    I suppose that kind of counts, but Boeing doesn’t make the entire SLS, do they? Just the upper stage?

    As you point out, SLS works fine, it’s just ridiculously expensive.

    Edit: Upper stage is ULA (for now). Boeing makes the core stage, sans engines, which are Shuttle leftovers or Aerojet Rocketdyne in the future. SRBs are also Shuttle leftovers, with Northrop Grumman making new ones. Orion is from Airbus.
