The only the chilean Admiral Lattore was anywhere nere servicable. The brazilian one gets guardship and the argentine ones wouldnt be much better. The chilean ship was the last ordered and served with the RN during WW1. As a navy the chileans closely aligned with RN traditions and kept thier ships in very good order.
Iirc, before the falklands the Argentine junta was warned about the professionalism of the chilean navy by i think the us ambassador.
