#Sommergibili u boot series

Its main aim was the construction of identical boats and the start of a collaboration in logistic and life-cycle support for the two navies.

In 1996 a Memorandum of Understanding (MOU) gave the start to the cooperation. The two different requirements were mixed into a common one and, because of significant updates to the design, the designation has been changed to Type 212A since then. The final programme started in 1994 as the two navies of Germany and Italy began working together to design a new conventional submarine, respectively to operate in the shallow and confined waters of the Baltic sea and in the deeper waters of the Mediterranean sea. Initial study started on a Type 209 improved design, with AIP capability, called Type 212.

Type 212 is the first of the only two fuel cell propulsion system equipped submarines ready for series production by 2007, the other being the Project 677 Lada class submarine designed by Russian Rubin Design Bureau.Īt the beginning of the 1990s the German Navy was seeking a replacement for the Type 206 submarines. The system is also said to be vibration-free, extremely quiet and virtually undetectable.

The submarine can operate at high speed on diesel power or switch to the AIP system for silent slow cruising, staying submerged for up to three weeks without surfacing and with no exhaust heat. It features diesel propulsion and an additional air-independent propulsion (AIP) system using Siemens polymer electrolyte membrane (PEM) hydrogen fuel cells. The German Type 212 class, also Italian Todaro class, is a highly advanced design of non-nuclear submarine developed by Howaldtswerke-Deutsche Werft AG (HDW) for the German and Italian Navy.

The UB designation was used for coastal attack U-boats, while the UC designation was reserved for coastal minelaying U-boats. The U designation was generally reserved for ocean-going attack torpedo U-boats. German U-boats used during World War I were divided into three series. Although the first four German U-boats- U-1, U-2, U-3, and U-4-were commissioned before 1910, all four served in a training capacity during the war. There were some 380 U-boats commissioned into the Kaiserliche Marine in the years before and during World War I.
