Enrico Toti SSK
The Enrico Toti, launched on 12 March 1967, was the first submarine built in post-war Italy. In a few years, three more submersibles followed: Dandolo, Mocenigo and Bagnolini, rounding out the Toti class. The class derives its name from the first of the series. Confirming the reliability of the design, all four remained in active service almost thirty years, until the late 1990s.
In 1968 the Mediterranean represented a crucial theater of confrontation between boc; Soviet warships were plying the Mediterranean Sea, penetrating from Gibraltar and from bases on the Black Sea. In this situation Italy occupied a strategic position, and the enhancement of its submarine fleet took on more and more importance. Until that time Italy was using ex-American submarines. The clauses of the peace treaty prohibited Italy, as a defeated Axis power, from building new ones.
The "Toti" Class submarines marked a turning point of some importance in the history of Italian underwater weapons. They were designed and built by Italcantieri, an establishments in Monfalcone, whose work force during the period 1944-45, had obtained experience in the construction of some German type XXI and XXIII submarines. The boats adopted the schnorkel and were equipped with all the facilities and equipment, the experience of wartime and postwar technology had helped improve, achieving remarkable results with regard to silence, at speed underwater, autonomy and operational dimension of immersion.
The Toti is an SSK (Submarine-Killer Submarine), a submarine designed to destroy other ships. The Toti class consisted of small boats, suited to the Mediterranean, and characterized by advanced technical systems (wire-guided torpedoes with autocercante header). For a submarine Hunter as the Toti, the "eyes" were essential: a device capable of emitting and receiving ultrasonic waves to locate underwater objects. The duration of the missions average for these submarines was 14-16 days. These boats had a good set of sensors, communication systems and electronic warfare.
The armament was 4 bow torpedo tubes for launching torpedoes anti-ship-anti-submarine warfare multi-role A184 to wire-Guide and head to a subservient autocercante launch Central electronics, produced and designed by Fiat Mirafiori. Initially they were also provided with 12 mines. The boats were fully welded single hull, which included torpedo tubes and bow and aft ballast boxes. The five-bladed propeller was driven only by the electric motor, powered by batteries and submerged by generators in emergence.
Entering service in 1968-69, the "Toti" were assigned initially to the base of La Spezia to be transferred since 1971 to Augusta, framed in the 2nd Submarine Group (GRUPSOM2) of Submarine Command. The limited armament and autonomy limited to medium-short missions autonomy meant that the Navy soon moved to larger and more efficient, although apparently less popular, Sauro class submarine, to which were transferred experiences and specialties of vessels of "Toti" class. At the end of the cold war these submarines were used only in training.
Of the four units, three were preserved as museum ships: The Dandolo is kept at l'Arsenale di Venezia, while the Toti is preserved at Museo nazionale della scienza e della tecnologia "Leonardo da Vinci" in Milan. A similar solution was found for the Mocenigo in the port of Augusta.
