Design

German Type IXC/40 submarines were slightly larger than the original Type IXCs. U-805 had a displacement of 1,144 tonnes (1,126 long tons) when at the surface and 1,257 tonnes (1,237 long tons) while submerged.[1] The U-boat had a total length of 76.76 m (251 ft 10 in), a pressure hull length of 58.75 m (192 ft 9 in), a beam of 6.86 m (22 ft 6 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.67 m (15 ft 4 in). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines producing a total of 4,400 metric horsepower (3,240 kW; 4,340 shp) for use while surfaced, two Siemens-Schuckert 2 GU 345/34 double-acting electric motors producing a total of 1,000 shaft horsepower (1,010 PS; 750 kW) for use while submerged. She had two shafts and two 1.92 m (6 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).[1]

The submarine had a maximum surface speed of 18.3 knots (33.9 km/h; 21.1 mph) and a maximum submerged speed of 7.3 knots (13.5 km/h; 8.4 mph).[1] When submerged, the boat could operate for 63 nautical miles (117 km; 72 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 13,850 nautical miles (25,650 km; 15,940 mi) at 10 knots (19 km/h; 12 mph). U-805 was fitted with six 53.3 cm (21 in) torpedo tubes (four fitted at the bow and two at the stern), 22 torpedoes, one 10.5 cm (4.13 in) SK C/32 naval gun, 180 rounds, and a 3.7 cm (1.5 in) Flak M42 as well as two twin 2 cm (0.79 in) C/30 anti-aircraft guns. The boat had a complement of forty-eight.[1]

Service history

U-805 was ordered in April 1941 from DeSchiMAG Seebeckwerft in Geestemünde under the yard number 714. Her keel was laid down on 24 December 1942, and the U-boat was launched the following year sometime in October 1943. In February 1944 she was commissioned into service under the command of Kapitänleutnant Richard Bernardelli (Crew 32) in the 4th U-boat Flotilla. She spent the next year as a training boat with the flotilla, then was transferred to the 33rd U-boat Flotilla and deployed on her one and only war patrol in March 1945. At the end of the war U-805 was operating in the West Atlantic as part of the Seewolf group, when she received orders to make for an Allied port in order to surrender. The U-boat reached Portsmouth, New Hampshire, on 14 May 1945, where the crew surrendered and handed the boat over to the US Navy.

The US Navy took U-805 on several Victory Visits to ports on the east coast of the United States before sinking her off the coast in position 42°32′N 69°37′W on 4 February 1946.[2]
