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 "Arktika" was withdrawn from service in 2008 after clocking up 175,000 hours of reactor operation time and covering more than 1 million nautical miles.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 D'Iberville
In 1972, "D'Iberville" was one of three icebreaking escorts for a convoy of cargo ships travelling to Mokka Fjord and Eureka. This was the largest convoy to travel that far north into Canada's Arctic. In 1976, in conjunction with , "D'Iberville" travelled into the Northwest Passage to aid after the small icebreaker damaged both her propellers. In 1981, "D'Iberville" made her last Arctic voyage. The ship was decommissioned in 1983. The vessel was laid up first at Quebec City, then at Sorel. Renamed "Phillip O'Hara" in 1984 and back to "D'Iberville" in 1988, the icebreaker was sold for scrap in 1989 and broken up at Kaoshiung, Taiwan.
