Giussano-class cruiser

Giussano-class cruiser. The *Giussano*-class was a group of four light cruisers built for the Regia Marina in the late 1920s. Designed under the constraints of the Washington Naval Treaty, they prioritized very high speed at the expense of armor protection and seaworthiness. These ships, intended as fleet scouts and to counter large French destroyers, saw extensive service in the Mediterranean Sea during World War II.

Design and Construction

The design, led by General Giuseppe Vian, was a direct response to the French large destroyers of the *Jaguar* class and *Chacal* class. To achieve the required 36–37 knot speed, the hulls were lightly built and powered by machinery generating 95,000 shaft horsepower. Armor protection was minimal, with a thin belt and deck, a compromise that later proved fatal. The main armament consisted of eight 152 mm guns in twin turrets, a powerful battery for their size. Construction began in 1928 at shipyards including the Regio Cantiere di Castellammare di Stabia and Cantiere navale di Ancona, with all four vessels commissioned by 1931.

Ships in Class

The class comprised four vessels, all named after condottieri from Italian history. The lead ship was *Alberico da Barbiano*, followed by *Alberto di Giussano*, *Bartolomeo Colleoni*, and *Giovanni delle Bande Nere*. *Alberico da Barbiano* and *Alberto di Giussano* were built at Castellammare di Stabia, while *Bartolomeo Colleoni* and *Giovanni delle Bande Nere* were constructed at Ancona.

Service History

Upon entering service, the ships were assigned to the 2nd Naval Division and conducted numerous training cruises and fleet exercises throughout the 1930s. At the outbreak of World War II, they operated from bases like La Spezia and Taranto, primarily on convoy escort duties and minelaying missions. Their service was almost entirely within the Mediterranean Sea, involving actions against British Malta convoys and Allied naval forces. All four cruisers were lost in combat between 1940 and 1942.

Technical Specifications

The ships displaced approximately 5,110 tons standard and 5,506 tons at full load. Their machinery plant included six Yarrow boilers supplying steam to two sets of Belluzzo geared turbines, driving two shafts. The designed speed of 37 knots was often exceeded on trials. Armament featured eight 152 mm /53 caliber guns in four twin turrets, six 100 mm /47 caliber dual-purpose guns, and an anti-aircraft suite of 37 mm and 13.2 mm weapons. They also carried four 533 mm torpedo tubes and a catapult for two IMAM Ro.43 reconnaissance seaplanes.

Operational History

The class suffered heavy losses early in the conflict. *Bartolomeo Colleoni* was disabled by the Australian light cruiser HMAS *Sydney* and sunk by destroyers during the Battle of Cape Spada in July 1940. *Alberico da Barbiano* and *Alberto di Giussano* were both sunk in December 1941 by a force of British destroyers, including HMS *Legion*, in the Battle of Cape Bon while attempting a high-speed transport mission to Tripoli. The last survivor, *Giovanni delle Bande Nere*, was torpedoed and sunk by the British submarine HMS *Urge* in April 1942 south of the Strait of Messina. Their poor armor made them extremely vulnerable to both gunfire and torpedoes.
