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.
Project 22220 icebreaker
Project 22220 (also referred to as LK-60Ya) is a Russian class of three nuclear-powered icebreakers. Once entering service, the ships of the class will be the largest and most powerful icebreakers ever constructed. As of February 2018, two ships were launched and one is under construction at Baltic Shipyard in Russia.
