She had a total length of 67.23\u00a0m (220\u00a0ft 7\u00a0in), a pressure hull length of 50.50\u00a0m (165\u00a0ft 8\u00a0in), a beam of 6.20\u00a0m (20\u00a0ft 4\u00a0in), and a draught of 4.74\u00a0m (15\u00a0ft 7\u00a0in). 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\u00a0kW; 2,760 to 3,160\u00a0shp) and two SSW GU 343\/38-8 double-acting electric motors producing a total of 750 metric horsepower (550\u00a0kW; 740\u00a0shp) for use while submerged. The boat was capable of operating at a depth of 250 metres (820\u00a0ft).The submarine had a maximum surface speed of 17.7 knots (32.8\u00a0km\/h; 20.4\u00a0mph) and a submerged speed of 7.6 knots (14.1\u00a0km\/h; 8.7\u00a0mph). When submerged, the boat could operate for 80 nautical miles (150\u00a0km; 92\u00a0mi) at 4 knots (7.4\u00a0km\/h; 4.6\u00a0mph); when surfaced, she could travel 8,500 nautical miles (15,700\u00a0km; 9,800\u00a0mi) at 10 knots (19\u00a0km\/h; 12\u00a0mph).U-1172 was fitted with five 53.3\u00a0cm (21\u00a0in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8\u00a0cm (3.46\u00a0in) SK C\/35 naval gun, (220 rounds), one 3.7\u00a0cm (1.5\u00a0in) Flak M42 and two 2\u00a0cm (0.79\u00a0in) C\/30 anti-aircraft guns. Its complement was between forty-four and sixty.Table of ContentsSensors[edit]Passive sonar[edit]Service history[edit]Summary of raiding history[edit]See also[edit]References[edit]Notes[edit]Citations[edit]Bibliography[edit]Sensors[edit]Passive sonar[edit]U-1172 was one of only ten Type VIIC’s to be fitted with a Balkonger\u00e4t (literally ‘Balcony apparatus or equipment’). The Balkonger\u00e4t was used on U-boats (U-682, U-788, U-799, U-977, U-1021, U-1105, U-1306, U-1307 and U-1308).[4] The Balkonger\u00e4t was standard on the Type XXI and the Type XXIII. Nonetheless, it was also fitted to several Type IXs and one Type X. The Balkonger\u00e4t was an improved version of Gruppenhorchger\u00e4t (GHG) (group listening device). The GHG had 24 hydrophones, the Balkonger\u00e4t had 48 hydrophones and improved electronics, which enabled more accurate readings to be taken.[5]The outside view of the German design of Balconger\u00e4t installed on Type VIIC’sService history[edit]The boat’s service career began on 20 April 1944 with the 8th Training Flotilla, followed by active service with 11th Flotilla on 1 December 1944. U-1172 took part in no wolfpacks. U-1172 was sunk on 27 January 1945 in St Georges Channel by depth charges from British frigates HMS\u00a0Tyler, HMS\u00a0Keats and HMS\u00a0Bligh at 52\u00b024\u2032N 05\u00b042\u2032W\ufeff \/ \ufeff52.400\u00b0N 5.700\u00b0W\ufeff \/ 52.400; -5.700.Summary of raiding history[edit]See also[edit]References[edit]Notes[edit]Citations[edit]^ Helgason, Gu\u00f0mundur. “Type VIIC\/41”.
