German submarine U-3035 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 11 November 1944 at AG Weser, Bremen as yard number 1194. She was launched on 24 January 1945, and commissioned under the command of Oberleutnant zur See Ernst-August Gerke on 1 March 1945.[2]

Design

[edit]

Like all Type XXI U-boats, U-3035 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).[3] 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).[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).[3] U-3035 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.[3]

Service history

[edit]

On 9 May 1945, U-3035 surrendered at Stavanger, Norway. She was later transferred to Scapa Flow, Scotland on 31 May 1945, arriving on 2 June 1945, then to Lisahally, Northern Ireland on 2 June 1945, arriving on 4 June 1945.[2]

Post war service

[edit]

The Tripartite Naval Commission allocated U-3035 to the Soviet Union. On 14 December 1945, she arrived in Libau, Latvia, as British N-class N28. On 13 February 1946, the Soviet Navy allocated her to the Baltic Fleet. She was renamed B-28 on 9 June 1949 then sent to the reserve fleet on 29 December 1955. B-28 was redesignated on 18 January 1956, as a floating submarine battery recharging station PZS-34. She was finally struck from the Soviet Navy on 25 March 1958, and broken up for scrap.[2]
