A submarine around the streets of Milan

The Enrico Toti submarine: the journey from Sicily to the National Museum of Science and Technology in Milan.

Preparations and journey from Sicily to Cremona

The Toti in Augusta. The vessel being donated by the Italian Navy to the Museum is no longer operational. The time is approaching to face the long journey to Milan. We find ourselves between 2000 and 2001. The rust, together with the seawater and its salt, has left the submarine almost unrecognizable. It needs a makeover before it sets off. The Toti will be partially disassembled, cleared of rust, painted, and reassembled.

It begins. Towed by the tugboat Polifemo, the S-506 submarine sets a course for the Adriatic. Departure from the naval base in Augusta, Syracuse is scheduled for April 4, 2001.

Overall, the journey from Sicily to the Po Delta will be a good 600 miles (over 1,100 kilometers).

Arrival in Chioggia

On April 20, 2001, the Toti arrives in Chioggia, where it will remain for a few days until April 29. This is its final goodbye to saltwater. From now on, the boat will journey through fresh river water.

On May 6, 2001, the citizens of Cremona celebrate its arrival. From the very next day, thousands will flock to see it.

It is the summer of 2005. In a few days, on June 30, the Enrico Toti will continue on its way after a 4-year break. With the help of a motor vessel, it will be transferred to the shipyard to be lightened.

Early July, shipyard. During its operational life as a submarine, the Toti weighed 593 tons. Since it was decommissioned in Sicily, some components have been stripped out. Still, 408.5 tons is too much to tow and transport by road.

The Toti needs to "slim down" to a weight of around 375 tons. Two teams are put to work in the water and on board. The first job is to detach the sail, or tower, labeled number "506". It weighs 4.6 tons.

On July 21, the Toti is transferred from the shipyard to the dock ready to be towed in two days' time.

"A front row seat": after toiling on the seabed in the port of Cremona, the sailors of the Italian Navy's Submarine Operations Group enjoy the show and give a knowing wink to the Toti's propeller.

Goodbye to water. The Enrico Toti says its final farewell to the element that it called home for roughly 30 years, traveling 137,000 miles. Its entry into the Museum signals the beginning of a new life, one spent with visitors.

June-August 2005: the Museum prepares

Meanwhile, the museum is preparing to welcome a guest that weighs 340 tons and is almost four times the size of a bus. The Toti will be located in this area. The aircraft need to be moved!

Bridges are installed for the Toti to rest on. The Museum is ready. All that remains is to await the guest's arrival.

Transportation technology: the convoy

The convoy that traveled from Cremona to Milan was 62 meters long, 5 meters wide, and 7.50 meters high in total. It consisted of 2 motorized trucks (mirror images of one another) and the Toti.

In total, there were 30 axles (15 per truck, with the first 6 motorized), each one independent and steered. Transmission was hydraulic and the trucks had 240 wheels in total (8 per axle).

The underground canals and sewers along the route were protected by steel plates and, in four cases, by actual "mobile bridges" designed by the engineer Maurizio Acito. They were assembled with assistance from the army's Bridge Engineering Corps.

The night is long at six kilometers an hour, but a sign sparks joy.

Dreams of a midsummer sunset. People call it the alien, the airship, the rocket.

This night, too, is coming to an end, and Milan draws ever closer.

The procession comes to a halt. The Enrico Toti, which set off on April 5, 2001 from Augusta, a seaside town in the province of Syracuse, and journeyed through the Ionian and Adriatic Seas, Veneto, and Lombardy, has finally dropped anchor. It lives again at the Museum of Science and Technology in Milan.
