6 Inch Siege Gun M1877
The 6-inch siege gun model 1877 (russian: 6-дюймовая осадная пушка образца 1877 года) was a Russian fortress gun, siege gun and coastal defense gun. It was used in the Russo-Japanese War, World War I, and the Russian Civil War. The successor states of the Russian Empire also inherited a number of M1877 guns. History The M1877 was designed by the Mikhailovsky Artillery Academy in 1875 and produced by Obukhov State Plant in Saint Petersburg and later at Motovilikha Plants in Perm that entered service in 1877. The M1877 was fairly conventional for its time and most nations had similar guns. However, its lack of recoil mechanism made it dated by the time the First World War broke out. Most were assigned to defend Russian forts when the First World War broke out. The M1877 was designed with the lessons of the Franco-Prussian and Russo-Turkish war in mind where field guns with smaller shells and limited elevation had difficulty overcoming fortif ...

Siege Gun
Siege artillery (also siege guns or siege cannons) are heavy guns designed to bombard fortifications, cities, and other fixed targets. They are distinct from field artillery and are a class of siege weapon capable of firing heavy cannonballs or shells that required enormous transport and logistical support to operate. They lacked mobility and thus were rarely useful in more mobile warfare situations, generally having been superseded by heavy howitzers (towed and self-propelled artillery), strategic bomber aircraft, surface-to-surface missiles, ballistic missiles, cruise missiles and multiple rocket launchers in modern warfare.

Field Gun
A field gun is a field artillery piece. Originally the term referred to smaller guns that could accompany a field army on the march, that when in combat could be moved about the battlefield in response to changing circumstances ( field artillery), as opposed to guns installed in a fort (garrison artillery or coastal artillery), or to siege cannons and mortars which are too large to be moved quickly, and would be used only in a prolonged siege. Perhaps the most famous use of the field gun in terms of advanced tactics was Napoleon Bonaparte's use of very large wheels on the guns that allowed them to be moved quickly even during a battle. By moving the guns from point-to-point during a battle, enemy formations could be broken up to be handled by the infantry or cavalry wherever they were massing, dramatically increasing the overall effectiveness of the attack. World War I As the evolution of artillery continued, almost all guns of any size became capable of being moved at some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horse Artillery
Horse artillery was a type of light, fast-moving, and fast-firing artillery which provided highly mobile fire support, especially to cavalry units. Horse artillery units existed in armies in Europe, the Americas, and Asia, from the early 17th to the mid-20th century. A precursor of modern self-propelled artillery, it consisted of light cannons or howitzers attached to light but sturdy two-wheeled carriages called caissons or limbers, with the individual crewmen riding on horses. This was in contrast to the rest of the field artillery, which were also horse-drawn but whose gunners were normally transported seated on the gun carriage, wagons or limbers. Tactics Once in position, horse artillery crews were trained to quickly dismount, deploy or unlimber their guns (detach them from their caissons), then rapidly fire grapeshot, shells or round shot at the enemy. They could then just as rapidly limber-up (reattach the guns to the caissons), remount, and be ready to move to a new pos ...

Cavalry
Historically, cavalry (from the French word ''cavalerie'', itself derived from "cheval" meaning "horse") are soldiers or warriors who fight mounted on horseback. Cavalry were the most mobile of the combat arms, operating as light cavalry in the roles of reconnaissance, screening, and skirmishing in many armies, or as heavy cavalry for decisive shock attacks in other armies. An individual soldier in the cavalry is known by a number of designations depending on era and tactics, such as cavalryman, horseman, trooper, cataphract, knight, hussar, uhlan, mamluk, cuirassier, lancer, dragoon, or horse archer. The designation of ''cavalry'' was not usually given to any military forces that used other animals for mounts, such as camels or elephants. Infantry who moved on horseback, but dismounted to fight on foot, were known in the early 17th to the early 18th century as '' dragoons'', a class of mounted infantry which in most armies later evolved into standard cavalry while ...

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 ...

Trunnion
A trunnion (from Old French "''trognon''", trunk) is a cylindrical protrusion used as a mounting or pivoting point. First associated with cannons, they are an important military development. Alternatively, a trunnion is a shaft that positions and supports a tilting plate. This is a misnomer, as in reality it is a cradle for the true trunnion. In mechanical engineering (see the trunnion bearing section below), it is one part of a rotating joint where a shaft (the trunnion) is inserted into (and turns inside) a full or partial cylinder. Medieval history In a cannon, the trunnions are two projections cast just forward of the center of mass of the cannon and fixed to a two-wheeled movable gun carriage. As they allowed the muzzle to be raised and lowered easily, the integral casting of trunnions is seen by military historians as one of the most important advances in early field artillery. With the creation of larger and more powerful siege guns in the early 15th century, a n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artillery Tractor
An artillery tractor, also referred to as a gun tractor, is a specialized heavy-duty form of tractor unit used to tow artillery pieces of varying weights and calibres. It may be 6x6, wheeled, continuous track, tracked, or half-tracked. Traction There are two main types of artillery tractors, depending on the type of traction: wheeled and tracked. * Wheeled tractors are usually variations of truck, lorries adapted for military service. * Tracked tractors run on continuous track; in some cases are built on a modified tank chassis with the superstructure replaced with a compartment for the gun crew or ammunition. In addition, half-track tractors were used in the interwar period and in World War II, especially by the Wehrmacht. This type of tractor was mostly discontinued postwar. History World War I The first artillery tractors were designed prior to the outbreak of World War I, often based on agricultural machines such as the Holt tractor. Such vehicles allowed the tact ...

Limbers And Caissons
A limber is a two-wheeled cart designed to support the trail of an artillery piece, or the stock of a field carriage such as a caisson or traveling forge, allowing it to be towed. The trail is the hinder end of the stock of a gun-carriage, which rests or slides on the ground when the carriage is unlimbered. A caisson () is a two-wheeled cart designed to carry artillery ammunition; the British term is "ammunition wagon". Caissons are also used to bear the casket of the deceased in some state and military funerals in certain Western cultures, including the United States. Before the 19th century As artillery pieces developed trunnions and were placed on carriages featuring two wheels and a trail, a limber was devised. This was a simple cart with a pintle. When the piece was to be towed, it was raised over the limber and then lowered, with the pintle fitting into a hole in the trail. Horses or other draft animals were harnessed in single file to haul the limber. There was no p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grouser
Grousers are devices intended to increase the traction of continuous tracks, especially in loose material such as soil or snow. This is done by increasing contact with the ground with protrusions, similar to conventional tire treads, and analogous to athletes' cleated shoes. On tanks and armoured vehicles, grousers are usually pads attached to the tracks; but on construction vehicles they may take the form of flat plates or bars. Similar traction-improving patterns have been implemented on the surface of the wheels on tractors. These include strakes, where material is removed from the surface of the wheel to achieve protrusion; cleats, with spikes instead of straight bars; and lugs with raised rubber on a tire tread. Variations Developed during World War I, external track extensions – often called "grousers" or "duckbills" – were added to the outside edges of the trackshoes on armored fighting vehicles such as tanks, widening the track for improved performance ...

Parapet
A parapet is a barrier that is an extension of the wall at the edge of a roof, terrace, balcony, walkway or other structure. The word comes ultimately from the Italian ''parapetto'' (''parare'' 'to cover/defend' and ''petto'' 'chest/breast'). Where extending above a roof, a parapet may simply be the portion of an exterior wall that continues above the edge line of the roof surface, or may be a continuation of a vertical feature beneath the roof such as a fire wall or party wall. Parapets were originally used to defend buildings from military attack, but today they are primarily used as guard rails, to conceal rooftop equipment, reduce wind loads on the roof, and to prevent the spread of fires. In the Bible the Hebrews are obligated to build a parapet on the roof of their houses to prevent people falling (Deuteronomy 22:8). Parapet types Parapets may be plain, embattled, perforated or panelled, which are not mutually exclusive terms. *Plain parapets are upward extensions of ...

Pood
''Pood'' ( rus, пуд, r=pud, p=put, plural: or ) is a unit of mass equal to 40 ''funt'' (, Russian pound). Since 1899 it is set to approximately 16.38 kilograms (36.11 pounds). It was used in Russia, Belarus, and Ukraine. ''Pood'' was first mentioned in a number of 12th-century documents. Unlike '' funt'', which came at least in the 14th century from gmh, phunt, orv, пудъ (formerly written * ) is a much older borrowing from Late Latin "pondo", from Classical "pondus". Use in the past and present Together with other units of weight of the Imperial Russian weight measurement system, the USSR officially abolished the ''pood'' in 1924. But the term remained in widespread use at least until the 1940s. In his 1953 short story "Matryona's Place", Aleksandr Solzhenitsyn presents the ''pood'' as still in use amongst the Khrushchev-era Soviet peasants. Its usage is preserved in modern Russian in certain specific cases, e.g., in reference to sports weights, such as traditi ...

Sliding Block Breech
A breechblock (or breech block) is the part of the firearm action that closes the breech of a breech loading weapon (whether small arms or artillery) before or at the moment of firing. It seals the breech and contains the pressure generated by the ignited propellant. Retracting the breechblock allows the chamber to be loaded with a cartridge. Breechblocks are categorised by the type or design of the mechanism by which it is locked or closed for firing. The firearm action more fully refers to the mechanism by which the operator actuates the opening and closing of the breech. Variants A way of closing the breech or chamber is an essential part of any breech-loading weapon or firearm. Perhaps the simplest way of achieving this is a break-action, in which the barrel, forestock and breech pivot on a hinge that joins the front assembly to the rear of the firearm, incorporating the rear of the breech, the butt and usually, the trigger mechanism. A breechblock is a separate co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
