Four more of the first batch ("Ascari", "Camicia Nera", "Geniere" and "Lanciere") were modified in 1941–42 by replacing the starshell gun with a full power 120 mm gun. The anti-aircraft machine guns were gradually replaced by 20 mm cannon, with up to 10–12 being fitted by 1943. Five ships ("Carabiniere", "Granatiere", "Fuciliere", "Legionario" and "Velite") had the aft set of torpedo tubes replaced by two 54 cal. guns , while "Fuciliere" and "Velite" also had their starshell guns replaced by a further pair of 37 mm cannon. "Fuciliere" and "Velite" were fitted with Italian radar, while "Legionario" was fitted with a German radar.
