Ships built by Venetian Arsenal

Quarto was a unique protected cruiser built by the Italian Regia Marina (Royal Navy) in the 1910s. Her keel was laid in November 1909, she was launched in August 1911, and was completed in March 1913. She was the first Italian cruiser to be equipped with steam turbines, which gave her a top speed of 28 knots (52 km/h; 32 mph). Her high speed was a requirement for the role in which she was designed to serve: a scout for the main Italian fleet.

Nereide was a Nautilus-class submarine in the Italian Royal Navy (Italian: Règia Marina) during World War I. She was built 1911–1913 at the navy yard at Venice and was sunk in 1915 by the Austro-Hungarian submarine U-5 under the command of Georg Ritter von Trapp. Nereide's captain, Carlo del Greco posthumously received the Medaglia d'Oro al Valore Militare for his actions when Nereide was sunk.

Otaria was one of five Glauco-class submarines built for the Regia Marina (Royal Italian Navy) during the early 1900s. The boat served in World War I and ceased service in 1918.

Glauco was one of five Glauco-class submarines built for the Regia Marina (Royal Italian Navy) during the early 1900s. The boat served in World War I and ceased service in 1916.

Pietro Micca was the first torpedo cruiser built by the Italian Regia Marina, and one of the first vessels of the type to be built by any navy. She was laid down in February 1875, launched in August 1876, and completed in July 1877. Details of her armament are contradictory, with various sources reporting a range of torpedo weapons, including a single 16-inch (406 mm) torpedo tube, a pair of tubes of undetermined diameter, and as many as six tubes. She proved to be unable to reach the projected speed of 17 knots (31 km/h; 20 mph), and so she did not see much active service. She remained in the Regia Marina's inventory until 1893, but spent most of her 16-year life in the reserve.

Stromboli was a protected cruiser of the Italian Regia Marina (Royal Navy) built in the 1880s. She was the second member of the Etna class, which included three sister ships. She was named for the volcanic island of Stromboli, and was armed with a main battery of two 254 mm (10 in) and a secondary battery of six 152 mm (6 in) guns, and could steam at a speed of around 17 knots (31 km/h; 20 mph). Her career was relatively uneventful; the only significant action in which she took part was the campaign against the Boxer Uprising in China in 1900. She returned to Italy in 1901 and spent the rest of her career in reserve or as an ammunition ship, apart from a brief stint in active service in 1904. Stromboli was stricken from the naval register in 1907 and sold for scrapping in 1911.

Francesco Morosini was an ironclad battleship built in the 1880s and 1890s for the Italian Regia Marina (Royal Navy). The ship, named for Francesco Morosini, the 17th-century Doge of Venice, was the second of three ships in the Ruggiero di Lauria class, along with Ruggiero di Lauria and Andrea Doria. She was armed with a main battery of four 356 mm (14 in) guns, was protected with 451 mm (17.75 in) thick belt armor, and was capable of a top speed of 17 knots (31 km/h; 20 mph).

Faà di Bruno was an Italian monitor built during World War I. Completed in 1917, the ship played a small role in the 11th Battle of the Isonzo later that year. She was decommissioned in 1924, but returned to service as the floating battery GM 194 at the beginning of World War II and was towed to Genoa and where she spent the rest of the war. The ship had her guns disabled when the Royal Navy bombarded Genoa in 1941. GM 194 was captured by the Germans after the Italian Armistice in 1943 and was turned over to the puppet Repubblica Sociale Italiana (Italian Social Republic) that they installed afterward. She was scuttled at the end of the war and subsequently scrapped.

Francesco Ferruccio was a Giuseppe Garibaldi-class armored cruiser built for the Royal Italian Navy (Regia Marina) in the first decade of the 20th century. The ship made several deployments to the Eastern Mediterranean and the Levant during her career. At the beginning of the Italo-Turkish War of 1911–12 she bombarded Tripoli and then Beirut in early 1912 before being transferred to Libya. During World War I, Francesco Ferruccio's activities were limited by the threat of Austro-Hungarian submarines and she became a training ship in 1919. The ship was struck from the naval register in 1930 and subsequently scrapped.

Narvalo was one of five Glauco-class submarines built for the Regia Marina (Royal Italian Navy) during the early 1900s. The boat served in World War I with defensive purposes and was demolished in 1918.
