Link 11
TADIL-A/Link 11 is a secure half-duplex tactical data link used by NATO to exchange digital data. It was originally developed by a joint committee including members from the Canadian Navy, US Navy and Royal Navy to pass accurate targeting information between ships. The final standard was signed in Ottawa in November 1957, where the British proposed the name "TIDE" for "Tactical International Data Exchange". It was later made part of the NATO STANAG standardization process. The system operates on two frequencies, one in the high frequency (HF) range for over-the-horizon (OTH) communications, and another in the ultra high frequency (UHF) range that uses much smaller antennas and is suitable for smaller ships but lacks the OTH performance. The system broadcasts packets of 30 bits length, with 6 bits of error correction and 24 bits of payload data. The payload is encrypted. Link 14 was adopted at the same time as a low-end counterpart to Link 11. Link 14 is essentially a digital te ...

Royal Netherlands Navy
The Royal Netherlands Navy ( nl, Koninklijke Marine, links=no) is the naval force of the Kingdom of the Netherlands. During the 17th century, the navy of the Dutch Republic (1581–1795) was one of the most powerful naval forces in the world and played an active role in the Anglo-Dutch Wars, the Franco-Dutch War, and wars against Spain and several other European powers. The Batavian Navy of the later Batavian Republic (1795–1806) and Kingdom of Holland (1806–1810) played an active role in the Napoleonic Wars, though mostly dominated by French interests. After the establishment of the modern Kingdom of the Netherlands, it served an important role in protecting Dutch colonial rule, especially in Southeast Asia, and would play a minor role in World War II, especially against the Imperial Japanese Navy. Since World War II, the Royal Netherlands Navy has taken part in expeditionary peacekeeping operations. Bases The main naval base is in Den Helder, North Holland. Secondary na ...

Amphibious Warfare
Amphibious warfare is a type of offensive military operation that today uses naval ships to project ground and air power onto a hostile or potentially hostile shore at a designated landing beach. Through history the operations were conducted using ship's boats as the primary method of delivering troops to shore. Since the Gallipoli Campaign, specialised watercraft were increasingly designed for landing troops, material and vehicles, including by landing craft and for insertion of commandos, by fast patrol boats, zodiacs (rigid inflatable boats) and from mini-submersibles. The term ''amphibious'' first emerged in the United Kingdom and the United States during the 1930s with introduction of vehicles such as Vickers-Carden-Loyd Light Amphibious Tank or the Landing Vehicle Tracked.The first LVT prototypes were named ''Alligator'' and '' Crocodile'', though neither species is actual amphibian Amphibious warfare includes operations defined by their type, purpose, scale an ...

Landing Platform Dock
An amphibious transport dock, also called a landing platform dock (LPD), is an amphibious warfare ship, a warship that embarks, transports, and lands elements of a landing force for expeditionary warfare missions. Several navies currently operate this kind of ship. The ships are generally designed to transport troops into a war zone by sea, primarily using landing craft, although invariably they also have the capability to operate transport helicopters. Amphibious transport docks perform the mission of amphibious transports, amphibious cargo ships, and the older dock landing ships (LSD) by incorporating both a flight deck and a well deck that can be ballasted and deballasted to support landing craft or amphibious vehicles. The main difference between LSDs and LPDs is that while both have helicopter landing decks, the LPD also has hangar facilities for protection and maintenance. In the United States Navy, the newer class of LPD has succeeded the older classes of LSDs, and bot ...

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. 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 they waited for th ...

Boeing CH-47 Chinook
The Boeing CH-47 Chinook is a tandem rotor helicopter developed by American rotorcraft company Vertol and manufactured by Boeing Vertol. The Chinook is a heavy-lift helicopter that is among the heaviest lifting Western helicopters. Its name, Chinook, is from the Native American Chinook people of Oregon and Washington state. The Chinook was originally designed by Vertol, which had begun work in 1957 on a new tandem-rotor helicopter, designated as the Vertol Model 107 or V-107. Around the same time, the United States Department of the Army announced its intention to replace the piston engine–powered Sikorsky CH-37 Mojave with a new, gas turbine–powered helicopter. During June 1958, the U.S. Army ordered a small number of V-107s from Vertol under the ''YHC-1A'' designation; following testing, it came to be considered by some Army officials to be too heavy for the assault missions and too light for transport purposes. While the YHC-1A would be improved and adopted by the U.S. ...

AS-532
The Eurocopter AS532 Cougar (now Airbus Helicopters H215M) is a twin-engine, medium-weight, multipurpose helicopter developed by France. The AS532 is a development and upgrade of the Aérospatiale SA 330 Puma in its militarized form. Its civilian counterpart is the Eurocopter AS332 Super Puma. The AS532 has been further developed as the Eurocopter EC725. Design and development The AS332 Super Puma, designed as a growth version to replace the SA 330 Puma, first flew in September 1977. It was fitted with two 1,330 kW Turbomeca Makila 1A1 turboshaft engines, composite rotor blades, improved landing gear and a modified tailfin. In 1990 all military Super Puma designations were changed from "AS 332" to "AS 532 Cougar" to distinguish between the civil and military variants of the helicopter. Canada had considered purchasing the Cougar to replace their CH-113 Labrador, but opted in the end to purchase the CH-149 Cormorant. In 2012 France began a €288.8m project (€11.1m/un ...

Machine Gun
A machine gun is a fully automatic, rifled autoloading firearm designed for sustained direct fire with rifle cartridges. Other automatic firearms such as automatic shotguns and automatic rifles (including assault rifles and battle rifles) are typically designed more for firing short bursts rather than continuous firepower, and are not considered true machine guns. As a class of military kinetic projectile weapon, machine guns are designed to be mainly used as infantry support weapons and generally used when attached to a bipod or tripod, a fixed mount or a heavy weapons platform for stability against recoils. Many machine guns also use belt feeding and open bolt operation, features not normally found on other infantry firearms. Machine guns can be further categorized as light machine guns, medium machine guns, heavy machine guns, general purpose machine guns and squad automatic weapons. Similar automatic firearms of caliber or more are classified as autocannons, rat ...
