How One Submarine Sank the Largest Warship Ever Lost at Sea

In November 1944, the Imperial Japanese Navy commissioned the largest warship ever built — Shinano, a 72,000-ton supercarrier converted from a Yamato-class battleship hull. She was rushed to sea unfinished, her watertight doors incomplete, her crew untrained, and her damage control systems untested. Seventy miles away, an American submarine captain who had previously asked to be relieved of command — believing he was not good enough — was given one more chance. This is the story of USS Archerfish and Commander Joseph Enright. The night he tracked the largest warship in history for six hours on the surface, broke doctrine to set his torpedoes shallow, and fired the spread that sank Shinano in ten hours — the single largest warship ever destroyed by a submarine. A record that still stands after eighty years. 00:00 The failed captain and the ghost ship 11:40 Shinano sails unfinished 23:20 The six-hour surface chase 34:10 Four torpedoes at three-seventeen 47:50 The largest warship ever sunk If your father, grandfather, or family member served on American submarines in the Pacific during World War II, share their name and boat in the comments. These men hunted alone in the dark and changed the course of the war.
