The Calibres de France ("French calibers") was a system of standardization of cannons in France, established by King Francis I of France from about 1525. [1] The objective was to simplify and codify cannonry, in order to facilitate production. [1] On 26 September 1526, Francis I wrote about the artillerye de mon calibre ("Artillery of my caliber"), and an even earlier mention is known from 1512. [1] The Calibres de France were formalized in an ordinance of 1552. [2]
Six standard sizes were defined: the cannon (Canon), the "grand" culverin (Grande couleuvrine), the "bastard" culverin (Couleuvrine bâtarde), the "middle" culverin (Couleuvrine moyenne), the Falconet (Faucon), and the ( Fauconneau ). [1]
The system was expanded by an ordinance dated 27 November 1572, and an edict dates December 1601. [1]
The 6-guns Calibres de France system was still in place at the time of Louis XIII, which was later developed to an 18-guns system. [3]
The system was phased out with the Keller system in 1666, and the De Vallière system on 7 October 1732. [3]
The howitzer is an artillery weapon that falls between a cannon and a mortar. It is generally aimed lower than a mortar but higher than a cannon. With their long-range capabilities, howitzers can be used to great effect in a battery formation with other artillery pieces, such as long-barreled guns, mortars, and rocket artillery.
The formal definition of large-calibre artillery used by the United Nations Register of Conventional Arms (UNROCA) is "guns, howitzers, artillery pieces, combining the characteristics of a gun, howitzer, mortar, or rocket, capable of engaging surface targets by delivering primarily indirect fire, with a calibre of 76.2 mm (3.00 in) and above". This definition, shared by the Arms Trade Treaty and the Treaty on Conventional Armed Forces in Europe, is updated from an earlier definition in United Nations General Assembly Resolution 46/36L, which set a threshold of 100 mm (3.9 in). Several grammatical changes were made to that latter in 1992 and the threshold was lowered in 2003 to yield the current definition, as endorsed by UN General Assembly Resolution 58/54.
The demi-culverin was a medium cannon similar to but slightly larger than a saker and smaller than a regular culverin developed in the late 16th century. Barrels of demi-culverins were typically about 11 feet (3.4 m) long, had a calibre of 4 inches (10 cm) and could weigh up to 3,400 pounds (1,500 kg). The gun required 6 pounds (2.7 kg) of black powder to fire an 8-pound (3.6 kg) round shot. The demi-culverin had an effective range of 1,800 feet (550 m).
A culverin was initially an ancestor of the hand-held arquebus, but the term was later used to describe a type of medieval and Renaissance cannon. The word is derived from the antiquated "culuering" and the French "couleuvrine" From its origin as a hand-held weapon it was adapted for use as artillery by the French in the 15th century and for naval use by the English in the 16th century. The culverin as an artillery piece had a long smoothbore gun barrel with a relatively long range and flat trajectory, using solid round shot projectiles with high muzzle velocity.
The falconet was a light cannon developed in the late 15th century that fired a smaller shot than the similar falcon. During the Middle Ages guns were decorated with engravings of animals, such as reptiles, birds or mythical beasts depending on their size. For example, a culverin would often feature snakes, as the handles on the early cannons were often decorated to resemble serpents. The falconet fired small yet lethal shot of similar weight and size to a bird of prey, and so was decorated with a falcon. Similarly, the musket was associated with the sparrowhawk.
The 7.5 cm KwK 42 L/70 was a 7.5 cm calibre German tank gun used on German armoured fighting vehicles in the Second World War. The gun was the armament of the Panther medium tank and two variants of the Jagdpanzer IV self-propelled anti-tank gun. On the latter it was designated as the "7.5 cm Panzerabwehrkanone 42" anti-tank gun.
The 3.7 cm Flak 18/36/37 was a series of anti-aircraft guns produced by Nazi Germany that saw widespread service in the Second World War. The cannon was fully automatic and effective against aircraft flying at altitudes up to 4,200 m. The cannon was produced in both towed and self-propelled versions. Having a flexible doctrine, the Germans used their anti-aircraft pieces in ground support roles as well; 37 mm caliber guns were no exception to that. With Germany's defeat, production ceased and, overall, 37 mm caliber anti-aircraft cannon fell into gradual disuse, being replaced by the Bofors 40 mm gun and later, by 35-mm anti-aircraft pieces produced in Switzerland.
The bombard is a type of cannon or mortar which was used throughout the Late Middle Ages and the early modern period. Bombards were mainly large calibre, muzzle-loading artillery pieces used during sieges to shoot round stone projectiles at the walls of enemy fortifications, enabling troops to break in. Most bombards were made of iron and used gunpowder to launch the projectiles. There are many examples of bombards, including Mons Meg, the Dardanelles Gun, and the handheld bombard.
Fra' Philippe de Villiers de L'Isle-Adam was a prominent member of the Knights Hospitaller at Rhodes and later Malta. Having risen to the position of Prior of the Langue of Auvergne, he was elected 44th Grand Master of the Order in 1521.
The Siege of Rhodes of 1522 was the second and ultimately successful attempt by the Ottoman Empire to expel the Knights of Rhodes from their island stronghold and thereby secure Ottoman control of the Eastern Mediterranean. The first siege in 1480 had been unsuccessful. Despite very strong defenses, the walls were demolished over the course of six months by Turkish artillery and mines.
The saker was a medium cannon, slightly smaller than a culverin, developed during the early 16th century and often used by the English. It was named after the saker falcon, a large falconry bird native to the Middle East.
The minion was a type of smoothbore cannon used during the Tudor period and into the late 17th century. It was of a smaller bore diameter - typically 3 inches (76 mm) - than larger cannons such as sakers and culverins, and usually fired round shot weighing 5 pounds (2.3 kg).
The Valée system was an artillery system developed between 1825 and 1831 by the French artillery officer Sylvain Charles Valée, and officially adopted by the French Army from 1828.
Jean-Florent de Vallière was a French artillery officer of the 18th century. He was lieutenant-general of the King's Armies. In 1726, de Vallière became Director-General of the Battalions and Schools of the Artillery.
The La Hitte system, named after the French general Ducos, Count de La Hitte, was an artillery system designed in March 1858 to implement rifled muzzle-loading guns in the French Army.
Jean-Jacques Keller (1635–1700) and his brother Jean-Balthazar Keller (1638–1702) were Swiss gunfounders from Zürich, in the service of France.
Artillery began to be used in France in the 14th century. The first depiction of a cannon in Europe appeared in Walter de Milemete's 1326 De nobilitatibus, sapientiis, et prudentiis regum. Small rudimentary weapons such as the pot-de-fer or the portable bâton à feu were introduced. At this early stage, cannon would fire either stone balls or metal pellets.
A breech-loading swivel gun was a particular type of swivel gun and a small breech-loading cannon invented in the 14th century. It was equipped with a swivel for easy rotation and was loaded by inserting a mug-shaped device called a chamber or breech block, filled with gunpowder and projectiles. It had a high rate of fire, as several chambers could be prepared in advance and quickly fired in succession and was especially effective in anti-personnel roles. It was used for centuries by many countries of Europe, Asia and Africa.
Emery d'Amboise was Grand Master of the Knights Hospitaller from 1503 to 1512. He was the 41st Grand Master. He succeeded to Pierre d'Aubusson.
The 24-pounder long gun was a heavy calibre piece of artillery mounted on warships of the Age of Sail. 24-pounders were in service in the navies of France, Spain, Great Britain, the Netherlands, Sweden, and the United States. They were comparable to the Canon de 24 Gribeauval used by the French Army as its largest piece of siege artillery. 24-pounders were used as main guns on the heaviest frigates of the early 19th century and on fourth-rate ships of the line, on the second deck of first-rate ships of the line, and on the second deck of a few large third-rates.
