Once Again Vance, we don't know that about registries its only conjecture and its the same with the Constellation all conjecture.
Actually, no, everything I cited for the
Constellation (the NCC-1974 one, thanks Tomalak, I KNEW that, I just failed typing!) comes from TNG materials.
As for how things were intended by the writers, behind-the-scenes, etc.. keep in mind that a lot of us into this material have the 'people in charge' (when possible) on our friends list, our IM lists, see them post here, etc. It's really easy for me to figure out a writer's intent on this material
when I can just ask them.
Sadly I cannot, of course, do this for most of the people behind the scenes for the original series, obviously. We do, however, have a string of books published by them which gives exactly this information. Many of us attended conventions which had them give lectures and interviews. Some of us even have their own emails and posts on the old usenet days before the internet was coined.
In all honesty, I'm probably one of the handful of people who can give you the most
definitive answer on ship tech questions. The reason I can do this has nothing to do with my awesome greatness, and everything to do with having an insane contact list and lots of resources at my fingertips.
But in truth,
everything that we all do here is interpretation, even the official 'canon'. Mike and Andrew and Rick and Walter and Franz and Dana and Eric and Wang and many others whom I could name weren't making real ships, they were making a vision for television and games and movies and comics and toys and models. Each vision was tempered by the realities of marketing and budget. Sometimes, when we were really lucky, someone in that list would do something a bit more and flesh out this wonderful fictional universe just a bit more. Often it wasn't consistent, of course, and often things just got wonky. But it's largely okay, it's
Star Trek. We're meant to enjoy the ride.
So don't lecture me about the ships, the tech, the registries, or the 'real' meaning of it all. I will give you the real answer, and it's not one that comes from the 'in universe canon', but from our real-world experiences and the realities that went to making
Star Trek possible. It'll come across like I'm taking the piss out of you - largely because I am.
You see, we all have fun playing within our own visions and sharing them with others, but none of us - not even Gene Roddenberry - are truly
right. At best we can hope to get a tiny margin of error for the parts of Trek that we like.
