The Veinticinco de Mayo design was derived from the Italian Trento class, visually identifiable by the closely paired main guns. Three twin turrets were mounted with an elevation of 45 degrees for firing. The design had been compacted from the original Italian product, and thus it carried significantly less armor. Regardless, the ship proved popular with the Argentine Navy.

[edit] Units

Both ships of the class were built in Italy by the OTO company , and commissioned into the Argentine Navy in 1931. Despite Argentina's declaration of war on 27 March 1945, neither vessel played a role in the conflict.
