The USS Cobia submarine sank 13 ships and rescued seven downed American pilots during World War II. The US Navy submarine is open to the public for tours at the Wisconsin Maritime Museum in Manitowoc.
In 1970, the USS Cobia was turned into a memorial for submariners in Manitowoc, Wisconsin, a town known for the Manitowoc Shipbuilding Company, which built 28 submarines during World War II.
