The German Type 212 class, also Italian Todaro class, is a diesel-electric submarine developed by Howaldtswerke-Deutsche Werft AG (HDW) for the German and Italian navies. 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, extremely quiet and virtually undetectable.
USS Volador (SS-490), a Tench-class submarine, was the second ship of the United States Navy to be named for the volador. The contract to build her was awarded to Portsmouth Naval Shipyard in Kittery, Maine, and her keel was laid down on 15 June 1945, but work on her construction was discontinued in January 1946. Her unfinished hulk remained on the ways until August 1947 when construction resumed, now including GUPPY II enhancements to the basic Tench design. Volador was launched on 21 May 1948 sponsored by Mrs. Harriet Rose Morton widow of Commander Dudley W. Morton, and commissioned on 1 October 1948, with Lieutenant Commander Howard A. Thompson in command.
USS Pickerel (SS-524), a Tench-class submarine, was the second ship of the United States Navy to be named for a young or small pike. The contract to build her was awarded to the Boston Naval Shipyard and her keel was laid down on 8 February 1944. She was launched without a christening ceremony on 15 December 1944. After being towed to the Portsmouth Naval Shipyard in Kittery, Maine for completion, she was simultaneously christened and commissioned on 4 April 1949 sponsored by Mrs. John R. Moore and commanded by Lieutenant Commander Paul R. Schratz.
Cavour is an Italian aircraft carrier launched in 2004. She is the flagship of the Italian Navy.
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.
The Nazario Sauro class are diesel-electric submarines operated by the Italian Navy. All boats were built by Fincantieri in Monfalcone.
The Marcello class was a class of nine submarines built in 1937 and 1938 by CRDA in Trieste for the Royal Italian Navy. Two similar submarines built in 1939 at La Spezia by Oto Melara are sometimes considered part of the class. All eleven served in the Mediterranean Sea at the start of the Second World War. After Provana's 1940 sinking, the remaining boats were transferred to the BETASOM Atlantic submarine base at Bordeaux in August 1940. After four boats had been sunk in the Atlantic, Barbarigo and Comandante Cappellini were then selected for conversion to "transport submarines" in order to exchange rare or irreplaceable trade goods with Japan. Cargo capacity of 160 tons reduced reserve buoyancy from 20–25% to 3.5–6%; and armament was reduced to defensive machine guns. Only Dandolo was in operational condition at the end of the war.
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.
Gianfranco Gazzana Priaroggia was an officer in the Italian Royal Navy, and was the highest-scoring Italian submarine captain of World War II.
BETASOM was a submarine base established at Bordeaux, France by the Italian Regia Marina Italiana during World War II. From this base, Italian submarines participated in the Battle of the Atlantic from 1940 to 1943 as part of the Axis anti-shipping campaign against the Allies.
Leonardo da Vinci was a Marconi-class submarine of the Italian navy during World War II. It operated in the Atlantic from September 1940 until its loss in May 1943, and became the top scoring non-German submarine of the entire war.
The Calvi class was a class of three submarines built by Oderno-Terni-Orlando in Genoa for the Royal Italian Navy. The submarines were built in 1935, and all three served in the Mediterranean at the start of the Second World War. The boats were transferred to the BETASOM Atlantic submarine base at Bordeaux in August 1940. In December 1941 the boats were used for a rescue mission of 254 sailors from the sunken German auxiliary cruiser Atlantis. After Calvi had been sunk, Finzi and Tazzoli were selected for conversion to "transport submarines" in order to exchange rare or irreplaceable trade goods with Japan. Cargo capacity of 160 tons reduced reserve buoyancy from 20–25% to 3.5–6%; and armament was reduced to defensive machine guns.
Archimede was a Brin-class submarine built for the Royal Italian Navy during the 1930s.
The Argo-class was a class of two coastal submarines built by Cantieri Riuniti dell'Adriatico in Monfalcone for Portugal but operated by the Royal Italian Navy after Portugal was unable to pay construction costs. The submarines were built in 1936, and both served in the Mediterranean Sea at the start of the Second World War. The boats were transferred to the BETASOM Atlantic submarine base at Bordeaux in 1940, but returned to the Mediterranean in 1941, where both were sunk within a few days of the September 1943 Italian armistice.
The Liuzzi class was a class of four submarines built by Tosi in Taranto for the Royal Italian Navy. The submarines were built in 1939 and began their Second World War service in the Mediterranean Sea, where Liuzzi was sunk. The three surviving boats were transferred to the BETASOM Atlantic submarine base at Bordeaux in 1940. After Tarantini was sunk, Bagnolini and Giuliani were selected for conversion to "transport submarines" in order to exchange rare or irreplaceable trade goods with Japan. Cargo capacity of 160 tons reduced reserve buoyancy from 20–25% to 3.5–6%; and armament was reduced to defensive machine guns.
Gianfranco Gazzana Priaroggia was the name of at least two ships of the Italian Navy named in honour of Gianfranco Gazzana-Priaroggia and may refer to:
Leonardo da Vinci was a Sauro-class submarine of the Italian Navy.
Giuliano Prini was a Sauro-class submarine of the Italian Navy.
Primo Longobardo was a Sauro-class submarine of the Italian Navy.
