The NAeL Humaita (S44) is Brazil's first nuclear submarine. During the 2030 RIMPAC, the Humaita, Brazil's first home-built nuclear sub, proved to be a good enough platform to track Russian cruise missile sub Irkutsk, much to the later consternation of the Russians and proud gloating by the Brazilians.
