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 first stealth aircraft introduced were the Lockheed F-117 Nighthawk attack aircraft (introduced in 1983) and the Northrop Grumman B-2 Spirit bomber (first flew in 1989). Although no stealthy fighters per se appeared among the fourth generation, some radar-absorbent coatings and other L-O treatments developed for these programs are reported ...
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.
Previous-generation radar low observable (LO) aircraft, also referred to as stealth aircraft, such as the Northrop Grumman B-2 Spirit bomber and Lockheed F-117 Nighthawk ground attack aircraft were not designed for air to air combat, lacking the active electronically scanned array (AESA) radars, low probability of intercept (LPI) data networks ...
In the realignment of F-117A squadrons, the 415th and 416th were assigned production F-117As; the 417th was assigned pre-production F-117As, along with Northrop T-38 Talon trainers for pilot transition training to the F-117. [8] In January 1991, the F-117As of the 417th were deployed to King Khalid Air Base, Saudi Arabia, where they saw combat ...
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.
