The article says they can still use the same tooling.
Small consolation.
This thing is no longer "shuttle derived". (Really, was it ever?)
Sure, as long as it has the SRBs. So, we've moved up to 5-segment
boosters. That doesn't make it no longer Shuttle-derived anymore than
the RSRM development after Challenger was an all-new design (in some
ways, RSRM was a bigger change than 5-segment will be.)
I'd have to disagree with that. The so-called "five-segment SRB" test out
in Utah last year was really just a shuttle four-segment SRB with an extra
segment. The CLV "five-segment SRB" will use a different propellant (HTPB,
vs PBAN), different propellant grain geometry (for different q-shaping),
quite possibly a different nozzle geometry, and definitely a new roll-
control method (whether on the second stage or not... it's not the method
the shuttle uses, which is differential gimballing of two SRBs). It's not
quite an entirely new booster, but I think it's a bigger change than the
RSRM. I'd put it more in a class with the filament-wound boosters for VAFB,
or the subsequent ASRM program.
