The first submarine built in Italy
after WWII.


The Enrico Toti was the first submarine built in Italy after WWII.
The Toti submarine class includes three other twin boats: Attilio Bagnolini (S-505), Enrico Dandolo (S-513), and Lazzaro Mocenigo (S-514). Their construction responds to the need of the North Atlantic Treaty to monitor - during the years of the Cold War - the arrival of the Soviet nuclear submarines in the Mediterranean.
The main task of S-506 was to identify and track the presence of submarines in transit through the Strait of Sicily.
For many years - thanks to its small size - it was one of the most difficult vessels to detect with electronic equipment such as sonar.
The construction of the Enrico Toti began in the Summer of 1965 at Italcantieri (now Fincantieri) in Monfalcone.
Launched on March 12, 1967, it was handed over to the Italian Navy in January 1968. In 1997 it made the last in-service trip, escorted by the new class of submarines Sauro.
Officially expelled in 1999, it was donated by the Navy to the Museum.
