SM U-1 was the first U-boat produced for the Imperial German Navy. The boat was constructed by Germaniawerft in Kiel and was commissioned on 14 December 1906. The main purpose of U-1 was to develop operational experience with submarines and to test new equipment. When World War I began in 1914, U-1 was deemed obsolete and was used for training until 19 February 1919, when it was struck by another vessel while on an exercise. It is now on display at the Deutsches Museum in Munich.
