How Soviet Math and Pyotr Ufimtsev Created the First Stealth Aircraft

Recreating the math behind the first stealth aircraft

I explore how Pyotr Ufimtsev's 1971 Soviet paper on electromagnetic scattering was ignored by the West but later used by Lockheed Skunk Works to design the F-117 Nighthawk. As a software engineer, I break down the complex physics of Radar Cross Section (RCS) and the Physical Optics method, showing how simplified math made stealth technology possible when computers were too weak for exact solutions.

"The F-117 strived to be completely invisible, using a technique pioneered by physics rather than engineering."
