Project history

These were essentially Impetuosos with the after twin 127mm/38 replaced by a Tartar missile launcher, in rough analogy with the way the US Charles F. Adams class was derived from the Forrest Sherman class. They also had the much longer-range sonar of the US ships (the Impetuosos had modernized WWII high-frequency sets), and they lack the ASW mortar of the earlier design. Single 76mm/62s (two on each side) with Italian directors replaced the 40mm guns of the earlier ships, the Italian Navy having decided in about 1958 that the 40mm could not deal adequately with modem aircraft. Consideration was given to installing 135mm guns (as on the modernized Giuseppe Garibaldi) instead of US-type 127mm/38s. These ships were ordered in, respectively, 1957 and 1959.
