German submarine U-4705 was a Type XXIII U-boat of Nazi Germany's Kriegsmarine during World War II. She was ordered on 7 July 1944, and was laid down on 10 November 1944 at Friedrich Krupp Germaniawerft AG, Kiel, as yard number 947. She was launched on 11 January 1945 and commissioned under the command of Oberleutnant zur See Martin Landt-Hayen on 2 February 1945.[2]
Design
Like all Type XXIII U-boats, U-4705 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-3523 was fitted with two 53.3 cm (21.0 in) torpedo tubes in the bow. She could carry two preloaded torpedos. The complement was 14 — 18 men. [3]This class of U-boat did not carry a deck gun.[2]
Service history
On 3 May 1945, U-4705 was scuttled at Kiel, as part of Operation Regenbogen. The wreck was later raised and broken up.[2]
