For the new guys on board - N-verse France continues the design phylosphy which gifted the world with the following atrocities errr "striking looking" ships ...

Thanks Borys, I'd ALMOST forgotten Depuy De Lome..dammit...

Just wait till the French master the art of non-Euclidian geometry...

The Rock Doctor

I've viewed the pictures and retained my sanity, so I think you have not.

maddox

The plan is working.... ;)


But, is JR worth being build?

The Rock Doctor

As a raider/counter-raider, perhaps.

TexanCowboy

I would go 3x2 instead of 2x3... just so I don't feel obligated to make a song called "Sink the Ducable".
France has triple 10.83''?

maddox


TexanCowboy

And that would look more structured. May I suggest a ship with 6 10.83'' in twin turrets?

The Rock Doctor

If he did that, he'd just be building an Arquero...

TexanCowboy

Hides Transylvania redesign in corner... hey maddox, will you do it?

maddox

3 Twin turrets.

Me no like.

Try it with a long raised deck (60-70% mid break) and an AXY setup.. not so good for forward fire, better than AQY for all around fire, and better stability then ABY because the X turret isn't "raised" by SS thought process because of the extended deck. Think HMS Tiger w/ 3 turrets.
