Project 22220 icebreaker
The first ship, ("Арктика" – Arctic), was laid down in November 2013 and is expected to enter service in 2019. Launched on 16 June 2016, the ship will be the world's largest and the most powerful icebreaker surpassing the "50 Let Pobedy".
The second ship of this class, "Sibir" – ("Сибирь" – Siberia), was laid down on 26 May 2015 at Baltic Shipyard. On 1 July 2016, the hull of "Sibir", one third of the ship and weighing 3,500 t, was shifted to the place of the launched "Arktika" icebreaker, where construction will be completed. The shift made place for the start of the construction of the hull of the icebreaker "Ural" – ("Урал" – Ural). Construction of the Ural started on 25 July 2016.
Sisu (1938 icebreaker)
The Finnish Board of Navigation decommissioned "Sisu", now the oldest and smallest icebreaker in the state-owned fleet, in 1974. At the time, Finland had a fleet of nine diesel-electric icebreakers in service and two more under construction. The new icebreakers, which had nearly five times the displacement and more than five times the power of the old "Sisu", were designed to guarantee year-round traffic to all Finnish ports in the Bothnian Bay. The second of these icebreakers was named "Sisu" in 1975.
