USA: Mysterious Nazi submarine from WWII discovered in Great Lakes

Niagara Falls | Divers from the U.S coast guard took part this morning, in a delicate wreck recovery operation to bring to the surface a Nazi submarine discovered two weeks ago at the bottom of Lake Ontario.

The U-boat was spotted for the first time by amateur scuba divers in late January and they had contacted the authorities.

Archaeologists associated with Niagara University and master divers from the U.S Coast Guard were mobilized on the site to determine what it was, and they soon realized that they were dealing with a German submarine that sank during World War II.

A wreck recovery vessel of the Great Lakes Shipwreck Historical Society was mandated to refloat the ship and bring it back to Niagara Falls, where it must be restored before becoming a museum ship.

The delicate recovery operation took nearly 30 hours to complete, but the submarine was finally brought down on the bank with relative ease.


The divers of the U.S. Coastguard braved the frigid water temperature to go attach cables to the wreck for the recovery operation.

The submarine was identified as the UX-791, a unique experimental German submarine, based on the U-1200 model, and known to have participated in the “Battle of the St. Lawrence”.

It was reported missing in 1943 and was believed to have been sunk near the Canadian coast.

Professor Mark Carpenter, who leads the team of archaeologists, believes that the U-boat could have traveled up the St-Lawrence River, all the way to the Great Lakes, where it intended to disturb the American economy.

A report from the dated from February 1943 suggests, that the ship could have attacked and destroyed three cargo ships and two fishing vessels, even damaging the USS Sable (IX-81), an aircraft carrier of the U.S. Navy that was used for training in the Great Lakes, before finally being sunk by anti-sub grenades launched by a Canadian frigate.

“We have known for a long time that the Nazis had sent some of their U-boats in the St-Lawrence River, but this is the first proof that they actually reached the Great Lakes,” Professor Carpenter told reporters.

“This could explain the mysterious ship disappearances that took place in the region in 1943, and the reported “Battle of Niagara Falls” which had always been dismissed as a collective hallucination caused by fear.”

The restoration of the submarine could take more than two years, but once completed, the museum ship is expected to become one of the major tourist attractions of the region.

  1. whats to say russia is doing the same thing as germany we better look into this or russia could easly shoot nukes at us its something to think about in the future amen

  2. It would have been difficult to travel up the river, the locks were not completed until long after the war. But as for a grave, I doubt it any crew members went down with the boat
    probably scuttled the sub and rowed to shore.

  3. It is important to leave it alone why? IF there are bodies inside will this not allow for the internment of their remains? Understand that I am a Navy Vet and a combat veteran, if it does not bother someone who has been there and done that why is it important to even consider the opinion of those that can only theorize what it is supposed to be, or should be?

    hull ingreat shape for 70 +old boat. looks more russian than german superstructer aft of sail is missing. needs experts to check it out,before any thing else is done to it.

    • Yeah that sail looks very much like and old cold war Soviet sub. *Not a sailor or submariner but I former submarine builder and enthusiast.*

  5. If this sub came up the St Lawrence River, how did it get through the locks?

    • Locks aren’t required to reach Lake Ontario from the St Lawrence River

      There were small canals that went around the St. Lawrence rapids at LaChine but no “locks” and to get through those locks on the smaller cnals they would have had to do it at night with the sub fully surfaced. Those canals were only 7 or 8 feet deep and designed for BARGE traffic only
