She was commissioned into the German Imperial Navy on 28 June 1915 as SM UC-15.Mines laid by UC-15 during her eight patrols are credited with sinking 3 ships. UC-15 disappeared in November 1916.

A German 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).

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 centimetres (39 in) 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.
