"The Angara-A5M launch vehicle is planned to be launched approximately at the end of 2024," Sergey Kuznetsov said on Wednesday.
Earlier this month, space industry sources revealed that a test launch of the new Angara-A5 heavy-class carrier rocket had been delayed until 2020. As compared to Angara-A5, the Angara-A5M is a modernized version with a different first-stage engine that will allow it to carry heavier loads.
Earlier this year, Russian President Vladimir Putin said that the Angara-A5M rocket was expected to be launched for the first time in 2025, while the launch of the Angara-A5 rocket was scheduled for 2021.
The Angara family includes several environmentally-friendly carrier rockets of various classes.
