The Type 212A is a class of diesel-electric submarine developed by Howaldtswerke-Deutsche Werft AG (HDW) for the German Navy, and the Italian Navy where it is known as the Todaro class. It features diesel propulsion and an additional air-independent propulsion (AIP) system using Siemens proton exchange membrane (PEM) compressed hydrogen fuel cells. The submarines can operate at high speed on diesel power or switch to the AIP system for silent slow cruising, staying submerged for up to three weeks with little exhaust heat. The system is also said to be vibration-free and virtually undetectable.
The Maestrale class is a class of frigates of the Italian Navy. The class is composed of eight vessels, all of which were built by Fincantieri S.p.A., Riva Trigoso, except for Grecale, which was built by Fincantieri S.p.A. – Muggiano, La Spezia.
Human torpedoes or manned torpedoes are a type of diver propulsion vehicle on which the diver rides, generally in a seated position behind a fairing. They were used as secret naval weapons in World War II. The basic concept is still in use.
The Italian Navy is the navy of the Italian Republic. It is one of the four branches of Italian Armed Forces and was formed in 1946 from what remained of the Regia Marina after World War II. As of August 2014, the Italian Navy had a strength of 30,923 active personnel, with approximately 184 vessels in service, including minor auxiliary vessels. It is considered a multiregional and a blue-water navy.
COMSUBIN is the Italian Navy's special operations unit.
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 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.
The Audace-class destroyers were two guided missile destroyers built for the Italian Navy during the Cold War. An improvement of the Impavido class, these ships were designed for area air defence and also had a heavy gun armament. They were fitted with contemporary American radars and sonars, but also, as the next Italian ships, all the modern weapons made by Italian industry of the time, such torpedoes, helicopters and guns. Also some indigenous radars were fitted.
The Impavido class were the second group of destroyers built for the Italian Navy after World War II and the first Italian guided missile destroyers. Similar in performance to the US Navy's Charles F. Adams class, these ships were essentially improved Impetuoso-class vessels, with the after gun-turret being replaced by a Tartar surface-to-air-missile launcher and associated radar.
The San Giorgio class are amphibious transport docks (LPD) built by Fincantieri for the Italian Navy. These ships can carry a battalion of troops, and up to 36 armored vehicles. The stern floodable dock can accommodate three landing craft. The ships are based at the Brindisi naval base on the Adriatic coast.
The Ciclone class were a group of torpedo boats or destroyer escorts built for the Italian Navy which fought in the Second World War. They were modified, slightly heavier, versions of the previous Orsa class, with improved stability and heavier anti-submarine armament. These ships were built as part of the Italian war mobilization programme and completed in 1942–43.
The Gabbiano-class corvettes were a group of 59 vessels built for the Regia Marina of Italy for service during the Second World War. They were built to a war-time design and intended for anti-submarine and escort duties.
Raffaele Rossetti was an Italian engineer and military naval officer who sank the main battleship of the Austro-Hungarian Empire at the end of World War I. He was also a politician of the Italian Republican Party.
Albatros was a submarine chaser of the Regia Marina built in 1930s which served during World War II. Later she was reclassified as a torpedo boat, most likely purely for administrative purposes.
The Sirio class of patrol vessels consists of two units operated by the Italian Navy named Costellazioni II series or Nuove Unità di Pattugliamento d'Altura (NUPA). These vessels were financed by the Italian Department of Transport and Navigation, under law 413/1998, for maritime economic zone surveillance, antipollution, and rescue operations.
The Bergamini class was a class of four frigates operated by the Italian Navy. They entered service in 1961, with the last one being stricken in 1988.
The Generali-class destroyer was a class of Italian destroyers, built as a development of the Rosolino Pilo-class destroyer. They were the last ships of the Regia Marina, fitted with three stacks. In 1929, being obsolete, the units were reclassified as torpedo boats, and in this role served during Second World War.
The Albatros class was a class of eight corvettes designed and built in Italy in the 1950s. Paid for by US funds, they were operated by Italy, Denmark, Indonesia and the Netherlands. The last ships of the class were retired from service in Italy in 1991.
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.
Carabiniere was a frigate operated by the Italian Navy. Launched in 1967, the vessel served in the anti-submarine role during the Cold War until 1992. The ship was then recommissioned as a testing platform for new weapons systems, including Aster, finally retiring in 2008.
