German submarine U-3017

German submarine U-3017 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 2 September 1944 at AG Weser, Bremen as yard number 1176. She was launched on 5 November 1944, and commissioned under the command of Oberleutnant zur See Rolf Lindschau on 5 January 1945.

Design
Like all Type XXI U-boats, U-3017 had a displacement of 1621 t when at the surface and 1819 t while submerged. She had a total length of 76.70 m (o/a), a beam of 8 m, and a draught of 6.32 m. The submarine was powered by two MAN SE supercharged six-cylinder M6V40/46KBB diesel engines each providing 4000 PS, two Siemens-Schuckert GU365/30 double-acting electric motors each providing 5000 PS, and two Siemens-Schuckert silent running GV232/28 electric motors each providing 226 PS.

The submarine had a maximum surface speed of 15.6 kn and a submerged speed of 17.2 kn. When running on silent motors the boat could operate at a speed of 6.1 kn. When submerged, the boat could operate at 5 kn for 340 nmi; when surfaced, she could travel 15500 nmi at 10 kn. U-3017 was fitted with six 53.3 cm torpedo tubes in the bow and four 2 cm 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.

Service history
On 9 May 1945, U-3017 surrendered at Horten, Norway, before participating in any war patrols. She was later transferred to Oslo on 18 May 1945, then moved to Lisahally, Northern Ireland on 3 June 1945, arriving on 7 June 1945. U-3017 would be spared, for a time, becoming a British N-class submarine, N41, used for testing and then in November 1949, broken up at Newport, Wales.
