SM UB-48 was a German Type UB III submarine or U-boat in the German Imperial Navy (German: Kaiserliche Marine) during World War I. It was commissioned into the German Imperial Navy on 11 June 1917 as SM UB-48.[nb 1]
The submarine conducted nine patrols and sank 32 ships during the war for a total loss of 104,488 gross register tons (GRT) and one destroyer.[4] It operated as part of the Pola Flotilla and later the II Mediterranean U-boat Flotilla based in Cattaro.[4] UB-48 was one of the most successful u-boats serving in the Mediterranean. The boat was assigned the number U-79 in the Austro-Hungarian Navy.[3] It was scuttled in Pola after the surrender of Austria-Hungary on 28 October 1918.[3]
Construction
UB-48 was ordered by the GIN on 20 May 1916 and built by Blohm & Voss of Hamburg.[2] Following less than a year of construction, it was launched at Hamburg on 6 January 1917. UB-48 was commissioned later that same year under the command of Wolfgang Steinbauer.[4] Like all Type UB III submarines, UB-48 carried 10 torpedoes and was armed with a 8.8 cm (3.46 in) deck gun. UB-48 would carry a crew of up to 3 officer and 31 men and had a cruising range of 9,090 nautical miles (16,830 km).[2] UB-48 had a displacement of 516 t (508 long tons; 569 short tons) while surfaced and 651 t (641 long tons; 718 short 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.[2]
