HMS Rainbow (1747)
Nine ships of the Royal Navy have been named HMS ''Rainbow'', after the rainbow, a common meteorological phenomenon: * was a 26-gun galleon launched in 1586. She was rebuilt in 1602, and again in 1617 to carry 40 guns. She was reconstructed about 1630 as a second rate of 54 guns. She was sunk as a breakwater in 1680. * was a 32-gun fifth rate captured from the French in 1697 and sold in 1698. * was a 44-gun fifth rate launched in 1747. She was used as a troopship from 1776, then equipped experimentally with carronades she captured the off the coast of Brittany in 1782, was on harbour service from 1784 and was sold in 1802. * was a 16-gun brig-sloop captured from the French in 1806 and sold in 1807. * was a 28-gun sixth rate, previously the French ship ''Iris''. She was captured in 1809 by and was sold in 1815. * was a 28-gun sixth rate launched in 1823 and sold in 1838. * was an wood screw gunboat launched in 1856. She was used as a survey vessel from 1857, and a trainin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Rainbow
A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the Sun. Rainbows can be full circles. However, the observer normally sees only an arc formed by illuminated droplets above the ground, and centered on a line from the Sun to the observer's eye. In a primary rainbow, the arc shows red on the outer part and violet on the inner side. This rainbow is caused by light being refracted when entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it. In a double rainbow, a second arc is seen outside the primary arc, and has the order of its colours reversed, with red on the inner side of the arc. This is caused by the light being reflected twice on the inside of the drop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galleon
Galleons were large, multi-decked sailing ships first used as armed cargo carriers by European states from the 16th to 18th centuries during the age of sail and were the principal vessels drafted for use as warships until the Anglo-Dutch Wars of the mid-1600s. Galleons generally carried three or more masts with a lateen fore-and-aft rig on the rear masts, were carvel built with a prominent squared off raised stern, and used square-rigged sail plans on their fore-mast and main-masts. Such ships were the mainstay of maritime commerce into the early 19th century, and were often drafted into use as auxiliary naval war vessels—indeed, were the mainstay of contending fleets through most of the 150 years of the Age of Exploration—before the Anglo-Dutch wars brought purpose-built ship-rigged warships, ships of the line, that thereafter dominated war at sea during the remainder of the age of sail. Etymology The word ''galleon'' 'large ship' comes from Old French ''galion'' 'arme ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breakwater (structure)
A breakwater is a permanent structure constructed at a coastal area to protect against tides, currents, waves, and storm surges. Part of a coastal management system, breakwaters are installed to minimize erosion, and to protect anchorages, helping isolate vessels within them from marine hazards such as prop washes and wind-driven waves. A breakwater, also known in some contexts as a jetty, may be connected to land or freestanding, and may contain a walkway or road for vehicle access. On beaches where longshore drift threatens the erosion of beach material, smaller structures on the beach, usually perpendicular to the water's edge, may be installed. Their action on waves and current is intended to slow the longshore drift and discourage mobilisation of beach material. In this usage they are more usually referred to as groynes. Purposes Breakwaters reduce the intensity of wave action in inshore waters and thereby provide safe harbourage. Breakwaters may also be small structu ...

Fifth Rate
In the rating system of the Royal Navy used to categorise sailing warships, a fifth rate was the second-smallest class of warships in a hierarchical system of six " ratings" based on size and firepower. Rating The rating system in the Royal Navy as originally devised had just four rates, but early in the reign of Charles I, the original fourth rate (derived from the "Small Ships" category under his father, James I) was divided into new classifications of fourth, fifth, and sixth rates. While a fourth-rate ship was defined as a ship of the line, fifth and the smaller sixth-rate ships were never included among ships-of-the-line. Nevertheless, during the Anglo-Dutch Wars of the 17th century, fifth rates often found themselves involved among the battle fleet in major actions. Structurally, these were two-deckers, with a complete battery on the lower deck, and fewer guns on the upper deck (below the forecastle and quarter decks, usually with no guns in the waist on this deck). The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Troopship
A troopship (also troop ship or troop transport or trooper) is a ship used to carry soldiers, either in peacetime or wartime. Troopships were often drafted from commercial shipping fleets, and were unable land troops directly on shore, typically loading and unloading at a seaport or onto smaller vessels, either tenders or barges. Attack transports, a variant of ocean-going troopship adapted to transporting invasion forces ashore, carry their own fleet of landing craft. Landing ships beach themselves and bring their troops directly ashore. History Ships to transport troops were used in Antiquity. Ancient Rome used the navis lusoria, a small vessel powered by rowers and sail, to move soldiers on the Rhine and Danube. The modern troopship has as long a history as passenger ships do, as most maritime nations enlisted their support in military operations (either by leasing the vessels or by impressing them into service) when their normal naval forces were deemed insufficient fo ...

Carronade
A carronade is a short, smoothbore, cast-iron cannon which was used by the Royal Navy. It was first produced by the Carron Company, an ironworks in Falkirk, Scotland, and was used from the mid-18th century to the mid-19th century. Its main function was to serve as a powerful, short-range, anti-ship and anti-crew weapon. The technology behind the carronade was greater dimensional precision, with the shot fitting more closely in the barrel thus transmitting more of the propellant charge's energy to the projectile, allowing a lighter gun using less gunpowder to be effective. Carronades were initially found to be very successful, but they eventually disappeared as naval artillery advanced, with the introduction of rifling and consequent change in the shape of the projectile, exploding shells replacing solid shot, and naval engagements being fought at longer ranges. History The carronade was designed as a short-range naval weapon with a low muzzle velocity for merchant ships, b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brig-sloop
In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term ''sloop-of-war'' encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions. In World War I and World War II, the Royal Navy reused the term "sloop" for specialised convoy-defence vessels, including the of World War I and the highly successful of World War II, with anti-aircraft and anti-submarine capability. They performed similar duties to the American destroyer escort class ships, and also performed similar duties to the smaller corvettes of the Royal Navy. Rigging A sloop-of-war was quite different from a civilian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sixth Rate
In the rating system of the Royal Navy used to categorise sailing warships, a sixth-rate was the designation for small warships mounting between 20 and 28 carriage-mounted guns on a single deck, sometimes with smaller guns on the upper works and sometimes without. It thus encompassed ships with up to 30 guns in all. In the first half of the 18th century the main battery guns were 6-pounders, but by mid-century these were supplanted by 9-pounders. 28-gun sixth rates were classed as frigates, those smaller as 'post ships', indicating that they were still commanded by a full ('post') captain, as opposed to sloops of 18 guns and less under commanders. Rating Sixth-rate ships typically had a crew of about 150–240 men, and measured between 450 and 550 tons. A 28-gun ship would have about 19 officers; commissioned officers would include the captain, and two lieutenants; warrant officers would include the master, ship's surgeon, and purser. The other quarterdeck officers were the c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Survey Vessel
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 ...

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. Notable training ships Royal Navy * * * * * * * ''Cornwall'' * * * * * * '' Indefatigable'' * , including adjacent * * * * ''Mount Edgcumbe'' * * * '' Warspite'' (1877) * '' Warspite'' (1922) * * '' Wellesley'' * Other navies * Algerian Navy ** '' El-Mellah'' * Argentine Navy ** ** * Bangladesh Navy ** BNS ''Shaheed Ruhul Amin'' * Brazilian Navy ** ''Cisne Branco'' * Bulgarian Navy ** * Royal Canadian Navy ** (sail training) ** HMCS ...
