The Arktika, a Russian nuclear-powered icebreaker, is the lead vessel of the Project 22220 series. It is the biggest and most powerful icebreaker in the world, designed to operate in extreme Arctic conditions.
Arktika is 173.3 m long and has a maximum width of 34 m. It can operate in shallow Arctic river estuaries and also along the Northern Sea Route. Its draught varies between 9 and 10.5 metres by taking in and discharging ballast water.
It has a nuclear-turbo-electric powertrain. The nuclear power plant has 2 pressurised water reactors powered by 20% enriched Uranium-235 and two turbogenerators.
Its propulsion system includes three 4-bladed propellers driven by electric motors with a total propulsion power of 60 megawatts.
The biggest icebreaker can break 2.8 m or 9 ft thick ice at a speed of 1.5 to 2 knots at full power in deep waters.
