Buenos Aires-class destroyer

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

Design
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 2 these ships were modified by installing two single hand-worked 40 mm Bofors guns between the funnels replacing the original 3-inch 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 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.
