Common Centaur
« on: 02/06/2012 02:35 pm »
This gets discussed a bit, but there isn't a thread devoted to the Common Centaur.

Wouldn't it be great if SpaceX joined ULA in using the Common Centaur, wouldn't that generate some economies of scale?

I think that the biggest problem this would create is a potential failure mode bottleneck that could kill US-indigenous GTO and BEO launches in the event of a failure in Common Centaur.  That has always been a good argument against using CC on both AV and DIV.  It is an even better argument against using it on F9 and/or FH too.

Or a barge strikes a bridge halting both the Atlas and Delta deliveries.

Honestly, I suspect ULA will not begin work on a common upper stage until they have  a higher thrust, high ISP, lower cost replacement for the RL-10 workhorse. A stage that uses between two and six RL-10's can not be cost effective. A new stage with larger tanks that uses a single higher thrust engine may be...

I suspect SpaceX is far too optimistic/arrogant about their own abilities to consider using Common Centaur. The cost of Centaur would kill SpaceX's dream of making a very low cost launch vehicle.
