Shocked: This Plane that Started the Stealth Revolution! HD

The F-117 Nighthawk , America’s original stealth plane with a deeply sinister appearance, is an example of a weapon system designed around the limitations imposed by a promising new technology. The Nighthawk was revolutionary when it entered service in 1983—not that many could appreciate that, as the plane was kept secret from the public for five years. When Lockheed rolled out the first two prototypes in 1977, the angular aircraft looked like nothing that had been seen before—or since. Later stealth designs such as the B-2 Spirit and the F-35 feature curved surfaces. However, the F-117 was designed before there were advanced computers with the calculating power to produce such curved surfaces. Thus, the F-117 alone among stealth aircraft is distinguished by its faceted 2-dimensional design. The constraints this imposed meant the design was aerodynamically unstable, and required sophisticated fight computers combined with quadruple-redundant fly-by-wire controls to compensate and keep the aircraft in a flyable state. The Have Blue prototypes earned the nickname “Wobbly Goblins,” and both crashed during the testing process. The Air Force was nonetheless encouraged by their effectiveness and evading radar detection, and gave the go ahead to produce a production aircraft designated the F-117. The use of a model number over 100 was an anachronism, and for years the public assumed the top secret stealth fighter to be designated F-19. For this reason you can find 19880’s era F-19 model kits, toys, and even a computer game . The first F-117A rolled of the production lines in 1981. In all 64 were built through 1990, including five YF-117 prototypes, at a program cost of $111 million per plane. The production aircraft’s handling was reportedly more forgiving than its predecessors. read more:https://nationalinterest.org/blog/buzz/legend-plane-started-stealth-revolution-47867 ► Before Comment , Please connect your tongue to your brain! ► This video is made under fair use policy, also this material is made from public published domain for people with hearing and seeing disability. • Watch more videos: ► China Can’t Afford To Attack An American Aircraft Carrier https://www.youtube.com/watch?v=knEjXlWNDtk&t=29s ► Why US Navy Tried to Sink Its Own Aircraft Carrier? https://www.youtube.com/watch?v=djCFs189vqI&t=23s ► Here’s how many Billions the US will spend on Nuclear Weapons? https://www.youtube.com/watch?v=O2emGF6C9u4 #f117 #stealth #usmilitary DISCLAIMER: Information, Facts or Opinion expressed in this Video are Presented as Sources and do not reflects views of US Military and hence, US Military is not liable or responsible for the same.
