Italian submarine Enrico Toti (S 506) was the first of a new class of Italian submarine (Toti-class), with the S 506 Enrico Toti being laid down in 1965, launched in 1967, decommissioned in 1992 and preserved as a museum ship in Museo della Scienza e della Tecnologia "Leonardo da Vinci", in Milan. The ship, and class, are named after the Italian Enrico Toti.
Toti was built by Fincantieri in Monfalcone, between 1965 and 1967, and given to the Italian Navy in 1968; Soon after that three more identical units were added to what is called the "classe Toti". They are small submarines (so small that they were called “pocket sized submarines”), employed from the late 1960s until the end of the 90s. They were conceived to work inside the Mediterranean sea and have never had to face real war situations. They had two main tasks:
- patrol the Mediterranean sea with special attention to the Channel of Sicily during the Cold War; for this reason their main base was the Military Arsenal of Augusta (Syracuse);
- participate in NATO exercises with other submarines (US).
The Enrico Toti arrived at the Museo della Scienza e della Tecnologia "Leonardo da Vinci" in August 2005 with a trip in two steps:
- 2001: From Augusta to the Cremona port, towed through the Adriatic sea and the Po (14 days)
- 2005: From Cremona to Milan, on top of a specially built convoy, on a road trip lasting four nights.
As museum ship the Toti is unusual, because Milan has no direct access to the sea or a significant river. Moreover, the museum is in the inner part of the city. The transportation of the sub to the museum was made overnight in mid-August, to minimize inconvenience to the population.
Recently, a stray female cat was found near the museum and personnel brought her in the Toti, where she lives and is called "the last captain of the Toti".
In 2016, the Italian telephonic company TIM filmed a TV spot with people dancing, including Santa Claus on a beach, some Star Wars First Order Stormtroopers, an astronaut with an Apollo/Skylab A7L spacesuit on the Moon and two sailors on the harbour mole-like entrance of the museum ship.
