Tass reported that the ban will apply to RD-180 engines that power US-based United Launch Alliance’s (ULA) Atlas V rockets.
The ban also applies to RD-181 engines that are used on Northrop Grumman’s Antares rockets, according to Russian state media. Those rockets are used to power uncrewed resupply missions to the International Space Station. Northrop Grumman did not immediately respond to requests for comment.
“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.
The US does have other means of getting cargo to and from the space station. SpaceX’s Dragon spacecraft are frequently used for that purpose.
“Let them fly on something else, on their brooms,” Rogozin told a Russian TV station Thursday.
