Everything else we think we know of large starship designations comes purely from backstage sources of dubious "reality", or is left hanging, like the mention of Destroyers in DS9.
That's not entirely true. Tasha Yar described the parallel
Enterprise-D as a "Galaxy-class battleship" in
Yesterday's Enterprise, and the "dreadnought
Entente" was mentioned in communications chatter in TMP.
Also, the
Wambundu and
Hokule'a classes are not identified on screen; they originate in the
Encyclopedia.
On screen, we've seen or heard ship classes described as follows (parentheses are used for ships whose class has not been identified):
Battleship/Dreadnought:
(
Entente)
Galaxy (parallel universe)
Heavy Cruiser:
Constitution
Ambassador
Cruiser:
(
Tripoli)
Light Cruiser:
(
Drake)
Destroyer:
Saladin
(
Centaur)
Frigate:
New Orleans(
Renegade)
Escort:
Defiant
For what it's worth, I prefer the new Enterprise's size. Having spent some time aboard the modern Enterprise, I think its rough volume very unlikely for a starship similar to the one shown in TOS.
Check the crew compliments for the modern carrier and the starship, then get back to me on that one. The starship Enterprise has about 1/8th the crew of the carrier, and a little bit
more internal volume.
The NuEnterprise is nothing more than a penis-joke at its official size, made by people who don't realize how big 1000' long really is and what all could fit in there and quite-literally by people who didn't know that 'feet' and 'meters' were two different lengths.
I'm aware of the difference in crew complements. The portion of the modern
Enterprise's volume that is used for crew living spaces is significantly less than the portion of the TOS
Enterprise's volume that is taken up by the ship's nacelles - never mind that the TOS
Enterprise does require room for roughly 450 crew persons.
The crew spaces that we see on the TOS
Enterprise are themselves noticeably large (Uhura's cabin is larger than anyone's but the captain's aboard the carrier; it was larger than my 18-person compartment), to say nothing of the ship's broad corridors (
this passageway would be unusually large aboard the real
Enterprise; passageways along
these lines are much more common). Even phaser control and the bridge are luxuriously large. The modern
Enterprise, vast as it is, is desperate for space.
