AK-230
The AK-230 is a Soviet fully automatic naval twin 30 mm gun. Its primary function is anti-aircraft. It is mounted in an enclosed automatic turret and directed by radar. AK-230 is widely used, mounted on big warships as well as small craft. About 1450 guns were produced in the USSR, and about 300 were produced in China as the Type 69. It was succeeded by the more powerful AK-630 from the mid-to-late 1970s. Development and service Development of the weapon began during the 1950s, with the first trial weapon fitted to the ''Osa'' class of fast attack missile boats and ''Shershen'' class torpedo boats. The weapon was officially accepted into service in 1969. Its service life was relatively short, due to the fielding of the AK-630 system in the mid-1970s, which uses the same mountings and can be controlled by the same fire control systems. While its 30×210 mm round was much more powerful than the AK-630's 30×165 mm one, having the muzzle velocity of 1050 m/s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osa-class Missile Boat
The Project 205 Moskit (''mosquito'') more commonly known by their NATO reporting name Osa, are a class of missile boats developed for the Soviet Navy in the late 1950s. Until 1962 this was classified as a large torpedo boat. The Osa class is probably the most numerous class of missile boats ever built, with over 400 vessels constructed between 1960 and 1973 for both the Soviet Navy and for export to allied countries. "Osa" means "wasp" in Russian, but it is not an official name. The boats were designated as "large missile cutters" in the Soviet Navy. Origins While the earlier Komar class were cheap and efficient boats (and the first to sink a warship with guided missiles, destroying the Israeli Navy's ''Eilat''), their endurance, sea keeping, and habitability were modest at best, and the missile box was vulnerable to damage from waves. Among their other weak points were the wooden hull, the radar set lacking a fire control unit, and an inadequate defensive armament consisti ...

Shershen-class Torpedo Boat
The Shershen class was the NATO reporting name for a class of torpedo boats built for the Soviet Navy and allies. The Soviet designation was Project 206 ''Shtorm''. Development Designated as TKAs ( ru. ''Torpednyy Kater''; eng. ''Torpedo Cutter''), the Project 183 boats were designed as simple fast attack craft suitable for cheap manufacture and easy maintenance. Intended as a successor to the Project 183 "Bolshevik" torpedo boats, development of the new class started in 1956. Like other similar boats, they were to be used near the coast, in good weather and under friendly air cover. The first boat was completed at the Yaroslavl Shipyard and commissioned with the Soviet Navy in October 1960. Production was also organized at the Sredne-Nevskiy and Sosnovskiy Shipyard with a total of 80 boats being built at all three shipyards. A simplified export version was designated Project 206E (NATO designation Mol). Beside Soviet shipyards, Tito's Kraljevica Shipyard in SFR Yugoslavia l ...

AK-630
The AK-630 is a Soviet and Russian fully automatic naval, rotary cannon, close-in weapon system. The "630" designation refers to the weapon's six gun barrels and their 30 mm caliber. The system is mounted in an enclosed automatic turret and directed by MR-123 radar and television detection and tracking. The weapon's primary purpose is defense against aircraft and helicopters. Effectiveness against anti-ship missiles and other precision-guided weapons is limited due to the limitations of the radar and aiming system and due to the dispersion of a short-barreled gun. The AK-630 can also be employed against ships and other small craft, coastal targets, and floating mines. Once operational, the system was rapidly adopted and installed in every new Soviet warship (from mine-hunters to aircraft carriers) with up to eight units on larger vessels; hundreds have been produced in total. Description The complete weapon system is called A-213-Vympel-A, which comprises the AK-630M Gun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revolver Cannon
A revolver cannon is a type of autocannon, commonly used as an aircraft gun. It uses a cylinder with multiple chambers, like those of a revolver handgun, to speed up the loading-firing-ejection cycle. Some examples are also power-driven, to further speed the loading process. Unlike a rotary cannon, a revolver cannon only has a single barrel, so its spun weight is lower. Automatic revolver cannons have been produced by many different manufacturers. History Precursors An early precursor was the Puckle gun of 1718, a large flintlock revolver gun, manually operated. The design idea was impractical, far ahead of what 18th century technology could achieve. During the 19th century, Elisha Collier and later Samuel Colt used the revolver action to revolutionize handguns. The Confederate States of America used a single 2-inch, 5-shot revolver cannon with manually rotated chambers during the Siege of Petersburg. The gun was captured in Danville, Virginia by Union forces on Apri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CIWS
A close-in weapon system (CIWS ) is a point-defense weapon system for detecting and destroying short-range incoming missiles and enemy aircraft which have penetrated the outer defenses, typically mounted on a naval ship. Nearly all classes of larger modern warships are equipped with some kind of CIWS device. There are two types of CIWS systems. A gun-based CIWS usually consists of a combination of radars, computers, and rapid-firing multiple-barrel rotary cannons placed on a rotating turret. Missile-based CIWSs use either infra-red, passive radar/ ESM, or semi-active radar terminal guidance to guide missiles to the targeted enemy aircraft or other threats. In some cases, CIWS are used on land to protect military bases. In this case, the CIWS can also protect the base from shell and rocket fire. Gun systems A gun-based CIWS usually consists of a combination of radars, computers and rotary or revolver cannon placed on a rotating, automatically aimed gun mount. Examp ...

Tasma I Luska Do AK-230
Tasma ( Russian: ''Тасма'') is a Russian GOST and ISO certified manufacturer of black-and-white and colour photographic films. It also manufactures adhesive tape and demineralized water. Located in Kazan, Russia, it has been in operation since 1933 (starting as "Film Factory No. 8"). The name ''Tasma'' is derived from the Russian phrase ''Татарские светочувствительные материалы'' ("''Tatarskie Sveto Materialiy''"), meaning "Tatar Sensitized Materials"; this name was adopted by the company in 1974. During World War II, only Tasma's Kazan factory remained in operation, supplying the entirety of domestic Soviet photographic material for the war effort. For this effort, it was awarded a medal for the Order of the Red Banner of Labor in 1944. The company manufactures black and white negative films KN-1, KN-2, and KN-3, which are popular with photographers in Russia as well as motion picture cinematographers internationally. The company provid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold War Artillery Of The Soviet Union
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to on the Celsius scale, on the Fahrenheit scale, and on the Rankine scale. Since temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in the classical sense. The object could be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, becaus ...

30 Mm Artillery
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9t ...

Autocannons Of The Soviet Union
An autocannon, automatic cannon or machine cannon is a fully automatic gun that is capable of rapid-firing large- caliber ( or more) armour-piercing, explosive or incendiary shells, as opposed to the smaller-caliber kinetic projectiles (bullets) fired by a machine gun. Autocannons have a longer effective range and greater terminal performance than machine guns, due to the use of larger/heavier munitions (most often in the range of , but bigger calibers also exist), but are usually smaller than tank guns, howitzers, field guns or other artillery. When used on its own, the word "autocannon" typically indicates a non-rotary weapon with a single barrel. When multiple rotating barrels are involved, such a weapon is referred to as a "rotary autocannon" or occasionally "rotary cannon", for short (particularly on aircraft). Autocannons are heavy weapons that are unsuitable for use by infantry. Due to the heavy weight and recoil, they are typically installed on fixed mounts, ...

Naval Anti-aircraft Guns
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications (brown-water navy), open-ocean applications (blue- ...
