German submarine U-2524 was a Type XXI U-boat (one of the "Elektroboote") of Nazi Germany's Kriegsmarine, built for service in World War II. She was ordered on 6 November 1943, and was laid down on 6 September 1944 at the Blohm & Voss yard at Hamburg, as yard number 2524. She was launched on 30 October 1944, and commissioned under the command of Kapitänleutnant Ernst von Witzendorff on 16 January 1945.^[1]

Design

Like all Type XXI U-boats, U-2524 had a displacement of 1,621 tonnes (1,595 long tons) when at the surface and 1,819 tonnes (1,790 long tons) while submerged. She had a total length of 76.70 m (251 ft 8 in) (o/a), a beam of 8 m (26 ft 3 in), and a draught of 6.32 m (20 ft 9 in).^[2] The submarine was powered by two MAN SE supercharged six-cylinder M6V40/46KBB diesel engines each providing 4,000 metric horsepower (2,900 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).^[2]

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] U-2524 was fitted with six 53.3 cm (21.0 in) torpedo tubes in the bow and four 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.^[2]

Service history and fate

U-2524 was commissioned on 16 January 1945 and assigned to the 31st U-boat Flotilla at Hamburg for working up and training.^[1] She had not completed this and had carried out no war patrols before being forced to flee the advancing Allied armies.

Sources vary as to her fate: Kemp and Tarrant report she was attacked on 3 May 1945 by Beaufighters from 236 and 254 Squadrons east of Samso and hit with rocket and cannon fire. Kemp states she was left burning and was seen to explode; Tarrant states she survived but was scuttled later.^[3]^[4] However Niestle states simply that she was scuttled on 3 May 1945, in the Kattegat southeast of the island of Fehmarn.^[5] One man was killed but the rest of the crew survived.^[1]

The wreck is believed to be located at 54°26′N 11°39′E / 54.433°N 11.650°E / 54.433; 11.650.^[5]
