Ahoj!
http://www.ww2aircraft.net/forum/ww2-general/good-old-ships-argentine-armada-1723.html

Strangely for a forum of such a name, it is about Argentinian warships :)

About the design.
Nice range.
Totally overgunned - 6x6" is enough. Or 2x6"+8x4".
Casemattes on such a small vessel are useless. 
Simply make her smaller. Or maybe cut deck to 1 inch, and try a belt?

She needs more speed, get 1909 Turbines. You will need them. Other than that she looks good if a bit overgunned.

[Sachmle]

Best speed with 1905 turbines w/o making her an too light. Already lighter than San Luis she's replacing
