SM UC-63 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 3 April 1916, and was launched on 6 January 1917. She was commissioned into the German Imperial Navy on 30 January 1917 as SM UC-63.[Note 1] In nine patrols UC-63 was credited with sinking 36 ships, either by torpedo or by mines laid. UC-63 was torpedoed and sunk by HMS E52 off Goodwin Sands on 1 November 1917.[1]

Design[edit]

A German Type UC II submarine, UC-63 had a displacement of 422 tonnes (415 long tons) when at the surface and 504 tonnes (496 long tons) while submerged. She had a length overall of 51.85 m (170 ft 1 in), a beam of 5.22 m (17 ft 2 in), and a draught of 3.67 m (12 ft 0 in). The submarine was powered by two six-cylinder four-stroke diesel engines each producing 300 metric horsepower (220 kW; 300 shp) (a total of 1,000 metric horsepower (740 kW; 990 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 11.9 knots (22.0 km/h; 13.7 mph) and a submerged speed of 7.2 knots (13.3 km/h; 8.3 mph). When submerged, she could operate for 59 nautical miles (109 km; 68 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,000 nautical miles (15,000 km; 9,200 mi) at 7 knots (13 km/h; 8.1 mph). UC-63 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 centimetres (3.5 in) Uk L/30 deck gun. Her complement was twenty-six crew members.[3]
