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 "Arktika" was withdrawn from service in 2008 after clocking up 175,000 hours of reactor operation time and covering more than 1 million nautical miles.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".
CCGS John G. Diefenbaker
"John G. Diefenbaker" is designed to break level ice with a thickness of and with a snow cover at over 3 knots. In terms of icebreaking capability, this ranks her just below the largest Russian nuclear-powered icebreakers. Her operational range at in Sea State 3 is projected to be over and she can operate in ice at full power for 25 days. The logistical endurance of the vessel will be 270 days. The new icebreaker will be able to achieve a maximum speed of about in open water, but her normal cruising speed is around 12 knots.
