Nuclear-powered icebreaker
On 17 August 1977, NS "Arktika" ("Arctic") became the first surface ship ever to reach the North Pole. "Arktika" was withdrawn from service in 2008 after clocking up 175,000 hours of reactor operation time and covering more than 1 million nautical miles. Rather than be scrapped, there are calls for her to be converted to a museum ship, like her predecessor "Lenin".
HMS Ontario (1780)
HMS "Ontario" was a British warship that sank in a storm in Lake Ontario on 31 October 1780, during the American Revolutionary War. She was a 22-gun snow, and, at in length, the largest British warship on the Great Lakes at the time. The shipwreck was discovered in 2008 by Jim Kennard and Dan Scoville. "Ontario" was found largely intact and very well preserved in the cold water. Scoville and Kennard assert that "the 80-foot sloop of war is the oldest shipwreck and the only fully intact British warship ever found in the Great Lakes."
