The LK-60Ya class (Russian: ЛК-60Я) is a Russian class of three nuclear-powered icebreakers. Formerly known as Project 22220, once enter in service the ships of the class will be the largest and most powerful icebreakers ever constructed.[1] As of February 2018, two ships were launched and one is under construction at Baltic Shipyard in Russia.


The first ship, Arktika (Арктика – 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 the 50 Let Pobedy.[3]

The second ship of this class, Sibir – (Сибирь – 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 the construction of the hull of the icebreaker Ural – (Урал – Ural).[5] Construction of the Ural started on 25 July 2016.[6]

Design and construction[edit]

LK-60Ya-class 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. LK-60Ya ships have a displacement of 33,540 t,[7] or 25,450 t without ballast.[8]

LK-60Ya 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. LK-60Ya has been classified by the Russian Maritime Register of Shipping (RMRS) as the ice class, Icebreaker9. The maximum icebreaking capability of LK-60Ya-class vessels is 3.0 m (9.8 ft). The vessels are intended for the Northern Sea Route along the Russian Arctic coast.

Next generation[edit]

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. 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.[9] If built this new icebreaker would be almost twice as powerful as the LK-60Ya-class icebreakers. The LK-110Ya-class nuclear icebreaker (ЛК-110Я [ru]) will be capable of ensuring year-round navigability of the Northern Sea Route. The design is expected to be finalized by 2016.[10] The vessel with a 50-meter (160 ft) beam will match large tankers.[8]
