In the Big Stone of Primorsky Krai at the Zvezda shipbuilding complex, construction of the lead large linear atomic icebreaker of project 10510 (LK-120Ya, code "Leader") has begun. The steel cutting ceremony for the icebreaker was held on July 6 at the Zvezda hull production unit.
The contract for the construction of the Leader project’s lead atomic icebreaker, dubbed “Russia,” was signed between the Zvezda shipbuilding complex and the Atomflot FSUE on April 23, 2020. The state customer of the icebreaker is Rosatom State Corporation. The first icebreaker of project 10510 will go into operation in 2027. All three icebreakers of this project should be put into operation before 2033.
As previously reported, in total it is planned to build three icebreakers of the new project. In January of this year, the Russian government allocated 2020 billion rubles from the federal budget for the construction of the lead icebreaker from 2027 to 127,576979. Funds have not yet been found for the construction of two other icebreakers of the series, but there is still time, their laying is scheduled for 2023.
Icebreakers "Leader" will be designed for year-round pilotage of large-tonnage cargo ships along the Northern Sea Route.
According to the project, the total displacement of the new icebreakers will be 71,4 thousand tons with a length of 209 meters, a width of 47,7 meters and a height of 20,3 meters. The ship will receive two RITM-400 nuclear reactors with a capacity of 120 megawatts on propellers and a thermal capacity of 315 megawatts each.
As the developers of the project from the St. Petersburg Iceberg Central Design Bureau stated, the Leader icebreaker will be able to reach speeds of up to 24 knots in clean water and up to 12 knots on ice up to 2 meters thick. The maximum overcome ice thickness is 4 meters. The service life of such an icebreaker is designed for 40 years. The crew is 127 people. The autonomy of the icebreaker in terms of provisions will be 8 months.
