Stealth: example of the F-117A Nighthawk

The "invisible"F-117A Nighthawk night fighter, a so-called"stealth aircraft" has a very weak radar signature obtained by:

  • a very special design of the envelope consisting of a multitude of sharp-edged facets on which electromagnetic waves are concentrated and then dispersed;
  • a special coating, a sort of "skin", made of a material that absorbs electromagnetic waves;
  • the lowest possible engine gas temperature to reduce the infrared signature of the aircraft's engines as much as possible.
