R-77 (missile)
The Vympel NPO R-77 missile (NATO reporting name: AA-12 Adder) is a Russian active radar homing beyond-visual-range air-to-air missile. It is also known by its export designation RVV-AE. It is the Russian counterpart to the American AIM-120 AMRAAM missile. The R-77 was marked by a severely protracted development. Work began in the 1980s, but was not completed before the Soviet Union fell. For many years, only the RVV-AE model was produced for export customers. Production was further disrupted when the Russian invasion of Ukraine resulted in a Ukrainian arms embargo against Russia, severing supply chains. The Russian Air Force finally entered the R-77-1 (AA-12B) into service in 2015. It was subsequently deployed by Su-35S fighters in Syria on combat air patrols. The export model of the R-77-1 is called RVV-SD. Development Work on the R-77 began in 1982. It represented Russia's first multi-purpose missile for tactical and strategic aircraft for fire-and-forget use against ai ...

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 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 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 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, and in the case of a mobile launching platform ...

Beyond-visual-range Missile
A beyond-visual-range missile (BVR) is an air-to-air missile (BVRAAM) that is capable of engaging at ranges of or beyond. This range has been achieved using dual pulse rocket motors or booster rocket motor and ramjet sustainer motor. 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 of BVR missiles use a combination of semi-active and active radar. The first such missiles were relatively simple beam riding designs. The Sparrow 1 mounted on the US Navy's Skyknight became the first operational BVR missile in 1954. These primitive BVR missiles were soon replaced by missiles using semi-active radar homing ( ...

Cruise Missiles
A cruise missile is a guided missile used against terrestrial or naval targets that remains in the atmosphere and flies the major portion of its flight path at approximately constant speed. Cruise missiles are designed to deliver a large warhead over long distances with high precision. Modern cruise missiles are capable of travelling at high subsonic, supersonic, or hypersonic speeds, are self-navigating, and are able to fly on a non-ballistic, extremely low-altitude trajectory. History The idea of an "aerial torpedo" was shown in the British 1909 film ''The Airship Destroyer'' in which flying torpedoes controlled wirelessly are used to bring down airships bombing London. In 1916, the American aviator Lawrence Sperry built and patented an "aerial torpedo", the Hewitt-Sperry Automatic Airplane, a small biplane carrying a TNT charge, a Sperry autopilot and a barometric altitude control. Inspired by the experiments, the United States Army developed a similar flying bomb called th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proximity Fuze
A proximity fuze (or fuse) is a Fuze (munitions), fuze that detonates an Explosive material, explosive device automatically when the distance to the target becomes smaller than a predetermined value. Proximity fuzes are designed for targets such as planes, missiles, ships at sea, and ground forces. They provide a more sophisticated trigger mechanism than the common contact fuze or timed fuze. It is estimated that it increases the lethality by 5 to 10 times, compared to these other fuzes. Background Before the invention of the proximity fuze, detonation was induced by direct contact, a timer set at launch or an altimeter. All of these earlier methods have disadvantages. The probability of a direct hit on a small moving target is low; a shell that just misses the target will not explode. A time- or height-triggered fuze requires good prediction by the gunner and accurate timing by the fuze. If either is wrong, then even accurately aimed shells may explode harmlessly before reaching ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MIM-104 Patriot
The MIM-104 Patriot is a surface-to-air missile (SAM) system, the primary of its kind used by the United States Army and several allied states. It is manufactured by the U.S. defense contractor Raytheon and derives its name from the radar component of the weapon system. The AN/MPQ-53 at the heart of the system is known as the " Phased Array Tracking Radar to Intercept on Target", or PATRIOT. The Patriot system replaced the Nike Hercules system as the U.S. Army's primary High to Medium Air Defense (HIMAD) system and replaced the MIM-23 Hawk system as the U.S. Army's medium tactical air defense system. In addition to these roles, Patriot has been given the function of the U.S. Army's anti-ballistic missile (ABM) system, which is now Patriot's primary mission. The system is expected to stay fielded until at least 2040. Patriot uses an advanced aerial interceptor missile and high-performance radar systems. Patriot was developed at Redstone Arsenal in Huntsville, Alabama, which ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AIM-54 Phoenix
The AIM-54 Phoenix is an American radar-guided, long-range air-to-air missile (AAM), carried in clusters of up to six missiles on the Grumman F-14 Tomcat, its only operational launch platform. The Phoenix was the United States' only long-range air-to-air missile. The combination of Phoenix missile and the Tomcat's AN/AWG-9 guidance radar meant that it was the first aerial weapons system that could simultaneously engage multiple targets. Due to its active radar tracking, the brevity code " Fox Three" was used when firing the AIM-54. Both the missile and the aircraft were used by Iran and the United States Navy. In US service both are now retired, the AIM-54 Phoenix in 2004 and the F-14 in 2006. They were replaced by the shorter-range AIM-120 AMRAAM, employed on the F/A-18 Hornet and F/A-18E/F Super Hornet—in its AIM-120D version, the latest version of the AMRAAM just matches the Phoenix's maximum range. The AIM-54 has been used in 62 air-to-air strikes, all by Iran during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Combat Air Patrol
Combat air patrol (CAP) is a type of flying mission for fighter aircraft. A combat air patrol is an aircraft patrol provided over an objective area, over the force protected, over the critical area of a combat zone, or over an air defense area, for the purpose of intercepting and destroying hostile aircraft before they reach their target. Combat air patrols apply to both overland and overwater operations, protecting other aircraft, fixed and mobile sites on land, or ships at sea. Known by the acronym CAP, it typically entails fighters flying a tactical pattern around or screening a defended target, while looking for incoming attackers. Effective CAP patterns may include aircraft positioned at both high and low altitudes, in order to shorten response times when an attack is detected. Modern CAPs are either GCI or AWACS-controlled to provide maximum early warning for defensive reaction. The first CAPs were characteristic of aircraft carrier operations, where CAPs were flown to ...

Supply Chain
In commerce, a supply chain is a network of facilities that procure raw materials, transform them into intermediate goods and then final products to customers through a distribution system. It refers to the network of organizations, people, activities, information, and resources involved in delivering a product or service to a consumer. Supply chain activities involve the transformation of natural resources, raw materials, and components into a finished product and delivering the same to the end customer. In sophisticated supply chain systems, used products may re-enter the supply chain at any point where residual value is recyclable. Supply chains link value chains. Suppliers in a supply chain are often ranked by "tier", with first-tier suppliers supplying directly to the client, second-tier suppliers supplying to the first tier, and so on. Overview A typical supply chain begins with the ecological, biological, and political regulation of natural resources, followed by the ...

Arms Embargo
An arms embargo is a restriction or a set of sanctions that applies either solely to weaponry or also to "dual-use technology." An arms embargo may serve one or more purposes: * to signal disapproval of the behavior of a certain actor * to maintain neutrality in an ongoing conflict * as a peace mechanism that is part of a peace process to resolve an armed conflict * to limit the ability of an actor to inflict violence on others * to weaken a country's military capabilities before a foreign intervention Historical examples Argentina US President Jimmy Carter imposed an arms embargo on the military government of Argentina in 1977 in response to human rights abuses. An arms embargo was put in place, along with other economic sanctions by the European Economic Community (EEC), within a week of the 1982 invasion of the Falkland Islands by Argentina, two British dependent territories in the South Atlantic. The European nations ended the embargo after the end of the ensuing Falklands W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
