German submarine U-2340 was a Type XXIII U-boat of Nazi Germany's Kriegsmarine during World War II. She was ordered on 20 September 1943, and was laid down on 18 August 1944 at Deutsche Werft AG, Hamburg, as yard number 494. She was launched on 28 September 1944 and commissioned under the command of Oberleutnant zur See Emil Klusmeier on 16 October 1944.^[2]

Design

Like all Type XXIII U-boats, U-2340 had a displacement of 232 tonnes (228 long tons) when at the surface and 256 tonnes (252 long tons) while submerged. She had a total length of 34.14 m (112 ft 0 in) (o/a), a beam width of 3.02 m (9 ft 11 in) (o/a), and a draught depth of 3.66 m (12 ft 0 in). The submarine was powered by one MWM six-cylinder RS134S diesel engine providing 575 metric horsepower (423 kilowatts; 567 shaft horsepower), one AEG GU4463-8 double-acting electric motor electric motor providing 572 PS (421 kW; 564 shp), and one BBC silent running CCR188 electric motor providing 35 PS (26 kW; 35 shp).^[3]

The submarine had a maximum surface speed of 9.7 knots (18.0 km/h; 11.2 mph) and a submerged speed of 12.5 knots (23.2 km/h; 14.4 mph). When submerged, the boat could operate at 4 knots (7.4 km/h; 4.6 mph) for 202 nautical miles (374 km; 232 mi); when surfaced, she could travel 2,600 nautical miles (4,800 km; 3,000 mi) at 8 knots (15 km/h; 9.2 mph). U-2340 was fitted with two 53.3 cm (21.0 in) torpedo tubes in the bow. She could carry two preloaded torpedoes. The complement was 14 – 18 men.^[3] This class of U-boat did not carry a deck gun.^[2]

Service history

On 30 March 1945, U-2340 was sunk by British bombs at Hamburg. The wreck was later raised and broken up.^[2]
