The Chemical Automatics Design Bureau (KBKhA, part of NPO Energomash of Roscosmos) has completed a series of bench development firing tests of the new domestic rocket engine RD0124MS. They were successful, the press service of the state corporation said.
Roscosmos noted that bench firing tests are a key stage in the ground testing of a rocket engine before it is installed on a rocket.
It is carried out on a special test bench in conditions as close as possible to real flight.
In 2025, KBKhA handed over a copy of this engine intended for the first flight. Simultaneously with the analysis of the test results, the company is manufacturing new RD0124MS units.
At the end of December, the assembly of the new Russian medium-class Soyuz-5 launch vehicle was successfully completed at the Baikonur Cosmodrome. The rocket and ground equipment are fully ready for the first launch, Roscosmos noted.
