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.
Jääkarhu
"Jääkarhu" left Rotterdam on 3 March 1926. When the new icebreaker arrived in Finland on 7 March, she was welcomed by a number of icebound ships outside Utö. After "Sampo" had arrived from Hanko with the Minister of Commerce and Industry, Tyko Reinikka, other representatives of the state, and members of the press, the newest and largest state-owned icebreaker demonstrated her power by easily overcoming the notorious pack ice fields surrounding the island and escorting a convoy of three merchant ships to the open seas. After spending her first winter escorting ships in the Gulf of Finland, "Jääkarhu" arrived in Helsinki on 27 April 1926. In July she was drydocked in Liepāja, Latvia, where her bottom was repainted.
