She was launched on 15 September 1944 and commissioned under the command of Oberleutnant zur See Günter Behnisch on 4 October 1944.^[2]^[3]

Design

Like all Type XXIII U-boats, U-2337 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).^[4]

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-2337 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.^[4] This class of U-boat did not carry a deck gun.^[2]

Service history

On 9 May 1945, U-2337 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-2337 was one of 116 selected to take part in Operation Deadlight. U-2337 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′N10°05′W / 56.167°N 10.083°W / 56.167; -10.083 .^[2]
