SMS V25

SMS V25 was a V25-class torpedo boat of the Imperial German Navy that served during the First World War. The ship was built by AG Vulcan at Stettin in Prussia (now Szczecin in Poland), and was completed in June 1914. The ship was sunk by a British mine on 13 February 1915.

Construction and design
In 1913, the Imperial German Navy placed orders for 12 high-seas torpedo boats, with six each ordered from AG Vulcan (V25–V30) and Schichau-Werke (S31–S36). While the designs built by each shipyard were broadly similar, they differed from each other in detail, and were significantly larger and more capable than the small torpedo boats built for the German Navy in the last two years.

V25 was launched from AG Vulcan's Stettin shipyard on 29 January 1914 and commissioned on 27 June 1914.

V25 was 78.5 m long overall and 77.8 m at the waterline, with a beam of 8.33 m and a draft of 3.63 m. Displacement was 812 t normal and 975 t deep load. Three oil-fired water-tube boilers fed steam to 2 sets of AEG-Vulcan steam turbines rated at 23500 PS, giving a speed of 33.5 kn. 225 t of fuel oil was carried, giving a range of 1080 nmi at 20 kn.

Armament consisted of three 8.8 cm SK L/45 naval guns in single mounts, together with six 50 cm (19.7 in) torpedo tubes with two fixed single tubes forward and 2 twin mounts aft. Up to 24 mines could be carried. The ship had a complement of 83 officers and men.

Service
The newly completed V25 was one of the few modern German torpedo boats in the Baltic suitable for offensive operations on the outbreak of the First World War and was deployed as part of the Baltic coast-defence division. On 7 September V25 took part in a sortie into the Gulf of Bothnia with the cruiser SMS Augsburg which resulted in the sinking of a Russian steamer off Raumo. By October 1914 V25 was part of the 17th Half-flotilla of the High Seas Fleet.

On 14 January 1915, the cruisers SMS Strassburg and SMS Stralsund, escorted by the 9th Torpedo boat Flotilla, including V25, set out to lay a minefield off the Humber. The weather was extremely poor, with the torpedo-boats struggling in the heavy seas, and after V25 collided with sister ship SMS V26 causing minor damage, the destroyers turned back, leaving the two cruisers to carry on unescorted. The minefield claimed a British trawler, Windsor, on 22 January.

On 12 February, five torpedo boats of the 9th Flotilla were deployed to screen minesweeping operations near the Amrum Bank in the North Sea. When V25 did not return from this operation, a search found wreckage north of Helgoland. At the time it was believed that she had been sunk by a British submarine, although in fact, no British submarines were in the vicinity, and V25 had probably been sunk by a British mine. All 79 of her crew were lost, including Korvettenkapitän Paul Jacobi, commanding officer of the 17 Half-flotilla, after whom the destroyer Paul Jacobi was named in the 1930s.
