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.

Responsible for the design and construction was the Ingenieurkontor Lübeck (IKL) headed by Ulrich Gabler.

These last two boats were built by the Howaldtswerke, in Denmark at The Naval Dockyard, Copenhagen.
