Italy 6 ships (1930-32)
Alberto di Giussano, Alberico da Barbiano, Bartolomeo Colleoni, Giovanni delle Bande Nere, Luigi Cadorna, Armando Diaz.
The first six ships of the “Condotierri” large group were also the first postwar Italian cruisers to see service. Both classes were quite different but are seen there as sharing many similarities, like a 5000+ tons displacement, whereas the following D’Aosta group would almost double that, looking for the best compromise between speed and protection.
Surely, these classes were called “tin-clad cruisers”, and despite having a full 6in broadside, were only designed to take care of French large destroyers.
Note: This post is a placeholder. There will be a complete overview of the class in the next future, officially released on Facebook and other social networks

Design of the Giussano class
The four cruisers of the Giussano class were the first in the Condottieri serie. These were Albercio da Barbiano, Amberto di Giussano, Bartolomeo Colleoni and Giovanni delle Bande Nere. They were originally designed to respond effectively to heavy French destroyers of the Aigle, Jaguar and Lion classes. In order to catch them, they sacrificed everything to the speed. Indeed with 38 to 39 knots on trials, even 42 for the Barbiano, they earned the title of fastest cruisers in the world. However, their protection was almost non-existent, and their stability was poor, which made them bad shooting platforms. The range of their main artillery had to ensure protection from a distance, at the rate of 5 salvoes per minute.
Bande Nere prewar
These compromised reappeared quickly. Tolerated in peactime, their defects became more apparent in operations: They were uncomfortable, with poorly designed internal arrangements and had a severely limited autonomy. None survived the war. The Bande Nere was sunk by the submarine HMS Urge near Stromboli, the Colleoni in July 1940 by the cruiser Sydney, the Barbiano and Giussano by destroyers HMS Legion, Maori, Sikh and the Dutch destroyer Isaac Swers during the battle of the cape Bon in December 13, 1941.

Design of the Cadorna
The second group Condottieri counted two ships very close to the previous Giussano. They corrected one of the essential defects, stability, on the one hand by the adoption of lateral “bulges”, but also by lowering superstructures and a with better-distributed armament. These efforts were accompanied by a slight weight increase, their dimensions remaining unchanged. They also had roomier turrets. Equipped to lay mines, they could carry 138 of the smallest model. The Cadorna managed to reach 39.7 knots on trials. She was rearmed in 1944, receiving four 20 mm AA double mounts and losing both her catapult and torpedo tubes. She survived the war and remained in service until 1951. Her twin Armando Diaz received torpedoes from the submarine HMS Upright and sank during the escort of a convoy bound to Tripoli in February 1941.
