Just to throw some numbers out there for you.

Old  US WWII CAs (Cleveland) were in the range of 13,000 tons. The
CLAA's (Atlanta, Oakland, Juneau Classes)  were ~8,500 tons. The
Baltimores were 17,000 tons.

The Longbeach GGNs were 16,000 tons.
The Ticonderogas got smaller at 10,000 tons (smaller computers ya know
but carry a the same weapons compliment and are more capable and faster
firing).

Arligh Burkes and Sprucans are 9,000 tons
Oliver Hazard Perry Class FFGs are 4,000 tons. The LCS will be 3,000
tons.

Mine hunters and other auxiliaries have gotten bigger.

European DD's are in the 4,000 to 7,000 ton range (Type 42s and the new
type 45s as well as the French Suffrens and Forbins).

Bear in mind, that the WWI Dreadnaught era Battleship was ~16,000 tons
(South Carolinas) . The Maine, a pre-dreadnaught, was 6,000 tons, the
Connecticuts (best of the US made pre-dreadnaughts) were 16,000 tons.
The Montana's were to have a 70,783 ton full load. HMS Dreadnaught
herself was 18,000 tons. That's quite a growth of tonnage in less than
40 years wouldn't you say?

Carriers have done the same thing. The Lexington and Saratoga were
38,000 tons. The Yorktowns were 25,000 tons. The Essexes were 35,000
tons. The Nimitz class carriers gross out at 100,000 tons!

Battleships didn't stop being battleships, they just got larger.
Destroyers and Frigates (think DDE and sloop) didn't stop doing what
they do, they've just gotten bigger. And Bigger means more $$$$ to
build, even for the US.

In Ship design theory for wet navies, longer hulls mean more speed. This
isn't the case with space craft. Mass is mass. If it's not needed it's
burning reaction mass or just slowing you down. So uniform hulls for
different roles don't buy you savings there or should not on theory.
