Russia's nuclear icebreaker Rossiya, the largest of its kind, will launch in February 2028, with significant advancements in its reactor technology.
Russia's Leader class nuclear-powered icebreaker, Rossiya, is scheduled for launch in February 2028, as reported by Saint Petersburg's PortNews.
Konstantin Knyazevsky, Deputy Director General for Fleet Construction at Atomflot, stated that the vessel is currently 26.9% complete. He also noted that the development of the RITM-400 reactor plant for propulsion is nearing completion.
In September 2025, Rosatom engineers manufactured the second RITM-400 reactor at ZiO-Podolsk. The Rossiya will be the first Leader class vessel under Project 10510, also known as LK-120Ya.
The keel-laying ceremony took place on July 6, 2020. Rosatom State Corporation serves as the state contractor for the program, with Atomflot as the developer and Zvezda Shipbuilding Complex in Bolshoy Kamen as the sole contractor.
The Rossiya will feature a 120 MW propulsion plant, with key dimensions including a length of 210 meters, a breadth of 47 meters, and a draft of 13 meters. Powered by two RITM-400 reactors, it will be the largest and most powerful icebreaker in the world.
This vessel will be capable of breaking ice up to 4 meters thick and creating a 50-meter-wide channel. It is designed to provide year-round escort for large vessels navigating the Northern Sea Route.
