German submarine U-470 was a

Second World War. She was a very short-lived vessel, being commissioned in the months following the turning point of the Atlantic campaign and thus into a time in which many U-boats were being lost. The demise of U-470 was especially notable as she was sunk with two of her sisters in a brief melée in the waters of the Western Approaches
.

Design

supercharged diesel engines producing a total of 2,800 to 3,200 metric horsepower (2,060 to 2,350 kW; 2,760 to 3,160 shp) for use while surfaced, two Siemens-Schuckert GU 343/38–8 double-acting electric motors producing a total of 750 metric horsepower (550 kW; 740 shp) for use while submerged. She had two shafts and two 1.23 m (4 ft) propellers. The boat was capable of operating at depths of up to 230 metres (750 ft).[2]

The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a maximum submerged speed of 7.6 knots (14.1 km/h; 8.7 mph).

anti-aircraft gun. The boat had a complement of between forty-four and sixty.[2]

Service history

Built by the Deutsche Werke shipyards in Kiel, U-470 took a long time to complete, not being ready for initial working-up operations until a year after her construction began. She was given to Oberleutnant zur See Günther-Paul Grave, a highly experienced submarine officer, who led her through her training and mechanical trials and readied the boat for her active career, a difficult six month process.[3]

War Patrol

U-470's only war patrol was an unlucky affair.

depth charges

Fate

Over the course of the next several hours, the Liberators attacked the submarine with nearly 30 depth charges. Eventually damage was so severe that an abandon ship order was given. It came too late, as U-470 quickly sank with 46 hands including the captain. Two survivors were picked up. Initially there was a reported 15 survivors in the water, but many of them did not find buoyancy supports and drowned over the next few hours.

Wolfpacks

U-470 took part in one wolfpack, namely:
