This has already been discussed at the Blue Origins update thread....but I think it needs some dedicated thread too.I thought they were thinking of using the BE-3 as a RL-10 replacement?

The only big-scale engine program at BO (that we are aware of) is a HydroLox based. How would this fit the Atlas V?
Big blow for AJR?
Be patient people, rockets are hard.

ULA has been doing some initial feasability studies regarding a methane-based booster engine replacement which would be developed by Blue Origin. This would involve using an entirely different booster core. They are looking at putting the engine on a Delta IV booster core.
They should call it Atlas V v1.1
Would a Delta 4 CBC sized methalox stage provide Heavy class capability with a single core, I wonder without doing any calculations... - Ed Kyle
