Type 205 Submarine

The Type 205 was a class of German diesel-electric submarines. They were single-hull vessels optimized for the use in the shallow Baltic Sea. The Type 205 is a direct evolution of the Type 201 class with lengthened hull, new machinery and sensors. The biggest difference though is that ST-52 steel is used for the pressure hull since the Type 201's non-magnetic steel proved to be problematic. Type 206, the follow-on class, finally succeeded with non-magnetic steel hulls.

The Type 205 was in service with the Royal Danish Navy until 2004, in which it was known as Narhvalen-class. The Danish boats differed slightly from the German ones to meet special Danish demands. Responsible for the design and construction was the Ingenieurkontor Lübeck (IKL) headed by Ulrich Gabler.
