Volga Radar
Baranavichy Radar Station () (sometimes wrongly named GantsavichyThe names vary as the station may be wrongly named after the nearby town of Hantsavichy, but with different transliterations depending on whether we consider the name to be Russian or Belarusian. The character Г is a G in Russian and an H in Belarusian. Using the BGN/PCGN Romanisation standard the Belarusian name Га́нцавічы would be written as Hantsavichy and using Wikipedia's Russian Romanisation standard the Russian name Ганцевичи would be written as Gantsevichi) is a 70M6 Volga-type radar near Hantsavichy in Belarus (48 km from Baranavichy). It is an early warning radar, which is run by the Russian Space Forces. It is designed to identify launches of ballistic missiles from western Europe and can also track some artificial satellites, partly replacing the demolished radar station at Skrunda in Latvia. History The Volga was developed by NIIDAR from the Dunay-3U radar. Construction sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Union
The Union of Soviet Socialist Republics. (USSR), commonly known as the Soviet Union, was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 until Dissolution of the Soviet Union, it dissolved in 1991. During its existence, it was the list of countries and dependencies by area, largest country by area, extending across Time in Russia, eleven time zones and sharing Geography of the Soviet Union#Borders and neighbors, borders with twelve countries, and the List of countries and dependencies by population, third-most populous country. An overall successor to the Russian Empire, it was nominally organized as a federal union of Republics of the Soviet Union, national republics, the largest and most populous of which was the Russian SFSR. In practice, Government of the Soviet Union, its government and Economy of the Soviet Union, economy were Soviet-type economic planning, highly centralized. As a one-party state go ...

Intermediate-Range Nuclear Forces Treaty
The Intermediate-Range Nuclear Forces Treaty (INF Treaty) was an arms control treaty between the United States and the Soviet Union (and its successor state, the Russia, Russian Federation). President of the United States, US President Ronald Reagan and General Secretary of the Communist Party of the Soviet Union, Soviet General Secretary Mikhail Gorbachev signed the treaty on 8 December 1987. The United States Senate, US Senate approved the treaty on 27 May 1988, and Reagan and Gorbachev ratified it on 1 June 1988. The INF Treaty banned all of the two nations' nuclear and conventional ground-launched ballistic missiles, cruise missiles, and missile launchers with ranges of ("intermediate-range") and ("shorter-range"). The treaty did not apply to air- or sea-launched missiles. By May 1991, the nations had eliminated 2,692 missiles, followed by 10 years of on-site verification inspections. President Donald Trump announced on 20 October 2018 that he was withdrawing the US from th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Electronically Scanned Array
An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna. In the AESA, each antenna element is connected to a small solid-state transmit/receive module (TRM) under the control of a computer, which performs the functions of a transmitter and/or receiver for the antenna. This contrasts with a passive electronically scanned array (PESA), in which all the antenna elements are connected to a single transmitter and/or receiver through phase shifters under the control of the computer. AESA's main use is in radar, and these are known as active phased-array radar (APAR). The AESA is a more advanced, sophisticated, second-generation of the original PESA phased-array technology. PESAs can only emit a single beam of radio waves at a single frequency at a time. The PESA must utilize a Butler matri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altai Krai
Altai Krai (, ) is a federal subject of Russia (a krai). It borders, clockwise from the west, Kazakhstan ( East Kazakhstan Region, Abai Region and Pavlodar Region), Novosibirsk and Kemerovo, and the Altai Republic. The krai's administrative centre is the city of Barnaul. As of the 2021 Census, the population of the krai was 2,163,693. Name The region is named after the Altai Mountains. History Bone fragments of the Denisova hominin originate from the Denisova Cave in Altai Krai. This area is part of a great crossroads in the ancient world. Nomadic tribes crossed through the territory during periods of migration. These nomadic tribes consisted of different peoples. Archeological sites reveal that ancient humans lived in the area. The Altay people are a Turkic people, some of whom settled here, who were originally nomadic and date back to the 2nd millennium BC. The territory of the krai has been controlled by the Xiongnu Empire (209 BC–93 AD), the Rouran Khaganate (33 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biysk
Biysk ( rus, Бийск, p=bʲijsk; , ) is a city in Altai Krai, Russia, located on the Biya River not far from its confluence with the Katun River. It is the second largest city of the krai (after Barnaul, the administrative center of the krai). Population: History The fortress of Bikatunskaya (), or Bikatunsky Ostrog (), was founded in 1708-1709: it was constructed near the confluence of Biya and Katun Rivers (hence the name) in 1709 by the order the Russian Tsar Peter the Great signed in 1708. Yet, in 1710, after a three-day battle, the ostrog was destroyed by the Dzungar people. The Bikatunskaya fortress was re-built at a new place ( up the Biya, on the right bank of the river) in 1718 and renamed Biyskaya () in 1732. Gradually, Biysk lost its role as a military base, but became an important center of trade, and was granted town status in 1782. In 1797, the town was abolished, but in 1804 it was restored as an uyezd town of Tomsk Governorate and granted the coat of arms ...

Komsomolsk-na-Amur
Komsomolsk-on-Amur ( rus, Комсомольск-на-Амуре, r=Komsomolsk-na-Amure, p=kəmsɐˈmolʲsk nɐ‿ɐˈmurʲə) is a city in Khabarovsk Krai, Russia, located on the west bank of the Amur River in the Russian Far East. It is located on the Baikal-Amur Mainline, northeast of Khabarovsk. Population: History The future site of Komsomolsk-on-Amur was conquered by the Mongols in the 13th century, becoming part of the Yuan dynasty. It was later held by the Qing dynasty until the area was ceded to the Russian Empire in the treaty of Aigun in 1858. The village of Permskoye () was established on the later site of Komsomolsk in 1860 by migrant peasants from what was then called the Nizhne-Tambovsky District, Far Eastern Territory (now Khabarovsk Krai). The government of the Russian SFSR announced in 1931 plans to construct a shipyard on the Amur at the present site of Komsomolsk, with construction beginning in 1932. According to official mythology, the town was built ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dnestr Radar
Dnestr radar () and Dnepr radar (), both known by the NATO reporting name Hen House, are the first generation of Soviet space surveillance and early warning radars. Six radars of this type were built on the periphery of the Soviet Union starting in the 1960s to provide ballistic missile warnings for attacks from different directions. They were the primary Soviet early warning radars for much of the later Cold War. In common with other Soviet and Russian early warning radars they are named after rivers, the Dnestr and the Dnepr. The Dnestr/Dnepr radars were intended to be replaced by the newer Daryal radars starting in the 1990s. Only two of the planned Daryal radars became operational, due to issues such as the dissolution of the Soviet Union. As of 2012, the Russian early warning network still consists of some radars of this vintage. It is likely that all the existing radars will be replaced by the third generation Voronezh radars by 2020. TsSO-P The Dnestr radar came fro ...

Dissolution Of The Soviet Union
The Soviet Union was formally dissolved as a sovereign state and subject of international law on 26 December 1991 by Declaration No. 142-N of the Soviet of the Republics of the Supreme Soviet of the Soviet Union. Declaration No. 142-Н of the Soviet of the Republics of the Supreme Soviet of the Soviet Union, formally establishing the dissolution of the Soviet Union as a state and subject of international law. It also brought an end to the Soviet Union's federal government and General Secretary (also President) Mikhail Gorbachev's 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 15 top-level republics that served as the homelands for different ethnicities. By late 1991, amid a catastrophic political crisis, with several republics al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yeniseysk-15
Yeniseysk-15 was the site of a disputed Soviet phased array radar near Yeniseysk in Krasnoyarsk Krai, Siberia. The never operational Daryal radar installation was demolished in 1989 after the United States claimed it was in breach of the Anti-Ballistic Missile Treaty. Daryal radar The radar being built at Yeniseysk was a Daryal-U (NATO codename "Pechora"), a large phased array radar consisting of two separate large phased-array antennas apart. The transmitter array was and the receiver was in size. The system is a VHF system operating at a wavelength of 1.5 to 2 meters (150 to 200 MHz). The claimed range of a Daryal installation is . Originally, at least seven Daryal facilities were planned, however, only the first two facilities completed, Pechora and Gabala, were ever operational. Two other Daryal-U type were to be built at Balkhash and Mishelevka, Irkutsk, neither were completed before the collapse of the Soviet Union. Location The Soviet Union started a program ...

Daryal Radar
The Daryal-type radar () (NATO: Pechora) is a Soviet bistatic early-warning radar. It consists of two separate large active phased-array antennas separated by around to . The transmitter array is and the receiver is in size. The system is a VHF system operating at a wavelength of 1.5 to 2 meters (150 to 200 MHz). Its initial transmit capacity was 50 MW with a target capacity of 350 MW. The designer of the radars, RTI Mints, says that each Daryal receiver is 100 × 100m and has 4,000 cross dipoles. Each transmitter is 40 × 40m with 1,260 modules, each capable of 300 kW. They say the radar has a range of 6,000 km with targets between 0.1 and 0.12m. It can track 20 objects at the same time and can cope with four jamming sources. The designer, Viktor Ivantsov, was awarded the title "Hero of Labour" for his work on the Daryal. The first Daryal type radar was an active electronically scanned array built at Olenegorsk in 1977. It was the receiver building only an ...
