Ahhh okay, I didn't know about the fan schematics version, I just remembered the version from the DC comics being all wierd and vague heheheh. That totally gave me an idea for another thread in the art forum though!
Interestingly though, I don't remember the Hornet resembling the Ambassador class at all... Where does that come from?
The Ambassador class is damn cool though.
I've never seen the U.S.S. Hornet
so I can't really comment on that.
But going by the fan schematics here:
The saucer and engineering hull are similar to the Ambassador-Class, though on a smaller scale. There is some familial resemblance between the two classes, not surprising given they were developed at the same time.
