The Lockheed F-117 is a single-seat, twin-engine stealth ground-attack aircraft that is operated by the United States Air Force.  The F-117 was the first flyable aircraft to be designed around stealth technology. It retired in 2008 because of the F-22 Raptor. It is shaped to deflect radar signals. It is limited to subsonic speed. It’s weird 2d shape was from the 1970’s era computer technology.
