Re Umberto-class Ironclad
The ''Re Umberto'' class were a group of three ironclad battleships built for the Italian Navy in the 1880s and 1890s. The ships—, , and —were built as the culmination of a major naval expansion program begun in the 1870s following Italy's defeat at the Battle of Lissa in 1866. The ''Re Umberto''s incorporated several innovations over previous Italian designs, including a more efficient arrangement of the main battery, installation of wireless telegraphs, and in ''Sardegna'', the first use of triple-expansion steam engines in an Italian capital ship. Designed by Benedetto Brin, they retained the very thin armor protection and high top speeds of his earlier designs. All three ships served in the Active Squadron for the first decade of their careers, which proved to be uneventful. They were transferred to the Reserve Squadron in 1905, and by the outbreak of the Italo-Turkish War in 1911, they were serving as training ships. They provided fire support to Italian troops fighti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conning Tower
A conning tower is a raised platform on a ship or submarine, often armored, from which an officer in charge can conn the vessel, controlling movements of the ship by giving orders to those responsible for the ship's engine, rudder, lines, and ground tackle. It is usually located as high on the ship as practical, to give the conning team good visibility of the entirety of the ship, ocean conditions, and other vessels. The naval term "conn" may derive from the Middle English ''conne'' (study, become acquainted with) or French ''conduire'' from Latin ''conducere'' (conduct). Surface ships On surface ships, the conning tower was a feature of all battleships and armored cruisers from about 1860 to the early years of World War II. Located at the front end of the superstructure, the conning tower was a heavily armored cylinder, with tiny slit windows on three sides providing a reasonable field of view. Designed to shield just enough personnel and devices for navigation during battle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tripoli, Libya
Tripoli (; ar, طرابلس الغرب, translit= Ṭarābulus al-Gharb , translation=Western Tripoli) is the capital and largest city of Libya, with a population of about 1.1 million people in 2019. It is located in the northwest of Libya on the edge of the desert, on a point of rocky land projecting into the Mediterranean Sea and forming a bay. It includes the port of Tripoli and the country's largest commercial and manufacturing center. It is also the site of the University of Tripoli. The vast barracks, which includes the former family estate of Muammar Gaddafi, is also located in the city. Colonel Gaddafi largely ruled the country from his residence in this barracks. Tripoli was founded in the 7th century BC by the Phoenicians, who gave it the Libyco-Berber name ( xpu, 𐤅𐤉𐤏𐤕, ) before passing into the hands of the Greek rulers of Cyrenaica as Oea ( grc-gre, Ὀία, ). Due to the city's long history, there are many sites of archeological signi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Libya
Libya (; ar, ليبيا, Lībiyā), officially the State of Libya ( ar, دولة ليبيا, Dawlat Lībiyā), is a country in the Maghreb region in North Africa.

Naval Gunfire Support
Naval gunfire support (NGFS) (also known as shore bombardment) is the use of naval artillery to provide fire support for amphibious assault and other troops operating within their range. NGFS is one of a number of disciplines encompassed by the term ''naval fires''. Modern naval gunfire support is one of the three main components of amphibious warfare assault operations support, along with aircraft and ship-launched land-attack missiles. Shipborne guns have been used against shore defences since medieval naval warfare. Tactics NGFS is classified into two types: direct fire, where the ship has line of sight with the target (either visually or through the use of radar), and indirect fire, which, to be accurate, requires an artillery observer to adjust fire. When on the gun line, ships are particularly vulnerable to attack from aircraft coming from a landward direction and flying low to avoid radar detection, or from submarines due to a predictable and steady (non-evasive) cou ...

Training Ship
A training ship is a ship used to train students as sailors. The term is mostly used to describe ships employed by navies to train future officers. Essentially there are two types: those used for training at sea and old hulks used to house classrooms. The hands-on aspect provided by sail training has also been used as a platform for everything from semesters at sea for undergraduate oceanography and biology students, marine science and physical science for high school students, to character building for at-risk youths.

Italo-Turkish War
The Italo-Turkish or Turco-Italian War ( tr, Trablusgarp Savaşı, "Tripolitanian War", it, Guerra di Libia, "War of Libya") was fought between the Kingdom of Italy and the Ottoman Empire from 29 September 1911, to 18 October 1912. As a result of this conflict, Italy captured the Ottoman Tripolitania Vilayet, of which the main sub-provinces were Fezzan, Cyrenaica, and Tripoli itself. These territories became the colonies of Italian Tripolitania and Cyrenaica, which would later merge into Italian Libya. During the conflict, Italian forces also occupied the Dodecanese islands in the Aegean Sea. Italy agreed to return the Dodecanese to the Ottoman Empire in the Treaty of Ouchy in 1912. However, the vagueness of the text, combined with subsequent adverse events unfavourable to the Ottoman Empire (the outbreak of the Balkan Wars and World War I), allowed a provisional Italian administration of the islands, and Turkey eventually renounced all claims on these islands in Article ...

Benedetto Brin
Benedetto Brin (17 May 1833 in Turin, Piedmont24 May 1898 in Rome, Lazio) was an Italian naval administrator and politician. He played a major role in modernizing and expanding the Italian (Royal Navy) from the 1870s to the 1890s, designing several major classes of warships, including the large ironclad warships of the , , and es, the pre-dreadnought battleships of the and es, and the armored cruisers of the and es. His contributions to Italian naval power were marked by the naming of the second ''Regina Margherita''-class battleship as , among other commemorations. Biography Born in Turin, he worked with distinction as a naval engineer until the age of forty. In 1873, Admiral Simone Antonio Saint-Bon, Italy's Naval Minister, appointed him undersecretary of state. The two men collaborated on major projects: Saint-Bon conceived a type of ship, Brin made the plans and directed its construction. On the advent of the Left to power in 1876, Brin was appointed Naval Minister by A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Capital Ship
The capital ships of a navy are its most important warships; they are generally the larger ships when compared to other warships in their respective fleet. A capital ship is generally a leading or a primary ship in a naval fleet. Strategic implications There is usually no formal criterion for the classification, but it is a useful concept in naval strategy; for example, it permits comparisons between relative naval strengths in a theatre of operations without the need for considering specific details of tonnage or gun diameters. A notable example of this is the Mahanian doctrine, which was applied in the planning of the defence of Singapore in World War II, where the Royal Navy had to decide the allocation of its battleships and battlecruisers between the Atlantic and Pacific theatres. The Mahanian doctrine was also applied by the Imperial Japanese Navy, leading to its preventive move to attack Pearl Harbor and the battleships of the U.S. Pacific Fleet. The naval nature of ...

Triple-expansion Engine
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure ''(HP)'' cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure ''(LP)'' cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a ...

Wireless Telegraphy
Wireless telegraphy or radiotelegraphy is transmission of text messages by radio waves, analogous to electrical telegraphy using cables. Before about 1910, the term ''wireless telegraphy'' was also used for other experimental technologies for transmitting telegraph signals without wires. In radiotelegraphy, information is transmitted by pulses of radio waves of two different lengths called "dots" and "dashes", which spell out text messages, usually in Morse code. In a manual system, the sending operator taps on a switch called a telegraph key which turns the transmitter on and off, producing the pulses of radio waves. At the receiver the pulses are audible in the receiver's speaker as beeps, which are translated back to text by an operator who knows Morse code. Radiotelegraphy was the first means of radio communication. The first practical radio transmitters and receivers invented in 1894–1895 by Guglielmo Marconi used radiotelegraphy. It continued to be the only type of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Lissa (1866)
The Battle of Lissa (or Battle of Vis) ( hr, Bitka kod Visa) took place on 20 July 1866 in the Adriatic Sea near the Dalmatian island of Vis () and was a significant victory for an Austrian Empire force over a numerically superior Italian force. It was the first major sea battle between ironclads and one of the last to involve deliberate ramming. The Italian navy fired roughly 1450 shots during the engagement, but failed to sink any Austrian ship while losing two ironclads. One of the main reasons for this poor performance was internal rivalry between the Italian fleet commanders: for example, Italian Vice Admiral Albini, with his ships, did not engage the enemy during the battle. The engagement was made up of several small battles: the main battle was between seven Austrian and twelve Italian ironclads and showed the ability of Austrian commander Tegetthoff to divide his more numerous opponents and then destroy the isolated ironclads. Background The battle occurred as part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
