To big IMO. Build more REs instead as they are good enough against all current ACs and you have friends building "proper" ones.

[Tanthalas]

Agree that the 25 knot ships are to big, it was just a what would it take to comparison.  I am planing to jump to AQY but that will be esentialy the only change in the REs from the prestartup ones.

This has me a bit confused...

RMS Italia, Italia Battleship laid down 1900

Armament:
      6 - 11.00" / 279 mm 45.0 cal guns - 665.99lbs / 302.09kg shells, 120 per gun
     Breech loading guns in turret on barbette mounts, 1900 Model
     2 x Twin mounts on centreline, evenly spread

Is it 2 twins, 2 triples or 3 twins? I'm thinking triples aren't allowed yet so 2 or 3 twins.

Given previous statements that Italy will be going to AQY layouts, I'd expect 3 twins, yes.

[Tanthalas]

Oh I would absolutly love to use tripples, but nice catch its suposed to be 3 twins.  Honestly I wish we could use tripples right out the gate for dreadnaught style ships, then I would go AQY with tripples, as a simple evolution of my previous AQY ships with twins (make dreadnaughts a whole evolutionary thing instead of revolutionary per OTL)
