SM UC-58 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. The U-boat was ordered on 12 January 1916, laid down on 18 March 1916, and was launched on 21 October 1916. She was commissioned into the German Imperial Navy on 12 March 1917 as SM UC-58.[Note 1] In twelve patrols UC-58 was credited with sinking 24 ships, either by torpedo or by mines laid. UC-58 was surrendered on 24 November 1918 and broken up at Cherbourg in 1921.[1]

Design

A German Type UC II submarine, UC-58 had a displacement of 415 tonnes (408 long tons) when at the surface and 498 tonnes (490 long tons) while submerged. She had a length overall of 50.52 m (165 ft 9 in), a beam of 5.22 m (17 ft 2 in), and a draught of 3.61 m (11 ft 10 in). The submarine was powered by two six-cylinder four-stroke diesel engines each producing 290–300 metric horsepower (210–220 kW; 290–300 shp) (a total of 580–600 metric horsepower (430–440 kW; 570–590 shp)), two electric motors producing 620 metric horsepower (460 kW; 610 shp), and two propeller shafts. She had a dive time of 48 seconds and was capable of operating at a depth of 50 metres (160 ft).[3]

The submarine had a maximum surface speed of 11.6 knots (21.5 km/h; 13.3 mph) and a submerged speed of 7.3 knots (13.5 km/h; 8.4 mph). When submerged, she could operate for 52 nautical miles (96 km; 60 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,660 to 9,450 nautical miles (16,040 to 17,500 km; 9,970 to 10,870 mi) at 7 knots (13 km/h; 8.1 mph). UC-58 was fitted with six 100 centimetres (39 in) mine tubes, eighteen UC 200 mines, three 50 centimetres (20 in) torpedo tubes (one on the stern and two on the bow), seven torpedoes, and one 8.8 cm (3.5 in) Uk L/30 deck gun. Her complement was twenty-six crew members.[3]
