German submarine U-3523 was a

Danzig, as yard number 1668. She was launched on 14 December 1944, and commissioned under the command of Oberleutnant zur See Willi Müller on 23 January 1945.[2]

Design

Like all

kilowatts; 3,900 shaft horsepower), two Siemens-Schuckert GU365/30 double-acting electric motors each providing 5,000 PS (3,700 kW; 4,900 shp), and two Siemens-Schuckert silent running GV232/28 electric motors each providing 226 PS (166 kW; 223 shp).[3]

The submarine had a maximum surface speed of 15.6 knots (28.9 km/h; 18.0 mph) and a submerged speed of 17.2 knots (31.9 km/h; 19.8 mph). When running on silent motors the boat could operate at a speed of 6.1 knots (11.3 km/h; 7.0 mph). When submerged, the boat could operate at 5 knots (9.3 km/h; 5.8 mph) for 340 nautical miles (630 km; 390 mi); when surfaced, she could travel 15,500 nautical miles (28,700 km; 17,800 mi) at 10 knots (19 km/h; 12 mph).

2 cm (0.79 in) C/30 anti-aircraft guns. She could carry twenty-three torpedoes, or seventeen torpedoes and twelve mines. The complement was five officers and fifty-two men.[3]

Sinking

U-3523 had been sailing on the surface with

B-24 Liberator of 86 Squadron/G RAF about 10 nautical miles (19 km; 12 mi) north of Skagen Horn, in the Skagerrak on 6 May 1945. All 58 crewmen were lost.[2]

The wreck was thought to be located at 57°52′N 10°49′E / 57.867°N 10.817°E / 57.867; 10.817,[2] however, in April 2018, it was found by Sea War Museum Jutland, Thyborøn, 9 nautical miles (17 km; 10 mi) further west. The wreck lies at a depth of 123 metres (404 ft). The entire fore part of the boat is buried in the seabed while its stern rises 20 metres (66 ft) above the bottom.[4]
