The Imperial Japanese Navy started World War II with one of the largest submarine forces in the world. Despite the sinking during the war of several major U.S. warships by Japanese submarines, the Japanese were never able to effectively employ their submarines to any great extent.
Japanese submarines tended to operate alone and were directed toward tactical gains. The United States, in contrast, employed wolf packs, embraced new technology, and engaged in a campaign of strategic submarine warfare.
