SM U-112

SM U-112 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 naval warfare and took part in the First Battle of the Atlantic. 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.

German Type U 93 submarines were preceded by the shorter Type U 87 submarines. U-112 had a displacement of 798 t when at the surface and 996 t while submerged. She had a total length of 71.55 m, a pressure hull length of 56.05 m, a beam of 6.30 m, a height of 8.25 m, and a draught of 3.76 m. The submarine was powered by two 2400 PS engines for use while surfaced, and two 1200 PS engines for use while submerged. She had two propeller shafts and two 1.70 m propellers. She was capable of operating at depths of up to 50 m.

The submarine had a maximum surface speed of 16.4 kn and a maximum submerged speed of 8.4 kn. When submerged, she could operate for 50 nmi at 5 kn; when surfaced, she could travel 9280 nmi at 8 kn. U-112 was fitted with six 50 cm torpedo tubes (four at the bow and two at the stern), twelve to sixteen torpedoes, one 10.5 cm SK L/45 deck gun, and one 8.8 cm SK L/30 deck gun.
