Roscosmos recall all engines of the second and third stages of the carrier rockets “proton-M” units manufactured by the Voronezh mechanical factory (VMZ), have not been technological to the test during the fire tests. About it reports “Tape.ru” with reference to sources in the Russian rocket and space industry.
Problems during testing were identified in the RD-and RD 0210/0211-0213/0214 installed on the second and third stage of the rocket “proton-M”, respectively.
