SM UB-51 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 Pola Flotilla of the German Imperial Navy on 26 July 1917 as SM UB-51.[Note 1]
She operated as part of the Pola Flotilla based in Cattaro. UB-51 was surrendered 16 January 1919 with the remainder of the Pola Flotilla following orders by Admiral Reinhard Scheer to return to port. UB-51 was later broken up at Swansea.[1]
Construction
UB-51 was ordered by the GIN on 20 May 1916. She was built by Blohm & Voss, Hamburg and following just under a year of construction, launched at Hamburg on 8 March 1917. UB-51 was commissioned later that same year under the command of Kptlt. Ernst Krafft. Like all Type UB III submarines, UB-51 carried 10 torpedoes and was armed with a 8.8 cm (3.46 in) deck gun. UB-51 would carry a crew of up to 3 officer and 31 men and had a cruising range of 9,040 nautical miles (16,740 km; 10,400 mi). UB-51 had a displacement of 516 t (508 long tons) while surfaced and 651 t (641 long tons) when submerged. Her engines enabled her to travel at 13.6 knots (25.2 km/h; 15.7 mph) when surfaced and 8 knots (15 km/h; 9.2 mph) when submerged.
