Russian Destroyer Gavril
''Gavriil'' (Russian: ''Гавриил'') was an of the Russian Imperial Navy. The destroyer was built by the Russo-Baltic Yard at Reval (now Tallinn in Estonia), launching on 5 January 1915 and completing in October 1916. She served with the Baltic Fleet during the remainder of the First World War, and after the October Revolution joined the Bolshevik Red Fleet. She was active during the Russian Civil War, taking part in several engagements against British ships during the British campaign in the Baltic, and was sunk by a mine on 21 October 1919. Design and construction In 1912, the Russian State Duma passed a shipbuilding programme for the Imperial Russian Navy that envisioned the construction of four battlecruisers, eight cruisers, 36 destroyers and 18 submarines, mainly for the Baltic Fleet. To meet this requirement, the Putilov Yard of Saint Petersburg proposed a modified version of the , to be built by Putilov, the Metal Works of Saint Petersburg, and the Russo-Baltic Yar ...

Russian Empire
The Russian Empire was an empire that spanned most of northern Eurasia from its establishment in November 1721 until the proclamation of the Russian Republic in September 1917. At its height in the late 19th century, it covered about , roughly one-sixth of the world's landmass, making it the list of largest empires, third-largest empire in history, behind only the British Empire, British and Mongol Empire, Mongol empires. It also Russian colonization of North America, colonized Alaska between 1799 and 1867. The empire's 1897 census, the only one it conducted, found a population of 125.6 million with considerable ethnic, linguistic, religious, and socioeconomic diversity. From the 10th to 17th centuries, the Russians had been ruled by a noble class known as the boyars, above whom was the tsar, an absolute monarch. The groundwork of the Russian Empire was laid by Ivan III (), who greatly expanded his domain, established a centralized Russian national state, and secured inde ...

Soviet Navy
The Soviet Navy was the naval warfare Military, uniform service branch of the Soviet Armed Forces. Often referred to as the Red Fleet, the Soviet Navy made up a large part of the Soviet Union's strategic planning in the event of a conflict with the opposing superpower, the United States, during the Cold War (1945–1991). The Soviet Navy played a large role during the Cold War, either confronting the North Atlantic Treaty Organization in western Europe or power projection to maintain its Warsaw Pact, sphere of influence in eastern Europe. The Soviet Navy was divided into four major fleets: the Soviet Northern Fleet, Northern, Pacific Fleet (Russia), Pacific, Black Sea Fleet, Black Sea, and Baltic Fleet, Baltic Fleets, in addition to the Leningrad Naval Base, which was commanded separately. It also had a smaller force, the Caspian Flotilla, which operated in the Caspian Sea and was followed by a larger fleet, the 5th Operational Squadron, 5th Squadron, in the Mediterranean Sea. The ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a shipbuilding, 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 a ship's life; the others are Ceremonial ship launching, launching, Ship commissioning, commissioning, and Ship decommissioning, decommissioning. Earlier, 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 ...

AEG (German Company)
; AEG) was a German producer of electrical equipment. It was established in 1883 by Emil Rathenau as the ''Deutsche Edison-Gesellschaft für angewandte Elektricität'' in Berlin. The company's initial focus was driven by electrical lighting, as in 1881, Rathenau had acquired the rights to the electric light bulb at the International Exposition of Electricity in Paris. Using small power stations, his company introduced electrical lighting to cafés, restaurants, and theaters, despite the high costs and limitations. By the end of the 19th century, AEG had constructed 248 power stations, providing a total of 210,000 hp of electricity for lighting, tramways, and household devices. During the World War II, Second World War, AEG worked with the Nazi Party and benefited from forced labour from concentration camps. After the war, its headquarters moved to Frankfurt am Main. In 1967, AEG joined with its subsidiary Telefunken, Telefunken AG, creating ''Allgemeine Elektricitäts-Ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p. 5. This is accomplished by means of its "draft marks". A merchant vessel has t ...

Draft (ship)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if depl ...

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 sides 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 cora ...

Imperial Russian Navy
The Imperial Russian Navy () operated as the navy of the Russian Tsardom and later the Russian Empire from 1696 to 1917. Formally established in 1696, it lasted until being dissolved in the wake of the February Revolution and the declaration of the Russian Republic in 1917. It developed from a smaller force that had existed prior to Tsar Peter the Great's founding of the modern Russian navy during the Azov campaigns (1695–1696), Second Azov campaign in 1696, and expanded in the second half of the 18th century before reaching its peak strength by the early part of the 19th century, behind only the British and French fleets in terms of size. The Imperial Navy drew its officers from the aristocracy of the Empire, who belonged to the state Russian Orthodox Church. Young aristocrats began to be trained for leadership at a national naval boarding school, the Naval Cadet Corps (Russia), Naval Cadet Corps. From 1818 on, only officers of the Imperial Russian Navy were appointed to the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
State Duma (Russian Empire)
The State Duma, also known as the Imperial Duma, was the lower house of the legislature in the Russian Empire, while the upper house was the State Council. It held its meetings in the Tauride Palace in Saint Petersburg. It convened four times between 27 April 1906 and the collapse of the empire in February 1917. The first and the second dumas were more democratic and represented a greater number of national types than their successors. The third duma was dominated by gentry, landowners, and businessmen. The fourth duma held five sessions; it existed until 2 March 1917, and was formally dissolved on 6 October 1917. History Coming under pressure from the Russian Revolution of 1905, on August 6, 1905 (O.S.), Sergei Witte (appointed by Nicholas II to manage peace negotiations with Japan after the Russo-Japanese War of 1904–1905) issued a manifesto about the convocation of the Duma, initially thought to be a purely advisory body, the so-called Bulygin-Duma.
