"On Vostochny [space center]… 2026 — the beginning of flight tests of Angara 5V with a hydrogen stage," Rogozin wrote on Twitter.
The Angara family of space launch vehicles is designed to provide lifting capabilities of between 2 and 40.5 metric tonnes into low Earth orbit.
It has been in development since 1995 and was the first orbit-capable rocket developed by Russia since the fall of the Soviet Union to replace the older Proton-M rockets.
