SM UB-25 was a German Type UB II submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. The U-boat was ordered on 30 April 1915 and launched on 9 October 1915. She was commissioned into the German Imperial Navy on 11 December 1915 as SM UB-25. The submarine was lost in a collision with SMS V26 in Kiel harbour on 17 March 1917. She was raised on 22 March 1917 by the salvage ship SMS Vulcan and served on as a training boat until she was surrendered to Britain in accordance with the requirements of the Armistice with Germany on 26 November 1918. UB-25 was finally broken up in Canning Town in 1922.
A German Type UB II submarine, UB-25 had a displacement of 265 tonnes (261 long tons) when at the surface and 291 tonnes (286 long tons) while submerged. She had a total length of 36.13 m (118 ft 6 in), a beam of 4.36 m (14 ft 4 in), and a draught of 3.66 m (12 ft 0 in). The submarine was powered by two Benz six-cylinder diesel engines each producing a total 267 metric horsepower (263 shp; 196 kW), a Siemens-Schuckert electric motor producing 210 kilowatts (280 shp; 290 PS), and one propeller shaft. She was capable of operating at depths of up to 50 metres (160 ft).
The submarine had a maximum surface speed of 8.90 knots (16.48 km/h; 10.24 mph) and a maximum submerged speed of 5.72 knots (10.59 km/h; 6.58 mph). When submerged, she could operate for 45 nautical miles (83 km; 52 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 7,200 nautical miles (13,300 km; 8,300 mi) at 5 knots (9.3 km/h; 5.8 mph). UB-25 was fitted with two 50 centimetres (20 in) torpedo tubes, four torpedoes, and one 5 centimetres (2.0 in) SK L/40 deck gun. She had a complement of twenty-one crew members and two officers and a thirty-second dive time.
