AIM-120
The AIM-120 Advanced Medium-Range Air-to-Air Missile (AMRAAM) ( ) is an American beyond-visual-range air-to-air missile capable of all-weather day-and-night operations. It uses active transmit-receive radar guidance instead of semi-active receive-only radar guidance. When an AMRAAM missile is launched, NATO pilots use the brevity code " Fox Three". The AMRAAM largely replaced the AIM-7 Sparrow as the principal beyond-visual-range air-to-air missile in U.S. inventory. more than 14,000 had been produced for the United States Air Force, the United States Navy, and 33 international customers. The AMRAAM has been used in several engagements, achieving 16 air-to-air kills in conflicts over Iraq, Bosnia, Kosovo, India, and Syria. In the long term, it is expected to eventually be replaced by the long range AIM-260 JATM in U.S. service and the MBDA Meteor in some European countries. Origins AIM-7 Sparrow MRM The AIM-7 Sparrow medium range missile (MRM) was purchased by the US Navy f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air-to-air Missile
An air-to-air missile (AAM) is a missile fired from an aircraft for the purpose of destroying another aircraft (including unmanned aircraft such as cruise missiles). AAMs are typically powered by one or more rocket motors, usually solid-fuel rocket, solid fueled but sometimes liquid-fuel rocket, liquid fueled. Ramjet engines, as used on the Meteor (missile), Meteor, are emerging as propulsion that will enable future medium- to long-range missiles to maintain higher average speed across their engagement envelope. Air-to-air missiles are broadly put in two groups. Those designed to engage opposing aircraft at ranges of around 30 km to 40 km maximum are known as short-range or "within visual range" missiles (SRAAMs or WVRAAMs) and are sometimes called "dogfight" missiles because they are designed to optimize their agility rather than range. Most use infrared guidance and are called heat-seeking missiles. In contrast, medium- or long-range missiles (MRAAMs or LRAAMs), which ...

Beyond-visual-range Missile
A beyond-visual-range missile (BVR missile) or beyond-visual-range air-to-air missile (BVRAAM) is an air-to-air missile that is capable of engaging at ranges around or beyond. This range has been achieved using dual pulse rocket motors or booster rocket motor and ramjet sustainer motor. Medium-range, long-range, and very-long-range air-to-air missiles fall under the category of beyond-visual-range missiles. Older BVR missiles generally used the semi-active radar homing, and modern BVR missiles use the active radar homing missile guidance, guidance. In addition to the range capability, the missile must also be capable of tracking its target at this range or of acquiring the target in flight. Systems in which a mid-course correction is transmitted to the missile have been used. History Early air-to-air missiles used semi-active radar homing guidance, that is the missile used the radiation produced by the launching aircraft to guide it to the target. The latest generation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hughes Aircraft
The Hughes Aircraft Company was a major American aerospace company, aerospace and defense contractor founded on February 14, 1934 by Howard Hughes in Glendale, California, as a division of the Hughes Tool Company. The company produced the Hughes H-4 Hercules aircraft, the atmospheric entry probe carried by the Galileo (spacecraft), ''Galileo'' spacecraft, and the AIM-4 Falcon guided missile. Hughes Aircraft was founded to build Hughes' Hughes H-1 Racer, H-1 Racer world speed record aircraft, and later modified other aircraft for his transcontinental and global circumnavigation speed record flights. The company relocated to Culver City, California, in 1940 and began manufacturing aircraft parts as a subcontractor. Hughes attempted to mold it into a major military aircraft manufacturer during World War II. However, its early military projects ended in failure, with millions of dollars in U.S. government funds expended for only a handful of prototypes, resulting in a highly publiciz ...

Fox (code Word)
Fox is a brevity code used by NATO aircraft pilot, pilots to signal the simulated or actual release of an Air-to-air missile, air-to-air munition or other combat function. Army aviation elements may use a different nomenclature, as the nature of helicopter-fired weapons is almost always Air-to-surface missile, air-to-surface. "Fox" is short for "foxtrot", the NATO NATO phonetic alphabet, phonetic designation for the letter "F", which is short for "fire". A fighter pilot announcing that a weapon has been fired is intended to help avoid friendly fire, alerting other pilots to avoid maneuvering into the path of the munition. The term has also been seen in use with the People's Liberation Army Air Force, PLAAF. There are three variations of the ''Fox'' brevity word in use, with a number added to the end of ''Fox'' to describe the primary type of sensors the launched munition possesses (if applicable). This includes autocannons and collisions. ;Fox one: Indicates launch of a semi-act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Radar Homing
Active radar homing (ARH) is a missile guidance method in which a missile contains a radar transceiver (in contrast to semi-active radar homing, which uses only a passive radar, receiver) and the electronics necessary for it to find and track its target autonomously. The NATO brevity code for an air-to-air active radar homing missile launch is fox (code word), Fox Three. Advantages There are two major advantages to active radar homing: * As the missile is tracking the target it is going to be much closer to the target than the launching platform during the terminal phase, thus the missile's tracking can be much more accurate and better resistant to electronic countermeasures. Active radar homing missiles have some of the best kill probability, kill probabilities, along with missiles employing track-via-missile guidance. * Because the missile is totally autonomous during the terminal phase, the launch platform does not need to have its radar enabled at all during this phase, an ...

2019 Jammu And Kashmir Airstrikes
On 27 February 2019, the Pakistan Air Force (PAF) conducted six airstrikes at multiple locations in Indian-administered Jammu and Kashmir (J&K). The airstrikes were part of the PAF military operation codenamed Operation Swift Retort and were conducted in retaliation to the Indian Air Force (IAF) airstrike in Balakot just a day before on 26 February. It was the first time since 1971 that both countries' airforces had conducted airstrikes on each other's territory across the Line of Control (LoC). India conducted an airstrike in Balakot on 26 February while Pakistan responded by conducting airstrikes in Indian-administered Kashmir. Following Pakistan's airstrikes, Indian Air Force (IAF) jets started pursuing Pakistan Air Force (PAF) jets. In the resulting dogfight, Pakistan claimed to have shot down two Indian jets and captured one Indian pilot, Abhinandan Varthaman. Indian officials acknowledged that one IAF jet was lost. One IAF Mil Mi-17 helicopter was also lost due to a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Datalink
A data link is a means of telecommunications link, connecting one location to another for the purpose of transmitting and receiving digital information (data communication). It can also refer to a set of electronics assemblies, consisting of a transmitter and a receiver (two pieces of data terminal equipment) and the interconnecting data telecommunication circuit. These are governed by a link protocol enabling digital data to be transferred from a data source to a data sink. Types There are at least three types of basic data-link configurations that can be conceived of and used: * Simplex communications, most commonly meaning all communications in one direction only. * Half-duplex communications, meaning communications in both directions, but not both ways simultaneously. * Duplex (telecommunications), Duplex communications, communications in both directions simultaneously. Aviation In civil aviation, a data-link system (known as Controller Pilot Data Link Communications) is use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mid-course Update
Command guidance is a type of missile guidance in which a ground station or aircraft relay signals to a guided missile via radio control or through a wire connecting the missile to the launcher and tell the missile where to steer to intercept its target. This control may also command the missile to detonate, even if the missile has a fuze. Typically, the system giving the guidance commands is tracking both the target and the missile or missiles via radar. It determines the positions and velocities of a target and a missile, and calculates whether their paths will intersect. If not, the guidance system will relay commands to a missile, telling it to move the fins in a way that steers in the direction needed to maneuver to an intercept course with the target. If the target maneuvers, the guidance system can sense this and update the missiles' course continuously to counteract such maneuvering. If the missile passes close to the target, either its own proximity or contact fuze will ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coulsdon
Coulsdon (, traditionally pronounced ) is a town in south London, England, within the London Borough of Croydon. Coulsdon was an ancient parish in the county of Surrey that included the settlements of Purley and Kenley. It was merged with Sanderstead in 1915 to form the Coulsdon and Purley Urban District and has formed part of Greater London since 1965. History The location forms part of the North Downs. The hills contain chalk and flint. A few dry valleys with natural underground drainage merge and connect to the main headwater of the River Wandle, as a winterbourne (stream), so commonly called "the Bourne". Although this breaks onto the level of a few streets when the water table is exceptionally high, the soil is generally dry. The depression and wind gap was a natural route across the Downs for early populations. Fossil records exist from the Pleistocene period (about 4,000,000 years ago). There is evidence of human occupation from the Neolithic period, Iron Age,Volume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Janes Information Services
Janes is a global open-source intelligence company specialising in military, national security, aerospace and transport topics, whose name derives from British author Fred T. Jane. History Jane's Information Group was founded in 1898 by Fred T. Jane, who had begun sketching ships as an enthusiast naval artist while living in Portsmouth. This gradually developed into an encyclopedic knowledge, culminating in the publishing of ''All the World's Fighting Ships'' (1898). The company then gradually branched out into other areas of military expertise. The books and trade magazines published by the company are often considered the ''de facto'' public source of information on warfare and transportation systems. Based in Greater London for most of its existence, the group was owned by the Thomson Corporation, the Woodbridge Company, then IHS Markit, before being acquired by Montagu Private Equity in 2019. In March 2022, Janes acquired Washington, D.C.-based RWR Advisory Group. Descr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solid-fuel Rocket
A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses Rocket propellant#Solid chemical propellants, solid propellants (fuel/oxidizer). The earliest rockets were solid-fuel rockets powered by gunpowder. The inception of gunpowder rockets in warfare can be credited to the ancient Chinese, and in the 13th century, the Mongols played a pivotal role in facilitating their westward adoption. All rockets used some form of solid or powdered propellant until the 20th century, when liquid-propellant rockets offered more efficient and controllable alternatives. Because of their simplicity and reliability, solid rockets are still used today in military armaments worldwide, model rockets, solid rocket boosters and on larger applications. Since solid-fuel rockets can remain in storage for an extended period without much propellant degradation, and since they almost always launch reliably, they have been frequently used in military applications such as missiles. ...
