SM U-116^{[Note 1]} was a German Type 115 U-boat of the Imperial German Navy built at Schichau-Werke, Danzig. As her sister ship SM U-115, she was never completed and ultimately broken up in Danzig after the Armistice with Germany. Her main engines were used in M/S Adolf Sommerfeld ex SMS Gefion. Both boats had been offered to the IGN free of charge by Schichau in an attempt to gain experience in building submarines (Williamson, 15).
