Rocket Cruiser
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several operational roles from search-and-destroy to ocean escort to sea denial. The term "cruiser", which has been in use for several hundred years, has changed its meaning over time. During the Age of Sail, the term ''cruising'' referred to certain kinds of missions—independent scouting, commerce protection, or raiding—usually fulfilled by frigates or sloops-of-war, which functioned as the ''cruising warships'' of a fleet. In the middle of the 19th century, ''cruiser'' came to be a classification of the ships intended for cruising distant waters, for commerce raiding, and for scouting for the battle fleet. Cruisers came in a wide variety of sizes, from the medium-sized protected cruiser to large armored cruisers that were nearly as big (although not as powerful or as well-armored) as a pre-dreadnought b ...

World War I
World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a World war, global conflict between two coalitions: the Allies of World War I, Allies (or Entente) and the Central Powers. Fighting took place mainly in European theatre of World War I, Europe and the Middle Eastern theatre of World War I, Middle East, as well as in parts of African theatre of World War I, Africa and the Asian and Pacific theatre of World War I, Asia-Pacific, and in Europe was characterised by trench warfare; the widespread use of Artillery of World War I, artillery, machine guns, and Chemical weapons in World War I, chemical weapons (gas); and the introductions of Tanks in World War I, tanks and Aviation in World War I, aircraft.

Shore Bombardment
Naval gunfire support (NGFS), also known as naval surface fire support (NSFS), or shore bombardment, is the use of naval artillery to provide fire support for amphibious assault and other troops operating within their range. NGFS is one of several disciplines encompassed by the term ''naval fires''. Modern naval gunfire support is one of the three main components of amphibious warfare assault operations support, along with aircraft and ship-launched land-attack missiles. Shipborne guns have been used against shore defences since medieval naval warfare. Tactics Naval gunfire support is classified into two types: direct fire, where the ship has line of sight with the target (either visually or through the use of radar), and indirect fire, which, to be accurate, requires an artillery observer to adjust fire. When on the gun line, ships are particularly vulnerable to attack from aircraft coming from a landward direction and flying low to avoid radar detection, or from submarines b ...

Air Defense
Anti-aircraft warfare (AAW) is the counter to aerial warfare and includes "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It encompasses surface-based, subsurface (Submarine#Armament, submarine-launched), and air-based weapon systems, in addition to associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, army, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defense. Missile defense, Missile defense is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. Most modern anti-aircraft (AA) weapons systems are optimized for short-, medium-, or long-range air defence, although some systems may incorporate multiple weapons (such as both autocannons and surface-to-air missiles). 'Layered air defence' usually refers to multiple 't ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerial Warfare
Aerial warfare is the use of military aircraft and other flying machines in warfare. Aerial warfare includes bombers attacking tactical bombing, enemy installations or a concentration of enemy troops or Strategic bombing, strategic targets; fighter aircraft battling for air superiority, control of airspace; attack aircraft engaging in close air support against ground targets; naval aviation flying against sea and nearby land targets; Military glider, gliders, Military helicopter, helicopters and other aircraft to carry airborne forces such as paratroopers; aerial refueling tankers to extend operation time or range; and military transport aircraft to move cargo and personnel. Historically, military aircraft have included lighter-than-air balloons carrying artillery observers; lighter-than-air airships for bombing cities; various sorts of Reconnaissance aircraft, reconnaissance, Surveillance aircraft, surveillance, and Airborne early warning and control, early warning aircraft ca ...

Surface Combatant
Surface combatants (or surface ships or surface vessels) are a subset of naval warships which are designed for naval warfare, warfare on the surface of the water, with their own weapons and armed forces. They are generally ships built to fight other ships, submarines, aircraft or land targets, and can carry out several other missions including counter-narcotics operations and maritime interdiction. Their primary purpose is to engage space, air, surface, and submerged targets with weapons deployed from the ship itself, rather than by crewed carried craft.Naval Transformational Roadmap Office of Naval Research. Retrieved 2009-08-29. Surface ships include cruisers, destroyers, frigates, and corvettes, and several outdated types including battleships and battlecruisers. The category does not includ ...

Light Cruiser
A light cruiser is a type of small or medium-sized warship. The term is a shortening of the phrase "light armored cruiser", describing a small ship that carried armor in the same way as an armored cruiser: a protective belt and deck. Prior to this smaller cruisers had been of the protected cruiser model, possessing armored decks only. While lighter and smaller than other contemporary ships they were still true cruisers, retaining the extended radius of action and self-sufficiency to act independently around the world. Cruisers mounting larger guns and heavier armor relative to most light cruisers would come to be known as heavy cruisers, though the designation of 'light' versus 'heavy' cruisers would vary somewhat between navies. Through their history light cruisers served in a variety of roles, primarily on long-range detached patrol work, covering other military operations or global shipping lanes, as scouts and fleet support vessels for battle fleets, as destroyer command ship ...

Heavy Cruiser
A heavy cruiser was a type of cruiser, a naval warship designed for long range and high speed, armed generally with naval guns of roughly 203 mm (8 inches) in calibre, whose design parameters were dictated by the Washington Naval Treaty of 1922 and the London Naval Treaty of 1930. Heavy cruisers were generally larger, more heavily armed and more heavily armoured than light cruisers while being smaller, faster, and more lightly armed and armoured than battlecruisers and battleships. Heavy cruisers were not considered capital ships, unlike battlecruisers, battleships, and fleet carriers. Heavy cruisers were assigned a variety of roles ranging from commerce raiding to serving as 'cruiser-killers,' i.e. hunting and destroying similarly sized ships. The heavy cruiser is part of a lineage of ship design from 1915 through the early 1950s, although the term "heavy cruiser" only came into formal use in 1930. The heavy cruiser's immediate precursors were the light cruiser design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Naval Treaty
The London Naval Treaty, officially the Treaty for the Limitation and Reduction of Naval Armament, was an agreement between the United Kingdom, Empire of Japan, Japan, French Third Republic, France, Kingdom of Italy, Italy, and the United States that was signed on 22 April 1930. Seeking to address issues not covered in the 1922 Washington Naval Treaty, which had created tonnage limits for each nation's Surface combatant, surface warships, the new agreement regulated submarine warfare, further controlled cruisers and destroyers, and limited naval shipbuilding. Ratifications were exchanged in London on 27 October 1930, and the treaty went into effect on the same day, but it was largely ineffective. The treaty was registered in ''Treaty series#League of Nations, League of Nations Treaty Series'' on 6 February 1931. Conference The signing of the treaty remains inextricably intertwined with the ongoing negotiations, which began before the official start of the London Naval Confer ...

Caliber (artillery)
In artillery, caliber or calibre''Caliber'' is the American English spelling, while ''calibre'' is used in British English. is the internal diameter of a gun barrel, or, by extension, a relative measure of the barrel length. Rifled barrels Rifled barrels introduce ambiguity to measurement of caliber. A rifled bore consists of alternating grooves and lands. The distance across the bore from groove to groove is greater than the distance from land to land. Projectiles fired from rifled barrels must be of the full groove-to-groove diameter to be effectively rotated by the rifling, but the caliber has sometimes been specified as the land-to-land diameter before rifling grooves were cut. The depth of rifling grooves (and the consequent ambiguity) increases in larger calibers. Steel artillery projectiles may have a forward bourrelet section machined to a diameter slightly smaller than the original land-to-land dimension of the barrel and a copper driving band somewhat larger than ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p. 5. This is accomplished by means of its "draft marks". A merchant vessel has t ...

Washington Naval Treaty
The Washington Naval Treaty, also known as the Five-Power Treaty, was signed during 1922 among the major Allies of World War I, Allies of World War I, which agreed to prevent an arms race by limiting Navy, naval construction. It was negotiated at the Washington Naval Conference in Washington, D.C. from November 1921 to February 1922 and signed by the governments of the British Empire (including the United Kingdom, Canada, Australia, New Zealand, South Africa and India), United States, French Third Republic, France, Kingdom of Italy, Italy, and Empire of Japan, Japan. It limited the construction of battleships, battlecruisers and aircraft carriers by the signatories. The numbers of other categories of warships, including cruisers, destroyers, and submarines, were not limited by the treaty, but those ships were limited to 10,000 tons displacement (ship), displacement each. The treaty was finalized on February 6, 1922. Ratifications of it were exchanged in Washington on August 17, 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
