SM U-1, also known in English as the German Type U 1 submarine, is the first U-boat class of the U-boat series of submarines produced for the German Empire's Imperial German Navy. Only one was built. The U-1 was constructed by Germaniawerft in Kiel and was commissioned on 14 December 1906. When World War I began in 1914, the U-1 was deemed obsolete and was used only for training until 19 February 1919, when it was struck by another vessel while on an exercise.
