In 1997, Moscow and Washington signed an agreement almost a billion dollars on the supply of 101 RD-180 engine. A year and a half ago, the US Congress imposed a ban on their use after 2019, but then canceled it when it became clear that its engines over the next three years in the United States will not be created. Immediately after that, the consortium ULA at the request of the Pentagon has ordered the NGO “Energomash” an additional 20 RD-180.
