The Freccia-class destroyer was a class of destroyers built for the Regia Marina in the 1930s. Four modified ships were built and delivered in 1933 for Greece.
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 which were sold to the Swedish Navy in 1940. The two units in Swedish service were classed 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.
Hydra was a Greek destroyer of the Kountouriotis class, which served with the Hellenic Navy during the early stages of the Second World War. It was named after the Saronic Gulf island of Hydra, which played an important role in the Greek War of Independence, and was the fourth ship to bear this name.
The Ariete-class torpedo boats were a group of destroyer escorts built for the Italian Navy during World War II. They were enlarged versions of the Spica-class torpedo boats and designed to escort convoys to North Africa. Of the 42 units planned, sixteen ships were eventually ordered but only one was completed by the time of the armistice, Ariete, built in the Sestri Ponente shipyards and commissioned on 5 August 1943. The namesake ship was also the only one to survive the war. After the war it was ceded to the Yugoslav Navy (1949), and renamed Durmitor.
The Indomito class was a class of destroyers of the Italian Royal Navy before and during World War I. Six were built at Naples by Societa Pattison between 1910 and 1913. They were the first large Italian destroyers and the first fitted with steam turbines. The class is sometimes also called the I class. Two of the class were sunk during World War I, but the four surviving ships remained in service until 1937–38. One of the class, Insidioso, was reinstated during World War II and served in the Règia Marina and the German Kriegsmarine before being sunk by U.S. aircraft in late 1944.
Strale was one of four Freccia-class destroyers built for the Regia Marina in the early 1930s. Completed in 1932, she played a minor role in the Spanish Civil War of 1936–1939 supporting the Spanish Nationalists and served in World War II.
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.
The Orione class was a class of four sea-going steam-powered torpedo boats of the Italian Regia Marina built by the Odero shipyard of Sestri Ponente from 1905 to 1907. They served in the Italo-Turkish War and the First World War.
Cantieri navali Odero is a defunct Italian shipyard. Founded in 1846 by the Westerman brothers in Genoa-Sestri Ponente, the company was taken over by Nicolò Odero in 1872. Together with the Ansaldo-San Giorgio shipyard at Muggiano and the armament works of Vickers-Terni, it was amalgamated into Odero-Terni by Attilio Odero, which, in turn, absorbed the Cantiere navale fratelli Orlando of Livorno two years later. The consolidated company became the Società per la Costruzione di Navi, Macchine ed Artiglierie Odero-Terni-Orlando (OTO). The shipyard was closed in 1949.
Urania was a torpedo cruiser of the Partenope class built for the Italian Regia Marina in the 1880s. She was built by the Cantieri navali Odero shipyard; her keel was laid in February 1889, she was launched in June 1891, and was commissioned in July 1893. Her main armament were her six torpedo tubes, which were supported by a battery of ten small-caliber guns. Urania spent most of her career in the main Italian fleet, where she was primarily occupied with training exercises. She was still in service at the outbreak of the Italo-Turkish War in September 1911, but she did not take part in any operations. Instead, she remained in Italian waters and was broken up for scrap in January 1912.
Dardo was one of four Freccia-class destroyers built for the Regia Marina in the early 1930s. Completed in 1932, she served in World War II. The ship was captured by the Germans after the Italian armistice in September 1943 and used by the Kriegsmarine under the name TA31 until she was sunk in April 1945.
Antoniotto Usodimare was one of a dozen Navigatori-class destroyers built for the Regia Marina in the late 1920s. Completed in 1929, she served in World War II.
Luca Tarigo was one of a dozen Navigatori-class destroyers built for the Regia Marina in the late 1920s. Completed in 1929, she served in World War II.
Emanuele Pessagno was one of a dozen Navigatori-class destroyers built for the Regia Marina in the late 1920s. Completed in 1930, she served in World War II.
Lanzerotto Malocello was one of a dozen Navigatori-class destroyers built for the Regia Marina in the late 1920s. Completed in 1930, she served in World War II.
The La Masa class was a class of eight destroyers of the Italian Regia Marina constructed during the First World War. Like other obsolete Italian destroyers, they were reclassified as torpedo boats in 1929, and seven ships served throughout the Second World War. Two ships were sunk in air attacks while in Italian service during the Second World War, one was sunk by a mine, two more were scuttled. The remaining two ships survived the war and continued to serve in the post-war Marina Militare, being decommissioned in 1957–1958.
Giuseppe Sirtori was the lead ship of the Giuseppe Sirtori class of destroyers built for the Italian Regia Marina during World War I.
Giovanni Acerbi was the second of four Giuseppe Sirtori-class destroyers built for the Italian Regia Marina during World War I.
Vincenzo Giordano Orsini was the third of four Giuseppe Sirtori-class destroyers built for the Italian Regia Marina during World War I.
Francesco Stocco was the third of four Giuseppe Sirtori-class destroyers built for the Italian Regia Marina in the 1910s.
