As the recently commsioned VdM is roughly the size of an OTL USN AC I have decided against laying down a sister ship. I have instead layed down a more ambitious design which had been considered but not followed up. This new BB, which should be in service in 2nd HY 1910, will be longer, stronger, and without further ado, I give you......

I admit she's a little slow, but speed is not my top priority with BBs, so I'm content with 19.56kts.
I was expecting something evil to go with that evil laughter. Where's the evil?
Just going with a Halloween theme. If you need evil look towards the Pacific...
Ahoj!
4 feet of the MG barbettes are not covered by upper belt. Apart from that it's OK.
Borys
Lowered freeboard slightly on the forcastle and increased barbette armor 2"

It is always an option to shop around for the better stuff.
Bigger Main Guns for example.
France sold, and still is offering the 340mm L40 guns to all who are interested. Even in twin turrets. A few 350mm versions are sold too.
On the other hand, France bought 30 1909 tech 12000 Hp turbines from the UNK,and is using these to build newer Battleships and armored cruisers.
(while it's coming a deep night at Russia) We can offer you 356/45 guns.... in triple turrets ts! ::)
I think I'd reduce the end and upper belt armor a bit, to expand the main belt and/or turret armor.
No torpedo bulkhead?
