ASU-57 Paradrop Sequence
The ASU-57 was a small, lightly constructed Soviet assault gun specifically designed for use by Soviet airborne divisions. From 1960 onwards, it was gradually phased out in favour of the ASU-85. Development history The task to develop a lightweight assault gun for the airborne troops (with either a 57 mm gun or a 76 mm gun) was given to two design bureaus, Astrov (OKB-40) in Mytishchi and Kravtsev in Moscow. Nikolaj Astrov's OKB-40 designed the ASU-76, based on components of the T-70 light tank and the SU-76 assault gun, and armed with the new 76 mm gun D-56T. The ASU-76 turned out to be too heavy, even though the armour was only 3 mm thick, and the project was cancelled. Anatoly Kravtsev's team came up with the similar, amphibious K-73. This vehicle was armed with Charnko's 57 mm anti-tank gun Ch-51 and was even more thinly armoured than the ASU-76. This project too was shelved. In 1949, Astrov was instructed to continue with his project, but with reduc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

T-70
The T-70 was a light tank used by the Red Army during World War II, replacing both the T-60 scout tank for reconnaissance and the T-50 light infantry tank for infantry support. The T-80 light tank was a more advanced version of the T-70 with a two-man turret—it was produced only in very small numbers when light tank production was abandoned. The T-90 self-propelled anti-aircraft gun was a prototype vehicle with twin machine guns, based on the T-70 chassis. The T-70 was armed with a 45-mm L/46 gun Model 38 with forty-five rounds carried, and a coaxial 7.62-mm DT machine gun. The tank was operated by a driver and a commander who loaded and fired the gun. Armour thickness on the turret front was 60 mm, turret sides and rear: 35 mm, hull front and sides: 45 mm, roof and bottom: 10 mm. Production history By 1942, light tanks were considered inadequate by the Red Army, unable to keep up with the T-34 medium tank and unable to penetrate the armour of most ...

Aluminum
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity towards ox ...

Welded
Welding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion. Welding is distinct from lower temperature techniques such as brazing and soldering, which do not melt the base metal (parent metal). In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that, based on weld configuration (butt, full penetration, fillet, etc.), can be stronger than the base material. Pressure may also be used in conjunction with heat or by itself to produce a weld. Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated or oxidized. Many different energy sources can be used for welding, including a gas flame (chemical), an electric arc (electrical), a laser, an electron beam, friction, and ultrasound. While often an indust ...

Division (military)
A division is a large military unit or Formation (military), formation, usually consisting of between 6,000 and 25,000 soldiers. In most armies, a division is composed of several regiments or brigades; in turn, several divisions typically make up a corps. Historically, the division has been the default combined arms unit capable of independent Military tactics, operations. Smaller combined arms units, such as the American regimental combat team (RCT) during World War II, were used when conditions favored them. In recent times, modern Western militaries have begun adopting the smaller brigade combat team (similar to the RCT) as the default combined arms unit, with the division they belong to being less important. While the focus of this article is on army divisions, in naval usage "division (naval), division" has a completely different meaning, referring to either an administrative/functional sub-unit of a department (e.g., fire control division of the weapons department) aboar ...

M2 Browning
The M2 machine gun or Browning .50 caliber machine gun (informally, "Ma Deuce") is a heavy machine gun that was designed towards the end of World War I by John Browning. Its design is similar to Browning's earlier M1919 Browning machine gun, which was chambered for the .30-06 cartridge. The M2 uses Browning's larger and more powerful .50 BMG (12.7 mm) cartridge. The design has had many designations; the official U.S. military designation for the current infantry type is Browning Machine Gun, Cal. .50, M2, HB, Flexible. It is effective against infantry, unarmored or lightly armored vehicles and boats, light fortifications, and low-flying aircraft. The gun has been used extensively as a vehicle weapon and for aircraft armament by the United States since the 1930s. It was heavily used during World War II, the Korean War, the Vietnam War, the Falklands War, the Soviet–Afghan War, the Gulf War, the Iraq War, and the War in Afghanistan. It is the primary heavy machine gun of NATO ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GAZ-M20 Pobeda
The GAZ-M20 "Pobeda" (russian: ГАЗ-М20 Победа; ''победа'' means ''victory'') was a passenger car produced in the Soviet Union by GAZ from 1946 until 1958. It was also licensed to the Polish Passenger Automobile Factory and produced as the FSO Warszawa. Although usually known as the GAZ-M20, an original car's designation at that time was just M-20: M for "Molotovets" (the GAZ factory was named after Vyacheslav Molotov). History The first sketches of similar-looking cars were completed by Valentin Brodsky in 1938 and by Vladimir Aryamov in 1940, which revealed a growing tendency towards streamlined car design in the Soviet Union. Aryamov's two-door coupe GAZ-11-80, designed in 1940, greatly resembled the later Pobeda and was in many ways identical to it. However, after the German invasion of 1941 military priorities delayed the work on the new car and the factory was switched to military production. The first Pobeda was developed in the Soviet Union under chief engin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DShK
The DShK 1938 (Cyrillic: ДШК, for russian: Дегтярёва-Шпагина Крупнокалиберный, Degtyaryova-Shpagina Krupnokaliberny, links=no, "Degtyaryov-Shpagin large-calibre") is a Soviet heavy machine gun with a V-shaped butterfly trigger, firing the 12.7×108mm cartridge. The weapon was also used as a heavy infantry machine gun, where it was frequently deployed with a two-wheeled mounting and a single-sheet armour-plate shield. The DShK's name is derived from its original designer, Vasily Degtyaryov, and Georgi Shpagin, who later improved the cartridge feed mechanism. It is sometimes nicknamed Dushka (a dear or beloved person) in Russian-speaking countries, from the abbreviation. Alongside the American M2 Browning, the DShK is the only .50 caliber machine gun designed prior to World War II that remains in service to the present day. History Requiring a heavy machine gun similar to the M2 Browning, development of the DShK began in the Soviet Union in 1929 an ...

ZIS-2
The ZiS-2 (russian: ЗиС-2) (GRAU index: 52-P-271) is a Soviet 57 mm anti-tank gun used during World War II. The ZiS-4 is a version of the gun that was meant to be installed in tanks. ''ZiS'' stands for ''Zavod imeni Stalina'' (Russian ''Завод имени Сталина'', 'Factory named after Stalin'), the official title of Artillery Factory No. 92, which produced the gun first. Development In the beginning of 1940 the design office of V. G. Grabin received a task from the artillery department to develop a powerful anti-tank gun. The head of this department, Marshal Kulik, and his subordinates estimated that the use of heavily armoured tanks by the USSR in the Winter War would not have gone unnoticed in Nazi Germany and would lead to the development of similar fighting machines there. There is also a chance that the department was influenced by German propaganda about the experimental multi-turreted "supertank" NbFz, ie. heavier armour was attributed to this vehicle th ...

Parachute
A parachute is a device used to slow the motion of an object through an atmosphere by creating drag or, in a ram-air parachute, aerodynamic lift. A major application is to support people, for recreation or as a safety device for aviators, who can exit from an aircraft at height and descend safely to earth. A parachute is usually made of a light, strong fabric. Early parachutes were made of silk. The most common fabric today is nylon. A parachute's canopy is typically dome-shaped, but some are rectangles, inverted domes, and other shapes. A variety of loads are attached to parachutes, including people, food, equipment, space capsules, and bombs. History Middle Ages In 852, in Córdoba, Spain, the Moorish man Armen Firman attempted unsuccessfully to fly by jumping from a tower while wearing a large cloak. It was recorded that "there was enough air in the folds of his cloak to prevent great injury when he reached the ground." Early Renaissance The earliest evidence f ...

An-12
The Antonov An-12 (Russian: Антонов Ан-12; NATO reporting name: Cub) is a four-engined turboprop transport aircraft designed in the Soviet Union. It is the military version of the Antonov An-10 and has many variants. For more than three decades the An-12 was the standard medium-range cargo and paratroop transport aircraft of the Soviet air forces. A total of 1,248 were eventually built. Design and development Developed from the Antonov An-8, the An-12 was a military version of the An-10 passenger transport. The first prototype An-12 flew in December 1957 and entered Soviet military service in 1959. Initially, the aircraft was produced at the State Aviation Factory in Irkutsk. From 1962, production was transferred to Tashkent, where 830 were built. Later, production moved to Voronezh and Kazan. In military use, the An-12 has capacity for up to 100 fully equipped paratroopers or 20,000 kg (44,090 lb) of cargo, which is loaded through the rear loading ramp/door. ...
