Italian Cruiser Quarto
''Quarto'' was a unique protected cruiser built by the Italian ''Regia Marina'' (Royal Navy) in the 1910s. Her keel was laid in November 1909, she was launched in August 1911, and was completed in March 1913. She was the first Italian cruiser to be equipped with steam turbines, which gave her a top speed of . Her high speed was a requirement for the role in which she was designed to serve: a scout for the main Italian fleet. ''Quarto'' was based at Brindisi during World War I; she saw action once, during an attack by the Austro-Hungarian Navy on transports operating in the southern Adriatic. She engaged the Austro-Hungarian cruiser but neither ship was damaged and both sides withdrew. ''Quarto'' served briefly in East Asian waters in the early 1930s, and supported Italian forces during the Second Italo-Abyssinian War in 1936. The following year she served as the flagship of the Italian forces participating in the non-intervention patrols during the Spanish Civil War; here ...

Quarto Illustration
Quarto (abbreviated Qto, 4to or 4º) is the format of a book or pamphlet produced from full sheets printed with eight pages of text, four to a side, then folded twice to produce four leaves. The leaves are then trimmed along the folds to produce eight book pages. Each printed page presents as one-fourth size of the full sheet. The earliest known European printed book is a quarto, the '' Sibyllenbuch'', believed to have been printed by Johannes Gutenberg in 1452–53, before the Gutenberg Bible, surviving only as a fragment. Quarto is also used as a general description of size of books that are about 12 inches (30 cm) tall, and as such does not necessarily indicate the actual printing format of the books, which may even be unknown as is the case for many modern books. These terms are discussed in greater detail in book sizes. Quarto as format A quarto (from Latin , ablative form of , fourth) is a book or pamphlet made up of one or more full sheets of paper on which 8 pages o ...

Adriatic Sea
The Adriatic Sea () is a body of water separating the Italian Peninsula from the Balkan Peninsula. The Adriatic is the northernmost arm of the Mediterranean Sea, extending from the Strait of Otranto (where it connects to the Ionian Sea) to the northwest and the Po Valley. The countries with coasts on the Adriatic are Albania, Bosnia and Herzegovina, Croatia, Italy, Montenegro, and Slovenia. The Adriatic contains more than 1,300 islands, mostly located along the Croatian part of its eastern coast. It is divided into three basins, the northern being the shallowest and the southern being the deepest, with a maximum depth of . The Otranto Sill, an underwater ridge, is located at the border between the Adriatic and Ionian Seas. The prevailing currents flow counterclockwise from the Strait of Otranto, along the eastern coast and back to the strait along the western (Italian) coast. Tidal movements in the Adriatic are slight, although larger amplitudes are known to occur occasi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lieutenant Commander
Lieutenant commander (also hyphenated lieutenant-commander and abbreviated Lt Cdr, LtCdr. or LCDR) is a commissioned officer rank in many navies. The rank is superior to a lieutenant and subordinate to a commander. The corresponding rank in most armies and air forces is major, and in the Royal Air Force and other Commonwealth air forces is squadron leader. The NATO rank code is mostly OF-3. A lieutenant commander is a department officer or the executive officer ( second-in-command) on many warships and smaller shore installations, or the commanding officer of a smaller ship/installation. They are also department officers in naval aviation squadrons. Etymology Most Commonwealth and other navies address lieutenant commanders by their full rank or the positions they occupy ("captain" if in command of a vessel). The United States Navy, however, addresses officers by their full rank or the higher grade of the rank. For example, oral communications in formal and informal s ...

Light Cruiser
A light cruiser is a type of small or medium-sized warship. The term is a shortening of the phrase "light armored cruiser", describing a small ship that carried armor in the same way as an armored cruiser: a protective belt and deck. Prior to this smaller cruisers had been of the protected cruiser model, possessing armored decks only. While lighter and smaller than other contemporary ships they were still true cruisers, retaining the extended radius of action and self-sufficiency to act independently around the world. Through their history they served in a variety of roles, primarily as convoy escorts and destroyer command ships, but also as scouts and fleet support vessels for battle fleets. Origins and development The first small steam-powered cruisers were built for the British Royal Navy with HMS ''Mercury'' launched in 1878. Such second and third class protected cruisers evolved, gradually becoming faster, better armed and better protected. Germany took a lead in small crui ...

Crossing The T
Crossing the ''T'' or capping the ''T'' is a classic naval warfare tactic used from the late 19th to the mid-20th centuries in which a line of warships crosses in front of a line of enemy ships to allow the crossing line to bring all their guns to bear while it receives fire from only the forward guns of the enemy. It became possible to bring all of a ship's main guns to bear only in the late 19th and the early 20th centuries, with the advent of steam-powered battleships with rotating gun turrets, which were able to move faster and turn more quickly than sailing ships, which had fixed guns facing sideways. The tactic became largely obsolete with the introduction of missiles and aircraft as long-range strikes are less dependent on the direction the ships are facing. Tactics When going into battle, ships would assume a battle line formation called "line astern", in which one vessel follows another in one or more parallel lines. This allows each ship to fire over wide arcs witho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russo-Japanese War
The Russo-Japanese War ( ja, 日露戦争, Nichiro sensō, Japanese-Russian War; russian: Ру́сско-япóнская войнá, Rússko-yapónskaya voyná) was fought between the Empire of Japan and the Russian Empire during 1904 and 1905 over rival imperial ambitions in Manchuria and the Korean Empire. The major theatres of military operations were located in Liaodong Peninsula and Mukden in Southern Manchuria, and the Yellow Sea and the Sea of Japan. Russia sought a warm-water port on the Pacific Ocean both for its navy and for maritime trade. Vladivostok remained ice-free and operational only during the summer; Port Arthur, a naval base in Liaodong Province leased to Russia by the Qing dynasty of China from 1897, was operational year round. Russia had pursued an expansionist policy east of the Urals, in Siberia and the Far East, since the reign of Ivan the Terrible in the 16th century. Since the end of the First Sino-Japanese War in 1895, Japan had feared Russian en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire-control System
A fire-control system (FCS) is a number of components working together, usually a gun data computer, a director, and radar, which is designed to assist a ranged weapon system to target, track, and hit a target. It performs the same task as a human gunner firing a weapon, but attempts to do so faster and more accurately. Naval based fire control Origins The original fire-control systems were developed for ships. The early history of naval fire control was dominated by the engagement of targets within visual range (also referred to as direct fire). In fact, most naval engagements before 1800 were conducted at ranges of . Even during the American Civil War, the famous engagement between and was often conducted at less than range. Rapid technical improvements in the late 19th century greatly increased the range at which gunfire was possible. Rifled guns of much larger size firing explosive shells of lighter relative weight (compared to all-metal balls) so greatly increa ...

MT Explosive Motorboat
The explosive motorboat MT (''Motoscafo da Turismo'') also known as ''barchino'' (Italian for "little boat"), was a series of small explosive motor boats developed by the Italian Royal Navy, which was based on its predecessors, the prototype boat MA (''Motoscafo d'Assalto'') and the MAT (''Motoscafo Avio Trasportato''), an airborne prototype. Explosive motorboats were designed to make a silent approach to a moored warship, set a collision course and run into full gear until the last 200 or 100 yards to the target, when the pilot would eject after blocking the rudder. At impact, the hull would be broken amidships by a small explosive charge, sinking the boat and the warhead, which was fitted with a water-pressure fuse set to go off at a depth of one metre. By the end of September 1938 the Navy Department ordered six explosive boats. The one-pilot vessels were built by the companies Baglietto of Varazze and CABI of Milan, which was also to supply the engines.Fock, Harald (1996). ''Mar ...

Human Torpedo
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 name was commonly used to refer to the weapons that Italy, and later (with a larger version) Britain, deployed in the Mediterranean and used to attack ships in enemy harbors. The human torpedo concept has occasionally been used by recreational divers, although this use is closer to midget submarines. History of common wartime models The concept of a small, manned submarine carrying a bomb was developed and patented by a British naval officer in 1909, but was never used during the First World War. The Italian Navy experimented with a primitive tiny sub (Mignatta) carrying two men and a limpet mine: this craft successfully sank Austro-Hungarian battleship SMS ''Viribus Unitis'' on 1 November 1918. The first truly practical human to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Register
A Navy Directory, formerly the Navy List or Naval Register is an official list of naval officers, their ranks and seniority, the ships which they command or to which they are appointed, etc., that is published by the government or naval authorities of a country. Background The Navy List fulfills an important function in international law in that warships are required by article 29 of the United Nations Convention on the Law of the Sea to be commanded by a commissioned officer whose name appears in the appropriate service list. Past copies of the Navy List are also important sources of information for historians and genealogists. The Navy List for the Royal Navy is no longer published in hard-copy. The Royal Navy (United Kingdom) publishes annual lists of active and reserve officers, and biennial lists of retired officers. As of 2015, the Navy List of the Royal Navy has been renamed as the 'Navy Directory'. The equivalent in the United States Navy is the Naval Register, whic ...

Republican Faction (Spanish Civil War)
The Republican faction ( es, Bando republicano), also known as the Loyalist faction () or the Government faction (), was the side in the Spanish Civil War of 1936 to 1939 that supported the government of the Second Spanish Republic against the Nationalist faction of the military rebellion. The name Republicans () was mainly used by its members and supporters, while its opponents used the term ''Rojos'' (Reds) to refer to this faction due to its left-leaning ideology, including far-left communist and anarchist groups, and the support it received from the Soviet Union. At the beginning of the war, the Republicans outnumbered the Nationalists by ten-to-one, but by January 1937 that advantage had dropped to four-to-one. Foreign support The Republican faction hardly received external support from the Allied powers of World War II, due to the International Non-Intervention Committee. The support of the USSR stands out, fundamentally. Together with Mexico, France and Poland at the be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spanish Civil War
The Spanish Civil War ( es, Guerra Civil Española)) or The Revolution ( es, La Revolución, link=no) among Nationalists, the Fourth Carlist War ( es, Cuarta Guerra Carlista, link=no) among Carlists, and The Rebellion ( es, La Rebelión, link=no) or The Uprising ( es, La Sublevación, link=no) among Republicans. was a civil war in Spain fought from 1936 to 1939 between the Republicans and the Nationalists. Republicans were loyal to the left-leaning Popular Front government of the Second Spanish Republic, and consisted of various socialist, communist, separatist, anarchist, and republican parties, some of which had opposed the government in the pre-war period. The opposing Nationalists were an alliance of Falangists, monarchists, conservatives, and traditionalists led by a military junta among whom General Francisco Franco quickly achieved a preponderant role. Due to the international political climate at the time, the war had many facets and was variously viewed as cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
