On March 28, according to foreign media reports, when Russia decided to stop selling rocket engines to the United States, Elon Musk, CEO of SpaceX, said in a recent interview that the rd-180 engine made by Russia was "very good" < p > musk also admitted that many American aerospace companies are using Russian engines, including Boeing and Lockheed Martin. Ula, a joint venture between the two companies, relies on the rd-180 engine to power its Atlas V rocket. The Atlas V rocket is planned to be produced by blue origin, but has been delayed several times < p > Musk's remarks came as Russia stopped supplying rocket engines to the United States. Dmitry Rogozin, director of the Russian space agency, previously said: "in this case, we can't supply the best rocket engine in the world to the United States. Let them launch with something else, maybe a broom. I don't know what it is." < p > when musk was asked, "is this dangerous for the United States?" The latter responded: "Boeing and Lockheed Martin have always been very dependent on the Russian rd-180 engine. To be fair, this is a great engine. They hope to get rid of this situation with the blue origin engine in the future. I believe there are Antares with rd-180. Therefore, they will not be able to fly." < p > Antares is a two-stage launch vehicle manufactured by Northrop Grumman, which provides low earth orbit launch capability for payloads weighing up to 8000 kg. The rocket is mainly used for NASA's commercial resupply mission, which is part of the company's contract with NASA < p > earlier, NASA astronaut Peggy Whitson was also worried about the prospect of international cooperation in the aerospace industry in an interview. Whitson discussed the use of Russian engines in the United States. She said she was surprised by the degree of dependence of the United States on Russian rocket engines < p > Whitson said: "we really rely on Russian engines more than I know, more than I thought. I hope to see more rocket engines developed in the United States, which I think is a good thing for us." < p > as for whether SpaceX is at risk due to the suspension of engine sales in Russia, musk said: "at SpaceX, we design and manufacture rocket engines ourselves. Therefore, we don't actually use any Russian parts." (small) < / P > < p >
