The Lockheed F-117A Nighthawk, nicknamed "The Black Jet", is the world's first operational aircraft completely designed around stealth technology. Flown only by the United States Air Force, it is a direct descendant of the Have Blue stealth prototype program.
The F-117A was widely publicized during the Gulf War. Retirement looms on the horizon, with dates being discussed ranging from 2008 to 2018.
