Project 22220, also known through the Russian type size series designation LK-60Ya,[note 1] is a series of Russian nuclear-powered icebreakers. The lead ship of the class, Arktika, was delivered in 2020 and surpassed the preceding Soviet-built series of nuclear-powered icebreakers as the largest and most powerful icebreaker in the world.[9]

As of January 2024, three Project 22220 icebreakers (Arktika, Sibir and Ural) are in service, fourth (Yakutiya) has been launched, fifth and sixth (Chukotka and Leningrad) have been laid down at Baltic Shipyard in Saint Petersburg, and seventh (Stalingrad) is on order.
