Enrico Tazzoli was one of three Calvi-class submarines built for the Regia Marina (Royal Italian Navy) during the 1930s. Completed in 1936, she played a minor role in the Spanish Civil War of 1936–1939 supporting the Spanish Nationalists. She operated in the Atlantic during the Second World War and was second only to the submarine Leonardo da Vinci as the highest scoring Italian submarine of the conflict. Enrico Tazzoli was converted in 1943 to be a submarine transport for blockade-running between Europe and the Far East. She was lost on her first voyage in this role.
