The Lockheed F-117A 'Nighthawk' is powered by two low-bypass F404-GE-F1D2 turbofan engines from General Electric. The rectangular air intakes on both sides of the fuselage are covered by gratings, which are coated with radar-absorbent material.
The wide and flat structure of the engine exhaust area reduces the infrared and radar detectability of the aft section of the engine. The two large tail fins slant slightly outwards to provide an obstruction to the infrared and radar returns from the engine exhaust area.
The F-117A has four elevons on the inboard and outboard trailing edge of the wing. The V-shaped tail, which controls the yaw of the aircraft, acts as a flying tail, which means that the whole surface acts as a control surface. The elevons do not act as flaps to reduce the rate of descent for touchdown, so the landing speed of the F-117A is high, at about 180mph to 190mph, and a drag parachute is used.
