HMCS Nootka (R96)
HMCS ''Nootka'' was a that served in the Royal Canadian Navy (RCN) from 1946 to 1964. Constructed too late to take part in the Second World War, the ship saw service in the Korean War. She received the unit name ''Nootka'' while still under construction in Halifax, Nova Scotia after the RCN renamed the to in 1943. ''Nootka'' was the second Canadian Tribal to be constructed in Canada and the second Canadian warship to circumnavigate the world. The ship was sold for scrap and broken up at Faslane, Scotland in 1965. Design The were ordered by the Canadian Naval Staff's intent to build a stronger, permanent force. The Tribals were designed to fight heavily armed destroyers of other navies, such as the Japanese . Canada chose the design based on its armament, with the size and power of the Tribal class allowing them to act more like small cruisers than as fleet destroyers. The Naval Staff intended to order the construction of a flotilla of Tribals, with two under cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuu-chah-nulth People
The Nuu-chah-nulth (; Nuučaan̓uł: ), also formerly referred to as the Nootka, Nutka, Aht, Nuuchahnulth or Tahkaht, are one of the indigenous peoples of the Pacific Northwest Coast in Canada. The term Nuu-chah-nulth is used to describe fifteen related tribes whose traditional home is on the west coast of Vancouver Island. In precontact and early post-contact times, the number of tribes was much greater, but the smallpox epidemics and other consequences of settler colonization resulted in the disappearance of some groups and the absorption of others into neighbouring groups. The Nuu-chah-nulth are related to the Kwakwaka'wakw, the Haisla, and the Ditidaht First Nation. The Nuu-chah-nulth language belongs to the Wakashan family. The governing body is the Nuu-chah-nulth Tribal Council. History Contact with Europeans When James Cook first encountered the villagers at Yuquot in 1778, they directed him to "come around" (Nuu-chah-nulth ''nuutkaa'' is "to circle around") ...

Royal Canadian Navy
The Royal Canadian Navy (RCN; french: Marine royale canadienne, ''MRC'') is the naval force of Canada. The RCN is one of three environmental commands within the Canadian Armed Forces. As of 2021, the RCN operates 12 frigates, four attack submarines, 12 coastal defence vessels, eight patrol class training vessels, two offshore patrol vessels, and several auxiliary vessels. The RCN consists of 8,570 Regular Force and 4,111 Primary Reserve sailors, supported by 3,800 civilians. Vice-Admiral Angus Topshee is the current commander of the Royal Canadian Navy and chief of the Naval Staff. Founded in 1910 as the Naval Service of Canada (French: ''Service naval du Canada'') and given royal sanction on 29 August 1911, the RCN was amalgamated with the Royal Canadian Air Force and the Canadian Army to form the unified Canadian Armed Forces in 1968, after which it was known as Maritime Command (French: ''Commandement maritime'') until 2011. In 2011, its historical title of "Royal Can ... [...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" (or "load lines"). A ...

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 a ... [...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 In watercraft, a racing shell (also referred to as just a ''fine boat'' (UK) or just ' ...

North Atlantic
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N. Scientific explorations of the Atlan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flotilla
A flotilla (from Spanish language, Spanish, meaning a small ''flota'' (Naval fleet, fleet) of ships), or naval flotilla, is a Tactical formation, formation of small warships that may be part of a larger fleet. Composition A flotilla is usually composed of a homogeneous group of the same ship class, class of warship, such as frigates, destroyers, torpedo boats, submarines, gunboats, or Minesweeper (ship), minesweepers. Groups of larger warships are usually called Squadron (naval), squadrons, but similar units of non-capital ships may be called squadrons in some instances, and flotillas in others. Formations including more than one capital ship, e.g. man-of-war, men-of-war, battleships, and aircraft carriers, typically alongside smaller ships and support craft, are typically called naval fleet, fleets, each portion led by a capital ship being a squadron or task force (see reference below). A flotilla is usually commanded by a rear admiral, a Commodore (rank), commodore or a Capt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cruiser
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several roles. The term "cruiser", which has been in use for several hundred years, has changed its meaning over time. During the Age of Sail, the term ''cruising'' referred to certain kinds of missions—independent scouting, commerce protection, or raiding—fulfilled by frigates or sloops-of-war, which functioned as the ''cruising warships'' of a fleet. In the middle of the 19th century, ''cruiser'' came to be a classification of the ships intended for cruising distant waters, for commerce raiding, and for scouting for the battle fleet. Cruisers came in a wide variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big (although not as powerful or as well-armored) as a pre-dreadnought battleship. With the advent of the dreadnought battleship before Wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commander Of The Royal Canadian Navy
The Commander of the Royal Canadian Navy ( French: ''Commandant de la Marine royale canadienne'') is the institutional head of the Royal Canadian Navy. This appointment also includes the title Chief of the Naval Staff and is based at National Defence Headquarters in Ottawa, Ontario. This individual reports to the Chief of the Defence Staff, who then responds to the Commander-in-Chief of the Canadian Armed Forces. History of the position The appointment was entitled Director of the Naval Service from 1910 to 1928 and then Chief of the Naval Staff from 1928 to 1964. In August 1964 the position of Chief of the Naval Staff was abolished. Responsibility for naval matters was split between the newly established Defence Staff in Ottawa and operational headquarters in Halifax (for Flag Officer Atlantic Coast) and Esquimalt (for Flag Officer Pacific Coast).

Faslane
His Majesty's Naval Base, Clyde (HMNB Clyde; also HMS ''Neptune''), primarily sited at Faslane on the Gare Loch, is one of three operating bases in the United Kingdom for the Royal Navy (the others being HMNB Devonport and HMNB Portsmouth). It is the navy's headquarters in Scotland and is best known as the home of Britain's nuclear weapons, in the form of nuclear submarines armed with Trident missiles. History Faslane was first constructed and used as a base in the Second World War. During the 1960s, the British Government began negotiating the Polaris Sales Agreement with the United States regarding the purchase of a Polaris missile system to fire British-built nuclear weapons from five specially constructed submarines. In the end, only four were constructed; , , and . These four submarines were permanently based at Faslane. Faslane itself was chosen to host these vessels at the height of the Cold War because of its geographic position, which forms a bastion on the re ...

Ship Breaking
Ship-breaking (also known as ship recycling, ship demolition, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships for either a source of parts Part, parts or PART may refer to: People *Armi Pärt (born 1991), Estonian handballer * Arvo Pärt (born 1935), Estonian classical composer *Brian Part (born 1962), American child actor *Dealtry Charles Part (1882–1961), sheriff (1926–1927) a ..., which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, Fatigue (material), metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycling, recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking i ...
