Type U 31 was a class of U-boats built during World War I by the Kaiserliche Marine.
Between 1912 and 1915 eleven were built on Germaniawerft in Kiel, amongst these top-three-scoring U-35 with the famous Lothar von Arnauld de la Perière as commander, U-39 with Walter Forstmann and U-38 with Max Valentiner. Together these U-boats sunk more than 1,198,139 gross register tons (GRT).[2]
Later admiral and head of the Abwehr from 1935 to 1944 Wilhelm Canaris also served as commander on two different Type U 31 U-boats. He first took over from Max Valentiner on U-38 and later on U-34.
