This design comes from a discussion with myself and Brockpaine some time ago. He pointed out that an 8x12'' ship is has enough Quality for it to be effective at Quantity.

This ship is a war build construct utilizing older 12'' guns and having more speed that older Battleships.

Build for WWI it will become mainstay BB for WWII.

apologies for the type'O I'm drunk again

...it is distinctly odd to see my name as a class of ship...

Even worse, the designer is drunk!

coast defense, as part of an integrated system with mines, subs, aviation and coast artillery

or a heavy escort for a convoy. She'll threaten a mission-killing level of damage to even a full-up battlecruiser.

You pointed out my mistake. An 8x12'' ship will simply not cut it by 1914.


A little story behind it.

Brockpaine (formerly Springfield) class was ordered with the start of hostilities. As a war emergency design.
The alternative was a 12x14'' 30000t ship.
However manufacturer of the 14'' rifle was unable to supply the new weapons in time so the design went back to the tested 12'' gun.
48 units were ordered with entered service 1916-1922.
Those ships formed the battle line of Third District fleet.
