Expeditionary Transfer Dock
An Expeditionary Transfer Dock (ESD), formerly the Mobile Landing Platform (MLP), is designed to be a semi-submersible, flexible, modular platform providing the US Navy with the capability to perform large-scale logistics movements such as the transfer of vehicles and equipment from sea to shore. These ships significantly reduce the dependency on foreign ports and provide support in the absence of port availability. The class also houses a sub-class variant called the Expeditionary Mobile Base (ESB), formerly the Afloat Forward Staging Base (AFSB). The ESD and ESB are part of a new ship class added in 2015 with an E as a new designator, similar to the L-class amphibious ships, S-class submarines, A-class auxiliaries and more. These three E-class ships were previously listed as seabasing ships in the ''Naval Vessel Register''. In May 2011, General Dynamics National Steel and Shipbuilding Company, NASSCO received a $744 million contract modification to fully fund the construction of ...

Minesweeping
Minesweeping is the practice of removing explosive naval mines, usually by a specially designed ship called a minesweeper using various measures to either capture or detonate the mines, but sometimes also with an aircraft made for that purpose. Minesweeping has been practiced since the advent of naval mining in 1855 during the Crimean War. The first minesweepers date to that war and consisted of British rowboats trailing Grappling hook, grapnels to snag the mines. By ship A sweep is either a contact sweep, a wire dragged through the water by one or two ships to cut the mooring wire of floating mines, or a distance sweep that mimics a ship to detonate the mines. The sweeps are dragged by minesweeper (ship), minesweepers, either purpose-built military ships or converted Commercial trawler, trawlers. Each run covers between , and the ships must move slowly in a straight line, making them vulnerable to enemy fire. This was exploited by the Turkish army in the Battle of Gallipoli i ...

Piracy
Piracy is an act of robbery or criminal violence by ship or boat-borne attackers upon another ship or a coastal area, typically with the goal of stealing cargo and valuable goods, or taking hostages. Those who conduct acts of piracy are called pirates, and vessels used for piracy are called pirate ships. The earliest documented instances of piracy were in the 14th century BC, when the Sea Peoples, a group of ocean raiders, attacked the ships of the Aegean and Mediterranean civilisations. Narrow channels which funnel shipping into predictable routes have long created opportunities for piracy, as well as for privateering and commerce raiding. Historic examples of such areas include the waters of Gibraltar, the Strait of Malacca, Madagascar, the Gulf of Aden, and the English Channel, whose geographic structures facilitated pirate attacks. The term ''piracy'' generally refers to maritime piracy, although the term has been generalized to refer to acts committed on land, ...

USNS Lewis B
United States Naval Ship (USNS) is the prefix designation given to non- commissioned ships that are property of the United States Navy (USN). Definition United States Naval Ships are unarmed auxiliary support vessels owned by the U.S. Navy and operated in non-commissioned service by Military Sealift Command with a civilian crew. Some ships include a small military complement to carry out communication and special mission functions, or for force protection. In comparison, U.S. Navy ships commissioned into military service have the designation " USS", are armed, and are crewed by U.S. Navy personnel. Additionally, the United States Naval Ships hull classification symbol begins with "T-" to denote its civilian crew. The USNS prefix can be assigned only while the ship is owned by the U.S. Navy. If, after being taken out of service, the ship is transferred to the Maritime Administration the prefix reverts to a civilian ship prefix such as the case of SS ''Comet''. See also ...

MH-53E Sea Dragon
The Sikorsky CH-53E Super Stallion is a heavy lift helicopter operated by the United States military. As the Sikorsky S-80, it was developed from the CH-53 Sea Stallion, mainly by adding a third engine, adding a seventh blade to the main rotor, and canting the tail rotor 20°. It was built by Sikorsky Aircraft for the United States Marine Corps. Developed in the 1970s, it entered service in 1981, and is planned to be in service into the 2030s. It is one of the largest military helicopters in service, and is operated from U.S. Navy ships or from land. The Navy also operates the MH-53E Sea Dragon which fills the United States Navy's need for long-range minesweeping or airborne mine countermeasures missions, and performs heavy-lift duties for the Navy. The Sikorsky CH-53K King Stallion, which has new engines, new composite rotor blades, and a wider aircraft cabin, is set to replace the CH-53E and enter service in the 2020s. Most of the Super Stallions in service are configured as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
F-35B
The Lockheed Martin F-35 Lightning II is an American family of single-seat, single-engine, supersonic stealth strike fighters. A multirole combat aircraft designed for both air superiority and strike missions, it also has electronic warfare and intelligence, surveillance, and reconnaissance capabilities. Lockheed Martin is the prime F-35 contractor with principal partners Northrop Grumman and BAE Systems. The aircraft has three main variants: the conventional takeoff and landing (CTOL) F-35A, the short take-off and vertical-landing (STOVL) F-35B, and the carrier variant (CV) catapult-assisted take-off but arrested recovery (CATOBAR) F-35C. The aircraft descends from the Lockheed Martin X-35, which in 2001 beat the Boeing X-32 to win the Joint Strike Fighter (JSF) program intended to replace the F-16 Fighting Falcon, F/A-18 Hornet, and the McDonnell Douglas AV-8B Harrier II "jump jet", among others. Its development is principally funded by the United States, with addit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bell Boeing V-22 Osprey
The Bell Boeing V-22 Osprey is an American multi-use, tiltrotor military transport and cargo aircraft with both vertical takeoff and landing (VTOL) and short takeoff and landing (STOL) capabilities. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft. The V-22 is operated by the United States and Japan, and is not only a new aircraft design, but a new type of aircraft that entered service in the 2000s, a tiltrotor compared to fixed wing and helicopter designs. The V-22 first flew in 1989 and after a long development was fielded in 2007. The design combines the vertical takeoff ability of a helicopter with the speed and range of a fixed-wing airplane. The failure of Operation Eagle Claw in 1980 during the Iran hostage crisis underscored that there were military roles for which neither conventional helicopters nor fixed-wing transport aircraft were well-suited.

Flight Deck
The flight deck of an aircraft carrier is the surface on which its aircraft take off and land, essentially a miniature airfield at sea. On smaller naval ships which do not have aviation as a primary mission, the landing area for helicopters and other VTOL aircraft is also referred to as the flight deck. The official U.S. Navy term for these vessels is "air-capable ships". Flight decks have been in use upon ships since 1910, the American pilot Eugene Ely being the first individual to take off from a warship. Initially consisting of wooden ramps built over the forecastle of capital ships, a number of battlecruisers, including the British and , the American and , and the Japanese ''Akagi'' and battleship ''Kaga'', were converted to aircraft carriers during the interwar period. The first aircraft carrier to feature a full-length flight deck, akin to the configuration of the modern vessels, was the converted liner which entered service in 1918. The armoured flight deck was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hangar
A hangar is a building or structure designed to hold aircraft or spacecraft. Hangars are built of metal, wood, or concrete. The word ''hangar'' comes from Middle French ''hanghart'' ("enclosure near a house"), of Germanic origin, from Frankish *''haimgard'' ("home-enclosure", "fence around a group of houses"), from *''haim'' ("home, village, hamlet") and ''gard'' ("yard"). The term, ''gard'', comes from the Old Norse ''garðr'' ("enclosure, garden"). Hangars are used for protection from the weather, direct sunlight and for maintenance, repair, manufacture, assembly and storage of aircraft. History The Wright brothers stored and repaired their aircraft in a wooden hangar constructed in 1902 at Kill Devil Hills in North Carolina for their Glider aircraft, glider. After completing design and construction of the ''Wright Flyer'' in Ohio, the brothers returned to Kill Devil Hills only to find their hangar damaged. They repaired the structure and constructed a new workshop while t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
