U-792 was a Type XVIIA U-boat of Nazi Germany's Kriegsmarine during the Second World War. She was one of a small number of U-boats fitted with Hellmuth Walter's high test peroxide propulsion system, which offered a combination of air-independent propulsion and high submerged speeds. She spent the war as a trials vessel and was scuttled on 4 May 1945 in the Audorfer See, near Rendsburg.
The U-792 was laid down on 1 December 1942 at the Blohm & Voss shipyard in Hamburg, Germany. She was launched on 28 September 1943 and commissioned on 16 November 1943 under the command of Oberleutnant zur See Horst Heitz.
When she was completed, the submarine was 39.05 metres (128 ft 1 in) long overall, with a beam of 4.50 metres (14 ft 9 in) and a draught of 4.30 metres (14 ft 1 in). She was assessed at 309 t (304 long tons) submerged. The submarine was powered by one Deutz SAA SM517 supercharged 8-cylinder four-stroke diesel engine producing a total of 210 metric horsepower (150 kW; 210 shp) for use while surfaced and two Walter gas turbines producing a total of 5,000 metric horsepower (3,700 kW; 4,900 shp) for use while submerged. She had one shaft and one 1.23 m (4 ft) propeller. The submarine had a maximum surface speed of 9 knots (17 km/h; 10 mph) and a maximum submerged speed of 25 knots (46 km/h; 29 mph) when submerged, the U-boat could operate for 127 nautical miles (235 km; 146 mi) at 20 knots (37 km/h; 23 mph) and when surfaced, she could travel 1.840 nautical miles (3.408 km; 2.117 mi) at 9 knots (17 km/h; 10 mph).
Service History And End
U-792 did not undertake any combat patrols and was instead assigned as a trials boat at first to the 5th U-boat Flotilla, followed by the 8th U-boat Flotilla, before returning to the 5th flotilla for the rest of the war and was used in March 1945 as a floating fuel bunker. In December 1944, her commander was replaced by Oberleutnant zur See Hans Diederich Duis.
The wreck of U-792 lay at Howaldtswerke in Kiel to be examined. She was first raised as a British prize and used for trials, but was soon torn down for parts and finally scrapped. Her real final fate is still unknown as it is believed that she wasn't scrapped.until 26 May 1945, when she was lifted by the British and taken to the
