It's vague when they got up to registries in the 5xxxx range, but regardless, Oberths aren't combat vessels. They're science vessels and maybe some other light duties, like ferrying people between starbases (i.e. the Cochrane in "Emmisary"), or testing new technologies (the Pegasus) etc. There's no reason older ones couldn't have been upgraded with new computer systems and warp drive and there's no reason newer ones couldn't have been built with those upgrades. The Ford thing's a bit of an exaggeration, but some designs may simply work really well, even after several decades. Starfleet may simply stick with designs when it finds a good one, something that clearly applies to the Excelsior. (Clearly the Klingons have the same attitude, given the lifespan of the BoP and battle cruiser designs, and these are ships that probably see combat far more often than 24th Century Starfleet did pre-Dominion War) My mistake regarding the Connie, but I suspect they may not have wanted to use the "hero" design from the movies on TNG, just as we never saw a Sovereign on-screen fighting the Dominion. Pretty much all of the alien ships got reused. The Ferengi were supposed to be the main badguys originally, so giving them a distinctive ship would've been considered a good investment. The Romulans actually were the main badguys. They got a great deal of use out of that Warbird design. (Perhaps a bit too much, if you ask me). All the other ones got modified and recycled as other alien ships-of-the-week on TNG and early DS9 and Voyager eps. I agree about the "Conspiracy" graphics. These were made during a time when there were no HD screen caps and no one who's name wasn't Okuda was expected to see it. Besides having some ship names that are just plain silly (USS Heart of Gold? Really?), we had registries as low as NCC-42 and as high as NCC-85183, much higher than the not-yet-built Defiant or Voyager. They'll likely have a bit more time than they did when making episodes, but the question is if Paramount is willing to shell out the $ to update those battle sequences. Personally, I'd be less interested in introducing new designs than I would be in just making those battles BIGGER! More ships! More explosions! More death, destruction, and mayhem! (What a twisted little f__k I am! ) Those ones seen in "A Time to Stand" were nasty (except for the Centaur). I don't think about those. And Starfleet likely sent EVERY ship fit for combat to the front lines, given the scope of the Dominion threat. Indeed. A ship is a collection of those things. Which means you can probably replace most of the interior systems while still retaining the outer design.
