Of course there is 'vectored thrust', but rockets are 'single-use'. It
is easier and simpler to use a computer program to control the power of
the three individual nozzles to get the rocket to point to the direction
you want it to go. Controlling the power is as easy as controlling the
rate of flow of air-fuel mixture through a valve.

Wrong again. It is a bunch more complicated to have three nozzles on
each stage than to have one nozzle per stage. Can you tell me of a
current production rocket that uses three or more nozzles per stage?


Please educate yourself by observing the new Russian RS-28 'Sarmat'
heavy lift ICBM set to replace their 'Satan'. The photo at the bottom of
the page shows it has 4 nozzles:

I accept your apology.


More to that. Please feast your eyes. SpaceX 'Falcon 9' rocket has 9
nozzles:
