The Arktika class is a Russian (former Soviet) class of nuclear powered icebreakers. They 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 clearing shipping lanes north of Siberia as well as for scientific and recreational expeditions to the Arctic.
