@JSB, I assumed it like the 2nd point on your list, as the literal first Dreadnought (for my obscure nation
).
I'm updating my Fort-Albany class anyways, and working on another 1911 dreadnought concept, as well as the 1906 concept below, so when I get them done, I'll post all 3 at the same time.
I've worked up an SS report for a 1906 Dreadnought for Denton and I'm curious what ya'll think.
The configuration is like that of HMS Dreadnought, but without the X turret (only 4 turrets).

Overall survivability and seakeeping ability:
Survivability (Non-critical penetrating hits needed to sink ship):
13,405 lbs / 6,080 Kg = 15.5 x 12.0 " / 305 mm shells or 1.8 torpedoes
