Because it is not been menotioned on screen that this in fact the prototype of the Nova class, I am removing the mention of that from the first paragraph. --User:Ensign q
And I am removing the following because I really really really really hate the forcing of the "registry logic" on everyone:
However, the registry number doesn't correspond to this theory, considering the USS Equinox, itself a Nova-class starship, had the lower registry number of NCC-72381, suggesting the Equinox came before the Nova. It could be suggested that the USS Nova referred to in Star Trek Nemesis was a replacement for the prototype ship of the Nova-class.
...that is, the belief that starship registries somehow follow a logical pattern. --Alan 02:43, 21 July 2007 (UTC)
There's a precedent: see USS Constellation. That ship is named as a Constellation-class starship because it existed at the same time the Constellation-class was introduced, even though its class was never seen or even implied on-screen. - Mitchz95 02:04, June 20, 2012 (UTC)
