CA Class Midget Submarine
The CA class were a group of midget submarines built for the Italian Navy during World War II. Design These submarines were designed by the Caproni Company and built in great secrecy. They were originally designed for coast defence but later modified as clandestine attack craft similar to the British X craft. Boats Service In 1942, after the United States entered the war, Junio Valerio Borghese, commander of the Decima MAS (the Italian Navy's special operations unit), devised a plan to attack New York Harbor using a CA type midget submarine and commando frogmen. The midget submarine would be transported across the Atlantic by being carried on the deck of a larger submarine. The Italian submarine was chosen for the task and modified at the Italian base in Bordeaux (BETASOM). ''CA 2'' was transported by rail from Italy and trials, which were conducted near La Pallice, were supervised by Borghese himself during late 1942. ''Leonardo Da Vinci'' was sunk in May 1943 before th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caproni
Caproni, also known as ''Società de Agostini e Caproni'' and ''Società Caproni e Comitti'', was an Italian aircraft manufacturer. Its main base of operations was at Taliedo, near Linate Airport, on the outskirts of Milan. Founded by Giovanni Battista "Gianni" Caproni during 1908, the company produced several successful heavy bombers during the First World War. Following the acquisition of several other aviation firms throughout the interwar period, Caproni transformed into a sizable aviation-orientated syndicate, the ''Società Italiana Caproni, Milano''. The majority of its aircraft were bombers and transport aircraft. It played a pioneering role in the development of the Caproni Campini N.1, an experimental aircraft powered by a thermo-jet. It provided large numbers of combat aircraft for the Axis during the Second World War. The firm did not prosper in the postwar era, the Società Italiana Caproni collapsing during 1950. Many of the company's former assets were subsequ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New York Harbor
New York Harbor is at the mouth of the Hudson River where it empties into New York Bay near the East River tidal estuary, and then into the Atlantic Ocean on the east coast of the United States. It is one of the largest natural harbors in the world, and is frequently named the best natural harbor in the world. It is also known as Upper New York Bay, which is enclosed by the New York City boroughs of Manhattan, Brooklyn, and Staten Island and the Hudson County, New Jersey municipalities of Jersey City and Bayonne. The name may also refer to the entirety of New York Bay including Lower New York Bay. Although the United States Board on Geographic Names does not use the term, ''New York Harbor'' has important historical, governmental, commercial, and ecological usages. Overview The harbor is fed by the waters of the Hudson River (historically called the North River as it passes Manhattan), as well as the Gowanus Canal. It is connected to Lower New York Bay by the Narrows, to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Midget Submarines
A midget submarine (also called a mini submarine) is any submarine under 150 tons, typically operated by a crew of one or two but sometimes up to six or nine, with little or no on-board living accommodation. They normally work with mother ships, from which they are launched and recovered and which provide living accommodation for the crew and support staff. Both military and civilian midget submarines have been built. Military types work with surface ships and other submarines as mother ships. Civilian and non-combatant military types are generally called submersibles and normally work with surface ships. Most early submarines would now be considered midget submarines, such as the United States Navy's and the British Royal Navy's (both named for the same designer). Military submarines Uses Midget submarines are best known for harbor penetration, although only two World War II boats, the British X-craft and the unsuccessful Welman submarine, were specifically designed with t ...

Submarines Of The Regia Marina
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion of spec ...

Italian Submarines Of World War II
The Italian submarine fleet of World War II was the largest in the world at the time, with 116 submarines. It saw action during the Second World War, serving mainly in the Mediterranean. During the conflict 88 submarines, some two-thirds of its total strength, were lost. Construction history The submarine fleet available to the Italian Royal Navy (the ''Regia Marina'') in World War II was the product of a long term build-up during the interwar years, despite the prevailing economic and political pressures of the period. After World War I Italy had a fleet of 47 submarines in various classes; these were mostly obsolescent and she was interested in replacing them. To this end the ''Regia Marina'' made plans for a fleet of vessels in three Types: *Type I ocean-going: *Type 2 coastal/sea-going; *Type 3 mine layers. *The Navy also invested time and resources in midget submarines and underwater special forces. At the same time the major powers were negotiating an arms limitation tre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Italian Armistice
The Armistice of Cassibile was an armistice signed on 3 September 1943 and made public on 8 September between the Kingdom of Italy and the Allies during World War II. It was signed by Major General Walter Bedell Smith for the Allies and Brigade General Giuseppe Castellano for Italy at a conference of generals from both sides in an Allied military camp at Cassibile, in Sicily, which had recently been occupied by the Allies. The armistice was approved by both the Italian King Victor Emmanuel III and Marshal Badoglio, the Prime Minister of Italy at the time. Germany moved rapidly by freeing Benito Mussolini (12 September) and attacking Italian forces in Italy (8–19 September), southern France and the Balkans. The Italian forces were quickly defeated, and most of Italy was occupied by German troops, who established a puppet state, the Italian Social Republic. The king, the Italian government, and most of the navy escaped to territories occupied by the Allies. Background Fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Pallice
La Pallice (also known as ''grand port maritime de La Rochelle'') is the commercial deep-water port of La Rochelle, France. During the Fall of France, on 19 June 1940, approximately 6,000 Polish soldiers in exile under the command of Stanisław Sosabowski arrived at La Pallice, from where they were evacuated to Great Britain - thus able to go on fighting till the end of the war. Under the Nazi Occupation of France, La Pallice was used as a U-boat base () from October 1941 when the 3rd U-boat Flotilla was moved there from its base in Kiel. La Pallice was subject to the allied siege of La Rochelle in 1944–45, which ended with the capitulation of Germany. The large submarine base built at that time still stands largely is not in use. It was used as a backdrop for the film ''Das Boot'' (1981) and ''Raiders of the Lost Ark ''Raiders of the Lost Ark'' is a 1981 American action-adventure film directed by Steven Spielberg and written by Lawrence Kasdan, based on a story by ...

BETASOM
BETASOM (an Italian language acronym of ''Bordeaux Sommergibile'' or ''Sommergibili'') 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. Establishment Axis naval co-operation started after the signing of the Pact of Steel in June 1939 with meetings in Friedrichshafen, Germany, and an agreement to exchange technical information. After the Italian entry into the war and the Fall of France, the Italian Royal Navy established a submarine base at Bordeaux, which was within the German occupation zone. The Italians were allocated a sector of the Atlantic south of Lisbon to patrol. The base was opened in August 1940, and in 1941 the captured French passenger ship was used as a depot ship before being returned to the Vichy French Government in June 1942. Admir ...

Decima MAS
The ''Decima Flottiglia MAS'' (''Decima Flottiglia Motoscafi Armati Siluranti'', also known as ''La Decima'' or Xª MAS) (Italian for "10th Assault Vehicle Flotilla") was an Italian flotilla, with commando frogman unit, of the ''Regia Marina'' (Italian Royal Navy) created during the Fascist regime. The acronym '' MAS'' also refers to various light torpedo boats used by the Regia Marina during World War I and World War II. Decima MAS was active during the Battle of the Mediterranean and took part in a number of daring raids on Allied shipping. These operations involved surface speedboats (such as the raid on Souda Bay), manned torpedoes (the raid on Alexandria) and ''Gamma'' frogmen (against Gibraltar). During the campaign Decima MAS took part in more than a dozen operations which sank or damaged five warships (totalling 72,000 tons) and 20 merchant ships (totalling 130,000 GRT). In 1943, after the Italian dictator Benito Mussolini was ousted, Italy left the Tripartite Pact. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
