Diagram of UB-165

UB-165 was a German Type UB III submarine or U-boat in the Imperial German Navy during World War I. She was ordered on 23 September 1916 and was launched on 24 March 1918. UB-165 was commissioned into the Flanders Flotilla on 4 May 1918 under the command of Kapitänleutnant Karl Vesper.

Design and construction

UB-165 was part of the Type UB III class of submarines, which were designed to be ocean-going attack submarines. These submarines had a displacement of 512 tonnes when surfaced and 643 tonnes when submerged. UB-165 had a total length of 55.3 meters, a beam of 5.8 meters, and a draught of 3.7 meters. She was powered by two diesel engines for surface travel and two electric motors for submerged operations, allowing her to reach speeds of up to 13.9 knots on the surface and 7.6 knots underwater.

The submarine was equipped with six torpedo tubes, four at the bow and two at the stern, and carried a total of ten torpedoes. Additionally, UB-165 was armed with a 8.8 cm deck gun for surface combat.

Service history

UB-165 was commissioned into the Flanders Flotilla, which operated in the North Sea and the English Channel. Her operational history was limited due to the late stage of the war at which she was commissioned. She conducted a few patrols but did not achieve any significant successes before the Armistice of 11 November 1918.

After the war, UB-165 was surrendered to the Allied powers as part of the terms of the armistice. She was eventually broken up for scrap.
