German submarine U 352

Design

German Type VIIC submarines were preceded by the shorter Type VIIB submarines. U-352 had a displacement of 769 tonnes (757 long tons) when at the surface and 871 tonnes (857 long tons) while submerged. She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in). The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder 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 AEG GU 460/8–27 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).

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). When submerged, the boat could operate for 80 nautical miles (150 km; 92 mi) at 4 knots (7.4 km/h; 4.6 mph); when surfaced, she could travel 8,500 nautical miles (15,700 km; 9,800 mi) at 10 knots (19 km/h; 12 mph). U-352 was fitted with five 53.3 cm (21 in) torpedo tubes (four fitted at the bow and one at the stern), fourteen torpedoes, one 8.8 cm (3.46 in) SK C/35 naval gun, 220 rounds, and an anti-aircraft gun. The boat had a complement of between forty-four and sixty.

1st patrol

U-352 left Kiel on 15 January 1942, and arrived at Bergen in Norway on the 19th. She left the next day and patrolled south of Iceland without success before sailing to her new home port at Saint-Nazaire in France by 26 February.

2nd patrol

U-352 left St. Nazaire on 7 April 1942 and sailed across the Atlantic to the coast of the north-eastern United States. There on 9 May 1942, she was sunk by depth charges from the U.S. Coast Guard cutter Icarus, south of Morehead City, North Carolina, in position 34°13.67′N 76°33.89′W. The Icarus crew machine gunned the German submariners in the water and departed but returned 45 minutes later to pick up survivors. Fifteen of the crew were lost, but 33 survived and spent the remainder of the war as prisoners.

Wolfpacks

U-352 took part in one wolfpack, namely.

Dive site

U-352 lies in about 115 feet (35 m) of water, and sits at a 45-degree list to starboard. The wreck scatter is within a 100-m radius of location above on a sand bottom. This wreck has become an artificial reef that is heavily populated with Hemanthias vivanus. The site was listed on the National Register of Historic Places in 2015. It is a popular scuba diving spot for advanced divers. A replica of the wreck is on display at the North Carolina Aquarium at Pine Knoll Shores.

Heinz Richter

Heinz Karl Richter, a Maschinengefreiter (equivalent of a Fireman 3rd Class) who survived the sinking and now lives in Canada was interviewed for Discovery Channel's special coverage of U-352. He said that Captain Rathke was obsessed with receiving a Knight's Cross of the Iron Cross medal for sinking 100,000 tonnes-worth of enemy ships. Richter said that the captain's obsession eventually led to recklessness, ultimately resulting in the boat's sinking. Richter also said he was the last man out of the U-boat before it sank; those still on board were already dead, or perished in the boat as it sank.

Survivors

According to documents from the Naval Department, the following are survivors of the sinking:
