Most Brooklyn-class cruisers were transferred to South American countries in the early 1950's. In game, we have ex-USS Boise as ARA Nueve de Julio. Former USS Brooklyn was transferred to Chile, along with USS Nashville and USS Philadelphia, together with USS St. Louis, to Brazil.
It's unlikely that WG will ever add just another Brooklyn class cruiser to give each nation one each. ...here is where this mod starts: I have converted the model of Nueve de Julio into NRB Barroso (C-11) by removing the Argentine coat of arms on the stern of the ship. This mod arrives just in time for the celebrations of the 200 years of the Brazilian Independence. Additionally, I have also modded the skin of the ASW bomber into "Arará", Catalina PBY-5, in service of the Brazilian Air Force. Named after one of the Brazilian merchant ships sunken by German submarines, the sinking of U-199 is credited to this Catalina.

HOW TO INSTALL THE MOD
Download the files with the mod from this link and unpack the bundle directly into your res_mods folder. The mod contains files that also change the Argentine flag and all in-game name of the ship to Barroso. For now, there's no camouflage in this bundle. In order to see the historical appearance of the Brazilian cruiser, you have to remove the camouflage or use the mod "Camouflage remover". The skin is, however, compatible with in-game camouflages.
If you would also like to have the name "Barroso" displayed, please refer to another thread where you can find the edited text file which changes the name "Nueve de Julio" to "Barroso" here.
Special thanks for AstreTunes for the mentoring and for answering a few questions I had along the way.
