I build a copy of the the 356mm/L50 that the British designed for the Russian its a nice 14" gun using the 1911 Gun Technology.  Its tought to keep ones ships and guns really really modern.

[Marek Gutkowski]

I'm not a fan of speed because one fast BB will have to sail alone or drag its feet with the rest of the fleet.
Or building a whole new battleline with will take something like 20 years.
Rebuilding existing ships is expensive and at the end of the day you still have a old ship.

[TexanCowboy]

You still have the oddball battlecruiser....Nelson style, 30 knots.

[The Rock Doctor]

I'd agree with Carth about generic battleships:  I always picture a QE class when I heard that kind of phrase.

The Russian class for sale does offer a reasonably useful package, and one could swap out the triple 12" for twin 14" or 15". 

For your purposes - I'd agree speed is not so important.  I'd probably emphasize protection in your case, as you'll probably be outnumbered and outgunned anyway.  Best to keep the ship functional and a threat.
