World War II and the first Enrico Toti
The first Enrico Toti was an Italian submarine of the Balilla class. The boat was laid down on 26 January, 1925 at the Odero-Terni-Orlando Naval Yard, located in, La Spezia. She was one of four in her class, launched on 14 April, 1928 and commissioned on 19 September. Her name pays homage to Major Enrico Toti, a First World War combatant posthumously awarded the Italian Gold Medal. The submarine is notable as being the only Italian submarine to have sunk a Royal Navy submarine, the HMS Triad, during the Second World War.
HMS Triad was a T class submarine of the Royal Navy that had set sail from Malta on 9 October, 1940 under the command of Lieutenant-Commander G.S. Salt. On the night of 15 October, off the Gulf of Taranto, she encountered the Enrico Toti, commanded by Lieutenant-Commander Bandino Bandini, all hands lost.

The boat was laid down on April 15, 1965; launched March 12, 1967; commissioned January 22, 1968 and decommissioned on July 1992. These boats were small and designed as "costal hunter killer" submarines for employment under NATO command in the central Mediterranean. As a result, their size was kept to a minimum and long range was not a requirement- the Totis were small and highly maneuverable with a “teardrop” hull.
