Broadside (naval)
A broadside is the side of a ship, or more specifically the 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. Firing all guns on one side of the ship became known as a "broadside". The cannon of 18th-century 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 other ship.Platt (1993) p. 18 History Since a ...

Square-rigged
Square rig is a generic type of sail and rigging arrangement in which the primary driving sails are carried on horizontal spars which are perpendicular, or square, to the keel of the vessel and to the masts. These spars are called ''yards'' and their tips, outside the lifts, are called the ''yardarms.'' A ship mainly rigged so is called a square-rigger. The square rig is aerodynamically the most efficient running rig (i.e., sailing downwind), and stayed popular on ocean-going sailing ships until the end of the Age of Sail. The last commercial sailing ships, windjammers, were usually square-rigged four-masted barques. History The oldest archaeological evidence of use of a square-rig on a vessel is an image on a clay disk from Mesopotamia from 5000 BC. Single sail square rigs were used by the ancient Egyptians, the Phoenicians, the Greeks, the Romans, and the Celts. Later the Scandinavians, the Germanic peoples, and the Slavs adopted the single square-rigged sail, with it bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salvo
A salvo is the simultaneous discharge of artillery or firearms including the firing of guns either to hit a target or to perform a salute. As a tactic in warfare, the intent is to cripple an enemy in one blow and prevent them from fighting back. Overview Troops armed with muzzleloaders required time to refill their arms with gunpowder and shot. Gun drills were designed to enable an almost continuous rain of fire on the enemy by lining troops into ranks, allowing one rank to fire a salvo, or volley, while the other ranks prepared their guns for firing. The term is commonly used to describe the firing of broadsides by warships, especially battleships. During fleet engagements in the days of sail, from 17th century until the 19th century, ships of the line were maneuvered with the objective of bringing the greatest possible number of cannon to bear on the enemy and to discharge them in a salvo, causing enough damage and confusion as to allow time for the cannon to be sw ...

Barrage (artillery)
In military usage, a barrage is massed sustained artillery fire ( shelling) aimed at a series of points along a line. In addition to attacking any enemy in the kill zone, a barrage intends to suppress enemy movements and deny access across that line of barrage. The impact points along the line may be 20–30 yards/meters apart, with the total line length of the barrage zone anything from a few hundred to several thousand yards/meters long. Barrages can consist of multiple such lines, usually about 100 yards/meters apart, with the barrage shifting from one line to the next over time, or several lines may be targeted simultaneously. A barrage may involve a few or many artillery batteries, or even (rarely) a single gun. Typically each gun in a barrage, using indirect fire, will fire continuously at a steady rate at its assigned point for an assigned time before moving onto the next target, following the barrage's detailed timetable. Barrages typically use high-explosive shells, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Short Ton
The short ton (symbol tn) is a measurement unit equal to . It is commonly used in the United States, where it is known simply as a ton, although the term is ambiguous, the single word being variously used for short, long, and metric ton. The various tons are defined as units of mass.Butcher, Crown and Gentry, NIST Special Publication 1038, The International System of Units (SI) – Conversion Factors for General Use, 2006 They are sometimes used as units of weight, the force exerted by a mass at standard gravity (e.g., short ton-force). One short ton exerts a weight at one standard gravity of 2,000 pound-force (lbf). United States In the United States, a short ton is usually known simply as a "ton", without distinguishing it from the tonne (), known there as the "metric ton", or the long ton also known as the "imperial ton" (). There are, however, some U.S. applications where unspecified ''tons'' normally mean long tons (for example, naval ships) or metric tons (world grain ...

USS Iowa (BB-61)
USS ''Iowa'' (BB-61) is a retired battleship, the lead ship of her class, and the fourth in the United States Navy to be named after the state of Iowa. Owing to the cancellation of the s, ''Iowa'' is the last lead ship of any class of United States battleships and was the only ship of her class to serve in the Atlantic Ocean during World War II. During World War II, she carried President Franklin D. Roosevelt across the Atlantic to Mers El Kébir, Algeria, en route to a conference of vital importance in 1943 in Tehran with Prime Minister Winston Churchill of the United Kingdom and Joseph Stalin, leader of the Soviet Union. When transferred to the Pacific Fleet in 1944, ''Iowa'' shelled beachheads at Kwajalein and Eniwetok in advance of Allied amphibious landings and screened aircraft carriers operating in the Marshall Islands. She also served as the Third Fleet flagship, flying Admiral William F. Halsey's flag at the Japanese surrender in Tokyo Bay. During the Korean War, ...

Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th Century, these hoods were known as turrets. Modern warships have gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battleship
A battleship is a large armour, armored warship with a main artillery battery, battery consisting of large caliber guns. It dominated naval warfare in the late 19th and early 20th centuries. The term ''battleship'' came into use in the late 1880s to describe a type of ironclad warship,Stoll, J. ''Steaming in the Dark?'', Journal of Conflict Resolution Vol. 36 No. 2, June 1992. now referred to by historians as pre-dreadnought battleships. In 1906, the commissioning of into the United Kingdom's Royal Navy heralded a revolution in the field of battleship design. Subsequent battleship designs, influenced by HMS ''Dreadnought'', were referred to as "dreadnoughts", though the term eventually became obsolete as dreadnoughts became the only type of battleship in common use. Battleships were a symbol of naval dominance and national might, and for decades the battleship was a major factor in both diplomacy and military strategy.Sondhaus, L. ''Naval Warfare 1815–1914'', .

Chase Gun
A chase gun (or chaser), usually distinguished as bow chaser and stern chaser, was a cannon mounted in the bow (aiming forward) or stern (aiming backward) of a sailing ship. They were used to attempt to slow down an enemy ship either chasing (pursuing) or being chased, when the ship's broadside could not be brought to bear. Typically, the chasers were used to attempt to damage the rigging and thereby cause the target to lose performance. Bow chasers could be regular guns brought up from the gundeck and aimed through specially cut-out ports on either side of the bowsprit, or dedicated weapons made with an unusually long bore and a relatively light ball, and mounted in the bow. Stern chasers could also be improvised, or left permanently in the cabins at the stern, covered up and used as part of the furniture. Development In the Age of Sail, shiphandling had been brought to a high art, and chases frequently lasted for hours or sometimes days, as each crew fine-tuned their sails t ...
