SM UB-118 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 22 January 1918 as SM UB-118.[Note 1]

UB-118 was surrendered to the Allies at Harwich on 21 November 1918 in accordance with the requirements of the Armistice with Germany. She was allocated to British explosive trials at Falmouth (see UB-86, UB-97, UC-92, UB-106, UB-112 and UB-128), but began to take water while in tow from Devonport to Falmouth, and was therefore sunk by her escort on 21 November 1920.[5]

Construction

She was built by AG Weser of Bremen and following just under a year of construction, launched at Bremen on 13 December 1917. UB-118 was commissioned early the next year under the command of Kptlt. Hermann Arthur Krauß. Like all Type UB III submarines, UB-118 carried 10 torpedoes and was armed with a 8.8 cm (3.46 in) deck gun. UB-118 would carry a crew of up to 3 officers and 31 men and had a cruising range of 7,280 nautical miles (13,480 km; 8,380 mi). UB-118 had a displacement of 512 t (504 long tons) while surfaced and 643 t (633 long tons) when submerged. Her engines enabled her to travel at 13.9 knots (25.7 km/h; 16.0 mph) when surfaced and 7.6 knots (14.1 km/h; 8.7 mph) when submerged.
