MOSCOW, March 3. /TASS/. Russia’s State Space Corporation Roscosmos will halt the deliveries of rocket engines to the United States in response to anti-Russia sanctions, Roscosmos Chief Dmitry Rogozin said in an interview with the Rossiya-24 TV Channel on Thursday.
"Today we have made a decision to halt the deliveries of rocket engines produced by NPO Energomash to the United States. Let me remind you that these deliveries had been quite intensive somewhere since the mid-1990s," Rogozin said.
The ban applies to RD-180 engines that are used on US Atlas V launch vehicles as the main propulsion systems and RD-181 thrusters operated as the first stage of Antares rockets, the Roscosmos chief specified.
"As of today, there were plans to deliver an additional 12 RD-181 engines in 2022-2024 and talks were also held with the United States on the delivery of RD-181M engines with improved operational characteristics but we believe that in this situation we can no longer supply the United States with our best engines," the Roscosmos head said.
