SM UC-6 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 had been ordered by November 1914 and was launched on 20 June 1915. She was commissioned into the German Imperial Navy on 24 June 1915 as SM UC-6.[Note 1] Mines laid by UC-6 in her 89 patrols were credited with sinking 55 ships.

Design

A German Type UC I submarine, UC-6 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-6 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]

Fate

UC-6 sailed from Zeebrugge on 27 September 1917 to lay mines off the Kentish Knock and did not return. She was later reported by British patrols that strong explosions had occurred in explosive nets laid in the area that same day. Other sources, however, state that UC-6 was destroyed by a British seaplane on 28 September 1917.[10]
