The wreck of the U-352

Above is a video of a group diving on the wreck of the German U boat U-352 which lays off of Morehead City, North Carolina. She was sunk in on her 3rd cruise when she was depth charged by the Coast Guard cutter Icarus. 15 crew members were killed, while 33 escaped the sinking and spent the rest of the war as POWs. During her brief career she neither sunk nor damaged any allied ships.

From the outside it looks smaller than I imagined, although I think only the top 1/3 of it is exposed. the above link gives a brief history of the ship, plus details about diving to it.
