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] She was surrendered to the Allies at Harwich on 22 November 1918 and later transferred to Pembroke, earmarked for use in experiments. In the event, the boat was sold to M. Lynch and Son on 27 September 1920, and towed to Rochester, Kent, where the diesel engines were removed for use ashore. The hulk was re-sold to Upnor Shipbreaking on 25 October 1922 and broken up.[4]

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 996 tonnes (980 long tons) while submerged.[1] She had a total length of 71.55 m (234 ft 9 in), a pressure hull length of 56.05 m (183 ft 11 in), a beam of 6.30 m (20 ft 8 in), a height of 8.25 m (27 ft 1 in), and a draught of 3.76 m (12 ft 4 in). 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. She had two propeller shafts and two 1.70 m (5 ft 7 in) propellers. She 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, she could operate for 50 nautical miles (93 km; 58 mi) at 5 knots (9.3 km/h; 5.8 mph); when surfaced, she 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 cm (4.1 in) SK L/45 deck gun, and one 8.8 cm (3.5 in) SK L/30 deck gun. She had a complement of thirty-six (thirty-two crew members and four officers).[1]
