Egg shell with hammer!

Egg shell only because the decapping plate is the only belt armor specified "officially" with the remainder being stated as "clasified".

Its almost as if you are trying to make the ugliest ships possible.

I'd be worried about lack of secondary fire available on forward arcs.

why does she need so much range?

I emagine the extra range is needed in SS to be able to shoe horn adequate armor into the design and keep her weight down.

Personally I'd go with a crossdeck cat to improve her looks somewhat.

Aside from blowing up Turkish and Italian cruisers, what else will this ship be called on to do? I assume the reason for two after turrets is because she'll be running away a lot from larger Turk and Italian warships.

She's not going to win any beauty pagents, but then, my own current project is rather odd looking as well.

I'm not certain about the crane locations forward - it seems they would be bumping up against the conning tower a bit.

I'll echo Gavin's thoughts on the secondary battery's location. I'm not even sure I see the value of a single twin turret forward - low rate of fire at fast cruiser/destroyer targets won't likely yield many hits (subtantial ones when they occur, I'll concede).

I'm almost tempted to suggest you go even further and just concentrate the entire main battery aft in two triples - use the weight savings to add some secondaries forward beside and ahead of the catapult.

Rocky,

A backwards Dunquerque? Concentrate the main armament aft to free up the bow for secondaries and avaition?

I still like the 8-gun version from round 1. If the armament were to be concentrated, I'd say concetrate it forward, so she can smash screening vessels while determining enemy numbers and types. Like the French ships, that would only be a disadvantage to a narrow cone aft. Of course, neither this design or the previous 12" has that problem...
