The first Flight-ready SpaceX Raptor engines have probably been built

In May 2018, SpaceX’s propulsion engineering lead Tom Mueller said that flight-ready Raptor engines were already in work. The Raptor design would have to be completed and manufacturing work was beginning. Elon Musk just said he was really excited about the propulsion system’s advanced design.

Over the next 12 months, dozens of Raptor engines will be built and many will be put into the first BFS and BFR which will begin hop tests.

  1. IMHO getting the desired/projected performance from these engines is the last technical show stopper for the BFR. I hope the testing goes well.

  3. They’ve already been testing prototypes for a while now. Their performance isn’t a mystery. I think the hop tests are more about flight testing them under more realistic conditions and integration testing of the spacecraft.
