NPO Energomash (part of Roscosmos) has completed testing of the RD-191M engine for the upgraded Angara-A5M launch vehicle, the state corporation's press service reported.
The purpose of the development tests was to confirm the engine's characteristics meet the requirements of the technical specifications. The tests were conducted at Energomash since January. The successful completion of the tests paves the way for the delivery of flight engines.
