They make a good contrast to the British E class, which had a pair of 6" more (but only one gun broadside more) and a knot or two of speed faster. To attain that superiority the British ship was over 2,000 tons heavier and almost a 100 foot longer.
ARA Rosario (CL-1925)
The two Rosario class cruisers were the first modern ships to be built in the
upgraded and reworked Bahia Blanca shipyards. They were more a statement on how
far the Argentine designers and builders had to go than any excellence. The
Argentine designers followed a lot of the features of the Germanic States ships
that they had in service. The one modern feature they added to the design was
the twin turret forward replacing the twinned singles on the bow of the later
German ships. The AA weapons at completion were the two 88mm Flak18 guns.

The various refits added new 37mm AA guns, a new gunnery director for the 5.9" weapons, and a set of six 20mm AA guns around the fore and after bridge superstructures.
