Popular accounts often reduce Second World War submarine history to German U-boats in the Atlantic and American boats in the Pacific. British submarines also fought in the Atlantic, North Sea, Mediterranean, Indian Ocean, and Pacific. Italian and Japanese boats operated across several of those waters as well, with different navies emphasizing different designs and missions. Anti-submarine requirements depended on the theatre and enemy submarine force, not on one universal Atlantic model.
