So, let me get this straight.
Someone's miffed because, canonically in TOS: The Tholian Web,
the dedication plaque on the Defiant
bridge said "USS Enterprise", but that was retconned for ENT: In a Mirror, Darkly
From what I can tell of my DVD copy of "The Tholian Web" and the TrekCore HD archives, the Defiant plaque is in darkness and too far away even on HD to where you can read it.
The USS Defiant in ENT can be a "Constitution-class" as there is no evidence that it cannot be.
Alright, excellent. My point was that if you could somehow make out or otherwise glean what the Defiant
plaque says in TTW,
it's going to have "USS Enterprise" staring you in the face, anyway.
And, thanks, GSchnitzer
, for the history lesson. I was aware of everything, except
the contents of the Space Seed
