Admiral Nakhimov-class Cruiser
The ''Admiral Nakhimov''-class cruisers were a group of four light cruisers built for the Imperial Russian Navy just before World War I began in 1914. Construction was interrupted by the Russian Revolution and only two of the ships were eventually completed well after the end of the Russian Civil War by the Soviets. ''Chervona Ukraina'' was the first ship completed and was built to essentially the original design. ''Krasnyi Kavkaz'' was much modified and completed five years after ''Chervona Ukraina''. Both ships participated in the Sieges of Odessa and Sevastopol after the Germans invaded Russia in June 1941. They ferried troops into the cities, evacuated wounded and bombarded the besieging German troops. ''Chervona Ukraina'' was bombed and sunk by dive bombers in November during one of these missions and ''Krasny Kavkaz'' was badly damaged by the same type of aircraft in January 1942. After her lengthy repairs were completed, the ship transported reinforcements to cities on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
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 ...

Waterline Length
A vessel's length at the waterline (abbreviated to L.W.L)Note: originally Load Waterline Length is the length of a ship or boat at the level where it sits in the water (the ''waterline''). The LWL will be shorter than the length of the boat overall (''length overall'' or LOA) as most boats have bows and stern protrusions that make the LOA greater than the LWL. As a ship becomes more loaded, it will sit lower in the water and its ambient waterline length may change; but the registered L.W.L it is measured from a default load condition. This measure is significant in determining several of a vessel's properties, such as how much water it displaces, where the bow and stern waves occur, hull speed, amount of bottom-paint needed, etc. Traditionally, a stripe called the "boot top" is painted around the hull just above the waterline. In sailing boats, longer waterline length will usually enable a greater maximum speed, because it allows greater sail area, without increasing beam or d ...

John Brown & Company
John Brown and Company of Clydebank was a Scottish Naval architecture, marine engineering and shipbuilding firm. It built many notable and world-famous ships including , , , , , and the ''Queen Elizabeth 2 (ship), Queen Elizabeth 2''. At its height, from 1900 to the 1950s, it was one of the most highly regarded, and internationally famous, shipbuilding companies in the world. However thereafter, along with other UK shipbuilders, John Brown's found it increasingly difficult to compete with the emerging shipyards in Eastern Europe and the far East. In 1968 John Brown's merged with other Clydeside shipyards to form the Upper Clyde Shipbuilders consortium, but that collapsed in 1971. The company then withdrew from shipbuilding but its engineering arm remained successful in the manufacture of industrial gas turbines. In 1986 it became a wholly owned subsidiary of Trafalgar House (company), Trafalgar House, which in 1996 was taken over by Kvaerner. The latter closed the Clydebank en ...

Hulk (ship)
A hulk is a ship that is afloat, but incapable of going to sea. Hulk may be used to describe a ship that has been launched but not completed, an abandoned wreck or shell, or to refer to an old ship that has had its rigging or internal equipment removed, retaining only its buoyant qualities. The word hulk also may be used as a verb: a ship is "hulked" to convert it to a hulk. The verb was also applied to crews of Royal Navy ships in dock, who were sent to the receiving ship for accommodation, or "hulked". Hulks have a variety of uses such as housing, prisons, salvage pontoons, gambling sites, naval training, or cargo storage. In the days of sail, many hulls served longer as hulks than they did as functional ships. Wooden ships were often hulked when the hull structure became too old and weak to withstand the stresses of sailing. More recently, ships have been hulked when they become obsolete or when they become uneconomical to operate. Sheer hulk A sheer hulk (or shear hulk) w ...

Marine Salvage
Marine salvage is the process of recovering a ship and its cargo after a shipwreck or other maritime casualty. Salvage may encompass towing, re-floating a vessel, or effecting repairs to a ship. Today, protecting the coastal environment from spillage of oil or other contaminants is a high priority. Before the invention of radio, salvage services would be given to a stricken vessel by any ship that happened to be passing by. Nowadays, most salvage is carried out by specialist salvage firms with dedicated crew and equipment. The legal significance of salvage is that a successful salvor is entitled to a reward, which is a proportion of the total value of the ship and its cargo. The amount of the award is determined subsequently at a "hearing on the merits" by a maritime court in accordance with Articles 13 and 14 of the International Salvage Convention of 1989. The common law concept of salvage was established by the English Admiralty Court, and is defined as "a voluntary succe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Training Ship
A training ship is a ship used to train students as sailors. The term is mostly used to describe ships employed by navies to train future officers. Essentially there are two types: those used for training at sea and old hulks used to house classrooms. The hands-on aspect provided by sail training has also been used as a platform for everything from semesters at sea for undergraduate oceanography and biology students, marine science and physical science for high school students, to character building for at-risk youths.

Battle Of The Caucasus
The Battle of the Caucasus is a name given to a series of Axis and Soviet operations in the Caucasus area on the Eastern Front of World War II. On 25 July 1942, German troops captured Rostov-on-Don, Russia, opening the Caucasus region of the southern Soviet Union, and the oil fields beyond at Maikop, Grozny, and ultimately Baku, to the Germans. Two days prior, Adolf Hitler issued a directive to launch such an operation into the Caucasus region, to be named Operation Edelweiß. German forces were compelled to withdraw from the area that winter as Operation Little Saturn threatened to cut them off. Order of battle Red Army *North Caucasian Front (Marshal Semyon Budyonny) – until September 1942 *Transcaucasian Front (General of the Army Ivan Tyulenev) *Black Sea Fleet (Vice Admiral Filipp Oktyabrsky) *Azov Sea Flotilla (Rear Admiral Sergey Gorshkov) Wehrmacht Army Group A – General Field Marshal (''Generalfeldmarschall'') Wilhelm List * 1st Panzer Army- General Paul von ...

Black Sea
The Black Sea is a marginal mediterranean sea of the Atlantic Ocean lying between Europe and Asia, east of the Balkans, south of the East European Plain, west of the Caucasus, and north of Anatolia. It is bounded by Bulgaria, Georgia, Romania, Russia, Turkey, and Ukraine. The Black Sea is supplied by major rivers, principally the Danube, Dnieper, and Don. Consequently, while six countries have a coastline on the sea, its drainage basin includes parts of 24 countries in Europe. The Black Sea covers (not including the Sea of Azov), has a maximum depth of , and a volume of . Most of its coasts ascend rapidly. These rises are the Pontic Mountains to the south, bar the southwest-facing peninsulas, the Caucasus Mountains to the east, and the Crimean Mountains to the mid-north. In the west, the coast is generally small floodplains below foothills such as the Strandzha; Cape Emine, a dwindling of the east end of the Balkan Mountains; and the Dobruja Plateau considerably farth ...

Dive Bomber
A dive bomber is a bomber aircraft that dives directly at its targets in order to provide greater accuracy for the bomb it drops. Diving towards the target simplifies the bomb's trajectory and allows the pilot to keep visual contact throughout the bomb run. This allows attacks on point targets and ships, which were difficult to attack with conventional level bombers, even ''en masse''. After World War II, the rise of precision-guided munitions and improved anti-aircraft defences—both fixed gunnery positions and fighter interception—led to a fundamental change in dive bombing. New weapons, such as rockets, allowed for better accuracy from smaller dive angles and from greater distances. They could be fitted to almost any aircraft, including fighters, improving their effectiveness without the inherent vulnerabilities of dive bombers, which needed air superiority to operate effectively. Method A dive bomber dives at a steep angle, normally between 45 and 60 degrees or ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
