Stick Second Stage and Delta IV

Has anyone else noticed that the proposed
SRB/SSME "Stick" vehicle has a second stage
diameter that is roughly the same as the
diameter of the Delta IV Common Booster
Core (5.1 meters)? And, by the way, that
the SRB/SSME second stage length seems to
be not much less than the length of a CBC?

Yep. Including ATK.

Coincidence or Cooperation?

I guess the White Elephant second stage diameter is driven by the CEV
diameter and the length is then driven by the propellant required.

Using a Delta IV common booster would save a lot of development work,
but that rather defeats the puropose of the Stick.

Not really. Practically, just about all that would be used on a
Stick/DIV vehicle from the DIV woud be the tanks, payload interface and
some of the plumbing, and even the tanks would be changed (shortened).
Development would still be required, but at least the tooling would be
in place for some of the major hardware.

Hmmmmmm.

"Stick/DIV".

S-DIV.

S-IVD?

Would they name the upper stage Delta V (aka delta-v)?

Not really- it has a lifting capability superior to the Delta 4 heavy
and gets the payload to orbit with a total of only two main engines
being fired (one solid, one liquid) which should boost reliability.

Accidents like that happen a lot in the space industry -- some people think
that Buran looks a lot like the Space Shuttle... :-)

I mean the only purpose of the stick is to provide development work.
Hence White Elephant.

also roughly the same diameter as the Falcon IX from SpaceX!
(yes, okay, fairing diameter, not core, and yes, spacex would probably
not want to work with a NASA integrated upper stage)

But hey--maybe NASA's just looking for commonality across several
providers?
