9. A Disappointing Tally of Enemy Ships Sunk by American Submarines

Rear Admiral Charles Lockwood, new commander of the US Navy’s Pacific Fleet submarines, sat down in March, 1943, to examine the tally of enemy ships sunk by his men. The figures he found were depressing. The previous year, American submarines had fired off 1442 torpedoes, but only sank 211 Japanese ships that totaled less than 1.3 million tons. The real figures, if he had known them at the time, would have depressed Lockwood even more. After the war, it turned out that Lockwood’s figures were actually wildly optimistic. Analysis of captured Japanese records revealed that in 1942, only 109 enemy ships had been sunk by torpedoes from US submarines. The culprit, as was ultimately revealed – but only after massive resistance from US Navy higher ups – was the Mark 14 Torpedo.
