German submarine U-847 was a long-range Type IXD2 U-boat built for Nazi Germany's Kriegsmarine during World War II. Laid down in Bremen and launched on 5 September 1942.

Design

German Type IXD2 submarines were considerably larger than the original Type IXs. U-847 had a displacement of 1,610 tonnes (1,580 long tons) when at the surface and 1,799 tonnes (1,771 long tons) while submerged.^[3] The U-boat had a total length of 87.58 m (287 ft 4 in), a pressure hull length of 68.50 m (224 ft 9 in), a beam of 7.50 m (24 ft 7 in), a height of 10.20 m (33 ft 6 in), and a draught of 5.35 m (17 ft 7 in). The submarine was powered by two MAN M 9 V 40/46 supercharged four-stroke, nine-cylinder diesel engines plus two MWM RS34.5S six-cylinder four-stroke diesel engines for cruising, producing a total of 9,000 metric horsepower (6,620 kW; 8,880 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 1.85 m (6 ft) propellers. The boat was capable of operating at depths of up to 200 metres (660 ft).^[3]

The submarine had a maximum surface speed of 20.8 knots (38.5 km/h; 23.9 mph) and a maximum submerged speed of 6.9 knots (12.8 km/h; 7.9 mph).^[3] When submerged, the boat could operate for 121 nautical miles (224 km; 139 mi) at 2 knots (3.7 km/h; 2.3 mph); when surfaced, she could travel 12,750 nautical miles (23,610 km; 14,670 mi) at 10 knots (19 km/h; 12 mph). U-847 was fitted with six 53.3 cm (21 in) torpedo tubes (four fitted at the bow and two at the stern), 24 torpedoes, one 10.5 cm (4.13 in) SK C/32 naval gun, 150 rounds, and a 3.7 cm (1.5 in) with 2575 rounds as well as two 2 cm (0.79 in) anti-aircraft guns with 8100 rounds. The boat had a complement of fifty-five.^[3]

Service history

She was commanded for her short career by four Knight’s Cross recipients, each a U-boat ace in their own right, although she neither sank nor damaged any vessels. They were:

Kapitänleutnant Friedrich Guggenberger
Korvettenkapitän Wilhelm Rollmann
Kapitänleutnant Jost Metzler
Kapitänleutnant Herbert Kuppisch

She joined 4th Flotilla for training on 23 January 1943, where she remained until 30 June 1943. She then joined 12th Flotilla for active service until 27 August 1943 when she was sunk while providing logistical support for other u-boats operating in the area.

Fate

U-847 was sunk by air-launched FIDO torpedoes dropped from US Avenger and Wildcat aircraft operating from the escort carrier USS Card on 27 August 1943 in the Atlantic Ocean at position 28°19′N 37°58′W / 28.317°N 37.967°W / 28.317; -37.967. All 63 hands were lost.
