    Raptor Vacuum (RVac) breaths fire!

    Were talking an engine more powerful than the RS-25 used in the Shuttle and SLS, but smaller.

    This is RVac B, which will be good for orbital & cislunar. RVac C gets an optimized specific impulse (~380) for Mars etc.

    The Starship gets 3 of these, plus 3 sea level Raptors..

    And, as promised, RVac can also fire at sea level o_0

    Super Heavy parts (upper dome, fuel stack, ring stacks), new crane assembly, launch table construction, etc.
