SM UB-113 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 25 April 1918 as SM UB-113.[Note 1]

UB-113 was lost in autumn 1918 for unknown reasons.[1] According to recent sources, SM UB-113 has crossed the route of the french gunboat « l'Engageante » on 29 of august 1918 in the Gulf of Gascony and was sunk down. Some confusion remains with the SM UB-123 fate.

UB-113 was commissioned in the spring the next year under the command of Oblt.z.S. Ulrich Pilzecker. Like all Type UB III submarines, UB-113 carried 10 torpedoes and was armed with a 8.8 cm (3.46 in) deck gun. UB-113 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-113 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.
