The two Veinticinco de Mayo-class heavy cruisers served in the Argentine Navy through World War II. They were the only post-Washington Naval Treaty heavy cruisers built for a South American navy. Both ships of the class were built in Italy by the OTO company, and commissioned into the Argentine Navy in 1931.
