"What (in your opinion) would be the appropriate lengths / displacements for a corvette, frigate, destroyer, cruiser, battleship etc.? "

As you already know there is no agreed scheme of nomenclature and some of it is role based, some of it tradition.

But in my little world:

Corvette - less than 150ft and 1000 tons.

Frigate 200-350FT and less than 4000 tons.

Destroyer - 300-400ft and less than 8000 tons.

Cruiser - 400-500ft and less than 15000 tons. (Obviously this characterizes all the new Aegis "Destroyers" in service today and they should rightly be called Cruisers at 10000 tons)

Boats - All submarines of any displacement and day craft/landing craft/river and littoral patrol. PLUS anything the Coast Guard sails:).

After 15000tons it's all role-based. Carrier or defunct Battleship.

But could you imagine a 45T, 700ft "Balttleship" with all that steel armor...AND 396 VLS tubes?

Thanks, that makes sense to me.
