FYI, SpaceX developed all of their engines in-house[1]. Other American rocket companies use Russian engines and Congress's bill forbidding that going forward has put ULA in a very bad place because Blue Origin's BE-4 engine still is not ready after more than a decade of development.

- bombcar 4y agoAh, then it fits even better. I could have sworn someone had been launching on borrowed Russian engines, but maybe that was Boeing.
- mrguyorama 4y agoI think the story is that Elon wanted russian engines and they snubbed him so he got vindictive, like he does, but this time in a good way.
- njarboe 4y agoHe wanted to buy some Russian rockets to send a greenhouse to Mars, but they did not take him very seriously and quoted very high prices. After that is when he got serious about starting SpaceX.
- MichaelCollins 4y agoULA's (Boeing/Lockheed) Atlas V has been using Russian RD-180 engines, and Orbital Science's Antares has used Russian NK-33 and RD-191 engines. None of these were borrowed though, since they're all single-use only. Only SpaceX lands and reuses their first stage boosters.
