When a Submarine's Janitor Became Japan's Most Feared 'Torpedo Magician

#wwiihistory #submarinewarfare #untoldheroes In October 1943, American submarines were losing the Pacific War. The Mark 14 torpedo—America's primary submarine weapon—had a catastrophic 82% failure rate. Submarine commanders watched helplessly as their torpedoes ran too deep, exploded prematurely, or failed to detonate entirely. Then came John Allen Casper, a 23-year-old Torpedoman's Mate Third Class with only a high school education. Working alone in torpedo rooms late at night, Casper discovered what Navy engineers with advanced degrees had missed: systematic tolerance errors causing torpedoes to run 10 feet deeper than set. His unauthorized modifications transformed American submarine warfare, tripling torpedo effectiveness and shortening the Pacific War by months. This is the incredible true story of the "Torpedo Magician"—the enlisted man who saved thousands of American lives and changed naval warfare forever, yet returned to obscurity after the war.
