The F117 Nighthawk






Airplane : Lockheed F117 Type : Camouflage caps hunters

The F117 Nighthawk or Stealth fighter is one of the worlds strangest looking aircraft and the first operational machine to fully utilise stealth technology. It's design minimises both radar and infrared signitures by using a combination of special materials, angles and shielded jet intakes/outlets. Being black and flying at night help to hide the stealth fighter as well.
The Lockheed 'Skunkworks' in California started development of this aircraft in 1978 and the first flight was made in 1981. Delivery was made to the USAF between 1982 and 1990 and totaled 54 aircraft.
