Have any renderings of this combo been produced? Can we assume this configuration would involve no SRBs? Given the past discussion of adding a segment to the crew access tower once Vulcan comes on line, are we correct to assume the new combo will be taller than original configuration on AV.
@JRSFN Vulcan Centaur would require a 422 configure. A Vulcan ACES would need a Vulcan 40X (baseline ACES)
I've seen a render of this configuration. I'll see if I can find it here on NSF.edit:
As for CAT, AR-1 powered Vulcan would require a lift. BE-4 powered Vulcan-Centaur might not. I'm guessing (?) Vulcan-ACES will require changes.
I believe there's a non-trivial possibility that CST-100 will never
fly on Vulcan, especially Vulcan-ACES.
Vulcan cancellation, delays, and/or parallel Atlas V operations could keep CST-100 on Atlas until ISS retirement.
Vulcan-ACES will come online around 2023/2024 when ISS retirement may be imminent. Will there really be a market for LEO transportation services then?
