SM UB-93 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 15 May 1918 as SM UB-93.[nb 1]
UB-93 was surrendered to Britain on 21 November 1918 and broken up in Rochester in 1922.[3]
Construction
She was built by AG Vulcan of Hamburg[2] and following just under a year of construction, launched at Hamburg on 12 April 1918. UB-93 was commissioned later the same year under the command of Oblt Karl Thouret. Like all Type UB III submarines, UB-93 carried 10 torpedoes and was armed with a 10.5 cm (4.13 in) deck gun. UB-93 would carry a crew of up to 3 officer and 31 men and had a cruising range of 7,120 nautical miles (13,190 km).[2] UB-93 had a displacement of 510 t (502 long tons; 562 short tons) while surfaced and 640 t (630 long tons; 705 short tons) when submerged. Her engines enabled her to travel at 13 knots (24 km/h; 15 mph) when surfaced and 7.4 knots (13.7 km/h; 8.5 mph) when submerged.[2]
