German submarine U-1021 was a Type VIIC/41 U-boat of Nazi Germany's Kriegsmarine during World War II.

Laid down on 6 May 1943 at the Blohm & Voss yard in Hamburg, the submarine was launched on 13 April 1944, and commissioned on 25 May 1944, under the command of Oberleutnant zur See William Holpert.

Design

German Type VIIC/41 submarines were preceded by the heavier Type VIIC submarines. U-1021 had a displacement of Шаблон:Convert when at the surface and Шаблон:Convert while submerged.Шаблон:Sfn She had a total length of Шаблон:Convert, a pressure hull length of Шаблон:Convert, a beam of Шаблон:Convert, a height of Шаблон:Convert, and a draught of Шаблон:Convert. The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of Шаблон:Convert for use while surfaced, two Brown, Boveri & Cie GG UB 720/8 double-acting electric motors producing a total of Шаблон:Convert for use while submerged. She had two shafts and two Шаблон:Convert propellers. The boat was capable of operating at depths of up to Шаблон:Convert.Шаблон:Sfn

The submarine had a maximum surface speed of Шаблон:Convert and a maximum submerged speed of Шаблон:Convert.Шаблон:Sfn When submerged, the boat could operate for Шаблон:Convert at Шаблон:Convert; when surfaced, she could travel Шаблон:Convert at Шаблон:Convert. U-1021 was fitted with five Шаблон:Convert torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one [[8.8 cm SK C/35 naval gun|Шаблон:Convert SK C/35 naval gun]], (220 rounds), one [[3.7 cm Flak 18/36/37/43|Шаблон:Convert Flak M42]] and two [[2 cm FlaK 30|Шаблон:Convert C/30]] anti-aircraft guns. The boat had a complement of between forty-four and sixty.Шаблон:Sfn

Sensors

Passive sonar

U-1021 was one of only ten Type VIIC's to be fitted with a Balkongerät (literally 'Balcony apparatus or equipment'). The Balkongerät was used on U-boats (Шаблон:GS, Шаблон:GS, Шаблон:GS, Шаблон:GS, Шаблон:GS, Шаблон:GS, Шаблон:GS, Шаблон:GS and Шаблон:GS). The Balkongerät was standard on the Type XXI and the Type XXIII. Nonetheless, it was also fitted to several Type IXs and one Type X. The Balkongerät was an improved version of Gruppenhorchgerät (GHG) (group listening device) with double the hydrophones.

Service history

U-1021 served with 31st U-boat Flotilla, a training unit, and later with 11th U-boat Flotilla from 1 December 1944 until its disappearance in March 1945.

Patrol and loss

U-1021 sailed from Bergen on 20 February 1945 and headed for the waters around Land's End.

U-1021 was presumed to have been sunk on 30 March 1945 in The Minch in the Hebrides, by depth charges from the British frigates Шаблон:HMS and Шаблон:HMS.

Discovery

However, the wreck of U-1021 was identified by nautical archaeologist Innes McCartney and historian Axel Niestle in December 2006, Шаблон:Convert off Newquay, Cornwall, at position Шаблон:Coord, close to two other U-boats, Шаблон:GS and Шаблон:GS. Further research by Innes McCartney led to the conclusion that all three submarines were sunk in the Bristol Channel by a deep-trap minefield. Minefield "HW A3", which was fatal to U-1021, was laid by Шаблон:HMS on 3 December 1944.

The attack of 30 March 1945 previously assumed to have sunk U-1021 is now believed to have sunk Шаблон:GS.
