German submarine U-1024 was a Type VIIC/41 U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 20 May 1943 by Blohm & Voss, Hamburg as yard number 224, launched on 3 May 1944 and commissioned on 28 June 1944 under Kapitänleutnant Hans-Joachim Gutteck.

Design

Like all Type VIIC/41 U-boats, U-1024 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 of 6.20 m (20 ft 4 in), and a draught of 4.74 m (15 ft 7 in).[3] 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).[3]

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).[3] U-1024 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes or 26 TMA or TMB Naval mines, one 8.8 cm (3.46 in) SK C/35 naval gun, (220 rounds), one 3.7 cm (1.5 in) Flak M42 and two 2 cm (0.79 in) C/30 anti-aircraft guns. Its complement was between forty-four and sixty.[3]

Service history

The boat's service career began on 28 June 1944 with the 31st Training Flotilla, followed by active service with 11th Flotilla on 1 February 1945. U-1024 took part in no wolfpacks. U-1024 was captured on 12 April 1945 in the Irish Sea by British frigates HMS Loch Glendhu and HMS Loch More, at 53°39′N 05°03′W / 53.650°N 5.050°W / 53.650; -5.050, with the loss of nine lives. There were 37 survivors. U-1024 sank the following day while being towed.[4][5][6]
