'''Stealth technology''', invented by Soviet Russian electrical engineer and mathematical physicist Pyotr Ufimtsev, makes an [[aircraft]] or ship difficult or impossible to detect by radar or other electronic detection systems.  [[American]] engineers developed this new technology in the 1970s and several types of aircraft have been constructed using it.  This minimizes the ability of enemies to shoot down the <!-- OUR? russia is also developing stealth! --> aircraft and capture or kill the pilots.  Their radiation-absorbent material (RAM) coatings need to be reapplied every few missions, which takes large amounts of manpower and time. Once the coatings are gone, the planes are visible to radars.

Stealth technology makes use of the following approaches:

Stealth technology makes use of the following approaches:

*Reduction in [[radar]] cross-section (RCS) through clever shapes, anti-radar electronic signalling, radar-absorbing paint and non-metallic materials
