U 31 (NATO designation: S 181) is a submarine of the German Navy and with its sister ships of the submarine class 212 A is currently the most modern non-nuclear submarine type in the world.
history
The U 212 A submarine, planned and built in cooperation with Nordseewerke Emden (rear ship → drive) and the Kiel shipyard HDW (front ship), cost around 500 million euros. In addition to the sister ship U 32 , two other submarines of this class were built in Emden and Kiel : U 33 and U 34 . U 32 has been in service since October 2005 and U 33 since June 2006. The U 34 went into service in May 2007.
Due to its fuel cell technology and its stealth outer skin , the submarine is almost undetectable and can also remain under water for up to three weeks. Since the fuel cells generate almost no emissions apart from distilled water , the submarine also has fewer traces of telltale traces in the water (noise, heat, exhaust gases).
The submarine was officially commissioned in Eckernförde on October 19, 2005 together with its sister ship U 32 by Defense Minister Peter Struck in the presence of the fleet commander, Vice Admiral Wolfgang E. Nolting . The new submarines are subordinate to the 1st submarine squadron within the operational flotilla 1 and are stationed in Eckernförde.
In contrast to earlier German submarines, the new class has two decks.
Sponsorship
