SM UC-3 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 28 May 1915. She was commissioned into the German Imperial Navy on 1 June 1915 as UC-3.^[Note 1] Mines laid by UC-3 in her 29 patrols were credited with sinking 22 ships and damaging 2 others. UC-3 was caught in a net, detected by hydrophone, and sunk on 23 April 1916 or mined and sunk on 27 May 1916.^[2]^[1]

Design

A German Type UC I submarine, UC-3 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).^[4]

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-3 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.^[4]

Fate

UC-3 was the first submarine to be detected and sunk using a hydrophone. UC-3's fate have different version: One is on 23 April 1916 she was detected using a hydrophone, trapped in a net, and then quickly sunk after a large explosion.^[2] The ship that sank her was the anti-submarine trawler Cheerio, captained by Thomson.^[8] Another is on 27 May 1916, she got mined and sunk.^[1]
