German submarine U-1017 was a Type VIIC/41 U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 19 April 1943 by Blohm & Voss, Hamburg as yard number 217, launched on 1 March 1944 and commissioned on 13 April 1944 under Kapitänleutnant Victor Graf von Reventlow-Criminil.[4]

Design

Like all Type VIIC/41 U-boats, U-1017 had a displacement of 759 tonnes (747 long tons) when at the surface and 860 tonnes (850 long tons) while submerged. She had a total length of 67.23 m (220 ft 7 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam length of 6.20 m (20 ft 4 in), and a draught length of 4.74 m (15 ft 7 in).[5] The submarine was powered by two Germaniawerft F46 supercharged six-cylinder four-stroke diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) and two BBC GG UB 720/8 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. The boat was capable of operating at a depth of 250 metres (820 ft).[5]

The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a submerged speed of 7.6 knots (14.1 km/h; 8.7 mph). When submerged, the boat could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph).[5] U-1017 was fitted with an 8.8 centimetres (3.5 in) SK C/35 naval gun and 220 rounds, an anti-aircraft gun, five 53.3 cm (21 in) torpedo tubes (four on the bow and one on the stern) and fourteen torpedoes. Its complement was between forty-four and sixty.[5]

Service History

The boat's service career began on 13 April 1944 with the 31st Training Flotilla, followed by active service with 11th Flotilla on 1 November 1944. U-1017 took part in no wolfpacks U-1017 was sunk by depth charges and a FIDO homing torpedo dropped by a RAF Liberator bomber of 120 Squadron on 29 April 1945 in the North Atlantic, NW of Ireland in position Lua error in package.lua at line 80: module 'strict' not found..
