SM UB-117

SM UB-117 was a German Type UB III submarine (U-boat) of the Imperial German Navy (Kaiserliche Marine) during World War I. She was commissioned on April 14, 1918.

Design and Construction: UB-117 was built by AG Vulcan, Hamburg, as part of the larger Type UB III class of U-boats. These submarines were designed to be more seaworthy and have a greater range than their predecessors, the Type UB II boats. They were equipped with two bow torpedo tubes and one stern torpedo tube, and carried a deck gun for surface engagements. Specific details regarding her dimensions, displacement, and machinery specifications are available in sources relating to Type UB III submarines.

Service History: UB-117 operated primarily in the North Sea and the English Channel, participating in the German submarine campaign against Allied shipping. Her operational history was relatively short, as the war ended in November 1918. The exact number of ships sunk or damaged by UB-117, as well as details of specific engagements, are available in records of U-boat activity during that period. Further research is required to collate a complete list of her victims and any notable encounters.

Fate: Following the Armistice, UB-117 was surrendered to the Allied forces. She was later scuttled, along with many other German U-boats, off the coast of the British Isles as part of the terms of the surrender. The precise location and circumstances of her scuttling are documented in historical records pertaining to the disposal of surrendered German submarines.
