Northern Sea Route. Russia’s nuclear fleet operator Atomflot (part of Rosatom) started the summer and autumn navigation season on the Northern Sea Route (NSR) as the nuclear-powered icebreaker Vaygach took a three-ship convoy under escort. This is the first east-bound voyage this year to deliver oil products and cargoes to remote areas of the country. Atomflot operates seven nuclear-powered icebreakers on the NSR, with three of them belonging to the Project 22220 (Arktika) series. Another two icebreakers of the Arktika series and an icebreaker of the Project 10510 (Lider) series are under construction, with plans to build more icebreakers of the same design. The fifth icebreaker of the Arktika series, Leningrad, was laid down in 2023. The sixth icebreaker of the same type is planned to be laid down in 2025. Rosatom also intends to build a series of four diesel-powered icebreakers.
