German submarine U-4712 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 3 January 1945 at Friedrich Krupp Germaniawerft AG, Kiel, as yard number 954. She was launched on 1 March 1945 and commissioned under the command of Oberleutnant zur See Karl-Heinz Rohlfing on 3 April 1945.[2]
Design
Like all Type XXIII U-boats, U-4712 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-4712 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 4 May 1945, U-4712 was scuttled at Germaniawerft, Kiel, as part of Operation Regenbogen. The wreck was later raised and broken up.[2]
