The Pratt & Whitney PW2000, also known by the military designation F117 and initially referred to as the JT10D, is a series of high-bypass turbofan aircraft engines with a thrust range from 37,000 to 43,000 lbf (160 to 190 kN). Built by Pratt & Whitney, they were designed for the Boeing 757.
The aircraft was damaged beyond repair, but some of its parts could be salvaged. [5] On 10 November 1988, the long-rumored existence of the F-117 Stealth Fighter was finally officially confirmed by the Pentagon. [5] In 1990 the last F-117A was delivered. and the flight test squadron no longer had to perform acceptance flights at Groom Lake.
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 ...

A stealth engineer at Lockheed, Denys Overholser, read Ufimtsev’s publication and realized that he had developed the mathematical theory and tools necessary for finite element analysis of radar reflection. [3] This discovery played a key role in the design of the first true stealth aircraft, the Lockheed F-117.
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).
