It was previously believed that the submarine U-111, which the US Navy sank in 1922, is located on depth of about 500 meters. But she was found at a depth of 120 meters.
A World War I German submarine has been discovered 100 years after it sank off the coast of Virginia. In September, shipwreck researcher and diver Eric Petkovic found the wreck of a submarine with the designation U-111 65 km from the coast. This was reported by National Geographic.
Previously it was believed that the submarine U-111, which the US Navy sank in 1922, was at a depth of about 500 meters, but a diver found it at a depth of 120 meters.
It was the last of the sunken German submarines whose whereabouts remained unknown. Previously, 5 German submarines from the First World War and 8 more that sank during the Second World War were found off the North American continent.
Previously, this submarine was thought to be too deep to track its location. Moreover, in ocean water with a high salt content, the wooden parts of ships and submarines quickly decompose, and the metal rusts. The wooden parts absorb worms and other underwater inhabitants.
Researchers discovered the boat using a drone.
The records obtained were compared with images of the sunken ship, they showed that it was indeed the U-111 submarine.
Additional dives confirmed the find, although the research team is keeping the shipwreck site a secret. More studies are planned next year.
Deep-sea diving poses a number of hazards and requires special equipment. Due to the high pressure underwater, divers have to ascend very slowly to the surface to avoid decompression sickness.
