In 1962, the Soviet physicist Pyotr Ufimtsev published a paper on electromagnetic diffraction. Moscow left it unclassified because they thought it was too abstract to matter. When the Air Force translated it in 1971, a Lockheed engineer realized the equations could predict radar cross-sections of complex shapes. That paper became the F-117 Nighthawk and B-2 Spirit.
