As both BBs is due for selling or scrapping the question is?
Replace them with two Ocean type BBs or as their maintask is in the Baltic Sea and the Elbe/Weser estuary and the norwegian fiords may build 4 of a Coastal BB:

*Twaps CT with newspaper* Bad..bad..no super-dreadnoughts..bad!!
For Baltic or Norvegian coast work, the concept is correct.
IMO, work in the BBs Battleline (to add 24x355) is neccessary, so, increase the speed, & secondary armament.
Jef ;)
Jeff, you're getting into the realm of an enlarged Graf Spee. I doubt it will become useable under 20 Kton.
On the other hand, 3 of those 20 Kton "all purpose Battleships" are a better deal than 4 13Kton coastal defense ships.
Unless powerprojection is not on the mind of the naval planners.
This kind of BB, update to 14000-16000t for Baltic Confederation.

Wow,what a drawing ,I am impressed.
As for their roles:
To provide heavy gun-fire support to mine-ships and Tbs ,near the vast Esc coast-line,so they are not intended to be a part of the "battle line".
I'd vote for more cruisers. That's what's really needed in that navy...
