Russia's Leader class nuclear-powered icebreaker Rossiya is scheduled for launch in February 2028, reported Saint Petersburg's PortNews.

Konstantin Knyazevsky, Deputy Director General for Fleet Construction at Atomflot, said the vessel is currently 26.9 per cent complete. He added that development of the RITM-400 reactor plant for propulsion is nearing completion.

Rosatom engineers manufactured the second RITM-400 reactor at ZiO-Podolsk in September 2025. The Rossiya will be the first Leader class vessel under Project 10510, also known as LK-120Ya.

The keel-laying ceremony was held on 6 July 2020. Rosatom State Corporation is the state contractor for the programme, with Atomflot as developer and Zvezda Shipbuilding Complex in Bolshoy Kamen as the sole contractor.

The Rossiya will feature a 120 MW propulsion plant, with key particulars including a length of 210 metres, breadth of 47 metres and draft of 13 metres. Powered by two RITM-400 reactors, it will be the largest and most powerful icebreaker in the world.

The vessel will be capable of breaking ice up to 4 metres thick and creating a 50-metre-wide channel. It is designed to provide year-round escort for large vessels navigating the Northern Sea Route.
