Start mid 1919, in Callao Shipyards 2 x 6" cruisers - Cuntisuyu & Collasuyu



Note that NUS Admiralty choose, with the armament disposition, the possibility to engage 3 DDs.
Fore & aft 6" turrets could engage 2 differents targets & the middle 120mm guns had the own directory fire control for a third target.
