F-117 Nighthawk | Stealth Attack Aircraft developed by Skunk Works
Ғылым және технология
The Lockheed F-117 Nighthawk is a retired American single-seat, twin-engine 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.
The F-117 was based on the Have Blue technology demonstrator. The Nighthawk's maiden flight took place in 1981 at Groom Lake, Nevada, and the aircraft achieved initial operating capability status in 1983. The aircraft was shrouded in secrecy until it was revealed to the public in 1988. Of the 64 F-117s built, 59 were production versions, with the other five being prototypes.
The F-117 was widely publicized for its role in the Persian Gulf War of 1991. Although it was commonly referred to as the "Stealth Fighter", it was strictly an attack aircraft. F-117s took part in the conflict in Yugoslavia, where one was shot down by a surface-to-air missile (SAM) in 1999. The U.S. Air Force retired the F-117 in April 2008, primarily due to the fielding of the F-22 Raptor. Despite the type's official retirement, a portion of the fleet has been kept in airworthy condition, and Nighthawks have been observed flying since 2009.
In 1964, Pyotr Ufimtsev, a Soviet mathematician, published a seminal paper titled Method of Edge Waves in the Physical Theory of Diffraction in the journal of the Moscow Institute for Radio Engineering, in which he showed that the strength of the radar return from an object is related to its edge configuration, not its size. Ufimtsev was extending theoretical work published by the German physicist Arnold Sommerfeld. Ufimtsev demonstrated that he could calculate the radar cross-section across a wing's surface and along its edge. The obvious and logical conclusion was that even a large aircraft could reduce its radar signature by exploiting this principle. However, the resulting design would make the aircraft aerodynamically unstable, and the state of computer technology in the early 1960s could not provide the kinds of flight computers which would later allow aircraft such as the F-117 and B-2 Spirit to stay airborne. By the 1970s, when Lockheed analyst Denys Overholser found Ufimtsev's paper, computers and software had advanced significantly, and the stage was set for the development of a stealth airplane.

It was a black project, an ultra-secret program for much of its life; very few people in the Pentagon knew the program even existed. The project began in 1975 with a model called the "Hopeless Diamond" (a wordplay on the Hope Diamond because of its appearance). The following year, the Defense Advanced Research Projects Agency (DARPA) issued Lockheed Skunk Works a contract to build and test two Stealth Strike Fighters, under the code name "Have Blue". These subscale aircraft incorporated jet engines of the Northrop T-38A, fly-by-wire systems of the F-16, landing gear of the A-10, and environmental systems of the C-130. By bringing together existing technology and components, Lockheed built two demonstrators under budget, at $35 million for both aircraft, and in record time.
The maiden flight of the demonstrators occurred on 1 December 1977. Although both aircraft crashed during the demonstration program, test data proved positive. The success of Have Blue led the government to increase funding for stealth technology. Much of that increase was allocated towards the production of an operational stealth aircraft, the Lockheed F-117A, under the program code name "Senior Trend".

With the current 5th gen, and the 6th gen NGAD on the horizon, stealth is one of these planes top features and it's a major focus of American R&D. None of the other things they can do could be accomplished without stealth
The humility shown by sharing the 1st flights with the other 2 test pilots on the F-22 & F-35 was the best part of the whole show. And I did not know the F-117 had been retired. I would have thought it could at least be regulated to a "Trainer" status.

Derived from Have Blue, it had swepted wings and inward-canted vertical stabilizers. The airplane was called (The Hopeless Diamond). The Have Blue made its initial flight in December 1977. Kelly Johnson did not like the design calling it a God-Damn diamond in comparsion to his design, the steath drone D-21.

Just for knowing that F-117 that got shot down was flying a target approach that had been used the two nights prior to the shootdown. The previous aircraft tracks had been followed by an old Wurzburg radar (560 mhz +/- 53 cm. wavelength), good enough to track but not to target. Complacency and illusions about invincibility lead to not changing the approach route. After that it was locate it twice or three times the you knew when and where to shoot.9

I was able to see a stealth fighter with my own eyes , in a hanger at Holliman Air force base. My nephew was stationed there. He had to go in over the weekend to do some routine maintenance on another plane. We drove out to a remote location , on the base. I remember approaching a stop sign , that was a crossing with a runway . He told me to " come a complete stop, and remain there for a few seconds, or you will be in trouble, and I will be in a lot of trouble. " He did his work for only a few minutes. I waited in the lunch room. When he finished, we sat and talked for a few minutes. ( I had a feeling that we were on camra and being listened to. ) He ask me if I wanted to see something that I have never seen before ? We walked a little wase into the hanger. I saw a few planes. I don't even remember what they looked like now. We walked a little further and he said " we have to stop now. " He said " look towards the back of the hanger." There it was. We were quite a ways off. I didn't dare to step any further back. I will never forget looking upon that stealth fighter ! WHAT AN AMAZING SIGHT!

This video suggests that the F-117 was developed by "Kelly Johnson's Skunkworks" but it was Ben Rich , who took over for Johnson after he retired, that headed up the 117. Johnson at first told Rich to abandon the project because of the obvious difficulties they encountered.

Member when they were flying the F-117 over Belgium in the late 80's / early 90's? They would fly it at like 1000 feet and 5 knots over highly populated areas. Member? Sorry, had to make a little joke. Very cool plane, but it is NOT "responsible for most triangular UFO sightings". Anyway, great vid. Skunk Works does such amazing things.
I love the F117 if i could fly id be tempted to steal one. I have a little model of it on my shelf, such a beauty
I used to get flown in and out of the Nevada test range during the testing of the F117 and I never saw it out there. That is not to say it was not there, but I or any others never saw it.
