Soviet cruiser Krasnyi Kavkaz
–
Krasnyi Kavkaz was a cruiser of the Soviet Navy that began construction during World War I, but was still incomplete during the Russian Revolution. Her design was modified by the Soviets and she was completed in 1932. During World War II she supported Soviet troops during the Siege of Odessa, Siege of Sevastopol, and she was awarded the Guards title on 3 April 1942. She was reclassified as a ship in May 1947 before being expended as a target in 1952. Laid down on 18 October 1913 at the Rossud Dockyard as Admiral Lazarev for the Imperial Russian Navy as a cruiser of the Svetlana class, construction was abandoned in 1917 during the October Revolution when the ship was 63% complete. In the second half of 1918, the Marine Department of Hetman Pavlo Skoropadskyi was engaged in completion of ship, on 25 January 1919, the ship was formally renamed in Hetman Petro Doroshenko, but Mykolaiv was captured shortly afterward by the Entente. The hull was undamaged and the Soviets decided to finish the ship to a modified design. She was renamed Krasnyi Kavkaz on 14 December 1926, and completed to a modernized design, Krasnyi Kavkaz was initially intended to accommodate eight 8-inch guns in four twin turrets, but this was impossible given her small and lightly constructed hull. Three twin turrets mounting the new 57-caliber 180 mm B-1-K gun under development also proved impracticable and her superstructure was massively revised to fit these turrets and all of the original casemated 130-millimeter /55 B7 Pattern 1913 guns were removed. As completed her secondary armament was only four 30-caliber 76.2 mm Lender AA guns mounted between her funnels and her original internal torpedo tubes were replaced by four triple 533-millimetre torpedo mounts mounted on each side of the main deck abaft the forecastle break. She was given an aircraft-handling crane, but a catapult wasnt installed aft of her rear funnel until 1935 when a Heinkel catapult was imported from Germany and she was also fitted for mine rails with a capacity of up to 120 mines. The light cruiser Komintern collided with her in May 1932, shortly after her commissioning and it was extensively rebuilt and increased her overall length by over 11 metres. In 1933 she made visits in Turkey, Greece and Italy. She was refitted before Operation Barbarossa, probably about 1940, her catapult was removed, Two single mounts for 76.2 mm 34-K guns were also fitted, one on each side of the quarterdeck just aft of the rearmost main gun turret. Some of these guns may have been received earlier, the sources are unclear, while under repair at Poti in late 1942 she landed her aft pair of torpedo tubes and received two more Minizini mounts salvaged from the sunken cruiser Chervona Ukraina. Ten single mounts for the version of the 37 mm AA gun was also fitted. By 1944 she was carrying one quadruple Vickers.50 machine gun MK III mount on top of each of her superfiring main gun turrets. Krasnyi Kavkaz, in company with the cruisers Chervona Ukraina, Komintern and she provided gunfire support to Soviet forces defending Odessa and escorted convoys bringing the 157th Rifle Division into Odessa during the month of September 1941

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

Soviet Union
–
The Soviet Union, officially the Union of Soviet Socialist Republics was a socialist state in Eurasia that existed from 1922 to 1991. It was nominally a union of national republics, but its government. The Soviet Union had its roots in the October Revolution of 1917 and this established the Russian Socialist Federative Soviet Republic and started the Russian Civil War between the revolutionary Reds and the counter-revolutionary Whites. In 1922, the communists were victorious, forming the Soviet Union with the unification of the Russian, Transcaucasian, Ukrainian, following Lenins death in 1924, a collective leadership and a brief power struggle, Joseph Stalin came to power in the mid-1920s. Stalin suppressed all opposition to his rule, committed the state ideology to Marxism–Leninism. As a result, the country underwent a period of rapid industrialization and collectivization which laid the foundation for its victory in World War II and postwar dominance of Eastern Europe. Shortly before World War II, Stalin signed the Molotov–Ribbentrop Pact agreeing to non-aggression with Nazi Germany, in June 1941, the Germans invaded the Soviet Union, opening the largest and bloodiest theater of war in history. Soviet war casualties accounted for the highest proportion of the conflict in the effort of acquiring the upper hand over Axis forces at battles such as Stalingrad. Soviet forces eventually captured Berlin in 1945, the territory overtaken by the Red Army became satellite states of the Eastern Bloc. The Cold War emerged by 1947 as the Soviet bloc confronted the Western states that united in the North Atlantic Treaty Organization in 1949. Following Stalins death in 1953, a period of political and economic liberalization, known as de-Stalinization and Khrushchevs Thaw, the country developed rapidly, as millions of peasants were moved into industrialized cities. The USSR took a lead in the Space Race with Sputnik 1, the first ever satellite, and Vostok 1. In the 1970s, there was a brief détente of relations with the United States, the war drained economic resources and was matched by an escalation of American military aid to Mujahideen fighters. In the mid-1980s, the last Soviet leader, Mikhail Gorbachev, sought to reform and liberalize the economy through his policies of glasnost. The goal was to preserve the Communist Party while reversing the economic stagnation, the Cold War ended during his tenure, and in 1989 Soviet satellite countries in Eastern Europe overthrew their respective communist regimes. This led to the rise of strong nationalist and separatist movements inside the USSR as well, in August 1991, a coup détat was attempted by Communist Party hardliners. It failed, with Russian President Boris Yeltsin playing a role in facing down the coup. On 25 December 1991, Gorbachev resigned and the twelve constituent republics emerged from the dissolution of the Soviet Union as independent post-Soviet states

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

Caliber
–
In guns, particularly firearms, caliber or calibre is the approximate internal diameter of the barrel, or the diameter of the projectile it fires, in hundredths or sometimes thousandths of an inch. For example, a 45 caliber firearm has a diameter of.45 of an inch. Barrel diameters can also be expressed using metric dimensions, as in 9mm pistol, when the barrel diameter is given in inches, the abbreviation cal can be used. Good performance requires a bullet to closely match the diameter of a barrel to ensure a good seal. While modern cartridges and cartridge firearms are referred to by the cartridge name. Firearm calibers outside the range of 17 to 50 exist, but are rarely encountered. Larger calibers, such as.577.585.600.700, the.950 JDJ is the only known cartridge beyond 79 caliber used in a rifle. Referring to artillery, caliber is used to describe the length as multiples of the bore diameter. A 5-inch 50 calibre gun has a diameter of 5 in. The main guns of the USS Missouri are 1650 caliber, makers of early cartridge arms had to invent methods of naming the cartridges, since no established convention existed then. One of the early established cartridge arms was the Spencer repeating rifle, later various derivatives were created using the same basic cartridge, but with smaller-diameter bullets, these were named by the cartridge diameter at the base and mouth. The original No.56 became the. 56-56, and the smaller versions. 56-52. 56-50, the. 56-52, the most common of the new calibers, used a 50-cal bullet. Optionally, the weight in grains was designated, e. g. 45-70-405. Variations on these methods persist today, with new cartridges such as the.204 Ruger, metric diameters for small arms refer to cartridge dimensions and are expressed with an × between the bore diameter and the length of the cartridge case, for example,7. 62×51 NATO. This indicates that the diameter is 7. 62mm, loaded in a case 51mm long. Similarly, the 6. 5×55 Swedish cartridge has a diameter of 6.5 mm. An exception to rule is the proprietary cartridge used by U. S. maker Lazzeroni. The following table lists commonly used calibers where both metric and imperial are used as equivalents
