I think those are stacked turrets, ala Kersarge. KWorld. if you want your shell weights to sick as whole pounds, for some reason you need to add a .00 onto the end of each one. Otherwise it adds that annoying .01, and yes it bugs me a bit when it does that to my designs.
You smug-faced crowds with kindling eye
Who cheer when solider lads march by
Sneak home and pray that you'll never know
The hell where youth and laughter go.

I think its too early for secondaries in twins. Except of course for something like a 10" intermediate battery.

These 6" twin secondaries are in stacked turrets, like on USS Kearsarge or USS Virginia.  They're not mounted separately, should have made that clear.

Here's a version of the same design without the stacked turrets.

   Ship tends to be wet forward

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 103.2 %
      - Above water (accommodation/working, high = better): 110.8 %
   Waterplane Area: 32,275 Square feet or 2,998 Square metres

      - Overall: 1.00
   Adequate machinery, storage, compartmentation space
   Adequate accommodation and workspace room
   Ship has slow, easy roll, a good, steady gun platform
   Good seaboat, rides out heavy weather easily

Below-decks miscellaneous weight accounts for 4 submerged broadside 18" 5m wet heater torpedo tubes and 8 reload torpedoes.

Above-decks miscellaneous weight allows for a long-range wireless installation.

QuoteA quick design sketch of a heavy armored cruiser/fast battleship to match the French armored cruisers with their 274mm guns.  The USN lacks any guns between the 10"/45 and the 12"/40, so this design carries the 12"/40.

Armament race is expensive with expansion engines ...

I could built a lighter version 8500-9000t with 2T2x274-21kts.
or re SS with 3T2x240mm guns from D'Entrecasteau AC

Italia is honestly Snickering at all of them... only a knot faster than my True BBs, not worth it IMHO (actualy if I slashed their armor to the level on these ships I could be a knot faster... yes I experimented with it...)

I'm not thrilled with this idea, at all, having planned on an 18-knot battle line being sufficient until new engine techs come along and become useful.  But that happy world may have been blown up with the stroke of a pen.

Build big fast ships is not cool for medium & small countries.
They are out of the game before playing  :'(

Ok France didnt built cruisers with 3T2x274-12400t
I built a mixture of AC3 & AC4 - 12400t/8500t

10450t-2T2x274+164mm guns-21,..kts

You could be Russia, having to defend against two great powers on land and three on the sea, separated by thousands of miles. That's why my armored cruisers are basically fast light battleships. They might not be able to outrun other armored cruisers, but they can certainly put up quite the fight against most ships able to catch them, Italian battleships being about the only warships they are vulnerable to.
