The construction of the station was previously scheduled to proceed in two phases from 2028 to 2035.
"We are planning to launch the first module in 2027, and the final deployment will take place in 2032," Kozhevnikov said in an interview to Rossiyskaya Gazeta newspaper.
RSC Energia intends to finalize the initial design of the station and present it to Roscosmos in summer 2023, he said, adding that after the execution of all necessary government contracts, the construction may begin in 2024.
"Furthermore, we plan to restore the lost pieces of technologies, which were not used in the construction of the ISS [International Space Station], like control moment gyroscopes or high-capacity power supply. The ISS only has American gyrodynes, and the main power comes from the US's segment, too. But we have domestic production as well," Kozhevnikov said.
It is anticipated that, during the initial deployment phase, the station will function simultaneously with the ISS, he added. The duration of one mission will be up to 240 days, and the station will accommodate a crew of up to six people.
