Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the British Armed Forces, 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 World War II, 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 ...

Lernaean Hydra
The Lernaean Hydra or Hydra of Lerna ( grc-gre, Λερναῖα Ὕδρα, ''Lernaîa Hýdra''), more often known simply as the Hydra, is a snake, serpentine water monster in Greek mythology, Greek and Roman mythology. Its lair was the lake of Lerna in the Argolid, which was also the site of the myth of the Danaïdes. Lerna was reputed to be an entrance to the Hades, Underworld, and archaeology has established it as a sacred site older than Mycenaean civilization, Mycenaean Argos, Peloponnese, Argos. In the canonical Hydra myth, the monster is killed by Heracles (Hercules) as the second of his Labours of Hercules, Twelve Labors. According to Hesiod, the Hydra was the offspring of Typhon and Echidna (mythology), Echidna. It had poisonous breath and blood so virulent that even its scent was deadly. The Hydra possessed Polycephaly, many heads, the exact number of which varies according to the source. Later versions of the Hydra story add a Regeneration (biology), regeneration feature ...

Greek Mythology
A major branch of classical mythology, Greek mythology is the body of myths originally told by the ancient Greeks, and a genre of Ancient Greek folklore. These stories concern the origin and nature of the world, the lives and activities of deities, heroes, and mythological creatures, and the origins and significance of the ancient Greeks' own cult and ritual practices. Modern scholars study the myths to shed light on the religious and political institutions of ancient Greece, and to better understand the nature of myth-making itself. The Greek myths were initially propagated in an oral-poetic tradition most likely by Minoan and Mycenaean singers starting in the 18th century BC; eventually the myths of the heroes of the Trojan War and its aftermath became part of the oral tradition of Homer's epic poems, the '' Iliad'' and the '' Odyssey''. Two poems by Homer's near contemporary Hesiod, the '' Theogony'' and the '' Works and Days'', contain accounts of the genes ...

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 w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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) ...

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 ...

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 p ...

Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turret Ship
Turret ships were a 19th-century type of warship, the earliest to have their guns mounted in a revolving gun turret, instead of a broadside arrangement. Background Before the development of large-calibre, long-range guns in the mid-19th century, the classic ship of the line design used rows of port-mounted guns on each side of the ship, often mounted in casemates. Firepower was provided by a large number of guns which could only be aimed in a limited arc from one side of the ship. Due to instability, fewer larger and heavier guns can be carried on a ship. Also, the casemates often sat near the waterline, which made them vulnerable to flooding and restricted their use to calm seas. Turrets were weapon mounts designed to protect the crew and mechanism of the artillery piece and with the capability of being aimed and fired in many directions as a rotating weapon platform. This platform can be mounted on a fortified building or structure such as an anti-naval land battery, or on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Mine
A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry vs. anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered. Although international law requires signatory nations to declare mined areas, precise locations remain secret; and non-complying individuals ...

Battle Of Dogger Bank (1915)
The Battle of Dogger Bank was a naval engagement during the First World War that took place on 24 January 1915 near the Dogger Bank in the North Sea, between squadrons of the British Grand Fleet and the (High Seas Fleet). The British had intercepted and decoded German wireless transmissions, gaining advance knowledge that a German raiding squadron was heading for Dogger Bank and ships of the Grand Fleet sailed to intercept the raiders. The British surprised the smaller and slower German squadron, which fled for home. During a stern chase lasting several hours, the British caught up with the Germans and engaged them with long-range gunfire. The British disabled , the rearmost German ship, and the Germans put the British flagship out of action. Due to inadequate signalling, the remaining British ships stopped the pursuit to sink ''Blücher''; by the time the ship had been sunk, the rest of the German squadron had escaped. The German squadron returned to harbour, with some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
