SM UC-44 was a German Type UC II minelaying submarine or U-boat in the German Imperial Navy (Template:Lang-de) during World War I. The U-boat was ordered on 20 November 1915 and was launched on 10 October 1917. She was commissioned into the German Imperial Navy on 4 November 1916 as SM UC-44.[Note 1] In 6 patrols UC-44 was credited with sinking 29 ships, either by torpedo or by mines laid. UC-44 was sunk by the detonation of one of her own mines off the Irish coast at position 52°07′N 6°59′W / 52.117°N 6.983°W / 52.117; -6.983 on 4 August 1917. UC-44's wreck was raised by the Royal Navy in September 1917 and later broken up.[1]

Design

A German Type UC II submarine, UC-44 had a displacement of 400 tonnes (390 long tons) when at the surface and 480 tonnes (470 long tons) while submerged. She had a length overall of 49.45 m (162 ft 3 in), a beam of 5.22 m (17 ft 2 in), and a draught of 3.68 m (12 ft 1 in). The submarine was powered by two six-cylinder four-stroke diesel engines each producing 260 metric horsepower (190 kW; 260 shp) (a total of 520 metric horsepower (380 kW; 510 shp)), two electric motors producing 460 metric horsepower (340 kW; 450 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 11.7 knots (21.7 km/h; 13.5 mph) and a submerged speed of 6.7 knots (12.4 km/h; 7.7 mph). When submerged, she could operate for 60 nautical miles (110 km; 69 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 9,410 nautical miles (17,430 km; 10,830 mi) at 7 knots (13 km/h; 8.1 mph). UC-44 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]
