'''Stealth technology''', invented by aSoviet 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.
