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.
Viktor Chernomyrdin (icebreaker)
"Viktor Chernomyrdin" will be long overall and have a maximum moulded beam of . When ballasted to the maximum draught of , her displacement is approximately 22,000 tonnes. However, the vessel can also operate at a reduced draught of in shallow waters. These main dimensions make "Viktor Chernomyrdin" the largest diesel-powered icebreaker in the world, second only to the Russian nuclear-powered icebreakers.
