QuoteCBB is too expensive.

Well, it depends. If it is a purpose-built CBB then yes it probably is. If it is an old obsolete battleship redesignated as CBB then it is extending its life rather than scrapping her. It really depends on your approach. That was one thing I was thinking about with the old Norse BBs. They are obsolete for the 'modern' battle line, but can still be a pain to smaller enemy ships when hiding in Fjords or among many islands.

QuoteI prefer a kind of armored aviso with citadel configuration, more funny.

If you want to make it even more funny, then you need to add some miscellaneous weights for oars and rowers in case she runs out of fuel. ;D

Back aboard after nice holydays 8)

So, I have make some new SS & rework the 1890-1909 Building Plan.
Because the Building Plan must be in correlation with the Shipyards capacities... (there are some problems to resolve)

Well, here is 16000t AC4, (noted that Norse build 26115t Wicklow class similar to British BC Lion)
I do not choose this option & prefer to build a light Derfflinger, evolution of AC3 class

QuoteThis one is better with hoist for the 6'' guns

I think that the 1900 cruiser architecture tech would apply to those hoists (so they can only be used on ships laid down in 1902 or later or added with a refurbishment on pre 1902 vessels).

I'm also going to add that the posted design does not qualify under the DD/TB Tech as it does not meet the minimum 50% displacement dedicated to engines rule.

It's interesting, your Armored cruisers have evolved to be very similar to the various versions of my Knight class I've considered, though slightly larger than the design I settled on, and I dropped the TDS from my final vessel. I'll add it back in on the next version.

One note- you are free to use 75mm armor if you wish, it will be proof against most QF weapons with HE shells. However, it will be vulnerable to Semi-Armor piercing round with an AP cap, as it will be either Harvey or homogenous. Krupp Cemented armor needs a certain thickness to work, and the thinnest I know of was the Germans at 88mm, while the Brits went with a minimum of 100mm.

These are not Armored Cruiser but Armored GunBoat (AGB).
Built originaly, in 1890 to work with the battleships near the battleline, so, similar speed - 18kts & range are required.
I rework them as Armored Gunboat / light Battleships.
