This is the super secretive F-117 Nighthawk that was built by Lockheed and developed by the Skunk Works division that was directly tied to the United States Air Force. The first flight was back in June of 1981 making it the first operational aircraft that was designed using new secret stealth technology. It wasn’t until 1988 that the F-117 was introduced to the public.
