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

Russian Civil War
–
The Russian Civil War was a multi-party war in the former Russian Empire immediately after the Russian Revolutions of 1917, as many factions vied to determine Russias political future. In addition, rival militant socialists and nonideological Green armies fought against both the Bolsheviks and the Whites, eight foreign nations intervened against the Red Army, notably the Allied Forces and the pro-German armies. The Red Army defeated the White Armed Forces of South Russia in Ukraine, the remains of the White forces commanded by Pyotr Nikolayevich Wrangel were beaten in Crimea and evacuated in late 1920. Lesser battles of the war continued on the periphery for two years, and minor skirmishes with the remnants of the White forces in the Far East continued well into 1923. Armed national resistance in Central Asia was not completely crushed until 1934, there were an estimated 7,000, 000–12,000,000 casualties during the war, mostly civilians. The Russian Civil War has been described by some as the greatest national catastrophe that Europe had yet seen, many pro-independence movements emerged after the break-up of the Russian Empire and fought in the war. Several parts of the former Russian Empire—Finland, Estonia, Latvia, Lithuania, the rest of the former Russian Empire was consolidated into the Soviet Union shortly afterwards. After the abdication of Tsar Nicholas II of Russia, the Russian Provisional Government was established during the February Revolution of 1917, Political commissars were appointed to each unit of the army to maintain morale and ensure loyalty. In June 1918, when it became apparent that an army composed solely of workers would be far too small. Former Tsarist officers were utilized as military specialists, sometimes their families were taken hostage in order to ensure their loyalty, at the start of the war three-quarters of the Red Army officer corps was composed of former Tsarist officers. By its end, 83% of all Red Army divisional and corps commanders were ex-Tsarist soldiers, a Ukrainian nationalist movement was active in Ukraine during the war. More significant was the emergence of an anarchist political and military movement known as the Revolutionary Insurrectionary Army of Ukraine or the Anarchist Black Army led by Nestor Makhno, some of the military forces were set up on the basis of clandestine officers organizations in the cities. The Czechoslovak Legions had been part of the Russian army and numbered around 30,000 troops by October 1917 and they had an agreement with the new Bolshevik government to be evacuated from the Eastern Front via the port of Vladivostok to France. The transport from the Eastern Front to Vladivostok slowed down in the chaos, under pressure from the Central Powers, Trotsky ordered the disarming and arrest of the legionaries, which created tensions with the Bolsheviks. The Western Allies armed and supported opponents of the Bolsheviks, hence, many of these countries expressed their support for the Whites, including the provision of troops and supplies. Winston Churchill declared that Bolshevism must be strangled in its cradle, the British and French had supported Russia during World War I on a massive scale with war materials. After the treaty, it looked like much of material would fall into the hands of the Germans. Under this pretext began allied intervention in the Russian Civil War with the United Kingdom, there were violent clashes with troops loyal to the Bolsheviks

Winter War
–
The Winter War was a military conflict between the Soviet Union and Finland in 1939–1940. It began with the Soviet invasion of Finland on 30 November 1939, the League of Nations deemed the attack illegal and expelled the Soviet Union from the League on 14 December 1939. Finland refused and the USSR invaded the country, the Soviets possessed more than three times as many soldiers as the Finns, thirty times as many aircraft, and a hundred times as many tanks. The Red Army, however, had been crippled by Soviet leader Joseph Stalins Great Purge of 1937. With more than 30,000 of its officers executed or imprisoned, including most of those of the highest ranks, because of these factors, and high morale in the Finnish forces, Finland repelled Soviet attacks for several months, much longer than the Soviets expected. However, after reorganization and adoption of different tactics, the renewed Soviet offensive overcame Finnish defenses at the borders, hostilities ceased in March 1940 with the signing of the Moscow Peace Treaty. Finland ceded territory representing 11% of its area and 13% of its economy to the Soviet Union. Soviet losses were heavy, and the international reputation suffered. While the Soviet Union did not conquer all Finland, Soviet gains exceeded their pre-war demands and they gained substantial territory along Lake Ladoga, providing a buffer for Leningrad, and territory in northern Finland. Finland retained its sovereignty and enhanced its international reputation, the end of the war cancelled the Franco-British plan to send troops to Finland through northern Scandinavia. One of the goals of the projected Franco-British operation had been to take control of northern Swedens iron ore. For this reason it was also a factor in the launching of Operation Weserübung, Nazi Germanys invasion of Denmark. The poor performance of the Red Army encouraged Hitler to think that an attack on the Soviet Union would be successful, until the beginning of the 19th century, Finland constituted the eastern part of the Kingdom of Sweden. In 1809, to protect their capital, Saint Petersburg. While abortive because of Russias internal strife, these attempts ruined Russias relations with the Finns, the new Bolshevik Russian government was weak, and with the threat of civil war looming Soviet Russia recognized the new Finnish government just three weeks after the declaration of independence. Sovereignty was fully achieved in May 1918 after a civil war. Finland joined the League of Nations in 1920, from which it sought security guarantees, nevertheless, the government of Sweden carefully avoided committing itself to Finnish foreign policy. Another Finnish military policy was the top secret military cooperation between Finland and Estonia, the 1920s and early 1930s were a politically unstable time in Finland

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

Vickers
–
Vickers was a famous name in British engineering that existed through many companies from 1828 until 1999. Vickers was formed in Sheffield as a foundry by the miller Edward Vickers. Naylor was a partner in the foundry Naylor & Sanderson and Vickers brother William owned a steel rolling operation, edwards investments in the railway industry allowed him to gain control of the company, based at Millsands and known as Naylor Vickers and Company. It began life making steel castings and quickly became famous for casting church bells and its great architects, the historian Clive Trebilcock writes, Colonel T. E. and Albert Vickers. Both men were autocrats by temperament, but neither shunned advice or avoided delegation, each, in 1863 the company moved to a new site in Sheffield on the River Don in Brightside. The company went public in 1867 as Vickers, Sons & Company and gradually acquired more businesses, in 1868 Vickers began to manufacture marine shafts, in 1872 they began casting marine propellers and in 1882 they set up a forging press. Vickers produced their first armour plate in 1888 and their first artillery piece in 1890, Vickers bought out the Barrow-in-Furness shipbuilder The Barrow Shipbuilding Company in 1897, acquiring its subsidiary the Maxim Nordenfelt Guns and Ammunition Company. At the same time, to become Vickers, Sons & Maxim, Ordnance and ammunition made during this period, including World War I, was stamped V. S. M. The yard at Barrow became the Naval Construction Yard, with these acquisitions, Vickers could now produce a complete selection of products, from ships and marine fittings to armour plate and a whole suite of ordnance. In 1901 the Royal Navys first submarine, Holland 1, was launched at the Naval Construction Yard, in 1902 Vickers took a half share in the famous Clyde shipyard John Brown and Company. In 1911 a controlling interest was acquired in Whitehead and Company, in 1919, the British Westinghouse electrical company was taken over as the Metropolitan Vickers Electrical Company, Metrovick. At the same time came into Metropolitans railway interests. In 1927, Vickers merged with the Tyneside based engineering company Armstrong Whitworth, founded by W. G. Armstrong, to become Vickers-Armstrongs, armstrongs shipbuilding interests became the Naval Yard, those of Vickers on the west coast the Naval Construction Yard. Armstrong Whitworth Aircraft was not absorbed by the new company, in 1928 the Aviation Department became Vickers Ltd and soon after acquired Supermarine, which became the Supermarine Aviation Works Ltd. In 1938, both companies were re-organised as Vickers-Armstrongs Ltd, although the former Supermarine and Vickers works continued to brand their products under their former names. 1929 saw the merger of the railway business with those of Cammell Laird to form Metropolitan Cammell Carriage and Wagon. In 1960 the aircraft interests were merged with those of the Bristol, English Electric Company and this was owned by Vickers, English Electric and Bristol. BAC in turn owned 70% of Hunting, the Supermarine operation was closed in 1963 and the Vickers name for aircraft was dropped in 1965

Obukhov State Plant
–
Obukhov State Plant is a major Russian metallurgy and heavy machine-building plant in St. Petersburg, Russia. It was founded in 1863 to produce naval artillery based on German designs by Krupp and it has since been a major producer of artillery and other military equipment. V. Volodarsky was assassinated when making his way to a meeting relating to industrial unrest in the factory, from 1922 to 1992 it was renamed Bolshevik Plant no.232. In the late 1920s, it one of the two main Soviet tank factories, and produced the first indigenous tank, the T-18. It later became home to the AVO-5 tank design bureau, soon renamed OKMO, in 1932, the tank department of the Bolshevik factory, became the new Factory No.174. This new, independent enterprise was dedicated to the production of T-26, janusz Magnuski says that in 1935 one of the former departments of the Bolshevik factory became a base for the new independent Factory No.185. The OKMO, for a few months a part of Factory No,174, moved at the same time to Factory No.185. The new enterprise was dedicated to the production of tanks. The main part of Bolshevik Factory remained focused on production of heavy artillery, on the other hand, Zaloga says that in 1935, after the assassination of Sergey Kirov, the whole Bolshevik Factory No.232 was renamed Factory No. 185, yet Leningrad inhabitants continued to refer to it as the Bolshevik Factory, the Leningrad factorys historical name was restored in 1992 by the formation of a unitary enterprise, FSUE Obukhov State Plant. In 2002 it became part of the Almaz-Antey military industrial concern, official webpage of the OJSC GOZ Obukhov Plant Description of 305 mm naval guns manufactured by Obukhov

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.
