Construction and career

The five destroyers carried out patrols to defend Portugal's neutrality during the Second World War. Their anti-aircraft armament was revised during 1942–1943, with the 40 mm guns and one of the banks of torpedo tubes replaced by six 20 mm cannon. The ships were refitted by Yarrow from 1946 to 1949, with the machinery refurbished, anti-aircraft armament again revised to three Bofors 40 mm gun in powered mounts and three 20 mm cannon. Sonar and British Type 285 and Type 291 radars were fitted.
