Bs and F-4Cs. It was not not installed on later F-4Ds due to limited capabilities, [5] but retained the bulge and indeed some F-4Ds had the IRST receiver retrofitted in a modified form. [3]
In order to fly the F-22, Larson said he had to go through basic pilot training, consisting of 55 weeks of flying in trainer aircraft like the T-6 Texan II and a T-38 Talon.
One means to reduce IR signature is to have a non-circular tail pipe (a slit shape) to minimize the exhaust cross sectional area and maximize the mixing of hot exhaust with cool ambient air (see Lockheed F-117 Nighthawk, rectangular nozzles on the Lockheed Martin F-22, and serrated nozzle flaps on the Lockheed Martin F-35).
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.
