2K1 Mars
The Mars (NATO reporting name FROG-2, GRAU index 2K1) was a Soviet solid-fuel tactical missile system with a range of 7 to 18 km. The chief designer was N. P. Mazur. * Weight of launcher: 15 tons, based on PT-76 tank * rocket engine: 3R1 * missile diameter: 1.75 m * guidance: by launcher * maximum speed of launcher: 35 km/h History Background At 3 meters long, between 0.7 and 1.5 meters in diameter, and weighing 4-5 tons, the earliest nuclear weapons were so large and heavy that they could only be carried by strategic bombers such as the United States Boeing B-29 Superfortress, Convair B-36 Peacemaker and the Soviet Tupolev Tu-4. However, use of these aircraft in the 1950s for nuclear strikes on forward positions of enemy troops in a theatre of military operations was impractical. By the mid-1950s, nuclear weapons development led to increases in their power and technical characteristics while reducing their diameters and masses, and therefore creating the possibi ...

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a Federation, federal union of Republics of the Soviet Union, fifteen national republics; in practice, both Government of the Soviet Union, its government and Economy of the Soviet Union, its economy were highly Soviet-type economic planning, 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 Soviet Federative Socialist Republic, Russian SFSR. Other major cities included Saint Petersburg, Leningrad (Russian SFSR), Kyiv, Kiev (Ukrainian Soviet Socialist Republic, Ukrainian SSR), Minsk (Byelorussian Soviet Socialist Republic, Byelorussian SSR), Tas ...

Tupolev Tu-4
The Tupolev Tu-4 (russian: Туполев Ту-4; NATO reporting name: Bull) is a piston-engined Soviet strategic bomber that served the Soviet Air Force from the late 1940s to mid-1960s. It was reverse-engineered from the American Boeing B-29 Superfortress. Design and development Toward the end of World War II, the Soviet Union saw the need for a strategic bombing capability similar to that of the United States Army Air Forces. The Soviet VVS air arm had the locally designed Petlyakov Pe-8 four-engined "heavy" in service at the start of the war, but only 93 had been built by the end of the war and the type had become obsolete. The U.S. regularly conducted bombing raids on Japan, from distant Pacific forward bases using B-29 Superfortresses. Joseph Stalin ordered the development of a comparable bomber. The U.S. twice refused to supply the Soviet Union with B-29s under Lend Lease. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cold War Weapons 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, because ...

Rocket Artillery
Rocket artillery is artillery that uses rocket explosives as the projectile. The use of rocket artillery dates back to medieval China where devices such as fire arrows were used (albeit mostly as a psychological weapon). Fire arrows were also used in multiple launch systems and transported via carts. First true rocket artillery was developed in India by the Kingdom of Mysore. In the late nineteenth century, due to improvements in the power and range of conventional artillery, the use of early military rockets declined; they were finally used on a small scale by both sides during the American Civil War. Modern rocket artillery was first employed during World War II, in the form of the German Nebelwerfer family of rocket ordnance designs, Soviet Katyusha-series and numerous other systems employed on a smaller scale by the Western allies and Japan. In modern use, the rockets are often guided by an internal guiding system or GPS in order to maintain accuracy. History Early histor ...

Circular Error Probable
In the military science of ballistics, circular error probable (CEP) (also circular error probability or circle of equal probability) is a measure of a weapon system's precision. It is defined as the radius of a circle, centered on the mean, whose perimeter is expected to include the landing points of 50% of the rounds; said otherwise, it is the median error radius. That is, if a given munitions design has a CEP of 100 m, when 100 munitions are targeted at the same point, 50 will fall within a circle with a radius of 100 m around their average impact point. (The distance between the target point and the average impact point is referred to as bias.) There are associated concepts, such as the DRMS (distance root mean square), which is the square root of the average squared distance error, and R95, which is the radius of the circle where 95% of the values would fall in. The concept of CEP also plays a role when measuring the accuracy of a position obtained by a navig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2B1 Oka
2B1 Oka (russian: 2Б1 Ока) is a Soviet 420 mm self-propelled heavy artillery. ''2B1'' is its GRAU designation. Development An experimental model was ready in 1957. Its chassis (Object 273), was designed and built by the Kirov Plant. Its 20-meter barrel allowed it to fire 750 kg rounds up to 45 km. Due to its complexity of loading it had a relatively low rate of fire—one round every five minutes. Field tests showed various drawbacks of the entire design (the recoil was too strong for many components: it damaged drive sprockets, ripped the gear-box away from its mountings, etc.) and the sheer length rendered it incredibly difficult to transport. Its development continued until 1960, when the idea of such overpowered guns (along with the 2A3), was abandoned in favor of tactical ballistic missiles, such as the 2K6 Luna.

SM-54
The 2A3 Kondensator 2P (russian: 2А3 «Конденсатор» - "Condenser" or "Capacitor") was a Soviet 406 mm self-propelled howitzer. Its GRAU designation is 2A3. Development The 2A3 originated during the Cold War as a response to the United States' new " Pentomic Division" tactical doctrine that emphasized heavy use of tactical nuclear weapons, including nuclear artillery. The US M65 cannon was introduced in 1952 and deployed in Germany in 1953. The Soviet Union started its own program to develop a 406mm self-propelled howitzer capable of firing nuclear projectiles, codenamed 'Objekt 271'. Grabin Design Bureau completed the artillery system in 1955. The 'Objekt 271' chassis from the Kotlin Design Bureau in Leningrad was completed soon thereafter. The unified system received the military industrial designation 2A3 and was completed in 1956 at the Kirov Works in Leningrad. Total production only amounted to four vehicles. Western observers got their first look ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Convair B-36 Peacemaker
The Convair B-36 "Peacemaker" is a strategic bomber that was built by Convair and operated by the United States Air Force (USAF) from 1949 to 1959. The B-36 is the largest mass-produced Reciprocating engine, piston-engined aircraft ever built. It had the longest wingspan of any combat aircraft ever built, at . The B-36 was the first bomber capable of delivering any of the nuclear weapons in the U.S. arsenal from inside its four bomb bays without aircraft modifications. With a range of and a maximum payload of , the B-36 was capable of intercontinental flight without refuelling. Entering service in 1948, the B-36 was the primary nuclear weapons delivery vehicle of Strategic Air Command (SAC) until it was replaced by the jet-powered Boeing B-52 Stratofortress beginning in 1955. All but four aircraft have been scrapped. Development The genesis of the B-36 can be traced to early 1941, prior to the entry of the United States into World War II. At the time, the threat existed that Bat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NATO Reporting Name
NATO reporting names are code names for military equipment from Russia, China, and historically, the Eastern Bloc (Soviet Union and other nations of the Warsaw Pact). They provide unambiguous and easily understood English words in a uniform manner in place of the original designations, which either may have been unknown to the Western world at the time or easily confused codes. For example, the Russian bomber jet Tupolev Tu-160 is simply called "Blackjack". NATO maintains lists of the names. The assignment of the names for the Russian and Chinese aircraft was once managed by the five-nation Air Standardization Coordinating Committee (ASCC), but that is no longer the case. American variations The United States Department of Defense (DOD) expands on the NATO reporting names in some cases. NATO refers to surface-to-air missile systems mounted on ships or submarines with the same names as the corresponding land-based systems, but the US DoD assigns a different series of numbers wi ...

Boeing B-29 Superfortress
The Boeing B-29 Superfortress is an American four-engined propeller-driven heavy bomber, designed by Boeing and flown primarily by the United States during World War II and the Korean War. Named in allusion to its predecessor, the B-17 Flying Fortress, the Superfortress was designed for high-altitude strategic bombing, but also excelled in low-altitude night incendiary bombing, and in dropping naval mines to blockade Japan. B-29s dropped the atomic bombs on Hiroshima and Nagasaki, the only aircraft ever to drop nuclear weapons in combat. One of the largest aircraft of World War II, the B-29 was designed with state-of-the-art technology, which included a pressurized cabin, dual-wheeled tricycle landing gear, and an analog computer-controlled fire-control system that allowed one gunner and a fire-control officer to direct four remote machine gun turrets. The $3 billion cost of design and production (equivalent to $ billion today), far exceeding the $1.9 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strategic Bombers
A strategic bomber is a medium- to long-range penetration bomber aircraft designed to drop large amounts of air-to-ground weaponry onto a distant target for the purposes of debilitating the enemy's capacity to wage war. Unlike tactical bombers, penetrators, fighter-bombers, and attack aircraft, which are used in air interdiction operations to attack enemy combatants and military equipment, strategic bombers are designed to fly into enemy territory to destroy strategic targets (e.g., infrastructure, logistics, military installations, factories, etc.). In addition to strategic bombing, strategic bombers can be used for tactical missions. There are currently only three countries that operate strategic bombers: the United States, Russia and China. The modern strategic bomber role appeared after strategic bombing was widely employed, and atomic bombs were first used in combat during World War II. Nuclear strike missions (i.e., delivering nuclear-armed missiles or bombs) can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
