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.
The Spica class were a class of torpedo boats of the Regia Marina during World War II. These ships were built as a result of a clause in the Washington Naval Treaty, which stated that ships with a tonnage of less than 600 could be built in unlimited numbers. Thirty-two ships were built between 1934 and 1937, thirty of which entered service with Italy and two of which were sold to the Swedish Navy in 1940. The two units in Swedish service were classified as destroyers until 1953, then re-classified as corvettes. Although commonly referred to as torpedo boats due to their smaller displacement, the Spica class armaments were similar in design to destroyers and were intended for anti-submarine duties, although they often had to fight aircraft and surface forces as well. Twenty-three vessels were lost during World War II.
The Soldati class were a group of destroyers built for the Regia Marina during World War II. The ships were named after military professions. There were two batches; twelve ships were built in 1938–1939, and a second batch of seven ships were ordered in 1940, although only five were completed.
Benedetto Brin was a Regina Margherita-class pre-dreadnought battleship built for the Italian Regia Marina between 1899 and 1905. The ship was armed with a main battery of four 12-inch (300 mm) guns and was capable of a top speed of 20 knots. Benedetto Brin saw combat in the Italo-Turkish War of 1911–1912, including the bombardment of Tripoli in October 1911. She was destroyed by an internal explosion during World War I in September 1915, which killed over 450 of the ship's crew.
The Alpino class were a group of two frigates built for the Italian Navy during the Cold War.
Vittorio Emanuele was an Italian pre-dreadnought battleship, laid down in 1901, launched in 1904 and completed in 1908. She was the second member of the Regina Elena class, which included three other vessels: Regina Elena, Napoli, and Roma. Vittorio Emmanuele 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.
The Italian cruiser San Giorgio was the name ship of her class of two armored cruisers built for the Royal Italian Navy in the first decade of the 20th century. Commissioned in 1910, the ship was badly damaged when she ran aground before the start of the Italo-Turkish War in 1911, although she was repaired before its end. During World War I, San Giorgio's activities were limited by the threat of Austro-Hungarian submarines, although the ship did participate in the bombardment of Durazzo, Albania, in late 1918.
The Battle of Kunfuda Bay was a naval battle of the Italo-Turkish War between small squadrons of the Italian and Ottoman navies. On 7 January 1912, the Italian protected cruiser Piemonte and the Soldato-class destroyers Artigliere and Garibaldino, cruising the Red Sea, discovered six Ottoman gunboats, a tugboat, and a yacht in the harbor at Kunfuda. The vessels engaged for over three hours and five Ottoman vessels were sunk and four dhows were captured. Three of the gunboats were damaged during the battle and grounded on the beach to prevent them from sinking. The following morning, the Italian vessels returned to destroy the remaining three vessels; the yacht, which had been sunk, was later salvaged and seized by Italy. After the battle, the Italian squadron in the Red Sea was able to proclaim a blockade of Ottoman ports in the Red Sea and frequently bombarded Ottoman positions for the rest of the war.
The San Giorgio class consisted of two armored cruisers built for the Royal Italian Navy in the first decade of the 20th century. The second ship, San Marco, was used to evaluate recently invented steam turbines in a large ship and incorporated a number of other technological advances. The ships participated in the Italo-Turkish War of 1911–1912, although San Giorgio was under repair for most of the war. San Marco supported ground forces in Libya with naval gunfire and helped them to occupy towns in Libya and islands in the Dodecanese. During World War I, the ships' activities were limited by the threat of Austro-Hungarian submarines, although they did bombard Durazzo, Albania in 1918.
The Pegaso class was a class of 18 Italian sea-going steam-powered torpedo boats built between 1904 and 1909. They served in the Italo-Turkish War and the First World War, when one was sunk, and continued in use until the 1920s.
Calabria was a small protected cruiser built for the Italian Regia Marina in the 1890s, intended for service in Italy's overseas empire. She was laid down in 1892, launched in 1894, and completed in 1897, and was armed with a main battery of four 15-centimeter (5.9 in) and four 12 cm (4.7 in) guns. Calabria spent significant periods abroad, ranging from deployments to Chinese, North American, and Australian waters, in addition to periods in Italy's East African empire. She saw action during the Italo-Turkish War in 1912 in the Red Sea, primarily bombarding Turkish ports in the area. Calabria was reclassified as a gunboat in 1921, reduced to a training ship in 1924, and sold for scrap at the end of the year.
Puglia was a protected cruiser of the Italian Regia Marina. She was the last of six Regioni-class ships, all of which were named for regions of Italy. She was built in Taranto between October 1893 and May 1901, when she was commissioned into the fleet. The ship was equipped with a main armament of four 15 cm (5.9 in) and six 12 cm (4.7 in) guns, and she could steam at a speed of 20 knots.
The Lampo class was a class of six destroyers of the Italian Regia Marina built by the German Schichau shipyard from 1899–1901. They served in the Italo-Turkish War and the surviving ships in the First World War, before being disposed of between 1920 and 1924.
The Nembo class was a class of destroyer of the Italian Regia Marina. Six destroyers were built by the Pattison shipyard of Naples between 1899 and 1905, to a design based on the contemporary destroyers of the British shipyard Thornycroft. They were active in the Italo-Turkish War and in the First World War, where three were lost.
The Sirio class was a class of six sea-going steam-powered torpedo boats of the Italian Regia Marina built by the German shipyard Schichau-Werke from 1904–1906. They served in the Italo-Turkish War and the First World War.
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.
The Italian cruiser Pisa was the name ship of her class of two armored cruisers built for the Royal Italian Navy in the first decade of the 20th century. The ship participated in the Italo-Turkish War of 1911–1912, during which she supported the occupations of Tobruk, Libya and several islands in the Dodecanese and bombarded the fortifications defending the entrance to the Dardanelles. During World War I, Pisa's activities were limited by the threat of Austro-Hungarian submarines, although the ship did participate in the bombardment of Durazzo, Albania in late 1918. After the war she became a training ship and was stricken from the Navy List in 1937 before being scrapped.
Aretusa was a torpedo cruiser of the Partenope class built for the Italian Regia Marina in the 1880s. Laid down in June 1889 at the Cantiere navale fratelli Orlando shipyard, she was launched in March 1891 and was commissioned in September 1892. Her main armament were her six torpedo tubes, which were supported by a battery of ten small-caliber guns. Aretusa spent most of her career in the main Italian fleet, where she was primarily occupied with training exercises. At the start of the Italo-Turkish War in September 1911, she was assigned to the Red Sea Squadron in Italian Eritrea. She bombarded Ottoman positions in the Arabian Peninsula and took part in a blockade of the coast. Worn out by the end of the war in October 1912, Aretusa was sold for scrap that December and broken up.
Fulmine ("Lightning") was the Kingdom of Italy′s first destroyer. Commissioned into service in the Italian Regia Marina in 1900, she served in the Italo-Turkish War and World War I. She was stricken in 1921 and scrapped.
