There's a design out there, somewhere, for a historical never-built American BC class, usually dubbed "Chesapeake". It's got three triple 14", majority aft and non-superfiring.
I'm trying to find a pic but just get oodles of sail frigates and starships. Anybody have one?
Unfortunately, the Russian Khranitel class seems based on this principle, albeit with two turrets forward and one aft. Not entirely ideal, from my point of view, but what's built is built...
There's also a layout drawing in Friedman's "US Cruisers", but I don't have a scan of that.
Its basically a Northampton with 25 extra feet length wise and a single turret forward. Appearance wise it looks more like a Pensacola class with not much superstructure....if that's the one you are referring too. Otherwise I can't find a picture in Friedman's book.
