Arktika-class icebreaker
The "Arktika" class is a Russian (former Soviet) class of nuclear-powered icebreakers. Formerly known as "Project 10520 nuclear-powered icebreaker", they were the largest and most powerful icebreakers until the 2016 launch of the ship named Arktika. Ships of the "Arktika" class are owned by the federal government, but were operated by the Murmansk Shipping Company (MSCO) until 2008, when they were transferred to the fully government-owned operator Atomflot. Of the ten civilian nuclear-powered vessels built by Russia (and the Soviet Union), six have been of this type. They are used for escorting merchant ships in the Arctic Ocean north of Siberia as well as for scientific and recreational expeditions to the Arctic.
Admiral Makarov (icebreaker)
Admiral Makarov (Адмирал Макаров) is a large Russian icebreaker operated by the Far East Shipping Company (FESCO). Completed in 1975, she is FESCO's oldest icebreaker. "Admiral Makarov" and her sister ship "Krasin" (1976), are the largest of the four icebreakers in FESCO's fleet. She is named after the Imperial Russian Navy Admiral Stepan Makarov and was one of two icebreakers involved in Operation Breakthrough, an international effort to free three gray whales from pack ice in the Beaufort Sea near Point Barrow in the U.S. state of Alaska in 1988.
