Battleships for Peru

[The Rock Doctor]

The 340mm design is a safer bet in some respects - the guns will exist, there'll be four turrets versus two.

For a ship that size, I'd want a heavier secondary battery.  Perhaps shave off 10mm of deck armor to double the secondary?

[The Rock Doctor]

That's a pretty tough customer. 

Will the main belt be long enough to actually cover the ship's vitals?

[Jefgte]

The belt is slightly over the normal lenght.

[Tanthalas]

When has that minor detail ever stopped the NeoSwiss?

Since I took over (and started building 1kton cans while scraping the old light hulls), but honestly noone needs to worry about going to war with me (I want to normalise all my relations)

[Desertfox]

Aeiiii!!! What sort of (non) madman have we put in charge of NS?  ;D
