While these ships were designated as Light Cruisers they undertook the role of flotilla cruiser as leaders to the 30 M class destroyers that Brazil had obtained from the Royal Navy. The ships were the old Scout cruisers of the Adventure type and were in need of a complete overhaul and modernisation before they were acceptable for their new roles. While it would have been nice to achieve the same 34 knot speed as the M class destroyers this would have been impossible with the technology and ship shape that was to hand. The Royal Navy had cancelled various cruisers at wars end and the propulsion equipment ordered for those ships was fitted as a new set of engines and boilers into these ships. The 40,000 shp that these engines produced gave the ships a more than adequate 32 knots.

The ships armament was completely stripped out and replaced originally with 5 x 5.5" and 4 x 3"AA. Two of the 3" were replaced with 2 x twin 20mm while single 20mm were fitted where possible. Two twin 18" sets of torpedo tubes rounded out the armament.
