Type 212 Submarine

The Type 212 (also known as the Todaro-class) is a highly advanced diesel-electric submarine class developed in Germany by Howaldtswerke-Deutsche Werft AG (HDW) and currently in service with the German and Italian navies. It features diesel propulsion and an additional air-independent propulsion (AIP) system using Siemens proton exchange membrane (PEM) hydrogen fuel cells. 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. The system is also said to be vibration-free, extremely quiet and virtually undetectable.

The Type 212-class is one of only three 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 and the Victoria-class designed by Canadian Canada Submarine Consortium.
