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 "Arktika" was withdrawn from service in 2008 after clocking up 175,000 hours of reactor operation time and covering more than 1 million nautical miles.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".
Project 22220 icebreaker
Project 22220 (also referred to as LK-60Ya) is a Russian class of three nuclear-powered icebreakers. Once entering service, the ships of the class will be the largest and most powerful icebreakers ever constructed. As of February 2018, two ships were launched and one is under construction at Baltic Shipyard in Russia.
