Symbols Of Manchester
The City of Manchester in North-West England has traditionally been represented by various symbols. Most of these symbols are derived from heraldic emblems contained within the city's official heraldic achievement, which was officially adopted when the Borough of Manchester was granted city status in 1842. Notably, the motif of the worker bee has been widely used to represent the city as a symbol of industry. Heraldry The heraldic achievement of Manchester (colloquially but inaccurately referred to as a ''coat of arms'') were granted to the Borough of Manchester in 1842 and continue to be used today by Manchester City Council. Arms: ''Gules three Bendlets enhanced Or a Chief Argent thereon on Waves of the Sea a Ship under sail proper.'' Crest: On a Wreath of the Colours a Terrestrial Globe semée of Bees volant all proper. Supporters: On the dexter side a Heraldic White Hart Argent attired collared and chain reflexed over the back Or and on the sinister side a Lion guardant Or m ...

Ticonderoga-class Cruiser
The ''Ticonderoga'' class of guided-missile cruisers is a class of warships in the United States Navy, first ordered and authorized in the 1978 fiscal year. The class uses passive electronically scanned array, passive phased-array radar and was originally planned as a class of destroyers. However, the increased combat capability offered by the Aegis Combat System and the AN/SPY-1 radar system, together with the capability of operating as a flagship, were used to justify the change of the classification from DDG (guided-missile destroyer) to CG (guided-missile cruiser) shortly before the keels were laid down for and . ''Ticonderoga''-class guided-missile cruisers are multi-role warships. Their Mark 41 Vertical Launching System, Mk 41 VLS can launch Tomahawk (missile), Tomahawk cruise missiles to strike strategic or tactical targets, or fire long-range anti-aircraft RIM-66 Standard, SM-2MR/RIM-67 Standard, ERs for defense against aircraft or anti-ship missiles.

Aegis Combat System
The Aegis Combat System is an American integrated naval weapons system developed by the Missile and Surface Radar Division of RCA, and it is now produced by Lockheed Martin. Initially used by the United States Navy, Aegis is now used also by the Japan Maritime Self-Defense Force, Spanish Navy, Royal Norwegian Navy, Republic of Korea Navy, and Royal Australian Navy, and is planned for use by the Royal Canadian Navy. As of 2022, a total of 110 Aegis-equipped ships have been deployed, and 71 more are planned (see operators). Aegis BMD (Ballistic Missile Defense) capabilities are being developed as part of the NATO missile defence system. Etymology The word "Aegis" is a reference that dates back to Greek mythology, with connotations of a protective shield, as the Aegis was the buckler (shield) of Zeus, worn by Athena. Overview The Aegis Combat System (ACS) is an advanced command and control (command and decision, or C&D, in Aegis parlance) system that uses powerful computers an ...

Iran Air Flight 655
Iran Air Flight 655 was a scheduled passenger flight from Tehran to Dubai via Bandar Abbas that was shot down on 3July 1988 by two SM-2MR surface-to-air missiles fired by the , a Cruiser#US cruiser development, guided-missile cruiser of the United States Navy. The aircraft, an Airbus A300, was destroyed and all 290 people on board were killed. The jet was hit while flying over Iran's territorial waters in the Persian Gulf, along the flight's usual route, shortly after departing Bandar Abbas International Airport, the flight's stopover location. The attack occurred during the Iran–Iraq War, which had been continuing for nearly eight years. ''Vincennes'' had entered Iranian territory after one of its helicopters drew warning fire from Iranian speedboats operating within Iranian territorial limits. The reason for the downing has been disputed between the governments of the two countries. According to the United States, U.S., the ''Vincennes'' crew had incorrectly identified the Ai ...

Margaret Thatcher
Margaret Hilda Thatcher, Baroness Thatcher (; 13 October 19258 April 2013) was Prime Minister of the United Kingdom from 1979 to 1990 and Leader of the Conservative Party (UK), Leader of the Conservative Party from 1975 to 1990. She was the first female British prime minister and the longest-serving British prime minister of the 20th century. As prime minister, she implemented economic policies that became known as Thatcherism. A Soviet journalist dubbed her the "Iron Lady", a nickname that became associated with her uncompromising politics and leadership style. Thatcher studied chemistry at Somerville College, Oxford, and worked briefly as a research chemist, before becoming a barrister. She was List of MPs elected in the 1959 United Kingdom general election, elected Member of Parliament for Finchley (UK Parliament constituency), Finchley in 1959 United Kingdom general election, 1959.

5th Destroyer Squadron (United Kingdom)
The Royal Navy 5th Destroyer Squadron was a naval unit of the Royal Navy (RN) from 1952 to 2002. History After World War II, the British Royal Navy reverted to its previous layout and command structure in February 1947; the 5th Destroyer Flotilla of the Home Fleet was reactivated, it was re-designated 5th Destroyer Squadron in January 1952, and succeeded by the 5th Destroyer Squadron. The Admiralty controlled global deployment of the Navy until 1964, when that department was abolished and replaced by the new Navy Department, within the newly formed Ministry of Defence. These geographic commands usually comprised fleets, squadrons, flotillas, and single ships. In 1954, major re-structuring of the composition of the Royal Navy was undertaken; leading to downsizing, and warships being rotated between the various fleets and stations. Between 1954 and 1971, many commands were either abolished or amalgamated into larger geographic commands. By the end of 1966, all Royal Navy sq ...

COGOG
Combined gas or gas (COGOG) is a propulsion system for ships using gas turbine engines. A high efficiency, low output turbine is used for cruising speeds with a high output turbine being used for high-speed operations. A clutch allows either turbine to be selected, but there is no gearbox to allow operation of both turbines at once. This has the advantage of not requiring heavy, expensive and potentially unreliable gearboxes. The reason that a smaller turbine is used for cruising is that a small turbine running at 100% power is more fuel efficient than a bigger turbine running at 50% power. The system is currently used in the 2 ships of the Russian Navy's s, the Japanese Maritime Self-Defense Force's Hatsuyuki-class destroyers, and the Royal Netherlands Navy s (on which the Greek Navy s are based). It was formerly used in the Royal Navy's Type 42 destroyer and Type 22 frigate, as well as the Royal Canadian Navy's ''Iroquois''-class destroyer. Development Having previously pione ...

Gas Turbine
A gas turbine, also called a combustion turbine, is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: * a rotating gas compressor * a combustor * a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel consumption (by increasing propulsive efficiency) at subsonic flight speeds. An extra turbine is also required to drive a helicopter rotor or land-vehicle transmission (turboshaft), marine propeller or electrical generator (power turbine). Greater ...

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" (or "load lines"). A mer ...

Draft (hull)
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] |
