Plokštinė Missile Base
Plokštinė missile base ( lt, Plokštinės raketų bazė) was an underground base of the Soviet Union. It was built near Plokščiai village, north of Plungė, in the sparsely populated Plokštinė forest near Plateliai Lake, Samogitia, Lithuania. This was the first nuclear missile base of the Soviet Union built to house underground R-12 Dvina ( NATO reporting name: SS-4 Sandal) ballistic medium-range missiles. In 2012 a Cold War Museum was opened at the site. History Construction When the United States started building underground military bases in the late 1950s, the Soviet Union felt the need to maintain its military capabilities. Therefore, in September 1960, the Soviet Union started the rapid construction of an underground military base. It was one of the first in the Soviet Union, near the village of Plokščiai in the Lithuanian SSR. The location of the missile base meant that its R-12 Dvina missiles (which had a range of about 2,080 km) could reach all of the Eu ...

R-12 Dvina
The R-12 Dvina was a theatre ballistic missile developed and deployed by the Soviet Union during the Cold War. Its GRAU designation was 8K63 (8K63U or 8K63У in Cyrillic for silo-launched version), and it was given the NATO reporting name of SS-4 Sandal. The R-12 rocket provided the Soviet Union with the capability to attack targets at medium ranges with a megaton-class thermonuclear warhead and constituted the bulk of the Soviet offensive missile threat to Western Europe. Deployments of the R-12 missile in Cuba caused the Cuban Missile Crisis in 1962. A total of 2335 missiles were produced; all were destroyed in 1993 under the START II treaty. As well as the single-stage ballistic technology, the R-12 Dvina had a two-stage capability that allowed payloads to be placed into low Earth orbit. The Iranian Shahab-4 missile is likely an offshoot of the R-12 Dvina. History Beginning OKB-586 formed from a spin-off of portions of Sergei Korolev's OKB-1 production infrastructure und ...

Dome
A dome () is an architectural element similar to the hollow upper half of a sphere. There is significant overlap with the term cupola, which may also refer to a dome or a structure on top of a dome. The precise definition of a dome has been a matter of controversy and there are a wide variety of forms and specialized terms to describe them. A dome can rest directly upon a Rotunda (architecture), rotunda wall, a Tholobate, drum, or a system of squinches or pendentives used to accommodate the transition in shape from a rectangular or square space to the round or polygonal base of the dome. The dome's apex may be closed or may be open in the form of an Oculus (architecture), oculus, which may itself be covered with a roof lantern and cupola. Domes have a long architectural lineage that extends back into prehistory. Domes were built in ancient Mesopotamia, and they have been found in Persian architecture, Persian, Ancient Greek architecture, Hellenistic, Ancient Roman architecture, ...

Heckler & Koch G3
The Heckler & Koch G3 (''Gewehr'' 3) is a 7.62×51mm NATO, select-fire battle rifle developed in the 1950s by the German armament manufacturer Heckler & Koch (H&K) in collaboration with the Spanish state-owned design and development agency CETME (''Centro de Estudios Técnicos de Materiales Especiales''). The modular designed G3 has over the years been exported to over 70 countries and manufactured under licence in at least 15 countries, bringing the total number built to around 7,800,000. The G3 was the service rifle of the armed forces of Germany until it was replaced by the G36 in the 1990s. History The origin of the G3 can be traced back to the final years of World War II when Mauser engineers at the Light Weapon Development Group (''Abteilung 37'') at Oberndorf am Neckar designed the ''Maschinenkarabiner Gerät 06'' (MKb ''Gerät'' 06, "machine carbine device 06") prototype assault rifle chambered for the intermediate 7.92×33mm ''Kurz'' cartridge, first with the '' ...

SA-6
The 2K12 ''"Kub"'' (russian: 2К12 "Куб"; en, cube) (NATO reporting name: SA-6 "Gainful") mobile surface-to-air missile system is a Soviet low to medium-level air defence system designed to protect ground forces from air attack. "2К12" is the GRAU designation of the system. Each 2K12 battery consists of a number of similar tracked vehicles, one of which carries the 1S91 (SURN vehicle, NATO designation "Straight Flush") 25 kW G/ H band radar (with a range of ) equipped with a continuous wave illuminator, in addition to an optical sight. The battery usually also includes four triple-missile transporter erector launchers (TELs), and four trucks, each carrying three spare missiles and a crane. The TEL is based on a GM-578 chassis, while the 1S91 radar vehicle is based on a GM-568 chassis, all developed and produced by MMZ. Development The development of the 2K12 was started after 18 July 1958 at the request of the CPSU Central Committee. The system was set the require ...

Semi-active Radar Homing
Semi-active radar homing (SARH) is a common type of missile guidance system, perhaps the most common type for longer-range Air-to-air missile, air-to-air and surface-to-air missile systems. The name refers to the fact that the missile itself is only a passive radar, passive detector of a radar signal—Radar illumination, provided by an external ("offboard") source—as it reflects off the target (in contrast to active radar homing, which uses an active radar transceiver). Semi-active missile systems use bistatic radar, bistatic continuous-wave radar. The NATO Multiservice tactical brevity code, brevity code for a semi-active radar homing missile launch is Fox (code word), Fox One. Concept The basic concept of SARH is that since almost all detection and tracking systems consist of a radar system, duplicating this hardware on the missile itself is redundant. The weight of a transmitter reduces the range of any flying object, so passive systems have greater reach. In addition, t ...

Gyroscope
A gyroscope (from Ancient Greek γῦρος ''gŷros'', "round" and σκοπέω ''skopéō'', "to look") is a device used for measuring or maintaining orientation and angular velocity. It is a spinning wheel or disc in which the axis of rotation (spin axis) is free to assume any orientation by itself. When rotating, the orientation of this axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum. Gyroscopes based on other operating principles also exist, such as the microchip-packaged MEMS gyroscopes found in electronic devices (sometimes called gyrometers), solid-state ring lasers, fibre optic gyroscopes, and the extremely sensitive quantum gyroscope. Applications of gyroscopes include inertial navigation systems, such as in the Hubble Space Telescope, or inside the steel hull of a submerged submarine. Due to their precision, gyroscopes are also used in gyrotheodolites to maintain direction in tunnel mining. Gyroscopes ca ...

Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastern Bloc
The Eastern Bloc, also known as the Communist Bloc and the Soviet Bloc, was the group of socialist states of Central and Eastern Europe, East Asia, Southeast Asia, Africa, and Latin America under the influence of the Soviet Union that existed during the Cold War (1947–1991). These states followed the ideology of Marxism–Leninism, in opposition to the Capitalism, capitalist Western Bloc. The Eastern Bloc was often called the Second World, whereas the term "First World" referred to the Western Bloc and "Third World" referred to the Non-Aligned Movement, non-aligned countries that were mainly in Africa, Asia, and Latin America but notably also included former Tito–Stalin split, pre-1948 Soviet ally SFR Yugoslavia, which was located in Europe. In Western Europe, the term Eastern Bloc generally referred to the USSR and Central and Eastern European countries in the Comecon (East Germany, Polish People's Republic, Poland, Czechoslovak Socialist Republic, Czechoslovakia, Hungarian ...

Metal Theft
Metal theft is "the theft of items for the value of their constituent metals". It usually increases when worldwide prices for scrap metal rise, as has happened dramatically due to rapid industrialization in India and China. Apart from precious metals like gold and silver, the metals most commonly stolen are non-ferrous metals such as copper, aluminium, brass, and bronze. However, even cast iron and steel are seeing higher rates of theft due to increased scrap metal prices. One defining characteristic of metal theft is the motivation. Whereas other items are generally stolen for their extrinsic value, items involved in metal theft are stolen for their intrinsic value as raw material or commodities. Thefts often have negative consequences much greater than the value of the metal stolen, such as the destruction of valuable statues, power interruptions, and the disruption of railway traffic. Items often stolen Anything made of metal has value as scrap metal, and can be stolen: * Man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Exploration
Urban exploration (often shortened as UE, urbex and sometimes known as roof and tunnel hacking) is the exploration of manmade structures, usually abandoned ruins or hidden components of the manmade environment. Photography and historical interest/documentation are heavily featured in the hobby and it sometimes involves trespassing onto private property. Urban exploration is also called draining (a specific form of urban exploration where storm drains or sewers are explored), urban spelunking, urban rock climbing, urban caving, building hacking, or mousing. The activity presents various risks, including both physical danger and, if done illegally and/or without permission, the possibility of arrest and punishment. Some activities associated with urban exploration violate local or regional laws and certain broadly interpreted anti-terrorism laws, or can be considered trespassing or invasion of privacy. Exploration sites Abandonments Ventures into abandoned structures are per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collapse Of The Soviet Union
The dissolution of the Soviet Union, also negatively connoted as rus, Разва́л Сове́тского Сою́за, r=Razvál Sovétskogo Soyúza, ''Ruining of the Soviet Union''. was the process of internal disintegration within the Soviet Union (USSR) which resulted in the end of the country's and its federal government's existence as a sovereign state, thereby resulting in its constituent republics gaining full sovereignty on 26 December 1991. It brought an end to General Secretary Mikhail Gorbachev's (later also President) effort to reform the Soviet political and economic system in an attempt to stop a period of political stalemate and economic backslide. The Soviet Union had experienced internal stagnation and ethnic separatism. Although highly centralized until its final years, the country was made up of fifteen top-level republics that served as homelands for different ethnicities. By late 1991, amid a catastrophic political crisis, with several republics alre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
