"Pimp My Starship." :lol:
I contend that Jefferies intended the Phase II ship to be a true refit. His drawings have some very interesting points in common with his prevous design.
There is a section view showing deck structure that looks almost to have been traced from his original TOS section view -- right down to the turbolift pathways. And the primary hull looks like the original is still inside it. The flat AMT-style lip on the underside begins at just about the point where the old hull diameter ends -- making it look like an extension added on to the old hull. The top surface contour has been reworked to the point where it would require some rebuilding, but the bottom contour looks pretty close to MJ's drawings of the TOS-E. The dorsal and engines are, of course, totally new. The secondary hull is the same length and appears only to have been made fatter about the middle. The interior hangar deck is virtually unchanged from the series.
This was the state of things when MJ left the project. After the transition to a feature motion picture, Jefferies' design was revised by Andy Probert. This is where the continuity was broken when he began scaling the components to get what he perceived as a more pleasing balance. He made a deliberate decision to change it so it couldn't be a true refit, even thought the script said otherwise. Today we are left with no way to truly reconcile the "Refit" with the original ship.
This has always bothered me. As nice as the cosmetic refinements he introduced are (and I think they are great), it wasn't necessary to make it "a whole new ship." Most of us like to think of it as actually being Kirk's original ship, not a whole new vessel with maybe a nut or bolt of the original for old times sake.
I think they should have relooped some of the lines in the Director's Cuts of the various movies:
KIRK: "Scotty, they gave her back to... er-- another ship of the same name to me."
SULU (beaming with pride): "Any chance to go aboard The... er, a ship named Enterprise."
