Old Atlas, know I shouldn't be thinking this but....What would you get if the 1.1D Vac was fired at SL? That F12 is still bugging me. Edit: good place to learn something anyhow.

The regen manifold is visible separately above it, so I know it's not that.

Compare it to the F-1 and the only conclusion is the turbo pump exhaust is pumped into the nozzle.

This would need to remain separate if v1.1 us is going to use the same roll control as v1.0.cheers, Martin

...the lower regen part of the nozzle was tube-wall design...
I could be wrong, been know to happen from time to time.

It seems that both Merlin C and D Vac are solely channel wall.
