Wednesday, 25 January, “Kommersant” with reference to several top-managers of enterprises of the space industry reported that the leadership of the Roscosmos withdrew in VMZ all the engines of the second and third stages of the carrier rockets “proton-M”, released in the last few years. According to interlocutors of the edition, the reason for this decision was the technological problems that are discovered during testing of one of the liquid engines of the second stage of the launch vehicle.

In particular, it was found that during the Assembly of engines is materials using precious metals used “non-liquid components”, which turned out to be less heat resistant. According to the publication, the situation caught the interest of the FSB and the Investigative Committee, who are trying to understand how was the replacement of material, if the documents are all the engines in order.
