Ship Camouflage
Ship camouflage is a form of military deception in which a ship is painted in one or more colors in order to obscure or confuse an enemy's visual observation. Several types of marine camouflage have been used or prototyped: blending or crypsis, in which a paint scheme attempts to hide a ship from view; deception, in which a ship is made to look smaller or, as with the Q-ships, to mimic merchantmen; and dazzle, a chaotic paint scheme which tries to confuse any estimate of distance, direction, or heading. Counterillumination, to hide a darkened ship against the slightly brighter night sky, was trialled by the Royal Canadian Navy in diffused lighting camouflage. Ships were sometimes camouflaged in classical times. Mediterranean pirate ships were sometimes painted blue-gray for concealment. Vegetius records that Julius Caesar's scout ships were painted bluish-green when gathering intelligence along the coast of Britain during the Gallic Wars. Ships were sometimes painted deceptivel ...

USS West Mahomet (ID-3681) Cropped
SS ''West Mahomet'' was a steel–hull (watercraft), hulled cargo ship which saw service as an auxiliary ship, auxiliary with the U.S. Navy in 1918–19. ''West Mahomet'' was built as part of the United States Shipping Boards World War I emergency wartime shipbuilding program. Completed just too late to see service in the war, the ship was nevertheless commissioned into the Navy as USS ''West Mahomet'' (ID-3681), but saw only a handful of voyages on the Navy's behalf—including a postwar famine relief mission to Romania—before being decommissioned in June 1919. The ship was subsequently placed into merchant service as SS ''West Mahomet'', but with the onset of the Great Depression, she was laid up like many other ships of the period for lack of work. The vessel was scrapped at Rosyth, Scotland in 1938. Construction and design ''West Mahomet'' was built in Seattle, Washington in 1918 at the No. 1 Plant of the Skinner & Eddy Corporation—the 19th in a series of 24 ...

Broadside (naval)
A broadside is the side of a ship, or more specifically the artillery battery, battery of cannon on one side of a warship or their coordinated fire in naval warfare, or a measurement of a warship's maximum simultaneous firepower which can be delivered upon a single target (because this concentration is usually obtained by firing a broadside). From the 16th century until the early decades of the steamship, vessels had rows of guns set in each side of the hull (watercraft), hull. Firing all guns on one side of the ship became known as a "broadside". The cannon of 18th-century man-of-war, men of war were accurate only at short range, and their penetrating power mediocre, which meant that the thick hulls of wooden ships could only be pierced at short ranges. These wooden ships sailed closer and closer towards each other until cannon fire would be effective. Each tried to be the first to fire a broadside, often giving one party a decisive headstart in the battle when it crippled the oth ...

Jonathan Haraden
Lieutenant Jonathan Haradan (November 11, 1744 – November 23, 1803) was a Massachusetts State Navy officer and privateer who served in the American Revolutionary War. Life Haradan was born on November 11, 1744 in Gloucester, Massachusetts. As a boy he worked in Salem, Massachusetts for the prominent merchant and future Senator George Cabot. He joined the Massachusetts State Navy in July 1776 as first lieutenant onboard the 14-gun sloop ''Tyrannicide''. On board for two years, he participated in the capture of several prizes, becoming her commander in 1777. He had changes ships in 1778. The ''Tyrannicide'' went on to be scuttled during the Penobscot Expedition in 1779. In 1778, Haraden left the Massachusetts navy to began his career as a privateer, commanding the ''General Pickering'' (a letter of marque ship of 180 tons, with 16 6-pounder guns, and a crew of 106). On October 13, 1779, he engaged three British privateers off New Jersey simultaneously. In April 1780, he capt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Privateer
A privateer is a private person or vessel which engages in commerce raiding under a commission of war. Since robbery under arms was a common aspect of seaborne trade, until the early 19th century all merchant ships carried arms. A sovereign or delegated authority issued commissions, also referred to as letters of marque, during wartime. The commission empowered the holder to carry on all forms of hostility permissible at sea by the usages of war. This included attacking foreign vessels and taking them as prizes and taking crews prisoner for exchange. Captured ships were subject to condemnation and sale under prize law, with the proceeds divided by percentage between the privateer's sponsors, shipowners, captains and crew. A percentage share usually went to the issuer of the commission (i.e. the sovereign). Most colonial powers, as well as other countries, engaged in privateering. Privateering allowed sovereigns to multiply their naval forces at relatively low cost by mobilizi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camouflage
Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the bioluminescence, ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and octopuses, are capable of Active ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Publius Flavius Vegetius Renatus
Publius (or Flavius) Vegetius Renatus, known as Vegetius (), was a writer of the Later Roman Empire (late 4th century). Nothing is known of his life or station beyond what is contained in his two surviving works: ''Epitoma rei militaris'' (also referred to as '' De re militari''), and the lesser-known ''Digesta Artis Mulomedicinae'', a guide to veterinary medicine. He identifies himself in the opening of his work ''Epitoma rei militaris'' as a Christian. Dating of work The latest event alluded to in his ''Epitoma rei militaris'' is the death of the Emperor Gratian (383); the earliest attestation of the work is a ''subscriptio'' by Flavius Eutropius, writing in Constantinople in 450, which appears in one of two families of manuscripts, suggesting that a division of the manuscript tradition had already occurred. Despite Eutropius' location in Constantinople, the scholarly consensus is that Vegetius wrote in the Western Roman Empire.Walter Goffart. "The date and purposes of Vegetius' ...

Imagines (work By Philostratus)
''Imagines'' () is the Latin title of two works in ancient Greek by two authors, both named Philostratus, describing and explaining various artworks. The first of these two works called ''Imagines'' consists of two books (one consisting of an introduction and 31 chapters and the other of 34 chapters) are generally attributed to Philostratus of Lemnos, or possibly to his more famous father-in-law Philostratus of Athens. ''Imagines'' ostensibly describes 65 works of art seen by Philostratus in Naples. The entire work is framed in terms of explaining art, its symbols and meaning, to a young audience. The author of the work in the introduction states that the ten-year-old son of his host was the immediate cause of the composition of this work and that the author will structure the book and each of its chapters as if this boy is being addressed. The second ''Imagines'' (consisting of 17 chapters) is by the grandson of Philostratus of Lemnos, known as Philostratus the Younger.

Museum Für Antike Schifffahrt, Mainz 02
A museum is an institution dedicated to displaying or preserving culturally or scientifically significant objects. Many museums have exhibitions of these objects on public display, and some have private collections that are used by researchers and specialists. Museums host a much wider range of objects than a library, and they usually focus on a specific theme, such as the arts, science, natural history or local history. Public museums that host exhibitions and interactive demonstrations are often tourist attractions, and many draw large numbers of visitors from outside of their host country, with the most visited museums in the world attracting millions of visitors annually. Since the establishment of the earliest known museum in ancient times, museums have been associated with academia and the preservation of rare items. Museums originated as private collections of interesting items, and not until much later did the emphasis on educating the public take root. Etymology The ...

Stealth Ship
A stealth ship is a ship that employs stealth technology construction techniques in an effort to make it harder to detect by one or more of radar, visual, sonar, and infrared methods. These techniques borrow from stealth aircraft technology, although some aspects such as wake and acoustic signature reduction ( acoustic quieting) are unique to stealth ships' design. Although radar cross-section (RCS) reduction is a fairly new concept, many other forms of masking a ship have existed for centuries or even millennia. Shaping In designing a ship with a reduced radar signature, the main concerns are radar beams originating near or slightly above the horizon (as seen from the ship) coming from distant patrol aircraft, other ships, or sea-skimming anti-ship missiles with active radar seekers. Therefore, the shape of the ship avoids vertical surfaces, which are effective at reflecting such beams directly back to the emitter. Retro-reflective right angles are eliminated to avoid the ...
