SM U-112[Note 1] was a Type U 93 submarine and one of the 329 submarines serving in the Imperial German Navy in World War I. U-112 was engaged in the naval warfare and took part in the First Battle of the Atlantic. [3]
Design
German Type U 93 submarines were preceded by the shorter Type U 87 submarines. U-112 had a displacement of 798 tonnes (785 long tons) when at the surface and 1,000 tonnes (980 long tons) while submerged.[1] It had a total length of 234 ft 9 in (71.55 m), a pressure hull length of 183 ft 11 in (56.06 m), a beam of 20 ft 8 in (6.30 m), a height of 27 ft 1 in (8.26 m), and a draught of 12 ft 10 in (3.91 m). The submarine was powered by two 2,400 metric horsepower (1,800 kW; 2,400 shp) engines for use while surfaced, and two 1,200 metric horsepower (880 kW; 1,200 shp) engines for use while submerged. It had two propeller shafts and two 1.7 m (5 ft 7 in) propellers. It was capable of operating at depths of up to 50 metres (160 ft).[1]
The submarine had a maximum surface speed of 16.4 knots (30.4 km/h; 18.9 mph) and a maximum submerged speed of 8.4 knots (15.6 km/h; 9.7 mph).[1] When submerged, it could operate for 50 nautical miles (93 km; 58 mi) at 5 knots (9.3 km/h; 5.8 mph); when surfaced, it could travel 9,280 nautical miles (17,190 km; 10,680 mi) at 8 knots (15 km/h; 9.2 mph). U-112 was fitted with six 50 centimetres (20 in) torpedo tubes (four at the bow and two at the stern), twelve to sixteen torpedoes, one 10.5 centimetres (4.1 in) deck machine gun, and one 8.8 centimetres (3.5 in) deck machine gun. It had a complement of thirty-six (thirty-two crew members and four officers).[1]
