The SSME has a regeneratively cooled nozzle, which would protect the outer surfaces as well as the inner.
What will have to happen is, either they will revert to SSME (i.e., go back to Ares V "Classic" after all) or spend money developing a regeneratively cooled RS-68.
The RS-68 does NOT have a regeneratively cooled diverging nozzle extension, and is protected from the hot exhaust gases on the INSIDE by ablative material.
Both engines are regeneratively cooled, pump fed, LOX-hydrocarbon.
But on Flight 3, with the regeneratively cooled engine, there was some residual thrust after engine shut down and this caused the first stage to be pushed back toward the second stage after separation and there was a recontact between the stages.
That is, we cannot blow any limits doing this - our build out will almost certainly have to be gradual, and probably comparatively slow until the total density of renewables is great enough to power regeneratively.
The Falcon-1 failed, on at least one of its test flights, because fuel left in its regeneratively cooled engine continued to give a small thrust that sent the first stage careening into the second and broke the second stage engine.
Based on the Merlin 1C engine that boosted the SpaceX Falcon 1 rocket to orbit in 2008, the Merlin Vacuum engine uses a regeneratively cooled combustion chamber.
The anticipated performance is made possible by coupling the regeneratively-cooled TR408 RCE with a high area ratio nozzle.
Key advances include an integrated igniter, an electroformed close-out of the regeneratively-cooled chamber, and a large area ratio nozzle.
