Verkhoturye
Verkhoturye (russian: Верхоту́рье) is a historical town and the administrative center of Verkhotursky District of Sverdlovsk Oblast, Russia, located in the middle Ural Mountains on the left bank of the Tura River north of Yekaterinburg. Population: 7,815 ( 2002 Census; 10,900 (1967). History Verkhoturye was founded in 1598 by Vasily Golovin and Ivan Voyeykov on the site of the Vogul settlement of Neromkar. There were major fires in 1674 and 1738. The railroad arrived in 1906. It lost town status in 1926 and regained it in 1947. Two oil pipelines pass through the area and there are plans to build an oil refinery. In contrast to the surrounding mining towns, Verkhoturye has been relatively untouched by industrialization and much of its historic appearance has been preserved. Being one of the oldest Russian settlements east of the Urals, and with forty churches in the area, Verkhoturye is considered one of the centers of Russian Christianity. Famous churches include ...

Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cor ...

Submarines Of Russia
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navy, navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, Blockade runner, blockade running, Ballistic missile submarine, nuclear deterrence, reconnaissance, conventio ...

Cold War Submarines 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 ...

Ships Built In The Soviet Union
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were cont ...

R-29RM
The R-29RM Shtil (Russian: Штиль, lit. ''"Calmness"'', NATO reporting name SS-N-23 Skiff) was a liquid propellant, submarine-launched ballistic missile in use by the Russian Navy. It had the alternate Russian designations RSM-54 and GRAU index 3M27. It was designed to be launched from the Delta IV submarine, each of which is capable of carrying 16 missiles. The R-29RM could carry four 100 kiloton warheads and had a range of about . They were replaced with the newer R-29RMU2 Sineva and later with the enhanced variant R-29RMU2.1 Layner. History Development Development of the R-29RM started in 1979 at the Makeyev Rocket Design Bureau. The navy accepted the armament in 1986 and subsequently installed the D-9RM launch system consisting of a cluster of 16 R-29RM onboard the nuclear-propelled Project 667BDRM submarines. Operation Behemoth On 6 August 1991 at 21:09, K-407 , under the command of Captain Second Rank Sergey Yegorov, became the world's only submarine to su ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
26th Congress Of The CPSU
The 26th Congress of the Communist Party of the Soviet Union (''26th Congress of the CPSU'', rus, XXVI съезд КПСС) opened on February 23, 1981, with a five-hour address by the General Secretary of the Communist Party and the chairman (president) of the Presidium of the Supreme Soviet Leonid Brezhnev. This was the last Congress for Brezhnev, who died in 1982. Brezhnev proposed another round of arms control talks. At a time when an aging Soviet leadership faced a decline in economic growth, severe food problems at home, grave uncertainties about its future relationship with the United States, and unsettling events in Poland, the congress ended its week of speeches by unanimously confirming the existing leadership. The congress elected the 26th Central Committee. The 1st Plenary Session of the 26th Central Committee elected the 26th Politburo. The members of the 26th Politburo were all members of the 25th Politburo. The 14 voting members, whose average age was 69, and ...

SLBM
A submarine-launched ballistic missile (SLBM) is a ballistic missile capable of being launched from Ballistic missile submarine, submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs), each of which carries a thermonuclear weapon, 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 rocket, V-2 ballistic missile variant and was towed behind a submarine, known by the code-name V-2 rocket#Unfulfilled plans, ''Prüf ...

Draft (ship)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
