The Type 205 was a class of diesel-electric German hunter-killer 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 lengthend 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.

In service with the Danish Navy, the Type 205 is known as Narhvalen class. The Danish boats differ slightly from the German ones to meet special Danish demands.

The German boats have been built by Howaldtswerke, the Danish by The Naval Dockyard, Copenhagen.

Notes:

U1 and U2 have originally built as Type 201 submarines with pressure hulls made of non-magnetic steel, but were rebuilt as Type 205 with new pressure hulls out of normal steels after corrosion problems and small cracks have been detected.
U1 was given back to Nordseewerke and had been used to test an experimental closed-cycle diesel air-independent propulsion system before being scrapped
U11 was transformed to a Type 205A double-hulled boat (the outer hull filled with polystyrene foam to make it unsinkable) and used as torpedo target
U12 was used for sonar trials as Type 205B
