    My understanding is that, in retaliation to US sanctions imposed at the start of the invasion of Ukraine, Russia stopped providing RD-180 rocket engines that were used in the Atlas V. My surprise is that the USA relied on Russian rocket engines to put national security payloads into space.

      The use of Russian engines on the Atlas dates back to a Clinton program after the collapse of the USSR. With the Soviet Union no longer able to pay its rocket scientists, it was thought that it was better that the United States pay them for their expertise rather than some other more hostile government gain access to their knowledge.

        Interesting. Thanks for the info! I love learning about this stuff.

        In case you know - was there some sort of exclusivity agreement the USA had for their Russian rocketry purchases? What would have prevented Russia from sharing their info with whoever they wanted, while still selling to the USA? Or was this agreement guided by political norms? Was the Clinton program named? I’d like to learn more about it.

      Prior to the war, relations between the US and Russia were relatively warm. Specifically, during the Bush War on Terror, Russia and China were active partners and enthusiastic participants in crushing “Radical Islamist Extremism”.

      I suspect you can trace the reliance on Russian rockets back to that period, what with the end of the Shuttle program and a confused path forward between administrations.

      Russian industrial rocketry was both world class and dirt cheap, back during the late '00s.
