122 Mm Howitzer 2A18 (D-30)
The 122-mm howitzer D-30 ( GRAU index 2A18) is a Soviet howitzer that first entered service in 1960. It is a robust piece that focuses on the essential features of a towed field gun suitable for all conditions. The D-30 has a maximum range of 15.4 kilometers, or over 21 km using rocket-assisted projectile ammunition. With its striking three-leg mounting, the D-30 can be rapidly traversed through 360 degrees. Although no longer manufactured in the nations of the former Soviet Union, the D-30 is still manufactured internationally and is in service in more than 60 countries' armed forces. The barrel assembly of the 2A18 gun is used by the 2S1 self-propelled howitzer. There are also Egyptian, Chinese, Serbian and Syrian self-propelled variants and conversions. The Syrian conversion utilizes the hull of a T-34 tank. History The 122 mm (originally 48 lines) calibre was adopted by Russia in the early 20th century, becoming very important to Soviet artil ...

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

2020 Nagorno-Karabakh War
The Second Nagorno-Karabakh War was an armed conflict in 2020 that took place in the disputed region of Nagorno-Karabakh and Armenian-occupied territories surrounding Nagorno-Karabakh, the surrounding territories. It was a major escalation of an unresolved Nagorno-Karabakh conflict, conflict over the region, involving Azerbaijan, Armenia and the Political status of Nagorno-Karabakh, self-declared Armenian breakaway state of Republic of Artsakh, Artsakh. The war lasted for more than a month and resulted in Azerbaijani victory, with Armenia ceding the Armenian-occupied territories surrounding Nagorno-Karabakh, territories it had occupied in 1994 surrounding Nagorno-Karabakh. The defeat ignited 2020–2021 Armenian protests, anti-government protests in Armenia. Post-war skirmishes continued in the region, including September 2022 Armenia–Azerbaijan clashes, substantial clashes in 2022. Fighting began on the morning of 27 September, with an Azerbaijani offensive along the Nagorn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
122 mm Howitzer M1938 (M-30)
The 122 mm howitzer M1938 (M-30) (GRAU index: 52-G-463) was a Soviet 121.92 mm (4.8 inch) howitzer. The weapon was developed by the design bureau of Motovilikha Plants, headed by F. F. Petrov, in the late 1930s, and was in production from 1939 to 1955. The M-30 saw action in World War II, mainly as a divisional artillery piece of the Red Army (RKKA). Captured guns were also employed later in the conflict by the German Wehrmacht and the Finnish Army. Post World War II the M-30 saw combat in numerous conflicts of the mid- to late twentieth century in service of other countries' armies, notably in the Middle East. Development In 1930 Red Army (RKKA) authorities started to look for a new divisional-level howitzer to replace the pre-World War I 122 mm howitzer M1909 and 122 mm howitzer M1910. Although both pieces were eventually modernized, resulting in the 122-mm howitzer M1909/37 and the 122-mm howitzer M1910/30 respectively, these upgrades did not address some shortc ...

Line (unit)
The line (abbreviated L or l or ‴ or lin.) was a small English unit of length, variously reckoned as , , , or of an inch. It was not included among the units authorized as the British Imperial system in 1824. Size The line was not recognized by any statute of the English Parliament but was usually understood as of a barleycorn, which itself was recognized by statute as of an inch. The line was eventually decimalized as of an inch, without recourse to barleycorns. The US button trade uses the same or a similar term but defined as one-fortieth of the US-customary inch (making a button-maker's line equal to 0.635 mm). In use Botanists formerly used the units (usually as inch) to measure the size of plant parts. Linnaeus's ''Philosophia botanica'' (1751) includes the Linea in its summary of units of measurements, defining it as "Linea una Mensurae parisinae"; Stearns gives its length as 2.25 mm. Even after metrication, British botanists continued to employ tool ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-34
The T-34 is a Soviet medium tank introduced in 1940. When introduced its 76.2 mm (3 in) tank gun was less powerful than its contemporaries while its 60-degree sloped armour provided good protection against Anti-tank warfare, anti-tank weapons. The Christie suspension was inherited from the design of American J. Walter Christie's M1928 tank, versions of which were sold turret-less to the Red Army and documented as "farm tractors", after being rejected by the U.S. Army. The T-34 had a profound effect on the conflict on the Eastern Front (World War II), Eastern Front in the World War II, Second World War, and had a short lasting impact on tank design. After the Germans encountered the tank in 1941 during Operation Barbarossa, German general Paul Ludwig Ewald von Kleist called it "the finest tank in the world" and Heinz Guderian affirmed the T-34's "vast superiority" over German tanks. Alfred Jodl, chief of operations staff of the German armed forces noted in his war diar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Post-Soviet States
The post-Soviet states, also known as the former Soviet Union (FSU), the former Soviet Republics and in Russia as the near abroad (russian: links=no, ближнее зарубежье, blizhneye zarubezhye), are the 15 sovereign states that were union republics of the Soviet Union, which emerged and re-emerged from the Soviet Union following its dissolution in 1991. Russia is the primary ''de facto'' internationally recognized successor state to the Soviet Union after the Cold War; while Ukraine has, by law, proclaimed that it is a state-successor of both the Ukrainian SSR and the Soviet Union which remained under dispute over formerly Soviet-owned properties. The three Baltic states – Estonia, Latvia, and Lithuania – were the first to declare their independence from the USSR, between March and May 1990, claiming continuity from the original states that existed prior to their annexation by the Soviet Union in 1940. The remaining 12 republics all subsequently seceded, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Field Gun
A field gun is a field artillery piece. Originally the term referred to smaller guns that could accompany a field army on the march, that when in combat could be moved about the battlefield in response to changing circumstances ( field artillery), as opposed to guns installed in a fort (garrison artillery or coastal artillery), or to siege cannons and mortars which are too large to be moved quickly, and would be used only in a prolonged siege. Perhaps the most famous use of the field gun in terms of advanced tactics was Napoleon Bonaparte's use of very large wheels on the guns that allowed them to be moved quickly even during a battle. By moving the guns from point-to-point during a battle, enemy formations could be broken up to be handled by the infantry or cavalry wherever they were massing, dramatically increasing the overall effectiveness of the attack. World War I As the evolution of artillery continued, almost all guns of any size became capable of being moved at some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Howitzer
A howitzer () is a long- ranged weapon, falling between a cannon (also known as an artillery gun in the United States), which fires shells at flat trajectories, and a mortar, which fires at high angles of ascent and descent. Howitzers, like other artillery equipment, are usually organized in a group called a battery. Howitzers, together with long-barreled guns, mortars, and rocket artillery, are the four basic types of modern artillery. Mortars fire at angles of elevation greater than 45°, and are useful for mountain warfare because the projectile could go over obstacles. Cannons fire at low angles of elevation (<45°), and the projectile lands much faster at its target than it would in the case of a mortar. But the cannon is not useful if there is an obstacle like a hill/wall in front of its target. Etymology The English word ''howitzer'' comes from the Czech word , from , 'crowd', and is in turn a borrowing from the Middle High German word or (mode ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GRAU
The Main Missile and Artillery Directorate of the Ministry of Defense of the Russian Federation (), commonly referred to by its transliterated Russian acronym GRAU (), is a department of the Russian Ministry of Defense. It is subordinate to the Chief of Armament and Munition of the Russian Armed Forces, a vice-minister of defense. The organization dates back to 1862 when it was established under the name Главное артиллерийское управление (ГАУ – GAU). The "R" from "rockets" was added to the title in 1960. In particular, the GRAU is responsible for assigning GRAU indices to Russian army munitions and equipment. Arsenals of the GRAU, according to Kommersant-Vlast in 2005, include the 60th at Kaluga, the 55th at Rzhev, the 75th at Serpukhov south of Moscow, (all three in the Moscow Military District) and the 80th at Gagarskiy, the 116th at Krasno-Oktyabrskiy and the 5th, all in the Volga–Urals Military District.Kommersant-Vlast, Vys Rossik ...

Hydraulic Recoil Mechanism
A hydraulic recoil mechanism is a way of limiting the effects of recoil and adding to the accuracy and firepower of an artillery piece. Description The usual recoil system in modern quick-firing guns is the hydro-pneumatic recoil system. In this system, the barrel is mounted on rails on which it can recoil to the rear, and the recoil is taken up by a cylinder which is similar in operation to an automotive gas-charged shock absorber, and is commonly visible as a cylinder mounted parallel to the barrel of the gun, but shorter and smaller than it. The cylinder contains a charge of compressed air, as well as hydraulic oil; in operation, the barrel's energy is taken up in compressing the air as the barrel recoils backward, then is dissipated via hydraulic damping as the barrel returns forward to the firing position. The recoil impulse is thus spread out over the time in which the barrel is compressing the air, rather than over the much narrower interval of time when the project ...

Rifled Breech Loader
A rifled breech loader (RBL) is an artillery piece which, unlike the smoothbore cannon and rifled muzzle loader (RML) which preceded it, has rifling in the barrel and is loaded from the breech at the rear of the gun. The spin imparted by the gun's rifling gives projectiles directional stability and increased range. Loading from the rear of the gun leaves the crew less exposed to enemy fire, allows smaller gun emplacements or turrets, and allows a faster rate of fire. Overview The major problem to be solved with breechloading artillery was obturation: the sealing of the breech after firing to ensure that none of the gases generated by the burning of the propellant (initially gunpowder) escaped rearwards through the breech. 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 and open it after firing as quickly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rocket-assisted Projectile
A rocket-assisted projectile (RAP) is a cannon, howitzer, Mortar (weapon), mortar, or recoilless rifle round incorporating a rocket motor for independent propulsion. This gives the projectile greater speed and range than a non-assisted Ballistics, ballistic shell, which is propelled only by the gun's exploding charge. Some forms of rocket-assisted projectiles can be outfitted with a laser-guide for greater accuracy. The German Sturmtiger (1944) used a 380 mm Rocket Propelled Round as its main projectile. These rounds were high explosive shells or shaped charges with a maximum range of 6,000 m. The gun first accelerated the projectile to 45 m/s (150 ft/s), the 40 kg (88 lb) rocket charge then boosted this to about 250 m/s (820 ft/s). Also the German Krupp K5 railway gun of World War 2 used rocket assisted projectiles in the later stages of the war, although it also used conventional artillery projectiles. The North Korean Koksan (artillery), M-1978 / M1989 (KOKSAN) 170mm self ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
