As of 2021, the lead vessel of the series is under construction and expected to be commissioned by 2027. In total, it had been planned to build three vessels by 2033. They were planned to be operated by the Russian company FSUE Atomflot which operates Russia's fleet of nuclear-powered icebreakers. However, in February 2023 it was reported that only one Project 10510 vessel would be built before 2035.
