The Lockheed F-117 Nighthawk is a retired American single-seat, subsonic, twin-engined, stealth attack aircraft developed by Lockheed's secretive Skunk Works division and operated by the United States Air Force (USAF). It was the first operational aircraft to be designed with stealth technology.
For the F/A-18, GE based the F404 on the YJ101 engine they had developed for the Northrop YF-17, enlarging the bypass ratio from 0.20 to 0.34 to enable higher fuel efficiency. The engine consists of a three-staged fan, seven axial stage compressor arrangement, single stage low and high pressure turbines, an augmentor, and produces maximum ...
The F-117 while having sufficient stealth, also had a low visual signature. Even still, if the F-117 was visually acquired, it, like all aircraft, were subject to visual air-to-air interception. This was easily circumvented by flying at night. [39] The F-22 Raptor, is an American fifth-generation stealth air superiority fighter
The Lockheed Have Blue was born out of a requirement to evade radar detection. During the Vietnam War, radar-guided SAMs and AAA posed a significant threat to US aircraft.. For this reason, strike aircraft during the war often required support aircraft to perform combat air patrols and suppression of enemy air defenses (SEAD).
The F-104 was the first combat aircraft capable of Mach 2 flight, and the only aircraft in history to simultaneously hold the world speed, rate-of climb and altitude records. [4] Three of the Century Series aircraft—F-101, F-102, and F-106—were armed with nuclear air-to-air missiles.
F-117 is the Lockheed F-117 Nighthawk, an American stealth attack aircraft. F-117 or F117 may also refer to: Pratt & Whitney PW2000 (military designation F117), a turbofan jet engine; HMS Ashanti (F117), a British Royal Navy Tribal-class frigate; HMS Misoa (F117), a British Royal Navy Maracaibo-class LST Mk.I tank landing ship
Northrop and Lockheed were awarded contracts in the first round of testing. Lockheed received the sole award for the second test round in April 1976 leading to the Have Blue program and eventually the F-117 stealth attack aircraft. [15] Northrop also had a classified technology demonstration aircraft, the Tacit Blue in development in 1979 at ...
In February and March 1992 the F-117 test unit moved from Groom Lake to Air Force Plant 42 in Palmdale, California, where Lockheed had produced the aircraft, although some testing, especially RCS verification [jargon] and other classified activity, was still conducted at Groom Lake.
