Project 22220, also referred to as LK-60Ya, is a Russian designation for three nuclear-powered icebreakers under construction at Baltic Shipyard in Saint Petersburg. Once entering service, the ships of the class will be the largest and most powerful icebreakers ever constructed, surpassing their predecessors, Arktika class nuclear-powered icebreakers.[1]


Sibir under construction at Baltic Shipyard in December 2018

The first ship, Arktika (Russian: Арктика, 'Arktika' meaning "Arctic"), was laid down in November 2013 and is expected to enter service in 2019.[2] Launched on 16 June 2016, the ship will be the world's largest and the most powerful icebreaker surpassing Russian icebreaker 50 Let Pobedy.[3]

The second ship of this class, Sibir (Russian: Сибирь, 'Sibir' meaning "Siberia"), was laid down on 26 May 2015 at Baltic Shipyard.[4] On 1 July 2016, the hull of Sibir, one third of the ship and weighing 3,500 t, was shifted 125 meters (410 ft) to the place of the launched Arktika icebreaker, where construction will be completed. The shift made place for the start of construction of the third hull named Ural (Russian: Урал).[5] Construction of the Ural started on 25 July 2016.[6]

In July 2018, it was announced Russian Defence Ministry intends to place an order for additional two Project 22220 icebreakers by 2019.[7][8] The cost for the two vessels is estimated at RUB100 billion ($US1.5 billion).[9] The order was confirmed in August 2019 when Baltic Shipyard, which was the only bidder for the tender, was awarded the construction of the fourth and fifth icebreakers of the series.[10]

Design and construction[edit]

Project 22220 ships have an overall length of 173 metres (568 ft) and breadth of 34 metres (112 ft). The design draught is 10.5 metres (34 ft) and a minimal operating draught is 8.55 metres (28.1 ft). The dual-draught design will enable ships to operate in both Arctic waters and mouths of polar rivers. The ships have a displacement of 33,540 t,[11] or 25,450 t without ballast.[12]

Project 22220 ships will be equipped with two RITM-200 nuclear reactors, with a thermal capacity of 175 MW each. The propulsion power of this class of ships will be 60 MW which is why this class is sometimes referred as LK-60. The icebreakers have been classified by the Russian Maritime Register of Shipping (RMRS) as the ice class, Icebreaker9. The maximum icebreaking capability of Project 22220 vessels is 3.0 m (9.8 ft). The vessels are intended for the Northern Sea Route along the Russian Arctic coast.[13]


In May 2015, it was also reported that Russia had made a principal decision on the development of the conceptual design for a new nuclear-powered icebreaker, designated as Project 10510 or LK-110Ya. According to Sergey Kirienko, Director General of State Atomic Energy Corporation Rosatom, the new icebreaker could move across the Arctic ice of thickness up to 4.5 metres (15 ft). The new icebreaker will reportedly have the propulsion power of 110 MW.[14] Project 10510 will be capable of ensuring year-round navigability of the Northern Sea Route. The design was expected to be finalized by 2016.[15] The vessel with a 50-meter (160 ft) beam will match large tankers.[12] If built, these 110-megawatt icebreakers would be almost twice as powerful as the 60-megawatt Project 22220 icebreakers that will be, once commissioned, the most powerful icebreakers in the world.
