were preceded by the shorter Type VIIB submarines. U-352 had a displacement of when at the surface and while submerged. She had a total length of, a pressure hull length of, a beam of, a height of, and a draught of. The submarine was powered by two Germaniawerft F46 four-stroke, six-cylinder supercharged diesel engines producing a total of for use while surfaced, two AEG GU 460/8–27 double-acting electric motors producing a total of for use while submerged. She had two shafts and two propellers. The boat was capable of operating at depths of up to. The submarine had a maximum surface speed of and a maximum submerged speed of. When submerged, the boat could operate for at ; when surfaced, she could travel at. U-352 was fitted with five torpedo tubes, fourteen torpedoes, one SK C/35 naval gun, 220 rounds, and a C/30 anti-aircraft gun. The boat had a complement of between forty-four and sixty.
U-352 left St. Nazaire, on 7 April 1942, and sailed across the Atlantic to the north-eastern coast of the United States. There on 9 May 1942, she was sunk by depth charges from the U.S. Coast Guard cutter, south of Morehead City, North Carolina, in position. Icarus machine gunned the German submarine when it surfaced, preventing the German crew from manning the deck guns. One survivor reported in 1999, that Icarus departed and then 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.
The wreck of U-352 was discovered south of Morehead City, in 1975, by George Purifoy. She lies in about of water, and sits at a 45-degree list to starboard. The wreck scatter is within a 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 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.
