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 "Arktika" was withdrawn from service in 2008 after clocking up 175,000 hours of reactor operation time and covering more than 1 million nautical miles.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".
USNS Maumee (T-AO-149)
From 1968 to 1971, the ship was also used in the Navy's "Operation Deep Freeze II", where it was used to transport fuel supplies to McMurdo Sound (South Pole). It was the largest ship to visit Antarctica, and was led into the ice pack by ice breakers. She eventually was reclassified as a "transport oiler", resulting her redesignation from "T-AO-149" (as an oiler) to "T-AOT-149" (as a transport oiler).
