Marius New BB of Italia Proposal

[Tanthalas]

ya I made the decision actualy with my first 9X14" ships to take this route, the 12" ships are basicly maxed. (im not even sure i can make 100% oil fire work on them)

[Eugenius]

Heh-heh...taking a page from Ukraine's two turrets aft, one turret forward battleships?  ;)

[Tanthalas]

I was actualy planing them b4 you posted tie request, its part of my evolution system ^.^  (if I actualy follow the whole thing ill end up with 12 gun 4 turret ships)
