Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USS Wasp (1814)
USS ''Wasp'' was a sloop-of-war that served in the United States Navy in 1814 during the War of 1812. She was the fifth United States Navy ship to carry that name. She carried out two successful raiding voyages against British trade during the summer of 1814, in the course of which she fought and defeated three British warships. ''Wasp'' was lost, cause unknown, in the Atlantic in early autumn, 1814. Service history ''Wasp'' was a ship-rigged sloop-of-war constructed in 1813 at Newburyport, Massachusetts, by Cross & Merrill. She was commissioned in February of 1814, with Master Commandant Johnston Blakeley in command. She remained at Portsmouth, New Hampshire, until late spring awaiting sailing orders and, upon receipt of them, put to sea on 1 May 1814 for a war cruise to the western approaches to the English Channel. First raiding voyage ''Wasp'' captured her first vessel, the 207-ton barque ''Neptune'', on 2 June 1814, embarked her crew as prisoners, and burned the prize ...

Paddle Steamer
A paddle steamer is a steamship or steamboat powered by a steam engine that drives paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, where the first uses were wheelers driven by animals or humans. In the early 19th century, paddle wheels were the predominant way of propulsion for steam-powered boats. In the late 19th century, paddle propulsion was largely superseded by the screw propeller and other marine propulsion systems that have a higher efficiency, especially in rough or open water. Paddle wheels continue to be used by small, pedal-powered paddle boats and by some ships that operate tourist voyages. The latter are often powered by diesel engines. Paddle wheels The paddle wheel is a large steel framework wheel. The outer edge of the wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under water. An e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Survey Ship
A survey vessel is any type of ship or boat that is used for underwater surveys, usually to collect data for mapping or planning underwater construction or mineral extraction. It is a type of research vessel, and may be designed for the purpose, modified for the purpose or temporarily put into the service as a vessel of opportunity, and may be crewed, remotely operated, or autonomous. The size and equipment vary to suit the task and availability. Role The task of survey vessels is to map the bottom, and measure the characteristics of the benthic zone, full water column, and surface for the purpose of: * hydrography, the measurement and description of the physical features of oceans and other natural bodies of water, and the prediction of their change over time, for the primary purpose of safety of navigation and in support of other activities associated with those bodies of water, * general oceanography, the scientific study of the oceans, * mapping of marine habitats as part ...

Gunboat
A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies. History Pre-steam era In the age of sail, a gunboat was usually a small undecked vessel carrying a single smoothbore cannon in the bow, or just two or three such cannons. A gunboat could carry one or two masts or be oar-powered only, but the single-masted version of about length was most typical. Some types of gunboats carried two cannons, or else mounted a number of swivel guns on the railings. The small gunboat had advantages: if it only carried a single cannon, the boat could manoeuvre in shallow or restricted areas – such as rivers or lakes – where larger ships could sail only with difficulty. The gun that such boats carried could be quite heavy; a 32-pounder for instance. As such boats were cheap and quick to build, naval forces favoured swarm ...

New Zealand Wars
The New Zealand Wars took place from 1845 to 1872 between the New Zealand colonial government and allied Māori on one side and Māori and Māori-allied settlers on the other. They were previously commonly referred to as the Land Wars or the Māori Wars, while Māori language names for the conflicts included ("the great New Zealand wars") and ("the white man's anger"). Historian James Belich popularised the name "New Zealand Wars" in the 1980s, although according to Vincent O'Malley, the term was first used by historian James Cowan in the 1920s. Though the wars were initially localised conflicts triggered by tensions over disputed land purchases, they escalated dramatically from 1860 as the government became convinced it was facing united Māori resistance to further land sales and a refusal to acknowledge Crown sovereignty. The colonial government summoned thousands of British troops to mount major campaigns to overpower the Kīngitanga (Māori King) movement and also con ...

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Destroyer
In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish NavySmith, Charles Edgar: ''A short history of naval and marine engineering.'' Babcock & Wilcox, ltd. at the University Press, 1937, page 263 as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War. Before World War II, destroyers were light vessels with little endurance for unattended o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portuguese Navy
The Portuguese Navy ( pt, Marinha Portuguesa, also known as ''Marinha de Guerra Portuguesa'' or as ''Armada Portuguesa'') is the naval branch of the Portuguese Armed Forces which, in cooperation and integrated with the other branches of the Portuguese military, is charged with the military defense of Portugal. On 12 December 2017, the Portuguese Navy commemorated the 700th anniversary of its official creation by King Denis of Portugal. Tracing its origins back to the 12th century, it is the oldest continuously serving navy in the world. The Navy played a key role at the beginning and during the great voyages of the Age of Discoveries in the 15th and 16th centuries. The result of this technical and scientific discoveries led Portugal to develop advanced ships, including the caravel, new and more sophisticated types of carracks for interoceanic travel and the oceanic galleon, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
