As a result of various delays and challenges, the cost of the first Project 10510 icebreaker is expected to increase by 40–60% and the delivery of the vessel will slip beyond the December 2027 deadline. In May 2024, the

As traditional icebreaker-led convoys were seen preferable over independently-operating ships, the principal characteristics such as a beam of 40–42 metres (131–138 ft) and capability of breaking up to 3.5 metres (11 ft) thick ice were specified with escorting of large-tonnage vessels in mind.

signed a governmental order allocating 125.57 billion rubles of federal money for financing the construction of the first
Project 10510 icebreaker for Rosatom from 2020 onwards and commissioning it by 2027. Previously, the funding for the construction of the icebreaker had been excluded from the

In the late 2000s, increasing shipping activity in the
Russian Arctic and the prospect of turning the Northern Sea Route into a year-round shortcut between Western Europe and Asia called for the development of more powerful icebreakers. The 110-megawatt icebreaker, now referred to simply as "Leader"

As of 2024, the lead vessel of the series is under construction and expected to be commissioned by 2030, three years after the original planned delivery in 2027. Initially there were plans to build two additional sister ships by 2033, but in
February 2023 it was reported that only one Project 10510

icebreakers, the proposed icebreaking vessels included two distinct nuclear-powered icebreaker designs: a 60-megawatt dual-draft line icebreaker and a 110-megawatt "leader-icebreaker". The latter's primary mission would be to ensure reliable year-round shipping in the
Russian Arctic, including

tonnes year-round along the entire
Northern Sea Route. With a propulsion power of 120 megawatts, the icebreaker would be capable of maintaining an average escort speed of 10–11 knots (19–20 km/h; 12–13 mph) in 2-metre (6.6 ft) ice.

February 2023 it was reported that an update of Russia's arctic strategy provided for only one Project 10510 vessel to be built before 2035. The emphasis will instead shift to two additional Project 22220 icebreakers.
