The Artillery Museum of Finland
–
The Artillery Museum of Finland is a special military museum dedicated to the history of the artillery from the 15th century to the present day. It was located in Niinisalo from 1977 to 1997, in 1997 it was relocated to Hämeenlinna. A museum dedicated to the artillery was discussed in Finland already in the 1930s. The idea was revived again in the beginning of the 1970s, a possibility of establishing the museum seemed feasible but the location was problematic. Proximity of some large artillery garrison was considered best for the museum, in the heart of Satakunta, in Niinisalo, a suitable building was found. An empty school of Saloharju was rented to Tykkimiehet Association by the borough of Kankaanpää, the large artillery garrison of Niinisalo was placed quite near. The museum was founded on 2 July 1977 in Niinisalo under the name Artillery Museum, the great public did not, however, quite find its way to the museum, probably because of its remoteness. A campaign for finding a new location was launched, Linnankasarmi at Hämeenlinna, with its vacant barracks, begun to feel attractive. The new Artillery Museum was opened to the public on 12 May 1997, the name of the museum was changed 1.1.2004 to The Artillery Museum of Finland. The Artillery Museum of Finland is located at Hämeenlinna in the Linnakasarmi area, the buildings of Linnankasarmi date back to the Russian regime, to the Autonomy 1809–1917. The construction of the started in 1850 and was completed in 1913. Moreover, Häme Castle is right next door and its centurys long tradition includes also artillery, the permanent exhibition displays in three floors the history of artillery in Finland and the military history on the nation. On the ground floor of the building the birth of our artillery centuries ago is on display. The story proceeds from the War of Finland 1808-1809 through the period of Autonomy to the Finnish Civil War, a muzzleloader called Helvig, a cannon dating back to the War of Finland 1808-1809 is one of the guns worth mentioning. On the center passage of each there are projectiles from different periods. The second floor brings the visitor to the times of the winter, the firing methods of the field artillery and of the subjects connected, demonstrate the high technical know-how of the Finnish artillery. The study of the Artillery General Vilho Nenonen is also in this floor, the proto type of the Nenon – camera is on display in this room. The floor of the artillery veterans ends with the present time, special branches, such as artillery intelligence, communications and survey activities are placed on this floor

Kingdom of Italy
–
The state was founded as a result of the unification of Italy under the influence of the Kingdom of Sardinia, which can be considered its legal predecessor state. Italy declared war on Austria in alliance with Prussia in 1866, Italian troops entered Rome in 1870, ending more than one thousand years of Papal temporal power. Italy entered into a Triple Alliance with Germany and Austria-Hungary in 1882, victory in the war gave Italy a permanent seat in the Council of the League of Nations. Fascist Italy is the era of National Fascist Party rule from 1922 to 1943 with Benito Mussolini as head of government, according to Payne, Fascist regime passed through several relatively distinct phases. The first phase was nominally a continuation of the parliamentary system, then came the second phase, the construction of the Fascist dictatorship proper from 1925 to 1929. The third phase, with activism, was 1929–34. The war itself was the phase with its disasters and defeats. Italy was allied with Nazi Germany in World War II until 1943 and it switched sides to the Allies after ousting Mussolini and shutting down the Fascist party in areas controlled by the Allied invaders. Shortly after the war, civil discontent led to the referendum of 1946 on whether Italy would remain a monarchy or become a republic. Italians decided to abandon the monarchy and form the Italian Republic, the Kingdom of Italy claimed all of the territory which is modern-day Italy. The development of the Kingdoms territory progressed under Italian re-unification until 1870, the state for a long period of time did not include Trieste or Trentino-Alto Adige/Südtirol, which are in Italy today, and only annexed them in 1919. After the Second World War, the borders of present-day Italy were founded, the Kingdom of Italy was theoretically a constitutional monarchy. Executive power belonged to the monarch, as executed through appointed ministers, two chambers of parliament restricted the monarchs power—an appointive Senate and an elective Chamber of Deputies. The kingdoms constitution was the Statuto Albertino, the governing document of the Kingdom of Sardinia. In theory, ministers were responsible to the king. However, in practice, it was impossible for an Italian government to stay in office without the support of Parliament, members of the Chamber of Deputies were elected by plurality voting system elections in uninominal districts. A candidate needed the support of 50% of those voting, and of 25% of all enrolled voters, if not all seats were filled on the first ballot, a runoff was held shortly afterwards for the remaining vacancies. After a brief multinominal experimentation in 1882, proportional representation into large, regional, Socialists became the major party, but they were unable to form a government in a parliament split into three different factions, with Christian Populists and classical liberals

World War II
–
World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945, although related conflicts began earlier. It involved the vast majority of the worlds countries—including all of the great powers—eventually forming two opposing alliances, the Allies and the Axis. It was the most widespread war in history, and directly involved more than 100 million people from over 30 countries. Marked by mass deaths of civilians, including the Holocaust and the bombing of industrial and population centres. These made World War II the deadliest conflict in human history, from late 1939 to early 1941, in a series of campaigns and treaties, Germany conquered or controlled much of continental Europe, and formed the Axis alliance with Italy and Japan. Under the Molotov–Ribbentrop Pact of August 1939, Germany and the Soviet Union partitioned and annexed territories of their European neighbours, Poland, Finland, Romania and the Baltic states. In December 1941, Japan attacked the United States and European colonies in the Pacific Ocean, and quickly conquered much of the Western Pacific. The Axis advance halted in 1942 when Japan lost the critical Battle of Midway, near Hawaii, in 1944, the Western Allies invaded German-occupied France, while the Soviet Union regained all of its territorial losses and invaded Germany and its allies. During 1944 and 1945 the Japanese suffered major reverses in mainland Asia in South Central China and Burma, while the Allies crippled the Japanese Navy, thus ended the war in Asia, cementing the total victory of the Allies. World War II altered the political alignment and social structure of the world, the United Nations was established to foster international co-operation and prevent future conflicts. The victorious great powers—the United States, the Soviet Union, China, the United Kingdom, the Soviet Union and the United States emerged as rival superpowers, setting the stage for the Cold War, which lasted for the next 46 years. Meanwhile, the influence of European great powers waned, while the decolonisation of Asia, most countries whose industries had been damaged moved towards economic recovery. Political integration, especially in Europe, emerged as an effort to end pre-war enmities, the start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland, Britain and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931. Others follow the British historian A. J. P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously and this article uses the conventional dating. Other starting dates sometimes used for World War II include the Italian invasion of Abyssinia on 3 October 1935. The British historian Antony Beevor views the beginning of World War II as the Battles of Khalkhin Gol fought between Japan and the forces of Mongolia and the Soviet Union from May to September 1939, the exact date of the wars end is also not universally agreed upon. It was generally accepted at the time that the war ended with the armistice of 14 August 1945, rather than the formal surrender of Japan

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

Explosive material
–
An explosive charge is a measured quantity of explosive material, which may be composed of a single ingredient or a combination of two or more. Materials that detonate are said to be high explosives and materials that deflagrate are said to be low explosives, Explosives may also be categorized by their sensitivity. Sensitive materials that can be initiated by a small amount of heat or pressure are primary explosives. A wide variety of chemicals can explode, a number are manufactured specifically for the purpose of being used as explosives. The remainder are too dangerous, sensitive, toxic, expensive, unstable, in contrast, some materials are merely combustible or flammable if they burn without exploding. The distinction, however, is not razor-sharp, though early thermal weapons, such as Greek fire, have existed since ancient times, the first widely used explosive in warfare and mining was black powder, invented in 9th century China. This material was sensitive to water, and it produced copious amounts of dark smoke, the first useful explosive stronger than black powder was nitroglycerin, developed in 1847. Since nitroglycerin is a liquid and highly unstable, it was replaced by nitrocellulose, TNT in 1863, smokeless powder, dynamite in 1867, World War I saw the adoption of TNT trinitrotoluene in artillery shells. World War II saw a use of new explosives. In turn, these have largely replaced by more powerful explosives such as C-4. However, C-4 and PETN react with metal and catch fire easily, yet unlike TNT, C-4 and PETN are waterproof, the largest commercial application of explosives is mining. In Materials Science and Engineering, explosives are used in cladding, a thin plate of some material is placed atop a thick layer of a different material, both layers typically of metal. Atop the thin layer is placed an explosive, at one end of the layer of explosive, the explosion is initiated. The two metallic layers are forced together at high speed and with great force, the explosion spreads from the initiation site throughout the explosive. Ideally, this produces a metallurgical bond between the two layers and it is possible that some fraction of the surface material from either layer eventually gets ejected when the end of material is reached. Hence, the mass of the now welded bilayer, may be less than the sum of the masses of the two initial layers, there are applications where a shock wave, and electrostatics, can result in high velocity projectiles. Thus, explosives are substances that contain an amount of energy stored in chemical bonds. Consequently, most commercial explosives are compounds containing -NO2, -ONO2 and -NHNO2 groups that

High-explosive anti-tank warhead
–
High-explosive anti-tank warhead is a type of shaped charge explosive that uses the Munroe effect to penetrate armor. The warhead functions by having the explosive charge melt a metal liner to form a high-velocity superplastic jet and this concentrated metal jet is capable of penetrating armor steel to a depth of seven or more times the diameter of the charge. Contrary to a misconception, the jet does not melt its way through armor. The HEAT warhead has become less effective against tanks and other armored vehicles due to the use of composite armour, HEAT warheads were developed during World War II, from extensive research and development into shaped charge warheads. Shaped charge warheads were promoted internationally by the Swiss inventor Henry Mohaupt, before 1939, Mohaupt demonstrated his invention to British and French ordnance authorities. Claims for priority of invention are difficult to due to subsequent historic interpretations, secrecy, espionage. This has some claim to have been the first HEAT warhead, the design of the warhead was simple and was capable of penetrating 52 millimetres of armour. The fuze of the grenade was armed by removing a pin in the tail which prevented the firing pin from flying forward. Simple fins gave it stability in the air and, provided the hit the target at the proper angle of 90 degrees. Detonation occurred on impact, when a striker in the tail of the grenade overcame the resistance of a spring and was thrown forward into a stab detonator. By mid-1940, Germany introduced the first HEAT round to be fired by a gun, the 7.5 centimetres fired by the Kw. K.37 L/24 of the Panzer IV tank and the Stug III self-propelled gun. The Panzerfaust and Panzerschreck gave the German infantryman the ability to any tank on the battlefield from 50–150 metres with relative ease of use. The Germans made use of quantities of HEAT ammunition in converted 7.5 cm Pak 97/38 guns from 1942. These so-called Schwere Hohlladung warheads were intended for use against heavily armoured battleships, operational versions weighed nearly two tons and were perhaps the largest HEAT warheads ever deployed. A five-ton version code-named Beethoven was also developed, meanwhile, the British No.68 AT rifle grenade was proving to be too light to deal significant damage, resulting in it rarely being used in action. Due to these limits, a new infantry weapon was needed. By 1942, the PIAT had been developed by Major Millis Jefferis and it was a combination of a HEAT warhead with a spigot mortar delivery system. While cumbersome, the weapon allowed British infantry to armour at range for the first time

Shrapnel shell
–
They relied almost entirely on the shells velocity for their lethality. The munition has been obsolete since the end of World War I for anti-personnel use, the functioning and principles behind Shrapnel shells are fundamentally different from high-explosive shell fragmentation. In 1784, Lieutenant Shrapnel of the Royal Artillery began developing an anti-personnel weapon, when fired, the container burst open during passage through the bore or at the muzzle, giving the effect of an oversized shotgun shell. At ranges of up to 300 m canister shot was still highly lethal, though at this range the shots’ density was much lower and his shell was a hollow cast-iron sphere filled with a mixture of balls and powder, with a crude time fuze. If the fuze was set correctly then the shell would break open, either in front or above the intended target, the shrapnel balls would carry on with the remaining velocity of the shell. The explosive charge in the shell was to be just enough to break the casing rather than scatter the shot in all directions, as such his invention increased the effective range of canister shot from 300 to about 1100 m. He called his device spherical case shot, but in time it came to be called after him, Various solutions were tried, with limited if any success. However, in 1852 Colonel Boxer proposed using a diaphragm to separate the bullets from the bursting charge, as a buffer to prevent lead shot deforming, a resin was used as a packing material between the shot. A useful side effect of using the resin was that the combustion also gave a visual reference upon the shell bursting and it took until 1803 for the British artillery to adopt the shrapnel shell, albeit with great enthusiasm when it did. Henry Shrapnel was promoted to major in the same year, the first recorded use of shrapnel by the British was in 1804 against the Dutch at Fort Nieuw-Amsterdam in Surinam. The Duke of Wellingtons armies used it from 1808 in the Peninsular War and at the Battle of Waterloo, the design was improved by Captain E. M. Boxer of the Royal Arsenal around 1852 and crossed over when cylindrical shells for rifled guns were introduced. The powder charge both shattered the cast iron wall and liberated the bullets. The broken shell wall continued mainly forward but had little destructive effect, in the 1870s William Armstrong provided a design with the bursting charge in the head and the shell wall made of steel and hence much thinner than previous cast-iron shrapnel shell walls. Britain adopted this solution for several smaller calibres but by World War I few if any such shells remained, the final shrapnel shell design, adopted in the 1880s, bore little similarity to Henry Shrapnels original design other than its spherical bullets and time fuze. It used a much thinner forged steel shell case with a fuze in the nose. The use of steel allowed the wall to be made much thinner. It also withstood the force of the charge without shattering, so that the bullets were fired forward out of the shell case with increased velocity. This is the design came to be adopted by all countries and was in standard use when World War I began in 1914
