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]

Contents

UB-113 was lost in autumn 1918 for unknown reasons. [2] According to recent sources, SM UB-113 probably crossed paths with the French gunboat l'Engageante on 29 August in the Gulf of Gascony and was sunk. Occasional confusion with the SM UB-123, which also met a mysterious fate, remains.

Construction

She was built by Blohm & Voss of Hamburg and following just under a year of construction, launched at Hamburg on 23 September 1917. 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.
