Elon’s explanation about the number of engines being so large was evasive.
“We felt comfortable with 9 engines so why not 42”?
Indeed why not 150 ;-)? A bit further he states, the transports to a colony
on Mars would become much larger still.
Raptor is presumably designed for something other than the ITS,
probably the follow-on to Falcon 9.
A yet-to-be-unveiled 3 or 4x Falcon 9 core with nine Raptor engines
would be a straightforward extension of their current business plan,
and it would let a real business eat the cost of developing an engine
for the ITS. Raptor is also much closer to SpaceX’s state of the art
than a hypothetical monster engine that would enable the ITS with nine
or fewer nozzles. And there would be no obvious other use for the
monster engine.
