Maybe you could mention it's secondary hull in a novel and clear the matter up !
I'd rather leave it ambiguous, up to the individual reader to decide.
Thank you for that. As much as I admire the refit design, I like that the NX-01 is more of a predecessor to the Akira class than the Constitution class.
I'm okay with the NX-refit being a "running change" to the way the NX ships were built after the NX-01 was retired, or even as a later class of starship. It's definitely the next developmental step for starships, but part of the NX-01's appeal imho is that her time was before that step was taken.
