   > A full-flow staged combustion engine is very complex, and prior to the Raptor only two had been built, neither of which successfully flew on a rocket.

   Isn't the Space shuttle main engine / SLS engine a full-flow staged combustion engine?

      As it said raptor was the first and the SLS engines are way older.

      I think China has made a full flow engine too.
