Design edit
A German Type UC I submarine, UC-9 had a displacement of 168 tonnes (165 long tons) when at the surface and 183 tonnes (180 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 3.04 m (10 ft). The submarine was powered by one Daimler-Motoren-Gesellschaft six-cylinder, four-stroke diesel engine producing 90 metric horsepower (66 kW; 89 shp), an electric motor producing 175 metric horsepower (129 kW; 173 shp), and one propeller shaft. She was capable of operating at a depth of 50 metres (160 ft).[3]
The submarine had a maximum surface speed of 6.20 knots (11.48 km/h; 7.13 mph) and a maximum submerged speed of 5.22 knots (9.67 km/h; 6.01 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 780 nautical miles (1,440 km; 900 mi) at 5 knots (9.3 km/h; 5.8 mph). UC-9 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 Vulcan Stettin and her complement was fourteen crew members.[3]
