K-222 Papa: The Soviet Submarine That Outran Torpedoes

December 1970: Soviet submarine K-222 achieved 44.7 knots submerged—a speed record that still stands today. But the Papa-class submarine's revolutionary liquid-metal reactor, designed to make her faster than any torpedo, created thermal signatures visible from orbit and poisoned her crew with lead-bismuth vapor. This is the classified story of how American satellites tracked the fastest submarine ever built, forcing the USSR to abandon series production despite achieving unprecedented underwater speed. Declassified patrol reports, engineering documentation, and medical records reveal the toxic cost of Cold War technological competition and why K-222 remained the only Papa-class submarine ever constructed.
