Three ships in SS (though I can't say I will build any of these three) I suppose I'd build two of one or one of two classes, either to replace the pre-dreadnoughts, or the dreadnoughts.
I might modify the designs to reflect secondary and other small weapons changes Chile goes through in the next decade.
Oh and these obviously don't outclass the Brazilian ships, but they are either cheaper or have a larger main gun.
