Mortar (weapon)

The Ming dynasty, officially the Great Ming, was an imperial dynasty of China, ruling from 1368 to 1644 following the collapse of the Mongol-led Yuan dynasty. The Ming dynasty was the last imperial dynasty of China with a ruling elite of Han Chinese, the majority ethnic group in China. Although the primary capital of Beijing fell in 1644 to a rebellion led by Li Zicheng, numerous rump regimes ruled by remnants of the Ming imperial family—collectively called the Southern Ming—survived until 1662.

Hu dun pao (虎蹲砲) is the name of two different missile weapons in Chinese history. In the Song dynasty (960–1279), it was a trebuchet and its name is translated into English as Crouching Tiger Trebuchet; in the Ming dynasty (1368–1644), the name was given to a type of bombard and it is known in English as Crouching Tiger Cannon.

The fall of Constantinople, also known as the conquest of Constantinople, was the capture of the capital of the Byzantine Empire by the Ottoman Empire. The city was captured on 29 May 1453 as part of the culmination of a 53-day siege which had begun on 6 April.

The Ottoman Turks, were a Turkic ethnic group. They founded the Ottoman Empire in the Early Modern Era and remained sociopolitically the most dominant group in the Empire for the duration.

The Acropolis of Athens is an ancient citadel located on a rocky outcrop above the city of Athens and contains the remains of several ancient buildings of great architectural and historical significance, the most famous being the Parthenon. The word acropolis is from the Greek words ἄκρον and πόλις. The term acropolis is generic and there are many other acropoleis in Greece. During ancient times the Acropolis of Athens was known also more properly as Cecropia, after the legendary serpent-man, Cecrops, the supposed first Athenian king.

Mortar and pestle is a set of two simple tools used from the Stone Age to the present day to prepare ingredients or substances by crushing and grinding them into a fine paste or powder in the kitchen, laboratory, and pharmacy. The mortar is characteristically a bowl, typically made of hard wood, metal, ceramic, or hard stone such as granite. The pestle is a blunt, club-shaped object. The substance to be ground, which may be wet or dry, is placed in the mortar where the pestle is pounded, pressed, and rotated into the substance until the desired texture is achieved.

Menno, Baron van Coehoorn was a Dutch soldier and engineer, regarded as one of the most significant figures in Dutch military history. In an era when siege warfare dominated military campaigns, he and his French counterpart Vauban were the acknowledged experts in designing, taking and defending fortifications.

In an explosive, pyrotechnic device, or military munition, a fuse is the part of the device that initiates function. In common usage, the word fuse is used indiscriminately. However, when being specific, the term fuse describes a simple pyrotechnic initiating device, like the cord on a firecracker whereas the term fuze is used when referring to a more sophisticated ignition device incorporating mechanical and/or electronic components, such as a proximity fuze for an M107 artillery shell, magnetic or acoustic fuze on a sea mine, spring-loaded grenade fuze, pencil detonator, or anti-handling device.

A Coehorn is a lightweight mortar originally designed by Dutch military engineer Menno van Coehoorn.

A bomb vessel, bomb ship, bomb ketch, or simply bomb was a type of wooden sailing naval ship. Its primary armament was not cannons – although bomb vessels carried a few cannons for self-defence – but mortars mounted forward near the bow and elevated to a high angle, and projecting their fire in a ballistic arc. Explosive shells or carcasses were employed rather than solid shot. Bomb vessels were specialized ships designed for bombarding fixed positions on land. In the 20th century, this naval gunfire support role was carried out by the most similar purpose-built World War I- and II-era monitors, but also battleships, cruisers, and destroyers.

The Morea was the name of the Peloponnese peninsula in southern Greece during the Middle Ages and the early modern period. The name was used for the Byzantine province known as the Despotate of the Morea, by the Ottoman Empire for the Morea Eyalet, and later by the Republic of Venice for the short-lived Kingdom of the Morea.

The Stokes mortar was a British trench mortar designed by Sir Wilfred Stokes KBE that was issued to the British and U.S. armies, as well as the Portuguese Expeditionary Corps, during the latter half of the First World War. The 3-inch trench mortar is a smooth-bore, muzzle-loading weapon for high angles of fire. Although it is called a 3-inch mortar, its bore is actually 3.2 inches or 81 mm.

David Lloyd George, 1st Earl Lloyd-George of Dwyfor, was Prime Minister of the United Kingdom from 1916 to 1922. A Liberal Party statesman and politician from Wales, he was known for leading the United Kingdom during the First World War, for social-reform policies, for his role in the Paris Peace Conference, and for negotiating the establishment of the Irish Free State. He was the last Liberal Party prime minister; the party fell into third-party status shortly after the end of his premiership.

A bipod is a V-shaped portable attachment that helps support and steady a device, usually a weapon such as a long gun or a mortar. The term comes from the Latin prefix bi- and Greek root pod, meaning "two" and "foot" respectively.

A projectile is an object that is propelled by the application of an external force and then moves freely under the influence of gravity and air resistance. Although any objects in motion through space are projectiles, they are commonly found in warfare and sports.

The Brandt mle 27/31 mortar was a regulation weapon of the French army during the Second World War. Designed by Edgar Brandt, it was a refinement of the Stokes mortar. The Brandt mortar was highly influential, being licensed built or copied by numerous countries.

"Karl-Gerät" (040/041), also known as Mörser Karl, was a World War II German self-propelled siege mortar (Mörser) designed and built by Rheinmetall. Its heaviest munition was a 60 cm (24 in) diameter, 2,170 kg (4,780 lb) shell, and the range for its lightest shell of 1,250 kg (2,760 lb) was just over 10 km (6.2 mi). Each gun had to be accompanied by a crane, a two-piece heavy transport set of railcars, and several modified tanks to carry shells.

A mortar carrier, or self-propelled mortar, is a self-propelled artillery piece in which a mortar is the primary weapon. Simpler vehicles carry a standard infantry mortar while in more complex vehicles the mortar is fully integrated into the vehicle and cannot be dismounted from the vehicle. Mortar carriers cannot be fired while on the move and some must be dismounted to fire.

An insurgency is a violent, armed rebellion by small, lightly armed bands who practice guerrilla warfare from primarily rural base areas against a larger authority. The key descriptive feature of insurgency is its asymmetric nature: small irregular forces face a large, well-equipped, regular military force state adversary. Due to this asymmetry, insurgents avoid large-scale direct battles, opting instead to blend in with the civilian population where they gradually expand territorial control and military forces. Insurgency frequently hinges on control of and collaboration with local populations.

An infantry fighting vehicle (IFV), also known as a mechanized infantry combat vehicle (MICV), is a type of armoured fighting vehicle used to carry infantry into battle and provide direct-fire support. The 1990 Treaty on Conventional Armed Forces in Europe defines an infantry fighting vehicle as "an armoured combat vehicle which is designed and equipped primarily to transport a combat infantry squad, and which is armed with an integral or organic cannon of at least 20 millimeters calibre and sometimes an antitank missile launcher". IFVs often serve both as the principal weapons system and as the mode of transport for a mechanized infantry unit.

The M3 half-track was an American armored personnel carrier half-track widely used by the Allies during World War II and in the Cold War. Derived from the M2 half-track car, the M3 was extensively produced, with about 15,000 standard M3s and more than 38,000 variant units manufactured.

The M113 is a fully tracked armored personnel carrier (APC) that was developed and produced by the FMC Corporation. The M113 was sent to United States Army Europe in 1961 to replace the mechanized infantry's M59 APCs. The M113 was first used in combat in April 1962 after the United States provided the South Vietnamese Army (ARVN) with heavy weaponry such as the M113, under the Military Assistance Command, Vietnam (MACV) program. Eventually, the M113 was the most widely used armored vehicle of the U.S. Army in the Vietnam War and was used to break through heavy thickets in the midst of the jungle to attack and overrun enemy positions. It was largely known as an "APC" or an "ACAV" by the allied forces.

In guns, particularly firearms, caliber is the specified nominal internal diameter of the gun barrel bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimeters. In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a US "45 caliber" firearm has a barrel diameter of roughly 0.45 inches (11 mm). Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa.

A firing pin or striker is a part of the firing mechanism of a firearm that impacts the primer in the base of a cartridge and causes it to fire. In firearms terminology, a striker is a particular type of firing pin where a compressed spring acts directly on the firing pin to provide the impact force rather than it being struck by a hammer.

A lanyard is a cord, length of webbing, or strap that may serve any of various functions, which include a means of attachment, restraint, retrieval, and activation and deactivation. A lanyard is also a piece of rigging used to secure or lower objects aboard a ship.

Ammunition is the material fired, scattered, dropped, or detonated from any weapon or weapon system. Ammunition is both expendable weapons and the component parts of other weapons that create the effect on a target.

Infrared is electromagnetic radiation (EMR) with wavelengths longer than those of visible light and shorter than radio waves. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz). Longer IR wavelengths are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon.

The M2 4.2-inch mortar was a U.S. rifled 4.2-inch (107 mm) mortar used during the Second World War, the Korean War, and the Vietnam War. It entered service in 1943. It was nicknamed the "Goon Gun" or the "Four-Deuce". In 1951 it began to be phased out in favor of the M30 mortar of the same caliber.

The M30 106.7 mm heavy mortar is an American rifled, muzzle-loading, high-angle-of-fire weapon used for long-range indirect fire support to infantry units.

The Minié ball or Minie ball, is a type of hollow-based bullet designed by Claude-Étienne Minié, inventor of the French Minié rifle, for muzzle-loading rifled muskets. It was invented in 1847 and came to prominence in the Crimean War and the American Civil War, where it was found to inflict significantly more serious wounds than earlier round musket balls. Both the American Springfield Model 1861 and the British Pattern 1853 Enfield rifled muskets, the most common weapons used during the American Civil War, used the Minié ball.

The L16 81mm mortar is a British standard mortar used by the Canadian Army, British Army, and many other armed forces. It originated as a joint design by the UK and Canada. The version produced and used by Australia is named the F2 81mm Mortar; that used by the U.S. armed forces is known as the M252.

The M1064 mortar carrier is an American vehicle, consisting of the M121 mortar – a version of the M120 mortar – mounted on an M113 chassis. The M1287 Mortar Carrier Vehicle will replace the M1064 in U.S. Army service.

Alliant Techsystems Inc. (ATK) was an American aerospace, defense, and sporting goods company with its headquarters in Arlington County, Virginia, in the United States. The company operated in 22 states, Puerto Rico, and other countries. ATK's revenue in the 2014 fiscal year was about US$4.78 billion.

The Global Positioning System (GPS), originally Navstar GPS, is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. It does not require the user to transmit any data, and operates independently of any telephonic or Internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls and maintains the GPS system, it is freely accessible to anyone with a GPS receiver.

Artillery is a class of heavy military ranged weapons that launch munitions far beyond the range and power of infantry firearms. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery cannons developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army's total firepower.

The howitzer is an artillery weapon that falls between cannon and a mortar. With their long-range capabilities and flat trajectories, howitzers can be used to great effect in a battery formation with other artillery pieces, such as long-barreled guns, mortars, and rocket artillery.

In astrodynamics or celestial mechanics a parabolic trajectory is a Kepler orbit with the eccentricity equal to 1 and is an unbound orbit that is exactly on the border between elliptical and hyperbolic. When moving away from the source it is called an escape orbit, otherwise a capture orbit. It is also sometimes referred to as a C3 = 0 orbit (see Characteristic energy).

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.

A trench is a type of excavation or depression in the ground that is generally deeper than it is wide, and narrow compared with its length.

In military slang, a spider hole is a type of camouflaged one-man foxhole, used for observation.

Trench warfare is the type of land warfare using occupied lines largely comprising military trenches, in which troops are well-protected from the enemy's small arms fire and are substantially sheltered from artillery. Trench warfare became archetypically associated with World War I (1914–1918), when the Race to the Sea rapidly expanded trench use on the Western Front starting in September 1914.

Plunging fire is a form of indirect fire, where gunfire is fired at a trajectory to make it fall on its target from above. It is normal at the high trajectories used to attain long range, and can be used deliberately to attack a target not susceptible to direct or grazing fire due to not being in direct line of sight.

An artillery observer, artillery spotter, or forward observer (FO) is a soldier responsible for directing artillery and mortar fire support onto a target. An artillery observer usually accompanies a tank or infantry unit. Spotters ensure that indirect fire hits targets which those at a fire support base cannot see.

A Raschen bag is a bag of ballast that is placed underneath the baseplate of a mortar to improve its accuracy when used on snow or other soft ground conditions. Raschen bags are named after Colonel Dan Raschen, Royal Engineers, who invented but did not name them.

In physics and mechanics, torque is the rotational equivalent of linear force. It is also referred to as the moment of force. It represents the capability of a force to produce change in the rotational motion of the body. The concept originated with the studies by Archimedes of the usage of levers, which is reflected in his famous quote: "Give me a lever and a place to stand and I will move the Earth". Just as a linear force is a push or a pull, a torque can be thought of as a twist to an object around a specific axis. Torque is defined as the product of the magnitude of the perpendicular component of the force and the distance of the line of action of a force from the point around which it is being determined. The law of conservation of energy can also be used to understand torque. The symbol for torque is typically , the lowercase Greek letter tau. When being referred to as moment of force, it is commonly denoted by M.

The list of cannon by caliber contains all types of cannon through the ages listed in decreasing caliber size. For the purpose of this list, the development of large-calibre artillery can be divided into three periods, based on the kind of projectiles used, due to their dissimilar characteristics, and being practically incommensurable in terms of their bore size:Stone balls: Cannon of extraordinary bore, which fired stone balls, were first introduced at the turn of the 14th to 15th century in Western Europe. Following a logic of increasing performance through size, they had evolved from small handguns to giant wrought-iron or cast-bronze bombards within a span of just several decades. Iron balls and shot: By the 16th century, however, a general switch from stone balls to smaller, but much more effective iron projectiles was in full swing. This and the parallel tendency towards standardized, rapid-firing cannon made the enormously costly and logistically demanding giant guns soon obsolete in the European theatre. Explosive shells: In the Industrial Age, artillery was again revolutionized by the introduction of explosive shells, beginning with the Paixhans guns. Breakthroughs in metallurgy and modes of production were followed up by new experimentation with super-sized caliber weapons, culminating in the steel colossi of the two World Wars. In the post-war era, the development of extremely overpowered artillery was gradually abandoned in favour of missile technology, while heavy guns are still demanded by various arms of the service.

Roaring Meg was the name of several powerful cannons used in the 17th century. It is not to be confused with Mons Meg, a medieval bombard preserved at Edinburgh Castle.

The English Civil War is a generic term for a series of civil wars between Royalists and Parliamentarians in England and Wales from 1642 to 1652. Part of the wider 1639 to 1653 Wars of the Three Kingdoms, they consist of the First English Civil War, the Second English Civil War, and the Third English Civil War. The latter is now usually known as the Anglo-Scottish war (1650–1652), since most of the fighting took place in Scotland, while the Royalists consisted almost entirely of Scots Covenanters and English exiles, with no significant rising in England.

The Monster Mortar was one of the largest mortars ever developed. Also called Leopold or the Liège mortar, the 24 inches (610 mm) caliber mortar was conceived by the French artillery officer Henri-Joseph Paixhans. The mortar was manufactured under the direction of the Belgian Minister of War Baron Louis Evain and cast at the Royal Canon Foundry in Liège, Belgium in 1832. It saw action at the Battle of Antwerp in December 1832.

Henri-Joseph Paixhans was a French artillery officer of the beginning of the 19th century.

Mallet's Mortar was a British shell-firing mortar built for the Crimean War, but never used in combat.

Robert Mallet was an Irish geophysicist, civil engineer, and inventor who distinguished himself in research on earthquakes and is sometimes called the father of seismology. His son, Frederick Richard Mallet was a geologist who worked in India.

Little David was the nickname of an American 36-inch caliber mortar designed to breach the Siegfried Line and then used for test-firing aerial bombs during World War II. With the same calibre as the British Mallet's Mortar, constructed in May 1857, it is one of the largest-calibre guns ever built, having a larger calibre than both of Germany's Schwerer Gustav and Dora which were 31.5-inch (800 mm) railway guns.

The siege of Antwerp took place after fighting in the Belgian Revolution ended. On 15 November 1832, the French Armée du Nord under Marshal Gérard began to lay siege to the Dutch troops there under David Chassé. The siege ended on 23 December 1832. The French had agreed with the Belgian rebels that the latter would not participate in the battle.

"Karl-Gerät" (040/041), also known as Mörser Karl, was a World War II German self-propelled siege mortar (Mörser) designed and built by Rheinmetall. Its heaviest munition was a 60 cm (24 in) diameter, 2,170 kg (4,780 lb) shell, and the range for its lightest shell of 1,250 kg (2,760 lb) was just over 10 km (6.2 mi). Each gun had to be accompanied by a crane, a two-piece heavy transport set of railcars, and several modified tanks to carry shells.
