Design

Like all Type XXI U-boats, U-3041 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).^[4] 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).^[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).^[4] U-3041 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.^[4]

Service history

On 9 May 1945, U-3041 surrendered at Horten, Norway. She was later transferred to Oslo on 18 May 1945, then to Lisahally, Northern Ireland on 3 June 1945, arriving on 7 June 1945.^[3]

Post war service

The Tripartite Naval Commission allocated U-3041 to the Soviet Union. On 10 December 1945, she arrived in Liepāja, Soviet-occupied Latvia, as British N-class N29. On 13 February 1946, the Soviet Navy allocated her to the Baltic Fleet. She was renamed B-29 on 9 June 1949 then sent to the reserve fleet on 29 December 1955. B-29 was redesignated on 18 January 1956, as a floating submarine battery recharging station PZS-31. She was finally struck from the Soviet Navy on 25 September 1958, and broken up for scrap.^[3]
