Naval artillery
–
Naval artillery is artillery mounted on a warship, originally used only for naval warfare, later also for naval gunfire support against targets on land, and for anti-aircraft use. The idea of artillery dates back to the classical era. Julius Caesar indicates the use of ship-borne catapults against Britons ashore in his Commentarii de Bello Gallico, the dromons of the Byzantine Empire carried catapults and fire-throwers. From the late Middle Ages onwards, warships began to carry cannon of various calibres, the Battle of Arnemuiden, fought between England and France in 1338 at the start of the Hundred Years War, was the first recorded European naval battle using artillery. The English ship Christopher was armed with three cannons and one hand gun, by the 15th century most Mediterranean powers were utilising heavy cannon mounted on the bow or stern of a vessel and designed to bombard fortresses on shore. By mid-century some vessels also carried smaller broadside cannons for bombarding other vessels immediately prior to an attempted boarding and these small guns were anti-personnel weapons and were fired at point blank range to accompany engagement with muskets or bows. From the 1470s both the Portuguese and Venetian navies were experimenting with cannons as anti-ship weapons, in 1489 John of Portugal further contributed to the development of naval artillery by establishing the first standardized teams of trained naval gunners. The 16th century was an era of transition in naval warfare, since ancient times, war at sea had been fought much like that on land, with melee weapons and bows and arrows, but on floating wooden platforms rather than battlefields. Though the introduction of guns was a significant change, it slowly changed the dynamics of ship-to-ship combat. As guns became heavier and able to more powerful gunpowder charges, they needed to be placed lower in the ship. Although some 16th-century galleys mounted broadside cannon, they did so at the expense of rowing positions which sacrificed speed, most early cannon were still placed in the forecastle and aftercastle of a ship where they might be conveniently pointed in any direction. Early naval artillery was a weapon to deter boarders, because cannon powerful enough to damage ships were heavy enough to destabilize any ship mounting them in an elevated castle. Being a crown industry, cost considerations did not curb the pursuit of the best quality, best innovations, the crown paid wage premiums and bonuses to lure the best European artisans and gunners to advance the industry in Portugal. This made broadsides, coordinated volleys from all the guns on one side of a ship, possible for the first time in history, at least in theory. Ships, such as Mary Rose, carried a mixture of cannon of different types and sizes, many designed for land use, and using incompatible ammunition at different ranges and rates of fire. The Mary Rose, like other ships of the time, was built during a period of development of heavy artillery. The heavy armament was a mix of older-type wrought iron and cast bronze guns, the bronze guns were cast in one piece and rested on four-wheel carriages which were essentially the same as those used until the 19th century. The breech-loaders were cheaper to produce and both easier and faster to reload, but could take less powerful charges than cast bronze guns, the majority of the guns were small iron guns with short range that could be aimed and fired by a single person

Coastal artillery
–
Coastal artillery is the branch of the armed forces concerned with operating anti-ship artillery or fixed gun batteries in coastal fortifications. The advent of 20th-century technologies, especially aviation, naval aviation, jet aircraft, and guided missiles, reduced the primacy of cannon, battleships. In countries where coastal artillery has not been disbanded, these forces have acquired amphibious capabilities, in littoral warfare, mobile coastal artillery armed with surface-to-surface missiles still can be used to deny the use of sea lanes. Land-based guns also benefited in most cases from the protection of walls or earth mounds. The Martello tower is an excellent example of a widely used coastal fort which mounted defensive artillery, during the 19th century China also built hundreds of coastal fortresses in an attempt to counter Western naval threats. Coastal artillery could be part of the Navy, or part of the Army, in English-speaking countries, certain coastal artillery positions were sometimes referred to as Land Batteries, distinguishing this form of artillery battery from for example floating batteries. In the United Kingdom, in the later 19th and earlier 20th Centuries, then, following the Spanish–American War and the report of the Endicott Board, U. S. harbor defenses were greatly strengthened and provided with new, rifled artillery and minefield defenses. Shortly thereafter, in 1907, Congress split the field artillery, the first decade of the 20th Century, the United States Marine Corps established the Advanced Base Force. The force was used for setting up and defending advanced bases, during the Siege of Port Arthur, Japanese forces had captured the vantage point on 203 Meter Hill overlooking Port Arthur harbor. The battleship Sevastopol, although hit 5 times by 11-inch shells, after 3 weeks, the Sevastopol was still afloat, having survived 124 torpedoes fired at her while sinking two Japanese destroyers and damaging six other vessels. The Japanese had meanwhile lost the cruiser Takasago to a mine outside the harbor, the Blücher had entered the narrow waters of the Oslofjord, carrying 1,000 soldiers and leading a German invasion fleet. The first salvo from the Norwegian defenders, fired from Oscarsborg Fortress about 1 mile distant, disabled Blüchers main battery, fire from the smaller guns swept her decks and disabled her steering, and she received several torpedo hits before the fires reached her magazines and doomed her. Singapore was defended by its famous large-caliber coastal guns, which included one battery of three 15-inch guns and one with two 15-inch guns, AP shells were designed to penetrate the hulls of heavily armoured warships and were ineffective against personnel. The Japanese defended the island of Betio in the Tarawa atoll with numerous 203 mm coastal guns, in 1943, these were knocked out early in the battle with a combined USN naval and aerial bombardment. Nazi Germany fortified its conquered territories with the Atlantic Wall, the intent was to destroy the Allied landing craft before they could unload. During the Normandy Landings in 1944, shore bombardment was given a high importance, using ships from battleships to destroyers, for example, the Canadians at Juno beach had fire support many times greater than they had had for the Dieppe Raid in 1942. In addition, there were modified landing-craft, eight Landing Craft Gun, twenty-four Landing Craft Tank carried Priest self-propelled howitzers which also fired while they were on the run-in to the beach. Similar arrangements existed at other beaches, on June 25,1944 the American battleship Texas engaged German shore batteries on the Cotentin Peninsula

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 railway wagon. Many countries have built railway guns, but the best known are the large Krupp-built pieces used by Germany in World War I, smaller guns were often part of an armoured train. Railway guns have been rendered obsolete by advances in technology and their large size and limited mobility make them vulnerable to attack, and similar payloads can be delivered by aircraft, rocket, or missile. The design of a gun has three issues over and above those of an ordinary artillery piece to consider. The first method of traverse is to rely entirely on movement along a section of track or on a turntable with no provision to traverse the gun on its mount. The second is to traverse the rail car body on its trucks, generally this is limited to a few degrees of traverse to either side unless an elaborate foundation is built with a centre pivot and traversing rollers. The design of the foundation is the limit to the amount of traverse allowed in this latter case. The third choice is to allow the gun mount to rotate with respect to the rail car body. This usually requires the gun to be mounted on a pivot which. There are four methods to absorb the recoil force for railway guns, cradle recoil, top-carriage recoil, sliding recoil. Cradle recoil means that the gun recoils backward in its cradle and it is returned to battery, or the firing position, by either helical springs or by air in a pneumatic recuperator cylinder that is compressed by the force of recoil. This is the most common used for lighter railroad guns. Top-carriage recoil is where the gun is mounted in a carriage that moves on wheels on fixed rails. The gun and upper carriage recoil together, restrained by the hydraulic buffers. Return to battery is effected either by gravity, through the use of inclined rails and it is not well-suited to firing at high elevations because it cannot absorb much of the vertical component of the recoil force. The gun, car body and trucks all recoil together with the friction generated by the sliding on the girders absorbing the recoil force after moving only about 1 to 2 metres to the rear. The sleepers must be jacked up again to allow the gun to roll forward to its firing position and this was often done by handwheels driving gear trains attached to the wheels, or even by electric motors on more modern mounts. Almost all of type of mounts were of the non-traversing type and had to be fired from a curved section of track or turntable

World War I
–
World War I, also known as the First World War, the Great War, or the War to End All Wars, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history and it was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. The war drew in all the worlds great powers, assembled in two opposing alliances, the Allies versus the Central Powers of Germany and Austria-Hungary. These alliances were reorganised and expanded as more nations entered the war, Italy, Japan, the trigger for the war was the assassination of Archduke Franz Ferdinand of Austria, heir to the throne of Austria-Hungary, by Yugoslav nationalist Gavrilo Princip in Sarajevo on 28 June 1914. This set off a crisis when Austria-Hungary delivered an ultimatum to the Kingdom of Serbia. Within weeks, the powers were at war and the conflict soon spread around the world. On 25 July Russia began mobilisation and on 28 July, the Austro-Hungarians declared war on Serbia, Germany presented an ultimatum to Russia to demobilise, and when this was refused, declared war on Russia on 1 August. Germany then invaded neutral Belgium and Luxembourg before moving towards France, after the German march on Paris was halted, what became known as the Western Front settled into a battle of attrition, with a trench line that changed little until 1917. On the Eastern Front, the Russian army was successful against the Austro-Hungarians, in November 1914, the Ottoman Empire joined the Central Powers, opening fronts in the Caucasus, Mesopotamia and the Sinai. In 1915, Italy joined the Allies and Bulgaria joined the Central Powers, Romania joined the Allies in 1916, after a stunning German offensive along the Western Front in the spring of 1918, the Allies rallied and drove back the Germans in a series of successful offensives. By the end of the war or soon after, the German Empire, Russian Empire, Austro-Hungarian Empire, national borders were redrawn, with several independent nations restored or created, and Germanys colonies were parceled out among the victors. During the Paris Peace Conference of 1919, the Big Four imposed their terms in a series of treaties, the League of Nations was formed with the aim of preventing any repetition of such a conflict. This effort failed, and economic depression, renewed nationalism, weakened successor states, and feelings of humiliation eventually contributed to World War II. From the time of its start until the approach of World War II, at the time, it was also sometimes called the war to end war or the war to end all wars due to its then-unparalleled scale and devastation. In Canada, Macleans magazine in October 1914 wrote, Some wars name themselves, during the interwar period, the war was most often called the World War and the Great War in English-speaking countries. Will become the first world war in the sense of the word. These began in 1815, with the Holy Alliance between Prussia, Russia, and Austria, when Germany was united in 1871, Prussia became part of the new German nation. Soon after, in October 1873, German Chancellor Otto von Bismarck negotiated the League of the Three Emperors between the monarchs of Austria-Hungary, Russia and Germany

Krupp
–
The Krupp family, a prominent 400-year-old German dynasty from Essen, have become famous for their production of steel, artillery, ammunition, and other armaments. The family business, known as Friedrich Krupp AG, was the largest company in Europe at the beginning of the 20th century and it was important to weapons development and production in both world wars. One of the most powerful dynasties in European history, for 400 years Krupp flourished as the premier weapons manufacturer for Germany. From the Thirty Years War until the end of the Second World War, they produced everything from battleships, U-boats, tanks, howitzers, guns, utilities, the dynasty began in 1587 when a trader named Arndt Krupp moved to Essen and joined the merchants guild. He then began buying vacated real estate from families who fled the city due to the Black Death, over the next three centuries his descendants began producing small guns during the Thirty Years War and over time gradually acquired fulling mills, coal mines, and an iron forge. During the Napoleonic Wars, Friedrich Krupp founded the Gusstahlfabrik and began producing smelted steel in 1816, the foundations were laid for the steel Empire that would come to dominate the world for nearly a century under his son Alfred. Krupp became the manufacturer for the Kingdom of Prussia in 1859. Krupp was also a company that paved the way for workers rights. Widows and orphans were guaranteed pay if their husbands and/or fathers were killed, the company also produced the steel that built the railroads of America, capped the Chrysler Building in 1929, and was the first to travel to the bottom of the Mariana Trench. During the Third Reich, Krupp supported Adolf Hitler and the use of forced labour, after the war Krupp was rebuilt from scratch and again became one of the wealthiest companies in Europe. However a recession in 1967 caused the company severe profit loss, in 1999 the Krupp firm merged with Thyssen AG to form ThyssenKrupp AG, a large industrial conglomerate. Friedrich Krupp launched the familys metal-based activities, building a steel foundry in Essen in 1810. His son Alfred, known as the Cannon King or as Alfred the Great, invested heavily in new technology to become a significant manufacturer of steel rollers and he also invested in fluidized hotbed technologies and acquired many mines in Germany and France. Unusual for the era, he provided social services for his workers, including subsidized housing and health, the company began to make steel cannons in the 1840s—especially for the Russian, Turkish, and Prussian armies. When Alfred started with the firm, it had five employees, at his death twenty thousand people worked for Krupp—making it the worlds largest industrial company and the largest private company in the German empire. Krupps had a Great Krupp Building with an exhibition of guns at the Columbian Exposition in 1893, in the 20th century the company was headed by Gustav Krupp von Bohlen und Halbach, who assumed the surname of Krupp when he married the Krupp heiress, Bertha Krupp. After Adolf Hitler came to power in Germany in 1933, the Krupp works became the center for German rearmament. In 1943, by an order from Hitler, the company reverted to a sole-proprietorship, with Gustav

Gun barrel
–
A gun barrel is a part of firearms and artillery pieces. The hollow interior of the barrel is called the bore, a gun barrel must be able to hold in the expanding gas produced by the propellants to ensure that optimum muzzle velocity is attained by the projectile as it is being pushed out by the expanding gas. Modern small arms barrels are made of known and tested to withstand the pressures involved. Artillery pieces are made by various techniques providing reliably sufficient strength, early firearms were muzzle-loading, with powder, and then shot loaded from the muzzle, capable of only a low rate of fire. During the 19th century effective mechanical locks were invented that sealed a breech-loading weapon against the escape of propellant gases, the early Chinese, the inventors of gunpowder, used bamboo, a naturally tubular stalk, as the first barrels in gunpowder projectile weapons. Early European guns were made of iron, usually with several strengthening bands of the metal wrapped around circular wrought iron rings. The Chinese were the first to master cast-iron cannon barrels, early cannon barrels were very thick for their caliber.

Shell (projectile)
–
A shell is a payload-carrying projectile that, as opposed to shot, contains an explosive or other filling, though modern usage sometimes includes large solid projectiles properly termed shot. Solid shot may contain a pyrotechnic compound if a tracer or spotting charge is used, originally, it was called a bombshell, but shell has come to be unambiguous in a military context. Words cognate with grenade are still used for an artillery or mortar projectile in some European languages, shells are usually large-calibre projectiles fired by artillery, combat vehicles, and warships. Shells usually have the shape of a cylinder topped by a nose for good aerodynamic performance, possibly with a tapering base. Solid cannonballs did not need a fuse, but hollow munitions filled with something such as gunpowder to fragment the ball, needed a fuse, percussion fuses with a spherical projectile presented a challenge because there was no way of ensuring that the impact mechanism hit the target. Therefore, shells needed a fuse that was ignited before or during firing. The earliest record of shells being used in combat was by the Republic of Venice at Jadra in 1376, shells with fuses were used at the 1421 siege of St Boniface in Corsica. These were two hollowed hemispheres of stone or bronze held together by an iron hoop, as described in their book, these hollow, gunpowder-packed shells were made of cast iron. At least since the 16th Century grenades made of ceramics or glass were in use in Central Europe, a hoard of several hundred ceramic greandes were discovered during building works in front of a bastion of the Bavarian City of Ingolstadt, Germany dated to the 17th Century. Lots of the grenades obtained their orignal blackpowder loads and igniters, most probably the grenades were intentionally dumped the moat of the bastion before the year 1723. Early powder burning fuses had to be loaded fuse down to be ignited by firing or a portfire put down the barrel to light the fuse, other shells were wrapped in bitumen cloth, which would ignite during the firing and in turn ignite a powder fuse. Nevertheless, shells came into use in the 16th Century. By the 18th Century, it was known that the fuse towards the muzzle could be lit by the flash through the windage between the shell and the barrel, the use of exploding shells from field artillery became relatively commonplace from early in the 19th century. Until the mid 19th century, shells remained as simple exploding spheres that used gunpowder and they were usually made of cast iron, but bronze, lead, brass and even glass shell casings were experimented with. The word bomb encompassed them at the time, as heard in the lyrics of The Star-Spangled Banner, typically, the thickness of the metal body was about a sixth of their diameter and they were about two thirds the weight of solid shot of the same calibre. To ensure that shells were loaded with their fuses towards the muzzle, in 1819, a committee of British artillery officers recognised that they were essential stores and in 1830 Britain standardised sabot thickness as a half inch. The sabot was also intended to reduce jamming during loading, despite the use of exploding shell, the use of smoothbore cannons, firing spherical projectiles of shot, remained the dominant artillery method until the 1850s. By the late 18th century, artillery could use canister shot to defend itself from infantry or cavalry attack and this involved loading a tin or canvas container filled with small iron or lead balls instead of the usual cannonball

Breech-loading weapon
–
A breech-loading gun is a firearm in which the cartridge or shell is inserted or loaded into a chamber integral to the rear portion of a barrel. Modern mass production firearms are breech-loading, early firearms, on the other hand, were almost entirely muzzle-loading. In field artillery, breech loading allows the crew to reload the gun without exposing themselves to fire or repositioning the piece. The main challenge for developers of breech-loading firearms was sealing the breech and this was eventually solved for smaller firearms by the development of the self-contained metallic cartridge. For firearms too large to use cartridges, the problem was solved by the development of the interrupted screw, breech-loading swivel guns were invented in the 14th century. The breech-loading swivel gun had a rate of fire, and was especially effective in anti-personnel roles. Breech-loading firearms are known from the 16th century, Henry VIII possessed one, which he apparently used as a hunting gun to shoot birds. More breech-loading firearms were made in the early 18th century, one such gun known to have belonged to Philip V of Spain, and was manufactured circa 1715, probably in Madrid. It came with a ready-to load reusable cartridge, patrick Ferguson, a British Army officer, developed in 1772 the Ferguson rifle, a breech-loading flintlock firearm. Later on into the century there were attempts in Europe at an effective breech-loader. There were concentrated attempts at improved cartridges and methods of ignition, the cartridge was loaded through the breech and fired with a needle. The needle-activated central-fire breech-loading gun would become a feature of firearms thereafter. The corresponding firearm was also developed by Pauly, Pauly made an improved version, which was protected by a patent on 29 September 1812. In 1846 another Paris Frenchman, Benjamin Houllier, patented the first fully metallic cartridge containing powder in a metallic shell, Houllier commercialised his weapons in association with the gunsmiths Blanchard or Charles Robert. In English-speaking countries the Flobert cartridge corresponds to the.22 BB, the first centrefire cartridge was introduced in 1855 by Pottet, with both Berdan and Boxer priming. The Dreyse Zündnadelgewehr or Dreyse needle gun, was a single-shot breech-loading rifle using a rotating bolt to seal the breech and it was so called because of its. 5-inch needle-like firing pin, which passed through a paper cartridge case to impact a percussion cap at the bullet base. It began development in the 1830s under von Dreyse and eventually a version of it was adopted by Prussia in the late 1840s. The paper cartridge and the gun had numerous deficiencies, specifically, however, the rifle was used to great success in the Prussian army in the Austro-Prussian war of 1866

Rifled breech loader
–
The spin imparted by the guns rifling gives projectiles directional stability and increased range. Loading from the rear of the gun leaves the crew exposed to enemy fire, allows smaller gun emplacements or turrets. This was both a safety issue and one of gun performance - all the propellant gas was needed to accelerate the projectile along the barrel. The second problem was speed of operation - how to close the breech before firing, two solutions were developed more or less in parallel, the screw breech block and sliding wedge or sliding block. Hence, unlike with a rifle cartridge, the breech mechanism itself somehow needed to provide obturation. Hence if the block circumference was divided into two sets of threads and gaps, the only needed to be rotated ¼ turn to lock it instead of several turns. The tradeoff was that only ½ the blocks circumference was threaded, until the 19th century, only muzzle-loaders were used. In 1837 Martin von Wahrendorff patented a design for a breech-loader with a cylindrical breech plug secured by a horizontal wedge, independently, Giovanni Cavalli first proposed a breech-loader gun in 1832 to the Sardinian Army, and first tested such a gun in 1845. Advances in metallurgy in the industrial era allowed for the construction of rifled breech-loading guns that could fire at a greater muzzle velocity. Production started in 1855 at the Elswick Ordnance Company and the Royal Arsenal at Woolwich, a degree of obturation was achieved via a cup on the face of the block being forced into a recessed ring on the chamber face. Whatever obturation that was achieved relied on manual labour rather than the power of the guns firing, however, the British Army and Navy preferred to revert to muzzle-loaders until larger high-powered breech-loaders with secure obturation systems that were relatively simple to operate were developed. In the meantime the French persevered with trying to develop breechloaders which combined faster loading than muzzle-loaders, high power, safety, the Lahitolle 95 mm cannon of 1875 with an interrupted screw breech met the first three requirements to a great extent and partially solved the obturation problem. Finally the de Bange system introduced in 1877 solved the problem with an asbestos pad impregnated with grease which expanded and sealed the breech on firing. The de Bange system formed the system for all subsequent screw breeches to the present day. Britain adopted the de Bange breech when it returned to breechloaders in the early 1880s after some experiments with the inferior Armstrong cup obturation system. Loading required the 3 operations in reverse and this was hence termed a three motion block and was slow to operate. While working as a designer for Thorsten Nordenfelt in London. This allowed the block to be unscrewed and swung out in two motions - the two motion interrupted screw breech, bofors continued to use this in medium artillery into the 20th century

Bundeswehr
–
The Bundeswehr is the unified armed forces of Germany and their civil administration and procurement authorities. The States of Germany are not allowed to maintain armed forces of their own, the Bundeswehr is divided into a military part and a civil part with the armed forces administration. The military part of the defense force consists of the Heer, Marine, Luftwaffe, Streitkräftebasis, Zentraler Sanitätsdienst. In addition the Bundeswehr has approximately 27,600 reserve personnel. 2%, the Bundeswehr are in the process of integrating smaller NATO members Brigades into divisions of the German army. The Bundeswehr is to play a role as anchor army for smaller NATO states. 2 of 3 Royal Netherlands Army Brigades are now under German Command, in 2014 the 11th Airmobile Brigade, was integrated into the German Division of fast forces. Also the Dutch 43rd Mechanized Brigade, will be integrated into the 1st Panzer Division of the German army, with the integration starting at the beginning of 2016, and the unit becoming operational at the end of 2019. The Dutch-German military cooperation are seen as an example for setting up a European defense union, also the Czech Republics 4th Rapid Deployment Brigade, and Romania’s 81st Mechanized Brigade, will be integrated into Germany’s 10 Armoured Division and Rapid Response Forces Division. The name Bundeswehr was first proposed by the former Wehrmacht general and Liberal politician Hasso von Manteuffel, the Iron Cross is its official emblem. It is a symbol that has an association with the military of Germany. The Schwarzes Kreuz is derived from the black cross insignia of the medieval Teutonic knights, when the Bundeswehr was established in 1955, its founding principles were based on developing a completely new military force for the defence of West Germany. In this respect the Bundeswehr did not consider itself to be a successor to either the Reichswehr of the Weimar Republic or Hitlers Wehrmacht, neither does it adhere to the traditions of any former German military organization. One of the most visible traditions of the modern Bundeswehr is the Großer Zapfenstreich, the FRG reinstated this formal military ceremony in 1952, three years before the foundation of the Bundeswehr. Today it is performed by a band with 4 fanfare trumpeters and timpani. The Zapfenstreich is only performed during national celebrations or solemn public commemorations and it can honour distinguished persons present such as the German federal president or provide the conclusion to large military exercises. Another important tradition in the modern German armed forces is the Gelöbnis, there are two kinds of oath, for conscripts/recruits it is a pledge but its a solemn vow for full-time personnel. The pledge is made annually on 20 July, the date on which a group of Wehrmacht officers attempted to assassinate Adolf Hitler in 1944, recruits from the Bundeswehrs Wachbataillon make their vow at the Bendlerblock in Berlin. This was the headquarters of the resistance but also where the officers were executed following its failure
