Not according to the techs Peru has.

Not according to the techs Peru has.

agreed which is why I didnt build somthing like this for myself, but since he was already useing the 1909 engine i figured he would have to import it anyway, so may as well import the turrets to, or have the whole ship built elsewhere in 1905.  I actualy playd around with having somthing like that.  decided it was to heavy, only to realise recently that i gyped myself almost 20K tons because i was counting standard instead of light.  so technicly i could have had 1 realy capable 1905 bb ><

[Ithekro]

What about adding more 4" guns so you can better counter lighter vessels your 8" guns won't be able to track so well.

Have we considered open deck mounts on top of the turrets?  I kow that was common in this era.

[Tanthalas]

I tryd to figure out how to do that lol, couldnt come up with a way i liked.

[Borys]

Ahoj!
I think that putting the 4 inchers o top of turrets is the only way to go.
I forgot to comment on this, but having both Primary and Secondary Main Calibre guns in turrets and shooting at deck level means that the weather deck is an unhealthy :) place during combat. Thus the 4 inchers either have to go into casemattes, or have to be "above freeboard".

I would suspect that by using the "centerline equal fore>=aft with raised mounts" you would get the 4" mounts on top of the MB turrets.... I think, therefore there is a resonable chance I'm wrong.
