Project 10510 Lider
Project 10510 Lider is a nuclear-powered icebreaker operated by Rosatomflot, powered by 2 RITM-400 of about 315 MWt each. Under construction.
120 MW of propulsion, able to break 4.3 metres of ice at 2 knots, intended to make the Northern Sea Route navigable year-round. The lead ship Rossiya was laid down in 2021 for commissioning around 2028, at roughly $2 billion each.

Project 10510 Lider in context
It is one of 5 icebreaker programs on record, 2 of them operating and 2 retired, and one of 13 naval reactor programs from the same country.
Each of its reactors is rated about 315 MWt; across the 5 icebreaker programs with a stated rating the median is 171 MWt, and this one ranks 1st.
With 2 reactors per vessel, the combined thermal rating is about 630 MWt.
It entered service in 2028, -2 years ago; the icebreaker programs on record entered service between 1959 and 2028, and this one is the 5th earliest of 5.
| Measure | Project 10510 Lider | Median of icebreaker programs | Standing |
|---|---|---|---|
| Thermal power per reactor (MWt) | 315 | 171 | 1 of 5 |
| Entered service | 2028 | 1989 | 5 of 5 (earliest first) |
Worked out from the entries on this site only, so a figure compares Project 10510 Lider with what is recorded here, not with everything that exists. An entry with no value for a measure is left out of that measure's ranking and median.
