SM UC-14 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 13 May 1915. She was commissioned into the German Imperial Navy on 5 June 1915 as SM UC-14.^{[Note 1]} Mines laid by UC-14 in her 38 patrols were credited with sinking 16 ships, one of which was the Italian pre-dreadnought battleship Regina Margherita,^[10] which at 13,427 tonnes (13,215 long tons) displacement was one of the largest ships sunk by U-boats during the war.^[11] UC-14 was mined and sunk on 3 October 1917.^[1]

The submarine's wreck was finally located in September 2023^{[citation needed]}

Design

A Type UC I submarine, UC-14 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-14 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.^[3]
