Naval Decoy IDS300
Naval Decoy IDS300 (Inflatable Decoy System) is a passive, off-board, octahedral, corner reflector decoy of the Royal Navy's Type 45 destroyer and the US Navy's destroyer, forming part of a layered defence to counter anti-ship missiles. Unlike chaff, the decoy is persistent and will float for up to three hours in sea state 4. Jane's was first to report the United Kingdom was looking for a new floating decoy as part of a program known as the Naval Passive Off-Board Decoy (N-POD), on March 3, 2019. In US Navy service, it is designated as the Mk 59 decoy launching system. The system is made by Irvin Aerospace Ltd, Hertfordshire in the United Kingdom. Deployment The decoy is launched out of a deck-mounted tube and self-inflates on the sea surface before being released to free-float past the stern to mimic a ship's radar and radio signatures. The deployment and inflation process takes seconds and the decoy is completely independent, requiring no further input from the ship. Typi ...

Naval Warfare
Naval warfare is combat in and on the sea, the ocean, or any other battlespace involving a major body of water such as a large lake or wide river. Mankind has fought battles on the sea for more than 3,000 years. Even in the interior of large landmasses, transportation before the advent of extensive railroads was largely dependent upon rivers, canals, and other navigable waterways. The latter were crucial in the development of the modern world in Britain, the Low Countries and northern Germany, for they enabled the bulk movement of goods and raw materials without which the Industrial Revolution would not have occurred. Before 1800, war materials were largely moved by river barges or sea vessels and needed a naval defence against enemies. History Mankind has fought battles on the sea for more than 3,000 years.

Military Decoys
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nulka
Nulka is an Australian-designed and -developed active missile decoy built by an American/ Australian collaboration. Used aboard warships of the United States Navy (USN), Royal Australian Navy (RAN), United States Coast Guard (USCG), and Royal Canadian Navy, Nulka is a rocket-propelled, disposable, offboard, active decoy designed to lure anti-ship missiles away from their targets. It has a unique design in that it hovers in mid-air while drawing the incoming anti-ship missile. The hovering rocket concept was initiated in Australia by the Defence Science and Technology Organisation (DSTO), and the system was designed, developed and then manufactured by AWA Defence Industries ( AWADI) (now BAE Systems Australia). BAE refers to Nulka as a " soft-kill defence system". The word "Nulka" is of Australian Aboriginal origin and means "be quick". The Nulka consists of the missile itself enclosed in a hermetically sealed canister. This canister is then contained in a dedicated launcher mod ...

Electronic Warfare
Electronic warfare (EW) is any action involving the use of the electromagnetic spectrum (EM spectrum) or directed energy to control the spectrum, attack an enemy, or impede enemy assaults. The purpose of electronic warfare is to deny the opponent the advantage of—and ensure friendly unimpeded access to—the EM spectrum. EW can be applied from air, sea, land, and/or space by crewed and uncrewed systems, and can target communication, radar, or other military and civilian assets. The electromagnetic environment Military operations are executed in an information environment increasingly complicated by the electromagnetic spectrum. The electromagnetic spectrum portion of the information environment is referred to as the electromagnetic environment (EME). The recognized need for military forces to have unimpeded access to and use of the electromagnetic environment creates vulnerabilities and opportunities for electronic warfare in support of military operations. Within the informa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Countermeasure
An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile terminal homers. History The first example of electronic countermeasures being applied in a combat situation took place during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AN/SLQ-49 Chaff Buoy Decoy System
The AN/SLQ-49 Chaff Buoy Decoy System, commonly referred to as "Rubber Duck", consists of inflatable radar-reflecting decoy buoys. It is used by the U.S. Navy, Royal Navy, and other NATO countries. The decoy is designed to seduce radar-guided anti-ship missiles by simulating the radar Radar is a detection system that uses radio waves to determine the distance ('' ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, w ... cross section of a ship, presenting itself as a more attractive target than the ship. The system is deployed in pairs. The deployment process takes a few seconds. When deployed, the system launches into the water two octahedron-shaped inflatable decoy floats, connected by a cable. They can last up to 3 hours in sea state 4. The AN/SLQ-49 has been in operation since 1985. Originally designed to confuse or distract enemy radar operators, it has demonst ...

Littoral Waters
The littoral zone or nearshore is the part of a sea, lake, or river that is close to the shore. In coastal ecology, the littoral zone includes the intertidal zone extending from the high water mark (which is rarely inundated), to coastal areas that are permanently submerged — known as the ''foreshore'' — and the terms are often used interchangeably. However, the geographical meaning of ''littoral zone'' extends well beyond the intertidal zone to include all neritic waters within the bounds of continental shelves. Etymology The word ''littoral'' may be used both as a noun and as an adjective. It derives from the Latin noun ''litus, litoris'', meaning "shore". (The doubled ''t'' is a late-medieval innovation, and the word is sometimes seen in the more classical-looking spelling ''litoral''.) Description The term has no single definition. What is regarded as the full extent of the littoral zone, and the way the littoral zone is divided into subregions, varies in different c ...

Hertfordshire
Hertfordshire ( or ; often abbreviated Herts) is one of the home counties in southern England. It borders Bedfordshire and Cambridgeshire to the north, Essex to the east, Greater London to the south, and Buckinghamshire to the west. For government statistical purposes, it forms part of the East of England region. Hertfordshire covers . It derives its name – via the name of the county town of Hertford – from a Hart (deer), hart (stag) and a Ford (crossing), ford, as represented on the county's coat of arms and on the Flag of Hertfordshire, flag. Hertfordshire County Council is based in Hertford, once the main market town and the current county town. The largest settlement is Watford. Since 1903 Letchworth has served as the prototype Garden city movement, garden city; Stevenage became the first town to expand under post-war Britain's New Towns Act 1946, New Towns Act of 1946. In 2013 Hertfordshire had a population of about 1,140,700, with Hemel Hempstead, Stevenage, Watford ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Octahedral
In geometry, an octahedron (plural: octahedra, octahedrons) is a polyhedron with eight faces. The term is most commonly used to refer to the regular octahedron, a Platonic solid composed of eight equilateral triangles, four of which meet at each vertex. A regular octahedron is the dual polyhedron of a cube. It is a rectified tetrahedron. It is a square bipyramid in any of three orthogonal orientations. It is also a triangular antiprism in any of four orientations. An octahedron is the three-dimensional case of the more general concept of a cross polytope. A regular octahedron is a 3-ball in the Manhattan () metric. Regular octahedron Dimensions If the edge length of a regular octahedron is ''a'', the radius of a circumscribed sphere (one that touches the octahedron at all vertices) is :r_u = \frac a \approx 0.707 \cdot a and the radius of an inscribed sphere (tangent to each of the octahedron's faces) is :r_i = \frac a \approx 0.408\cdot a while the midradius, which ...
