F-117 Nighthawk Traditional Cache

The Lockheed F-117 Nighthawk is a single-seat, twin-engine stealth ground-attack aircraft formerly operated by the United States Air Force (USAF). Its first flight was in 1981, and it achieved initial operating capability status in October 1983.^[1] The F-117 was "acknowledged" and revealed to the world in November 1988.^[4]

A product of Lockheed Skunk Works and a development of the Have Blue technology demonstrator, it became the first operational aircraft initially designed around stealth technology. The F-117A was widely publicized during the Persian Gulf War of 1991. It was commonly called the "Stealth Fighter" although it was a ground-attack aircraft.

The Air Force retired the F-117 on 22 April 2008,^[2] primarily because of the fielding of the F-22 Raptor^[5] and the impending introduction of the F-35 Lightning II.^[6] Sixty-four F-117s were built, 59 of which were production versions with five demonstrators/prototypes.
