Significant upgrades were made to the weapons systems of the two ships that survived Matapan, similar to those made to the "Maestrale"s. One torpedo tube mounting was replaced by two &lt;a href="Cannone-Mitragliera%20da%2037/54%20%28Breda%29"&gt;/54&lt;/a&gt; guns;  cannon, a 120 mm star-shell gun and depth charge throwers were also installed. Before the end of the war, one ship, "Oriani" had German Seetakt radar and an additional 20 mm cannon.
