The German Type 212 class, also Italian Todaro class, is a diesel-electric submarine developed by Howaldtswerke-Deutsche Werft AG (HDW) for the German and Italian navies. It features diesel propulsion and an additional air-independent propulsion (AIP) system using Siemens proton exchange membrane (PEM) compressed hydrogen fuel cells. The submarines 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 with little exhaust heat. The system is also said to be vibration-free, extremely quiet and virtually undetectable.
Wilhelm Bauer is a Type XXI U-boat of Nazi Germany's navy (Kriegsmarine), completed shortly before the end of World War II. It was scuttled at the end of the war, having never gone on patrol. In 1957, it was raised from the seabed off Flensburg Firth, refurbished and recommissioned for use by the West-German Bundesmarine in 1960. Finally retired fully in 1983, it is the only floating example of a Type XXI U-boat. It has been modified to appear in wartime configuration and exhibited at the German Maritime Museum in Bremerhaven, Germany.
The Type 214 is a diesel-electric submarine developed by Howaldtswerke-Deutsche Werft GmbH (HDW). It features diesel propulsion with an air-independent propulsion (AIP) system using Siemens polymer electrolyte membrane (PEM) hydrogen fuel cells. The class is exclusively designed for export market. The submarine class combines the design principles of the Type 209 family and the features of the Type 212A submarines. However, as an export design, it lacks some of the classified technologies of the smaller Type 212, the most important of which is probably the non-magnetic steel hull, which makes the Type 212 submarine difficult to detect using a magnetic anomaly detector.
