German submarine U-997 was a Type VIIC/41 U-boat built for Nazi Germany's Kriegsmarine for service during World War II. She was laid down on 7 December 1942 by Blohm & Voss, Hamburg as yard number 197, launched on 18 August 1943 and commissioned on 23 September 1943 under Oberleutnant zur See Hans Lehmann.
Design
Like all Type VIIC/41 U-boats, U-977 had a displacement of Шаблон:Convert when at the surface and Шаблон:Convert while submerged. She had a total length of Шаблон:Convert, a pressure hull length of Шаблон:Convert, a beam of Шаблон:Convert, and a draught of Шаблон:Convert.Шаблон:Sfn The submarine was powered by two Germaniawerft F46 supercharged six-cylinder four-stroke diesel engines producing a total of Шаблон:Convert and two BBC GG UB 720/8 double-acting electric motors producing a total of Шаблон:Convert for use while submerged. The boat was capable of operating at a depth of Шаблон:Convert.Шаблон:Sfn
The submarine had a maximum surface speed of Шаблон:Convert and a submerged speed of Шаблон:Convert. When submerged, the boat could operate for Шаблон:Convert at Шаблон:Convert; when surfaced, she could travel Шаблон:Convert at Шаблон:Convert.Шаблон:Sfn U-997 was fitted with three anti-aircraft guns, five Шаблон:Convert torpedo tubes (four on the bow and one on the stern) and fourteen torpedoes. Its complement was between forty-four and sixty.Шаблон:Sfn
Sensors
Passive sonar
U-997 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).[1] 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). The GHG had 24 hydrophones, the Balkongerät had 48 hydrophones and improved electronics, which enabled more accurate readings to be taken.[2]
