Russia announced that it would no longer sell rocket engines to the United States, choking: go to the sky with a broom

Roscosmos has the latest threat to global space sanctions. Roscosmos President Dmitry Rogozin said it would no longer sell Russian-made rocket engines to the United States, adding that “go fly with something else, a broom or something.” While most U.S. rockets should be unaffected, it could still change the way cargo is delivered to the International Space Station.

Since the 1990s, most U.S. defense satellites have relied on Russian-made RD-180 rocket engines to power their launch into space. Resupply of fuel and thrusters for timed maneuvers to propel the International Space Station, and the latest no longer selling rocket engines to the United States, Roscosmos President Dmitry Rogozin added, “(Let them) go fly on broomsticks,” a threat that primarily affects Northrop Grumman, United States P. Grumman and United Launch Alliance (ULA).

United Launch Alliance is composed of Lockheed Martin Space Systems and Boeing Defense Space Security (BDS), which covers some rocket launch services of the US Department of Defense, NASA and other government agencies. ), Delta 2, Delta 4, etc.; Antares, assembled and launched by Northrop Grumman, which regularly sends cargo to the International Space Station for NASA, these rockets In the past, it relied on engines designed and produced by the Russian company NPO Energomash.

However, since the Crimea crisis in 2014, the United States has realized that it must stop buying Russian engines. Specifically, ULA partnered with Blue Origin in 2018 to develop the BE-4 engine, a replacement for the RD-180 engine. , ready for the next-generation Vulcan launch vehicle.

And ULA claims that all Russian-supplied engines are ready for active rockets, and the company’s Decatur, Alabama factory still has about two dozen RD-180 engines in stock, which can last the Optimus 5 launch vehicle by 2025. All tasks, so Roscosmos poses little threat to them, even if Russia does not help repair the RD-180 engine, ULA believes that they have accumulated rich experience and knowledge to solve the problem on their own.

But the Antares launch vehicle assembled by Northrop Grumman could be more affected. Russia had planned to hand over 12 more RD-181 engines between 2022 and 2024, and now the latest threat from Roscosmos may render the company’s rockets unable to fly and deliver cargo to the International Space Station.

However, SpaceX has risen globally with its own Falcon 9 rockets and engines, and local American companies such as Rocket Lab have also gained a firm foothold. Even without the help of Russia, the United States should not be too worried in the future.
