She would HAVE to have the registry, the moment they decided to actually build her. Makes ordering parts a bitch if you don't know where they're going, after all. That's actually part of why the registry scheme exists.
Not necessarily. My experience is with aircraft production, but I can't imagine that it would be much different for ships (or fictional starships). When you get down to specific aircraft, there are
many different ways to refer to it.
For example, on the Super Hornet line, we referred to them as E1, E2, F1, etc. They also have a serial number that you can see near the tail. Out in the fleet, they also have a squadron number assigned (I'm not certain as to what the right term is). And I can assure you there were at least one or two other designators that I'm not remembering. And they were
all specific to
that aircraft.
Another example is the P-8A Poseidon. We engineers typically refer to the individual aircraft as T1, S1, etc., while their effectivity calls out YP001, YP005, etc., and they also have a line number (2589, 2608, etc.). And I'm sure the Navy will assign them their own number as well, while a commercial 737 (which the P-8 is based on) will have a registry assigned (N665US, etc.).
Note also that for the commercial/private planes, I have seen cases where the registry was changed. Usually that's because it changes countries, but there are also cases where it changes in-country.
My point is, the registry "NCC-1701-A" is most likely not the only designator that that specific hull is known by. It's just the only one really visible to the general public (and us viewers).
And that's exactly the point I was making as well.
There may be a "construction contract," AND a "hull number," AND a "navigational contact code," AND an "active service status code" and, during construction, a some form of logistical code that goes away once construction is completed.
Oh, and to further complicate matters... each SUBSECTION and each SUBSYSTEM would be tracked by such a code as well.
BJ and I, TGT, and several others on here have dealt with this... but many of you probably haven't.
Did you know that every single replaceable component in any military application today requires its own fully-traceable unique item designation? And by the way, I chose that description for a reason... because the official term for this is UID. (To make matters more confusing, it's a subelement of a larger system called IUID... thank your friendly neighborhood government for that!)
Here's a starting point in case anyone's interested in learning more:
http://en.wikipedia.org/wiki/IUID
This is every single component which may ever be removed and/or replaced anywhere other than in the original factory. Every item has a unique identifier, in the form of a 2D data matrix, which is then tied into a vast database (stored simultaneously in multiple locations, in case one system crashes or is destroyed). You can trace every single part ever made, from the time it leaves the original factory, through every removal, every maintenance operation, every refurbishing, every location where it may have been stored... EVERYTHING.
Oh, and this is applied to people too... which, frankly, sort of creeps me out... but oh well.
The point is... an airframe is made up of MILLIONS of uniquely-identified components, and uniquely-identified subassemblies. All of which are traced at every single step by a complex logistical tracking system.
I can't see it getting any LESS complicated with the construction of a starship, can you?
Now, note that (as BJ mentioned), this has ABSOLUTELY NOTHING to do with the final aircraft ID number, nor the "tail number" assigned to the aircraft, NOR THE TRANSPONDER ID CODE.
But it has absolutely EVERYTHING to do with what Vance mentions, regarding assembly/construction traceability.
The two are simply totally different, and totally unrelated, issues.
