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 "Arktika" was withdrawn from service in 2008 after clocking up 175,000 hours of reactor operation time and covering more than 1 million nautical miles.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".
Jääkarhu
Although sometimes called the largest and most powerful icebreaker in the world by the press in the 1920s, "Jääkarhu" was no match for the Soviet polar icebreakers "Yermak" and "Svyatogor" that had nearly twice the displacement and over twice the power of the Finnish icebreaker. However, as a Baltic escort icebreaker she was considered better than the giants and was often compared with the Soviet icebreaker "Lenin", which was roughly of the same size and was considered a very successful design.
