General-Admiral-class Cruiser
The ''General-Admiral''-class ships were a pair of armored cruisers built for the Imperial Russian Navy in the early 1870s. They are generally considered as the first true armored cruisers. Design and description Originally classified as armored corvettes, the ''General-Admiral''s were redesignated as semi-armored frigates on 24 March 1875. They were laid out as central battery ironclads with the armament concentrated amidships. The ''General-Admiral''-class ships were long overall. They had a beam of and a draft of . The ships were designed to displace , but displaced as built, an increase of over . The iron-hulled ships were not fitted with a ram and their crew numbered approximately 482 officers and men.Watts, p. 72 The ships had a vertical compound steam engine driving a single two-bladed, propeller, using steam provided by cylindrical boilers. The number of boilers differed between the sisters. ''General-Admiral'' had five that generated a working pressure of so t ...

Armored Cruiser
The armored cruiser was a type of warship of the late 19th and early 20th centuries. It was designed like other types of cruisers to operate as a long-range, independent warship, capable of defeating any ship apart from a battleship and fast enough to outrun any battleship it encountered. For many decades, naval technology had not advanced far enough for designers to produce a cruiser which combined an armored belt with the long range and high speed required to fulfill its mission. For this reason, beginning in the 1880s and 1890s, many navies preferred to build protected cruisers, which only relied on a light armored deck to protect the vital parts of the ship. However, by the late 1880s, the development of modern rapid-fire breech-loading cannon and high-explosive shells made the reintroduction of side armor a necessity. The invention of face-hardened armor in the mid-1890s offered effective protection with less weight than previously. Varying in size, the armored cruiser ...

Mast (sailing)
The mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the centre-line of a ship or boat. Its purposes include carrying sails, spars, and derricks, and giving necessary height to a navigation light, look-out position, signal yard, control position, radio aerial or signal lamp. Large ships have several masts, with the size and configuration depending on the style of ship. Nearly all sailing masts are guyed. Until the mid-19th century, all vessels' masts were made of wood formed from a single or several pieces of timber which typically consisted of the trunk of a conifer tree. From the 16th century, vessels were often built of a size requiring masts taller and thicker than could be made from single tree trunks. On these larger vessels, to achieve the required height, the masts were built from up to four sections (also called masts). From lowest to highest, these were called: lower, top, topgallant, and royal masts. Giving t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alfred, Duke Of Saxe-Coburg And Gotha
Alfred (Alfred Ernest Albert; 6 August 184430 July 1900) was the sovereign duke of Saxe-Coburg and Gotha from 1893 to 1900. He was the second son and fourth child of Queen Victoria and Prince Albert. He was known as the Duke of Edinburgh from 1866 until he succeeded his paternal uncle Ernest II as the reigning Duke of Saxe-Coburg and Gotha in the German Empire. Early life Prince Alfred was born on 6 August 1844 at Windsor Castle to the reigning British monarch, Queen Victoria, and her husband, Prince Albert, the second son of Ernest I, Duke of Saxe-Coburg and Gotha. Nicknamed Affie, he was second in the line of succession to the British throne behind his elder brother, the Prince of Wales. Alfred was baptised by the Archbishop of Canterbury, William Howley, at the Private Chapel in Windsor Castle on 6 September 1844. His godparents were his mother's first cousin, Prince George of Cambridge (represented by his father, the Duke of Cambridge); his paternal aunt, the Duc ...

Old Style And New Style Dates
Old Style (O.S.) and New Style (N.S.) indicate dating systems before and after a calendar change, respectively. Usually, this is the change from the Julian calendar to the Gregorian calendar as enacted in various European countries between 1582 and 1923. In England, Wales, Ireland and Britain's American colonies, there were two calendar changes, both in 1752. The first adjusted the start of a new year from Lady Day (25 March) to 1 January (which Scotland had done from 1600), while the second discarded the Julian calendar in favour of the Gregorian calendar, removing 11 days from the September 1752 calendar to do so.Spathaky, MikOld Style and New Style Dates and the change to the Gregorian Calendar "Before 1752, parish registers, in addition to a new year heading after 24th March showing, for example '1733', had another heading at the end of the following December indicating '1733/4'.

Sredne-Nevskiy Shipyard
The Middle Neva Shipbuilding Plant (russian: Средне-Невский судостроительный завод, Sredne-Nevskiy sudostroitelnyy zavod) was founded before the end of the 19th century in Saint Petersburg, Russia. In 1917 it employed 17,000 people. It established a branch in Nikolaev in the early years of the 20th century to assemble ships which had been built in St. Petersburg and transported to the Black Sea.Breyer, p. 144 It is part of the United Shipbuilding Corporation. History The Middle Neva shipyard, located near the junction of the Izhora and Neva rivers in the Kolpino district of southern St. Petersburg, is an important builder of mine warfare ships for the Russian navy. The yard probably dates back to 1911, when the Saint Petersburg Metals Plant, then a builder of marine turbines, established a shipyard at Ust-Izhora to build destroyers. Between the world wars the Ust-Izhora yard was limited to the construction of river barges. It was expanded into a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Duke Konstantin Nikolayevich Of Russia
Grand Duke Konstantin Nikolayevich of Russia (21 September 1827 – 25 January 1892) was the Emperor's Viceroy of Poland from 1862 to 1863. Early life Konstantin Nikolayevich was born as the second son of Nicholas I and his wife, Charlotte of Prussia, daughter of Frederick William III of Prussia and his first wife, Louise of Mecklenburg-Strelitz. Biography The Grand Duke was a supporter of the liberal (sometimes referred to as "enlightened") bureaucrats during the period of his brother Alexander II's great reforms. He served as chairman of the Imperial Russian Geographical Society (founded in 1845). The Geographical Society was subordinate to the Ministry of Internal Affairs, which was home to a conspicuous number of , including Nikolai Miliutin. In addition to his support of and participation in the 1861 emancipation of the serfs, the Grand Duke also instituted reforms in the Imperial Russian Navy from 1854.

Ship Naming And Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is t ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artillery Battery
In military organizations, an artillery battery is a unit or multiple systems of artillery, mortar systems, rocket artillery, multiple rocket launchers, surface-to-surface missiles, ballistic missiles, cruise missiles, etc., so grouped to facilitate better battlefield communication and command and control, as well as to provide dispersion for its constituent gunnery crews and their systems. The term is also used in a naval context to describe groups of guns on warships. Land usage Historically the term "battery" referred to a cluster of cannon in action as a group, either in a temporary field position during a battle or at the siege of a fortress or a city. Such batteries could be a mixture of cannon, howitzer, or mortar types. A siege could involve many batteries at different sites around the besieged place. The term also came to be used for a group of cannon in a fixed fortification, for coastal or frontier defence. During the 18th century "battery" began to be used as ...

Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welded, but is more difficult to weld electrically. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name ''wrought'' because it was hammered, rolled, or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is mild steel, also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be hardenable by heating and quenching. Wrought iron is highly refined, with a small amount of silic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterline
The waterline is the line where the hull of a ship meets the surface of the water. Specifically, it is also the name of a special marking, also known as an international load line, Plimsoll line and water line (positioned amidships), that indicates the draft of the ship and the legal limit to which a ship may be loaded for specific water types and temperatures in order to safely maintain buoyancy, particularly with regard to the hazard of waves that may arise. Varying water temperatures will affect a ship's draft, because warm water is less dense than cold water, providing less buoyancy. In the same way, fresh water is less dense than salinated or seawater with a similar lessening effect upon buoyancy. For vessels with displacement hulls, the hull speed is defined by, among other things, the waterline length. In a sailing boat, the waterline length can change significantly as the boat heels, and can dynamically affect the speed of the boat. A waterline can also refer to ...
