No, that's not what I said. I said that in the case of the Enterprise-B, the intent, with the TNG Enterprise history wall showing the Excelsior class profile, the use of the Excelsior studio model in GEN, and the dedication plaque stating that the ship is Excelsior class, that there's no argument that the Ent-B is an Excelsior. You are welcome to debate that all you want, but it's not going to change those facts, or my mind. The only reason why the add-on parts were attached to the model was so that those parts could be damaged without damaging the main model. They weren't added on because someone decided the ship was meant to be a different class, which was the opposite case with the Bozeman. Now, that's all I have to say about the Enterprise-B. Again, the question remains as to how Starfleet arbitrarily designates a particular ship as a variant of one class, or a different class altogether, based on subtle or not-so-subtle differences between individual ships. I doubt there will ever be an answer to that question.
