SM UB-80 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 8 September 1917 as SM UB-80.[Note 1]
UB-80 was surrendered to Italy in accordance with the requirements of the Armistice with Germany on 26 November 1918 and broken up at La Spezia in May 1919.[3]
She was built by AG Weser of Bremen and following just under a year of construction, launched at Bremen on 4 August 1917. UB-80 was commissioned later that same year under the command of Kptlt. Max Viebeg. Like all Type UB III submarines, UB-80 carried 10 torpedoes and was armed with a 8.8 cm (3.46 in) deck gun. UB-80 would carry a crew of up to 3 officer and 31 men and had a cruising range of 8,180 nautical miles (15,150 km; 9,410 mi). UB-80 had a displacement of 516 t (508 long tons) while surfaced and 647 t (637 long tons) when submerged. Her engines enabled her to travel at 13.4 knots (24.8 km/h; 15.4 mph) when surfaced and 7.5 knots (13.9 km/h; 8.6 mph) when submerged.
