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 "Arktika" was withdrawn from service in 2008 after clocking up 175,000 hours of reactor operation time and covering more than 1 million nautical miles.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".

is a vessel designed for icebreaking duties on the Great Lakes. "Mackinaw" was home-ported in Cheboygan, Michigan during its active service. Due to "Mackinaw"s age and expensive upkeep, the cutter was decommissioned and replaced with a smaller multipurpose cutter (, which was commissioned in Cheboygan the same day). The old "Mackinaw" moved under its own power on June 21, 2006 from the port of its decommissioning to a permanent berth (at the dock) at the ship's namesake port, Mackinaw City, Michigan, where she now serves as the Icebreaker Mackinaw Maritime Museum.
