V25-class torpedo boat

The V25 class, also known as the Type 1913, was a class of torpedo boats built for the Imperial German Navy and was numerically the largest class ever built for the High Seas Fleet, with 71 ships. The boats grew in size as the programme went on, with lengths of about 78 to 83 metres and designed displacements of 812 to 960 tonnes. Each was driven by a pair of steam turbines made by the yard that built it, with steam from three oil-fired water-tube boilers, and they were the first German torpedo boats to burn only oil, with no provision for coal; their engines were rated at 33.5 to 34.5 knots. AG Vulcan built the first group, V25 to V30, and a number of the later boats, at Stettin and Hamburg, while other boats came from Germaniawerft and Schichau. Thirty-two were sunk in the First World War and 29 were scuttled at Scapa Flow.
