I entertained the idea of an standard battle-line similar to that of the USN Standard-Type Battleships. This thread will be solely for such designs.Standard:
24 Kts Max
8000nm @ 12 kts
All-forward Armament
20 Degrees Sloped Main Belt
All-or-Nothing Scheme - Armored Box is ~65% of the PPL
Seakeeping a bit above 1.00
Stability at 1.09
2.5" TDS extending all of underwater length.
Heavy Turret Face and Barbette Armor

And the most probable
Standard after the Model 1922.
Further Standards are probably going to require a jump to Dock Size 3.

Nice high main belt
He has been going 20* inclined lately, so it's really only 16'(2 decks) high.
