The Regia Marina (RM) or Royal Italian Navy was the navy of the Kingdom of Italy from 1861 to 1946. In 1946, with the birth of the Italian Republic, the Regia Marina changed its name to Marina Militare.
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 Turbine-class destroyer was a group of eight destroyers built for the Regia Marina in the 1920s. The ships played a minor role in the Spanish Civil War of 1936–1937, supporting the Nationalists. All the ships of the class were lost during World War II.
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.
Motoscafo armato silurante, alternatively Motoscafo antisommergibili and commonly abbreviated as MAS, was a class of fast torpedo-armed vessels used by the Regia Marina during World War I and World War II. Originally, "MAS" referred to motobarca armata SVAN, Società Veneziana Automobili Navali.
Carlo Fecia di Cossato was an officer in the Regia Marina, in command of submarines and torpedo boats during World War II. He was credited with the confirmed sinking of 23 enemy ships. He was also a recipient of the Knight's Cross of the Iron Cross and of the Gold Medal of Military Valor, the highest decoration of the Italian Armed Forces.
The Battle of the Espero Convoy on 28 June 1940, was the first surface engagement between Italian and Allied warships of the Second World War. Three 36 kn Italian destroyers made a run from Taranto for Tobruk in Libya to transport Blackshirt anti-tank units, in case of an armoured attack from Egypt by the British.
The Italian destroyers of World War II comprised a mix of old warship designs dating from World War I and some of the most modern of their type in the world. These destroyers also varied in size from enlarged torpedo-boats to esploratori.
The Cagni or Ammiraglio Cagni class was a class of submarines built for Italy's Regia Marina during World War II.
The Comandanti Medaglie d'Oro class were a group of 20 destroyers ordered for the Regia Marina during World War II. Nine had been laid down by the time of the Italian armistice in September 1943 and all but one of those ships which had not yet been laid down were cancelled. Of those that had been laid down, none had been launched by that time and all were subsequently scrapped.
Beograd was the lead ship of her class of destroyers, built for the Royal Yugoslav Navy in France during the late 1930s, and designed to be deployed as part of a division led by the flotilla leader Dubrovnik. She entered service in April 1939, was armed with a main battery of four 120 mm (4.7 in) guns in single mounts, and had a top speed of 35 knots.
The Rosolino Pilo class was a class of eight destroyers of the Italian Regia Marina constructed before and 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 by mines while under Italian service during the Second World War, with two more being seized by Nazi Germany following the Italian Armistice in 1943. The remaining three ships survived the war and continued in use with the post-war Italian Navy, with the last two of the class being decommissioned in 1958.
Leone Pancaldo was one of twelve Navigatori-class destroyers built for the Regia Marina between the late 1920s. Shortly after Italy's entry into World War II in June 1940, she was sunk by British torpedo bombers in Augusta, Sicily, but was later refloated and repaired. She was briefly used in fast troop transport missions to Tunisia until her second and final sinking by Allied aircraft in April 1943.
The action off Bastia was a naval battle fought on 9 September 1943 off Corsica's principal port of Bastia in the Tyrrhenian Sea, part of the Mediterranean Sea. It was one of the few successful Italian reactions to Operation Achse, and one of the first acts of resistance by the Italian armed forces against Nazi Germany after the armistice of Cassibile.
Tifone was a Ciclone-class torpedo boat that served with the Italian Navy during the Second World War. The vessel entered service on 11 July 1942 and was scuttled on 7 May 1943 at Korbous, Tunisia. She escorted the last Axis convoy to reach Africa in World War II.
Freccia was the lead ship of her class of four destroyers built for the Regia Marina in the early 1930s. Completed in 1931, she served in World War II and previous conflicts.
Pegaso was a torpedo boat and an escort aviso of the Italian Regia Marina. She was one of the most successful Axis anti-submarine warships of World War II.
