SM UC-15 was a German Type UC I minelayer submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. The U-boat was ordered on 23 November 1914, laid down on 28 January 1915, and was launched on 19 May 1915. She was commissioned into the German Imperial Navy on 28 June 1915 as SM UC-15.[Note 1] Mines laid by UC-15 during her eight patrols are credited with sinking three ships. UC-15 disappeared in November 1916.[1]

Design

[edit]

A Type UC I submarine, UC-15 had a displacement of 168 tonnes (165 long tons) when at the surface and 182 tonnes (179 long tons) while submerged. She had a length overall of 33.99 m (111 ft 6 in), a beam of 3.15 m (10 ft 4 in), and a draught of 3.06 m (10 ft 0 in). The submarine was powered by one Benz six-cylinder, four-stroke diesel engine producing 80 metric horsepower (59 kW; 79 shp), an electric motor producing 175 metric horsepower (129 kW; 173 shp), and one propeller shaft. She was capable of operating at depths of up to 50 metres (160 ft).[3]

The submarine had a maximum surface speed of 6.49 knots (12.02 km/h; 7.47 mph) and a maximum submerged speed of 5.67 knots (10.50 km/h; 6.52 mph). When submerged, she could operate for 50 nautical miles (93 km; 58 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 910 nautical miles (1,690 km; 1,050 mi) at 5 knots (9.3 km/h; 5.8 mph). UC-15 was fitted with six 100-centimetre (39 in) naval mine tubes, twelve UC 120 mines, and one 8 millimetres (0.31 in) machine gun. She was built by AG Weser Bremen and her complement was fourteen crew members.[3]

Loss

[edit]

After completion, UC-15 joined the Constantinople Flotilla and became the flotilla's only minelaying submarine[6] in November 1915, after her sister ship UC-13 was accidentally grounded and subsequently destroyed by her crew. In November 1916, UC-15 was sent on a minelaying mission off the Romanian port of Sulina and never returned, being sunk by her own mines.[7][8] This was probably caused by an encounter with the Romanian torpedo boat Smeul, whose captain surprised a German submarine near Sulina in November 1916, the latter reportedly never returning to her base at Varna. This could only be UC-15, whose systems most likely malfunctioned after being forced to submerge in the shallow waters, upon encountering the Romanian torpedo boat.[9]
