Tupolev Tu-142
The Tupolev Tu-142 (russian: Туполев Ту-142; NATO reporting name: Bear F/J) is a Soviet/Russian maritime reconnaissance and anti-submarine warfare (ASW) aircraft derived from the Tu-95 turboprop strategic bomber. A specialised communications variant designated ''Tu-142MR'' was tasked with long-range communications duties with Soviet ballistic missile submarines. The Tu-142 was designed by the Tupolev design bureau, and manufactured by the Kuibyshev Aviation and Taganrog Machinery Plants from 1968 to 1994. Formerly operated by the Soviet Navy and Ukrainian Air Force, the Tu-142 currently serves with the Russian Navy. Developed in response to the American Polaris programme, the Tu-142 grew out of the need for a viable Soviet ASW platform. It succeeded the failed Tu-95PLO project, Tupolev's first attempt at modifying the Tu-95 for maritime use. The Tu-142 differed from the Tu-95 in having a stretched fuselage to accommodate specialised equipment for its ASW and survei ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Avionics
Avionics (a blend word, blend of ''aviation'' and ''electronics'') are the Electronics, electronic systems used on aircraft. Avionic systems include communications, Air navigation, navigation, the display and management of multiple systems, and the hundreds of systems that are fitted to aircraft to perform individual functions. These can be as simple as a searchlight for a police helicopter or as complicated as the tactical system for an airborne early warning platform. History The term "avionics" was coined in 1949 by Philip J. Klass, senior editor at ''Aviation Week & Space Technology'' magazine as a portmanteau of "aviation electronics". Radio communication was first used in aircraft just prior to World War I. The first Airborne radio relay, airborne radios were in zeppelins, but the military sparked development of light radio sets that could be carried by heavier-than-air craft, so that aerial reconnaissance biplanes could report their observations immediately in case ...

Sonobuoy
A sonobuoy (a portmanteau of sonar and buoy) is a relatively small buoy – typically diameter and long – expendable sonar system that is dropped/ejected from aircraft or ships conducting anti-submarine warfare or underwater acoustic research. Theory of operation Sonobuoys are ejected from aircraft in canisters and deploy upon water impact. An inflatable surface float with a radio transmitter remains on the surface for communication with the aircraft, while one or more hydrophone sensors and stabilizing equipment descend below the surface to a selected depth that is variable, depending on environmental conditions and the search pattern. The buoy relays acoustic information from its hydrophone(s) via UHF/ VHF radio to operators on board the aircraft. History With the technological improvement of the submarine in modern warfare, the need for an effective tracking system was born. Sound Navigation And Ranging (SONAR) was originally developed by the British—who cal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Government Of The Soviet Union
The Government of the Soviet Union ( rus, Прави́тельство СССР, p=prɐˈvʲitʲɪlʲstvə ɛs ɛs ɛs ˈɛr, r=Pravítelstvo SSSR, lang=no), formally the All-Union Government of the Union of Soviet Socialist Republics, commonly abbreviated to Soviet Government, was the executive and administrative organ of state in the former Soviet Union. It had four different names throughout its existence; Council of People's Commissars (1923–1946), Council of Ministers (1946–1991), Cabinet of Ministers (January – August 1991) and Committee on the Operational Management of the National Economy (August–December 1991). It also was known as Workers-Peasants Government of the Soviet Union. The government was led by a chairman, most commonly referred to as " premier" by outside observers. The chairman was nominated by the Central Committee of the Communist Party of the Soviet Union (CPSU) and elected by delegates at the first plenary session of a newly elected Supreme Sovi ...

Charleston, South Carolina
Charleston is the largest city in the U.S. state of South Carolina, the county seat of Charleston County, and the principal city in the Charleston–North Charleston metropolitan area. The city lies just south of the geographical midpoint of South Carolina's coastline on Charleston Harbor, an inlet of the Atlantic Ocean formed by the confluence of the Ashley, Cooper, and Wando rivers. Charleston had a population of 150,277 at the 2020 census. The 2020 population of the Charleston metropolitan area, comprising Berkeley, Charleston, and Dorchester counties, was 799,636 residents, the third-largest in the state and the 74th-largest metropolitan statistical area in the United States. Charleston was founded in 1670 as Charles Town, honoring King CharlesII, at Albemarle Point on the west bank of the Ashley River (now Charles Towne Landing) but relocated in 1680 to its present site, which became the fifth-largest city in North America within ten years. It remained unincorpor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS George Washington (SSBN-598)
USS ''George Washington'' (SSBN-598) was the United States's first operational ballistic missile submarine. She was the lead ship of her class of nuclear ballistic missile submarines, was the third United States Navy ship of the name, in honor of Founding Father George Washington (1732–1799), the first president of the United States, and was the first of that name to be purpose-built as a warship. Construction and launching ''George Washingtons keel was laid down at Electric Boat Division of General Dynamics, Groton, Connecticut on 1 November 1958. The first of her class, she was launched on 9 June 1959 sponsored by Mrs. Ollie Mae Anderson (née Rawlins), wife of US Treasury Secretary and former Secretary of the Navy Robert B. Anderson, and commissioned on 30 December 1959 as SSBN-598 with Commander James B. Osborn in command of the Blue crew and Commander John L. From, Jr. in command of the Gold crew.

Ballistic Missile
A ballistic missile is a type of missile that uses projectile motion to deliver warheads on a target. These weapons are guided only during relatively brief periods—most of the flight is unpowered. Short-range ballistic missiles stay within the Earth's atmosphere, while intercontinental ballistic missiles (ICBMs) are launched on a sub-orbital flight. These weapons are in a distinct category from cruise missiles, which are aerodynamically guided in powered flight. Unlike cruise missiles, which are restricted to the atmosphere, it is advantageous for ballistic missiles to avoid the denser parts of the atmosphere and they may travel above the atmosphere into outer space. History The earliest form of ballistic missile dates from the 13th century with its use derived from the history of rockets. In the 14th century, the Ming Chinese navy used an early form of a ballistic missile weapon called the Huolongchushui in naval battles against enemy ships.Needham, Volume 5, Part 7, ...

Booster (rocketry)
A booster rocket (or engine) is either the first stage of a multistage launch vehicle, or else a shorter-burning rocket used in parallel with longer-burning sustainer rockets to augment the space vehicle's takeoff thrust and payload capability. Boosters are traditionally necessary to launch spacecraft into low Earth orbit (absent a single-stage-to-orbit design), and are especially important for a space vehicle to go beyond Earth orbit. The booster is dropped to fall back to Earth once its fuel is expended, a point known as ''booster engine cut-off'' (BECO). Following booster separation, the rest of the launch vehicle continues flight with its core or upper-stage engines. The booster may be recovered, refurbished and reused, as was the case of the steel casings used for the Space Shuttle Solid Rocket Boosters. Drop-away engines The SM-65 Atlas rocket used three engines, one of which was fixed to the fuel tank, and two of which were mounted on a skirt which dropped away at BECO ...

Submarine-launched Ballistic Missile
A submarine-launched ballistic missile (SLBM) is a ballistic missile capable of being launched from submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs), each of which carries a nuclear warhead and allows a single launched missile to strike several targets. Submarine-launched ballistic missiles operate in a different way from submarine-launched cruise missiles. Modern submarine-launched ballistic missiles are closely related to intercontinental ballistic missiles (ICBMs), with ranges of over , and in many cases SLBMs and ICBMs may be part of the same family of weapons. History Origins The first practical design of a submarine-based launch platform was developed by the Germans near the end of World War II involving a launch tube which contained a V-2 ballistic missile variant and was towed behind a submarine, known by the code-name ''Prüfstand XII''. The war ended before it could be tested, but the engineers who had worked o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tu-142M-1986-DN-SC-87-03779-front
The Tupolev Tu-14 (NATO reporting name: Bosun) (USAF/USDOD, DOD reporting name: Type 35), was a Soviet Union, Soviet twinjet light bomber derived from the Tupolev Tu-73, the failed competitor to the Ilyushin Il-28, Ilyushin Il-28 'Beagle'. It was used as a torpedo bomber by the mine-torpedo regiments of Soviet Naval Aviation between 1952–59 and exported to the People's Republic of China. Development The Tu-14 had its origin in the three-engined '73' design which used a pair of Rolls-Royce Nene turbojets under the wings and a single Rolls-Royce Derwent V in the tail, in an installation much like that of the central engine of a Boeing 727. The availability of the Klimov VK-1, a more-powerful version of the Nene, allowed the RD-500 to be deleted from the preliminary design, which was given the internal designation of "81". The other major change was the addition of a PSBN navigation radar which required a fifth crewmember to operate. This was rejected by the Soviet Air Forces, ...
