SM U-47 was a Type U-43 submarine of the Imperial German Navy (Kaiserliche Marine.). She engaged in commerce raiding during the First World War.

Career[]

U-47 entered service in early 1916, serving initially with the III Flotilla, and from 27 December 1916 with the Pola Flotilla. Her captain between 14 January and 14 June 1918 was Wilhelm Canaris.

She carried out two war patrols and succeeded in sinking 14 ships for a total of 23,931 gross register tons (GRT). In addition to this she damaged three ships for 9,500 GRT and captured another ship as a prize. Engine troubles meant she could not be used from June 1918, and was finally scuttled at Pula on 28 October 1918 during the evacuation.
