German submarine U-2511 was a Type XXI U-boat of Nazi Germany's Kriegsmarine during World War II. The Elektroboot submarine was laid down on 7 July 1944 at the Blohm & Voss yard at Hamburg, launched on 2 September 1944, and commissioned on 29 September 1944 under the command of Korvettenkapitän Adalbert Schnee.
Like all Type XXI U-boats, U-2511 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 length of 8 m (26 ft 3 in), and a draught length of 6.32 m (20 ft 9 in). 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).
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). U-2511 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.
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. 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.
On 14 June 1945 U-2511 was transferred from Bergen, and arrived at Lisahally, Northern Ireland on 21 June for Operation Deadlight. The U-boat was scuttled on 7 January 1946 at 7:40 pm in position Coordinates: . 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', revealing she is largely intact except for a large blast hole caused by the shellfire that sank her.
