German submarine U-2511 was a

Blohm & Voss yard at Hamburg, launched on 2 September 1944, and commissioned on 29 September 1944 under the command of Kapitänleutnant Adalbert Schnee.^[1]

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).^[4]

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 23 torpedoes or 17 torpedoes and 12 naval mine. The complement was five officers and 52 men.^[4]

Service history

After training with 31st U-boat Flotilla, U-2511 was transferred to 11th U-boat Flotilla at Bergen, Norway, for front-line service on 15 March 1945.^[1]

U-2511 conducted one patrol. On the evening of 30 April 1945 (coincidentally the date of Hitler's death), U-2511 set out from Bergen, Norway for the Caribbean, but on 4 May Schnee received the end-of-the-war cease-fire order.^[1] The commander of U-2511 claimed the U-boat had a British cruiser in her sights on 4 May when news of the German cease-fire was received. He further claimed she made a practice attack before leaving the scene undetected.^[5]

Fate

On 17 June 1945, U-2511 was transferred from Bergen, and arrived at Londonderry Port on 21 June for Operation Deadlight. The U-boat was sunk on 7 January 1946 at 7:40 pm in position 55°33′N 07°38′W / 55.550°N 7.633°W / 55.550; -7.633.^[1] She was sunk by gunfire after her towing cable parted.

The wreck lies at a depth 69 metres (226 ft). She had been visited by divers at least three times, in 1999 and 2001, and circa 2012 for 'Dig WW2 with Dan Snow',^[6] revealing she is largely intact except for a large blast hole caused by the shellfire that sank her.^[7]
