Each time I see the bridge dedication plaque of the USS Defiant in "In A Mirror Darkly" (ENT) I don't know whether I should laugh or cry. It says "Constitution Class" while the same spot on the Enterprise's bridge dedication plaque is crystal clear: "Starship Class".
What's the last known TOS episode which shows the dedication plaque as "Starship Class?" I really can't remember any episode where I could actually read the plaque.
Maybe the original Enterprise and some of the early sister ships were Starship Class and then at some point they were changed to something less generic. Assuming the Defiant was built later, the ship class could have changed to Constitution by then.
