I know that the sizes of the new Enterprise and the Vengeance have been debated to death, but I have been unable to fine any such in-depth discussion concerning the Kelvin. I'm just wondering if there is any "official" length for the Kelvin, and if so does it fit with the observable details of the ship as seen on screen? The closest thing to an official length I've been able to find so far is the 1500ft (457m) stated on the Blu-ray, which has been, in turn, quoted on Memory Beta and several other sites. This length, however, seems to be something of a butt-pull as it doesn't quite fit with the on-screen evidence. For one thing, the Kelvin has various design elements that are virtually identical to those of another ship we see in the film--the USS Newton. This is significant because we later see the Newton docked at Space Dock along with the Enterprise and several other ships; and from that shot we can get a pretty good idea of their relative sizes. What we can see there also corresponds nicely with the size comparison chart depicted in Star Trek: The Art of the Film. That chart doesn't include the Kelvin, and yet if we insert an image of the Kelvin into that picture its quite clear that it's saucer, nacelle and secondary hull are all near perfect matches with those of the Newton. Now I realize that there's nothing that sais these various components of both ships HAVE to be the same size; yet their nearly identical proportions makes it a fairly reasonable assumption. Assuming that both the Kelvin's relative size to the Newton and the Newton's relative size to the Enterprise are as accurate as they appear, and assuming a 725m length of the Enterprise, the Kelvin should have a length of approximately 625m. So do you all think that 457m or 625m is the more accurate length for the Kelvin, or is it something else entirely? And would the larger size further undermine the idea that the Kelvin is supposed to exist in the Prime Universe as well as the new timeline? Let the debate begin!
