German submarine U-2335 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 20 July 1944 at Deutsche Werft, Hamburg, as yard number 489. She was launched on 31 August 1944 and commissioned under the command of Leutnant zur See Karl-Dietrich Benthin on 27 September 1944.^[2]

Design

Like all Type XXIII U-boats, U-2335 had a displacement of 234 tonnes (230 long tons) when at the surface and 258 tonnes (254 long tons) while submerged. She had a total length of 34.68 m (113 ft 9 in) (o/a), a beam width of 3.02 m (9 ft 11 in) (o/a), and a draught depth of3.66 m (12 ft). The submarine was powered by one MWM six-cylinder RS134S diesel engine providing 575–630 metric horsepower (423–463 kilowatts; 567–621 shaft horsepower), one AEG GU4463-8 double-acting electric motor electric motor providing 580 PS (430 kW; 570 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 194 nautical miles (359 km; 223 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-2335 was fitted with two 53.3 cm (21 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 9 May 1945, U-2335 surrendered at Kristiansand, Norway. She was later transferred to Loch Ryan, Scotland on 29 May 1945. Of the 156 U-boats that eventually surrendered to the Allied forces at the end of the war, U-2335 was one of 116 selected to take part in Operation Deadlight. U-2335 was towed out to be sank on 28 November 1945, by gunfire from the British destroyer HMS Onslow and the Polish destroyer ORP Piorun.^[2]

The wreck now lies at 56°10′N 10°05′W / 56.167°N 10.083°W / 56.167; -10.083.^[2]
