Giovanni delle Bande Nere was an Italian light cruiser of the Giussano class, which served in the Regia Marina during World War II. She was named after the eponymous 16th-century condottiero and member of the Medici family. Her keel was laid down in 1928 at Cantieri Navali di Castellammare di Stabia, Castellammare di Stabia; she was launched on 27 April 1930, and her construction was completed in 1931. Unlike her three sisters, the finish and workmanship on the vessel were not rated highly. She was sunk on 1 April 1942 by the British submarine HMS Urge.
The Condottieri class was a sequence of five light cruiser classes of the Regia Marina, although these classes show a clear line of evolution. They were built before World War II to gain predominance in the Mediterranean Sea. The ships were named after condottieri of Italian history.
Trieste was the second of two Trento-class heavy cruisers built for the Italian Regia Marina. The ship was laid down in June 1925, was launched in October 1926, and was commissioned in December 1928. Trieste was very lightly armored, with only a 70 mm (2.8 in) thick armored belt, though she possessed a high speed and heavy main battery of eight 203 mm (8 in) guns. Though nominally built under the restrictions of the Washington Naval Treaty, the two cruisers significantly exceeded the displacement limits imposed by the treaty. The ship spent the 1930s conducting training cruises in the Mediterranean Sea, participating in naval reviews held for foreign dignitaries, and serving as the flagship of the Cruiser Division. She also helped transport Italian volunteer troops that had been sent to Spain to fight in the Spanish Civil War return to Italy in 1938.
Trento was the first of two Trento-class cruisers; they were the first heavy cruisers built for the Italian Regia Marina. The ship was laid down in February 1925, launched in October 1927, and was commissioned in April 1929. Trento was very lightly armored, with only a 70 mm (2.8 in) thick armored belt, though she possessed a high speed and heavy main battery of eight 203 mm (8 in) guns. Though nominally built under the restrictions of the Washington Naval Treaty, the two cruisers significantly exceeded the displacement limits imposed by the treaty.
The Capitani Romani class was a class of light cruisers acting as flotilla leaders for the Regia Marina. They were built to outrun and outgun the large new French destroyers of the Le Fantasque and Mogador classes. Twelve hulls were ordered in late 1939, but only four were completed, just three of these before the Italian armistice in 1943. The ships were named after prominent ancient Romans.

Emanuele Filiberto Duca d'Aosta was an Italian light cruiser of the fourth group of the Condottieri-class, that served in the Regia Marina during World War II.

Giuseppe Garibaldi was an Italian Duca degli Abruzzi-class light cruiser, that served in the Regia Marina during World War II. After the war she was retained by the Marina Militare and upgraded. She was built by CRDA, in Stabilimento Tecnico Triestino shipyard Trieste and named after the Italian general Giuseppe Garibaldi.
The Etna class were two cruisers originally ordered in Italy for the Thai Navy in 1938 and subsequently requisitioned for service by the Italian Navy on the outbreak of World War II, neither ship was completed and the damaged hulls were scrapped after the war.
Varese was a Giuseppe Garibaldi-class armored cruiser built for the Royal Italian Navy in the 1890s. The ship made several deployments to the Eastern Mediterranean and the Levant before the start of the Italo-Turkish War of 1911–12. She supported ground forces in the occupations of Tripoli and Homs in Libya. Varese may have bombarded Beirut and did bombard the defenses of the Dardanelles during the war. She also provided naval gunfire support for the Italian Army in Libya. During World War I, the ship's activities were limited by the threat of Austro-Hungarian submarines and Varese became a training ship in 1920. She was struck from the naval register in 1923 and subsequently scrapped.
Regina Elena was the lead ship of her class of pre-dreadnought battleships built for the Italian Regia Marina. The ship was built by the La Spezia shipyard between 1901 and 1907, and was armed with a main battery of two 305 mm (12 in) guns and twelve 203 mm (8 in) guns. She was quite fast for the period, with a top speed of nearly 21 knots. Regina Elena was active in both the Italo-Turkish War with the Ottoman Empire in 1911–1912, where she participated in the Italian conquest of Cyrenaica, and World War I in 1915–1918, where she saw no action due to the threat of submarines in the narrow confines of the Adriatic Sea. She was retained for a few years after the war, but was ultimately stricken in February 1923 and broken up for scrap.
The Italian cruiser Vettor Pisani was the name ship of her class of two armored cruisers built for the Royal Italian Navy in the 1890s. She often served as a flagship during her career and frequently served overseas. On one of these deployments, the ship received a radio message from Peking, one of the first long-range radio transmissions to a ship. Vettor Pisani participated in the Boxer Rebellion of 1900 and the Italo-Turkish War of 1911–12, during which her admiral nearly caused a diplomatic incident with the Austro-Hungarian Empire. During World War I, her activities were limited by the threat of Austro-Hungarian submarines and she was converted into a repair ship in 1916. Vettor Pisani was stricken from the Navy List in 1920 and scrapped later that year.

Agostino Bertani was an Italian La Masa-class destroyer. She was commissioned into service in the Italian Regia Marina in 1919.

Reclassified as a torpedo boat in 1929, she took part in the Mediterranean campaign and the Adriatic campaign of World War II until the Italian armistice with the Allies in 1943, shortly after which her crew scuttled her to prevent her capture by German forces. She was involved in four collisions during her operational career.
Salvatore Toscano was an Italian naval officer during World War II.
