Deutsches U-Boot-Museum

Type XXIII
Was a smaller version of the large "Electro-Uboat" (Type XXI), with some 61 Uboats being built until the end of World War II.

The Type XXIII-Uboat "U-2344", which was being raised by East Germany in January 1955 off Heiligendamm, was built at Deutsche Werft at Hamburg since 04th of September 1944 and commissioned on 10th of November 1944. The UBoat sank on 18th of February 1945 in the Baltic Sea North East off Heiligendamm while executing combat training, after it collided with "U-2336", another Type XXIII-UBoat, with 11 deaths and just 3 survivors.

Type: Own design by Volkswerft Stralsund for the East German Navy

A new type of UBoat was to be designed for the East German Navy, which should derive from the documentation of "U-1308" (Project 20 "Stichling") and experiences with Kriegsmarine Type XXIII UBoats. Initial concept was for a coastal submarine with a displacement of about 320 to, to be built by the Volkswerft at Stralsund.

Plans were developed for the construction of 14 new coastal submarines, starting in April 1954 with a preseries "Test UBoat", to be followed by one Uboat every three months. Detailed technical data of the planned UBoats are subject of further research.
