SM UB-83 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 October 1917 as SM UB-83.[Note 1]

UB-83 was sunk on 10 September 1918 by HMS Ophelia off Orkney at 58°28′N 1°50′W / 58.467°N 1.833°W / 58.467; -1.833, all 35 of the crew members died in the event.[2]

Construction[edit]

She was built by AG Weser of Bremen and following just under a year of construction, launched at Bremen on 15 September 1917. UB-83 was commissioned later that same year under the command of Oblt.z.S. Günther Krause. Like all Type UB III submarines, UB-83 carried 10 torpedoes and was armed with a 8.8 cm (3.46 in) deck gun. UB-83 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-83 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.
