Ordóñez Guns
Ordóñez guns are a type of coastal artillery that Salvador Diaz Ordóñez, an artillery officer in the Spanish Army, designed in the late 19th century. Most of the models were field guns, but some were howitzers. The guns ranged in caliber from 150mm (5.9") to 305mm (12"). They were made in Spain, at the Trubia Arms Factory (Fábrica de armas de Trubia), in Asturias, and the Spanish installed them in forts and batteries at home, for instance at Ceuta, and throughout their empire, in Puerto Rico, Cuba, and the Philippines. The Ordóñez guns appear to have been used for protecting Spain's colonies; reportedly the Spanish generally reserved the higher quality, and much more expensive, Hontoria guns for the defense of Spain. Although they have been obsolete for more than a century, a few Ordóñez guns have survived to the present as historical artifacts. There is one at Santa Clara Battery in Havana, a second, heavily damaged by the explosion of a shell, and brought from Subic Ba ...

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Krupp
The Krupp family (see pronunciation), a prominent 400-year-old German dynasty from Essen, is notable for its production of steel, artillery, ammunition and other armaments. The family business, known as Friedrich Krupp AG (Friedrich Krupp AG Hoesch-Krupp after acquiring Hoesch AG in 1991 and lasting until 1999), was the largest company in Europe at the beginning of the 20th century, and was the premier weapons manufacturer for Germany in both world wars. Starting from the Thirty Years' War until the end of the Second World War, it produced battleships, U-boats, tanks, howitzers, guns, utilities, and hundreds of other commodities. The dynasty began in 1587 when trader Arndt Krupp moved to Essen and joined the merchants' guild. He bought and sold real estate, and became one of the city's richest men. His descendants produced small guns during the Thirty Years' War and eventually acquired fulling mills, coal mines and an iron forge. During the Napoleonic Wars, Friedrich Kr ...

Philippine–American War
The Philippine–American War or Filipino–American War ( es, Guerra filipina-estadounidense, tl, Digmaang Pilipino–Amerikano), previously referred to as the Philippine Insurrection or the Tagalog Insurgency by the United States, was an armed conflict between the First Philippine Republic and the United States that started on February 4, 1899, and ended on July 2, 1902. The conflict arose in 1898 when the United States, rather than acknowledging the Philippines' Philippine Declaration of Independence, declaration of independence, annexed the Philippines under the Treaty of Paris (1898), Treaty of Paris at the conclusion of the Spanish–American War. The war can be seen as a continuation of the Philippine struggle for independence that began in 1896 with the Philippine Revolution against Spanish East Indies, Spanish rule. Fighting erupted between forces of the United States and those of the Philippine Republic on February 4, 1899, in what became known as the Battle of Manila ...

Railway Gun
A railway gun, also called a railroad gun, is a large artillery piece, often surplus naval artillery, mounted on, transported by, and fired from a specially designed railroad car, railway wagon. Many countries have built railway guns, but the best-known are the large Krupp-built pieces used by German Reich, Germany in World War I and World War II. Smaller guns were often part of an armoured train. Only able to be moved where there were good tracks, which could be destroyed by artillery bombardment or airstrike, railway guns were phased out after World War II. Design considerations The design of a railway gun has three firing issues over and above those of an ordinary artillery piece to consider. Namely how the gun is going to be traversed – i.e. moved from side to side to aim; how the horizontal component of the recoil force will be absorbed by the gun's carriage and how the vertical recoil force will be absorbed by the ground. Methods of traverse The first method of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Águilas
Águilas () is a Municipalities of Spain, municipality and seaport of southeastern Spain, in the province of Region of Murcia, Murcia. It is situated at the southern end of Murcia's Mediterranean Sea, Mediterranean coastline, otherwise known as the Costa Cálida, near the border with the Almería (province), Province of Almería.

Hydraulic Recoil Mechanism
A hydraulic recoil mechanism is a way of limiting the effects of recoil and adding to the accuracy and firepower of an artillery piece. Description The usual recoil system in modern quick-firing guns is the hydro-pneumatic recoil system. In this system, the barrel is mounted on rails on which it can recoil to the rear, and the recoil is taken up by a cylinder which is similar in operation to an automotive gas-charged shock absorber, and is commonly visible as a cylinder mounted parallel to the barrel of the gun, but shorter and smaller than it. The cylinder contains a charge of compressed air, as well as hydraulic oil; in operation, the barrel's energy is taken up in compressing the air as the barrel recoils backward, then is dissipated via hydraulic damping as the barrel returns forward to the firing position. The recoil impulse is thus spread out over the time in which the barrel is compressing the air, rather than over the much narrower interval of time when the project ...

Charles Ragon De Bange
Charles Ragon de Bange (17 October 1833 – 9 July 1914) was a French artillery officer and Polytechnician. He invented the first effective obturator system for breech-loading artillery, which remains in use. He also designed a system of field guns of various calibers which served the French Army well into World War I: the ''Système de Bange''. Career De Bange breech obturator system Many attempts had been made at developing breech-loading cannons, but had only partial success sealing of the breech. When fired, hot gases and burning gunpowder could escape, losing power and potentially burning the operating crew. Rifles, with smaller loads and thus less stress, were able to use rubber in O-rings as on the Chassepot rifle. The same principle of breech sealing applied on cannons was not as easy to develop. Several materials were able to hold the pressure and heat of cannon fire, but did not expand like rubber, thereby failing to provide a tight seal. The most successful of ...

Montjuïc Castle (Barcelona)
Montjuïc Castle ( ca, Castell de Montjuïc, es, Castillo de Montjuich) is an old military fortress, with roots dating back from 1640, built on top of Montjuïc hill in Barcelona, Catalonia, Spain. It currently serves as a Barcelona municipal facility. History The foundation stone for the basic fortification was laid out in 1640. A year later, in January 1641, the fort saw its first battle, during the Catalan Revolt when the Principality of Catalonia challenged Spain's authority. On orders from the King of Spain, Pedro Fajardo, heading an army of 26,000 men, proceeded to crush the revolt. The Spanish recaptured several cities, but they were defeated at the Battle of Montjuïc by Catalan, led by Francesc de Tamarit. At that battle, Colonel Shane O'Neill or known in Spain as Prince Juan O'Neill, died leading his regiment during the Battle of Montjuic near Barcelona, dying from a musket-ball wound to his chest near the town of Castelldefels. In his honor, the King of Spain gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fort La Mola
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its 'cyclopean' walls). A Greek '' phrourion'' was a fortified collection of buildings used as a military garrison, and is the equivalent of the Roman castellum or English fortress. These constructions mainly served the purpose of a watch tower, to guard certain roads, passes, and borders. Though smaller than a real fortress, they acted ...
