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 "Arktika" was withdrawn from service in 2008 after clocking up 175,000 hours of reactor operation time and covering more than 1 million nautical miles.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".
Moskva (1959 icebreaker)
Moskva (Russian: "Москва") was a Soviet polar icebreaker and the lead ship of a series of five diesel-electric icebreakers named after major Soviet cities. She was built at Wärtsilä Hietalahti shipyard in Helsinki, Finland, in 1960 and was at the time of her delivery the largest and most powerful non-nuclear icebreaker ever built. Shortly after the dissolution of the Soviet Union, "Moskva" was decommissioned after a long and successful career along the Northern Sea Route and sold for scrap in 1992.
