The Buenos Aires-class destroyers were a group of destroyers built for the Argentine Navy in Britain in the 1930s.


The ships were based on the contemporary G-class destroyers building for the British Royal Navy, with some modifications to suit Argentinian requirements. After World War II these ships were modified by installing two single hand-worked 40 mm (1.6 in) Bofors guns between the funnels replacing the original 76 mm (3 in) anti-aircraft gun and two twin air-cooled Bofors unique to the Argentine and Swedish navies (instead of the more common water-cooled mounts) replacing the after bank of torpedo tubes. Radar and sonar was also fitted at this time and Santa Cruz landed "B" gun in favor of a pair of Hedgehog anti-submarine weapons.
