Cross-deck (naval Terminology)
Cross-deck (or cross-decking) is naval jargon which may refer to either informal, ad-hoc sharing of resources between naval vessels (historical usage), or the use of carrier decks (or vessel borne helipads) to host aircraft of foreign allies, aircraft from other ships in the same navy, or as re-fueling platforms for naval aircraft to extend flight operations beyond the range of the aircraft type. The operations may be entirely within a single navy, or between allied navies such as defined in the HOSTAC agreement. This may be required for ferrying aircraft or supplies, power projection operations involving fixed or rotary-wing aircraft, or to provide flexibility in operating limited numbers of specialized aircraft (such as the EA-6B Prowler electronic warfare aircraft) over a wide theatre of operations. Spare parts that can be lifted by helicopter are often crossed decked between ships operating compatible equipment (especially if they are the same ship class), to reduce redund ...

Arresting Gear
An arresting gear, or arrestor gear, is a mechanical system used to rapidly decelerate an aircraft as it lands. Arresting gear on aircraft carriers is an essential component of naval aviation, and it is most commonly used on CATOBAR and STOBAR aircraft carriers. Similar systems are also found at land-based airfields for expeditionary or emergency use. Typical systems consist of several steel wire ropes laid across the aircraft landing area, designed to be caught by an aircraft's tailhook. During a normal arrestment, the tailhook engages the wire and the aircraft's kinetic energy is transferred to hydraulic damping systems attached below the carrier deck. There are other related systems that use nets to catch aircraft wings or landing gear. These ''barricade'' and ''barrier'' systems are only used for emergency arrestments for aircraft without operable tailhooks. History Arresting cable systems were invented by Hugh Robinson and were used by Eugene Ely on his first landing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Infantry
Marines (or naval infantry) are military personnel generally trained to operate on both land and sea, with a particular focus on amphibious warfare. Historically, the main tasks undertaken by marines have included Raid (military), raiding ashore (often in support of naval objectives) and the Boarding (attack), boarding of vessels during naval warfare, ship-to-ship combat or capture of Prize (law), prize ships. Marines also assisted in maintaining security, discipline, and order aboard ships (reflecting the historically Impressment, pressed-nature of the rest of the ship's company and the risk of mutiny). While maintaining many of their historical roles, in modern times, marines also engage in duties including Rapid reaction force, rapid-response operations, humanitarian aid, disaster relief, special forces, special operations roles, and counter-terrorism, counter-terrorism operations. In most nations, marines are an integral part of that state's navy, such as the United Kingdom's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aérospatiale SA 330 Puma
The Aérospatiale SA 330 Puma is a four-bladed, twin-engined medium transport/utility helicopter designed and originally produced by the French aerospace manufacturer Sud Aviation. The Puma was developed as a new design during the mid-1960s in response to a French Army requirement for a medium-sized all-weather utility helicopter. Powered by a pair of Turbomeca Turmo turboshaft engines, it was designed to transport up to 16 seated soldiers, or a maximum of six Litter (rescue basket), litters with four attendants for casualty evacuation, along with carrying up to 2,500 kg of cargo either internally or using an external sling. The design of the Puma incorporated several innovations, including an automatic Blade inspection method, blade inspection system and relatively advanced anti-vibration measures integrated into the main Transmission (mechanical device), gearbox and main rotor blades. It was also designed to be capable of operating at night, under inhospitable flying condit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Army Light Aviation
The French Army Light Aviation ( (the army is officially called the 'Land Army' because the air force is officially called the 'Air Army')) is the Army aviation service of the French Army. ALAT was established on 22 November 1954 for observation, reconnaissance, assault and supply duties. History In 1912, the French military aviation was formally incorporated into the French Army, alongside the four longstanding divisions of the French Army, namely infantry, cavalry, artillery, and engineers. As such it played important role in WWI in support of the army : observation, artillery guidance, bombing and strafing, etc. but it also proved the air to be a battleground in itself, prompting the detachment of French Air Force from the army in 1934. After WWII, it was felt that, just like the navy, the army needed its own air branch, distinct from the air force, which led to ALAT's creation in 1954. Since it has participated in almost all French military engagements and humanitarian aid d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Helicopters
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of short take-off and landing (STOL) or short take-off and vertical landing ( STOVL) aircraft cannot perform without a runway. The Focke-Wulf Fw 61 was the first successful, practical, and fully controllable helicopter in 1936, while in 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production. Starting in 1939 and through 1943, Igor Sikorsky worked on the development of the VS-300, which over four iterations, became the basis for modern helicopters with a single main rotor and a single tail rotor. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Underway Replenishment
Underway replenishment (UNREP) (United States Navy, U.S. Navy) or replenishment at sea (RAS) (North Atlantic Treaty Organization/Commonwealth of Nations) is a method of transferring fuel, munitions, and stores from one ship to another while under way. First developed in the early 20th century, it was used extensively by the United States Navy as a logistics support technique in the Pacific theatre of World War II, permitting U.S. carrier task forces to remain at sea indefinitely. History Concept Prior to underway replenishment, coaling stations were the only way to refuel ships far from home. The Royal Navy had an unparalleled global logistics network of coaling stations and the world's largest collier (ship), collier fleet. This capability allowed the Navy to power projection, project naval power around the world and far from home ports. This had two disadvantages: the infrastructure was vulnerable to disruption or attack, and its use introduced a predictable pattern to naval ...

''Ad hoc'' is a List of Latin phrases, Latin phrase meaning literally for this. In English language, English, it typically signifies a solution designed for a specific purpose, problem, or task rather than a Generalization, generalized solution adaptable to collateral instances (compare with ''a priori and a posteriori, a priori''). Common examples include ad hoc committees and commissions created at the national or international level for a specific task, and the term is often used to describe arbitration (ad hoc arbitration). In other fields, the term could refer to a military unit created under special circumstances (see ''task force''), a handcrafted network protocol (e.g., ad hoc network), a temporary collaboration among geographically-linked franchise locations (of a given national brand) to issue advertising coupons, or a purpose-specific equation in mathematics or science.

Underway
Underway, or under way, is a nautical term describing the state of a vessel which is unconstrained from horizontal translational movement relative to the water and the ground. "Way" arises when there is sufficient water flow past the rudder of a vessel that it can be steered. A vessel is said to be underway if it meets the following criteria: * It is not aground * It is not at anchor * It has not been made fast to a dock The word dock () in American English refers to one or a group of human-made structures that are involved in the handling of boats or ships (usually on or near a shore). In British English, the term is not used the same way as in American Engl ..., the shore, or other stationary object. If a vessel is adrift and not being propelled by any instrument or device, it is said to be ''underway, not making way.'' "Under weigh" is a variation, coming from folk etymology, first used in 1749. "Under way" is likely from the Dutch ''onderweg'' or Middle Dutch ''on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Show Of Force
A show of force is a military operation intended to warn (such as a warning shot) or to intimidate an opponent by showcasing a capability or will to act if one is provoked. Shows of force may also be executed by police forces and other armed, non-military groups. Function Shows of force have historically been undertaken mostly by a military actor unwilling to engage in all-out hostilities, but fearing to 'lose face' (to appear weak). By performing a carefully calculated provocation, the opponent is to be shown that violent confrontation remains an option, and there will be no backing off on the principle that the show of force is to defend. Shows of force may be actual military operations, but in times of official peace, they may also be limited to military exercises. Shows of force also work on a smaller scale: military forces on a tactical level using mock attacks to deter potential opponents, especially when a real attack on suspected (but unconfirmed) enemies might harm ...
