Ship project history: First Brazilian-built destroyers, known as Greenhalgh or M class. Drawings were developed by means of American experts (on the basis of American destroyer Mahan), considerable part of equipment therefrom was delivered: General Electric turbines, Babcock and Wilcox boilers, Bethlehem guns; fire control system and sonar. Despite it, building went slowly, and ships were commissioned only 6 years after laying. Original project provided 5 single 127mm/38 Mk12 guns, 4 single Oerlikons and 3 quadruple 533mm TTs, but during completion one 127mm gun and two TT mounts have refused in favour of strengthening of antiaircraft and anti-submarine armaments. One main gun placed in completely covered turret mount, remaining guns stood openly.

Modernizations: 1966, Mariz e Barros: - 2 x 1 - 127/38, 4 x 1 - 20/70; + 1 x 4 Sea Cat GWS20 SAM launcher, 2 x 24 - 178 Hedgehog ASWRL

Naval service: No significant events.
