[P3D]

The ESC is consistent in increasing ship speed from class to class, making sure the last ones have several thousand tons of useless machinery in a battleline action, but still too slow to catch a 12-year old battlecruiser.

[Carthaginian]

Basically, the ESC is making a fleet of poorly protected white elephants, skimping on escorts, and preparing itself for a short but legendary fall from glory. The Richmond was meant to stop this kind of thing from happening... but if you wish to fiddle while Rome burns, the CSA will happily keep you in rosin.

[The Rock Doctor]

As I understand things, ESC is the primary reason that Richmond is struggling. 

I don't care for the second class' bulged hull form or its very deep draught. 

[maddox]

I keep it with the 25000 tons Bretagnes and derivates for the "bulk fibre BB's" , the 35 Kton Britanies to flesh the oatmeal out.

And the 40 Kton Montmedies. Those have their own use.

[Borys]

Ahoj!
I'd be worried about the IMO poor stability. A little damage, taking in some water and the ship is unstable.
Ooooooooo - fourteen sixteen inchers!
I can't counter that, I'll only have twelve ... whimper ...

The Ocean II looked like a pretty good ship.

If you intend to Build the Ocean III in say Hamburg 88 Km up the Elbe river you might have a bit of a problem getting her down river.  ;)
