SM UB-112 was a German Type UB III submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. She was commissioned into the German Imperial Navy on 16 April 1918 as SM UB-112.[Note 1]
UB-112 was surrendered to the Allies at Harwich on 24 November 1918 in accordance with the requirements of the Armistice with Germany; she was used for explosives trials off Falmouth on 20 November and 1 December 1920, after which the boat was dumped on Castle Beach. The wreck was sold for scrap to R. Roskelly & Rodgers on 19 April 1921 for £125, but remains survive in situ.[4]
Construction
She was built by Blohm & Voss of Hamburg and following just under a year of construction, launched at Hamburg on 15 September 1917. UB-112 was commissioned in the spring the next year under the command of Kptlt. Wilhelm Rhein. Like all Type UB III submarines, UB-112 carried 10 torpedoes and was armed with a 8.8 cm (3.46 in) deck gun. UB-112 would carry a crew of up to 3 officer and 31 men and had a cruising range of 7,420 nautical miles (13,740 km; 8,540 mi). UB-112 had a displacement of 519 t (511 long tons) while surfaced and 649 t (639 long tons) when submerged. Her engines enabled her to travel at 13.3 knots (24.6 km/h; 15.3 mph) when surfaced and 7.4 knots (13.7 km/h; 8.5 mph) when submerged.
