Joint Stand-Off Weapon
The AGM-154 Joint Standoff Weapon (JSOW) is a glide bomb that resulted from a joint venture between the United States Navy and Air Force to deploy a standardized medium range precision guided weapon, especially for engagement of defended targets from outside the range of standard anti-aircraft defenses, thereby increasing aircraft survivability and minimizing friendly losses. The designation of the ''Joint Standoff Weapon'' as an "air-to-ground missile" is a misnomer, as it is an unpowered bomb with guidance avionics, similar to the older GBU-15. Development The JSOW is a fire-and-forget weapon that employs a tightly coupled GPS/INS for navigation, and is capable of day/night and adverse weather operations. The JSOW-C adds an infra-red seeker for terminal guidance. Originally the JSOW was developed by Defense Systems & Electronics division of Texas Instruments. After a first flight, funded by the company in April 1991, a joint program between the US Navy and the US Air Force wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glide Bomb
A glide bomb or stand-off bomb is a standoff weapon with flight control surfaces to give it a flatter, gliding flight path than that of a conventional bomb without such surfaces. This allows it to be released at a distance from the target rather than right over it, allowing a successful attack without the aircraft needing to survive until reaching the target. World War II-era glide bombs like the German Fritz X and Henschel Hs 293 pioneered the use of remote control systems, allowing the controlling aircraft to direct the bomb to a pinpoint target as a pioneering form of precision-guided munition. Modern systems are generally self-guided or semi-automated, using GPS or laser designators to hit their target. The term " glide bombing" does not refer to the use of glide bombs, but a style of shallow-angle dive bombing. Early efforts German designs World War I In October 1914 Wilhelm von Siemens suggested what became known as the Siemens torpedo glider, a wire-guided flying ...

Anti-aircraft
Anti-aircraft warfare, counter-air or air defence forces is the battlespace response to aerial warfare, defined by NATO as "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It includes surface based, subsurface ( submarine launched), and air-based weapon systems, associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defence. NATO refers to airborne air defence as counter-air and naval air defence as anti-aircraft warfare. Missile defence is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. In some countries, such as Britain and Germany during the Second World War, the Soviet Union, and modern NATO and the United States, ground-based air defence and air defence aircraft ...

Foreign Military Sales
The United States Department of Defense's Foreign Military Sales (FMS) program facilitates sales of U.S. arms, defense equipment, defense services, and military training to foreign governments. The purchaser does not deal directly with the defense contractor; instead, the Defense Security Cooperation Agency (DSCA) serves as an intermediary, usually handling procurement, logistics, and delivery, often providing product support, training, and infrastructure construction (such as hangars, runways, utilities, etc.). FMS is carried out with countries that are authorized to participate and is subject to approval based on the mechanism to procure services, a deposit in a U.S. trust fund or appropriate credit, and approval to fund services. On any given day, DSCA is managing “14,000 open foreign military sales cases with 185 countries,” the DSCA director Lieutenant General Charles Hooper explained at the Brookings Institution in June 2019. Some U.S. Air Force (USAF) FMS programs are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Standoff (missile)
Standoff weapons are missiles or bombs which may be launched from a distance sufficient to allow attacking personnel to evade the effect of the weapon or defensive fire from the target area. Typically, they are used against land- and sea-based targets in an offensive operation. The name is derived from their ability to engage the target while standing off outside the range at which the defenders are likely to engage the attacker. Typical stand-off weapons include cruise missiles, glide bombs and short-range ballistic missiles.

Terminal Guidance
In the field of weaponry, terminal guidance refers to any guidance system that is primarily or solely active during the "terminal phase", just before the weapon impacts its target. The term is generally used in reference to missile guidance systems, and specifically to missiles that use more than one guidance system through the missile's flight. Common examples include long-range air-to-air missiles that use semi-active radar homing (SARH) during most of the missile's flight, and then use an infrared seeker or active radar homing once they approach their target. Similar examples include surface-to-air missiles, anti-ballistic missiles, and some anti-tank missiles. Concept Radar beams are cone-shaped, spreading out from the diameter of the antenna at a characteristic angle that is a function of the size of the antenna and its wavelength. This means that as one moves away from the radar, its accuracy continues to degrade while the signal grows weaker. This makes it difficult to use ...

Infra-red
Infrared (IR), sometimes called infrared light, is electromagnetic radiation (EMR) with wavelengths longer than those of visible light. It is therefore invisible to the human eye. IR is generally understood to encompass wavelengths from around 1 millimeter (300 GHz) to the nominal red edge of the visible spectrum, around 700 nanometers (430 THz). Longer IR wavelengths (30 μm-100 μm) are sometimes included as part of the terahertz radiation range. Almost all black-body radiation from objects near room temperature is at infrared wavelengths. As a form of electromagnetic radiation, IR propagates energy and momentum, exerts radiation pressure, and has properties corresponding to both those of a wave and of a particle, the photon. It was long known that fires emit invisible heat; in 1681 the pioneering experimenter Edme Mariotte showed that glass, though transparent to sunlight, obstructed radiant heat. In 1800 the astronomer Sir William Herschel discovered tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GPS/INS
GPS/INS is the use of GPS satellite signals to correct or calibrate a solution from an inertial navigation system (INS). The method is applicable for any GNSS/INS system. Overview GPS/INS method The GPS gives an absolute drift-free position value that can be used to reset the INS solution or can be blended with it by use of a mathematical algorithm, such as a Kalman filter. The angular orientation of the unit can be inferred from the series of position updates from the GPS. The change in the error in position relative to the GPS can be used to estimate the unknown angle error. The benefits of using GPS with an INS are that the INS may be calibrated by the GPS signals and that the INS can provide position and angle updates at a quicker rate than GPS. For high dynamic vehicles, such as missiles and aircraft, INS fills in the gaps between GPS positions. Additionally, GPS may lose its signal and the INS can continue to compute the position and angle during the period of lost GPS sig ...

Fire-and-forget
Fire-and-forget is a type of missile guidance which does not require further external intervention after launch such as illumination of the target or wire guidance, and can hit its target without the launcher being in line-of-sight of the target. This is an important property for a guided weapon to have, since a person or vehicle that lingers near the target to guide the missile (using, for instance, a laser designator) is vulnerable to attack and unable to carry out other tasks. Generally, information about the target is programmed into the missile just prior to launch. This can include coordinates, radar measurements (including velocity), or an infrared image of the target. After it is fired, the missile guides itself by some combination of gyroscopes and accelerometers, GPS, onboard active radar homing, and infrared homing optics. Some systems offer the option of either continued input from the launch platform or fire-and-forget. Fire-and-forget missiles can be vulnerable ...
