Lockheed F-117 Nighthawk

Lockheed F-117 Nighthawk is a stealth ground attack aircraft which is only possessed by the United States Air Force. This aircraft is the result of the program Lockheed Have Blue stealth aircraft, and is the first aircraft designed specifically for use stealth technology.

Lockheed F-117 Nighthawk Design
The F-117 is shaped to deflect radar signals and is about the size of an F-15 Eagle. The single-seat Nighthawk is powered by two non-afterburning General Electric F404 turbofan engines, and has quadruple-redundant fly-by-wire flight controls. It is air refuelable. To lower development costs, the avionics, fly-by-wire systems, and other parts are derived from the General Dynamics F-16 Fighting Falcon, McDonnell Douglas F/A-18 Hornet and McDonnell Douglas F-15E Strike Eagle. The parts were originally described as spares on budgets for these aircraft, to keep the F-117 project secret. The F-117 Nighthawk has a radar signature of about 0.025 m2 (0.269 sq ft).
