1st test flight of US stealth bomber

Stealth aircraft are designed to avoid detection using a variety of technologies that reduce reflection or avoiding being successfully targeted by radar guided weapons.

Stealth aircraft are designed to avoid detection using a variety of technologies that reduce reflection or avoiding being successfully targeted by radar guided weapons. Stealth is a combination of passive low observable (LO) features and active emitters such as low-probability-of-intercept radars, radios and laser designators. These are typically combined with operational measures such as carefully planning mission maneuvers to minimize the aircraft's radar cross-section (RCS), since common hard turns or opening bomb bay doors can more than double an otherwise stealthy aircraft's radar return. Stealth is accomplished by using a complex design philosophy to reduce the ability of an opponent's sensors to detect, track, or attack the stealth aircraft.
