- adventured 8y agoThe US doesn't buy rockets from Russia, ULA uses the RD-180 engine until the new Blue Origin engine is ready. The ULA rockets are eg Atlas V (uses the RS-180) and Delta IV. The Delta IV rocket and heavy lift variation uses the RS-68 [1] engine, which is US tech. Their new Vulcan rocket will use the Blue Origin engine. SpaceX is certified for critical / national security launches and does not use Russia tech. [1] https://en.wikipedia.org/wiki/RS-68 https://en.wikipedia.org/wiki/RS-68
- geomark 8y agoYeah, I meant rocket engines. I realize there's a lot more to a rocket than just the engines.
- mhh__ 8y agoNot buying but getting people to the ISS is done with russian rockets (i.e. No space shuttle anymore)
