AIM-9 Sidewinder
The AIM-9 Sidewinder (where "AIM" stands for "Air Intercept Missile") is a short-range air-to-air missile which entered service with the US Navy in 1956 and subsequently was adopted by the US Air Force in 1964. Since then the Sidewinder has proved to be an enduring international success, and its latest variants remain standard equipment in most Western world, Western-aligned air forces. The Soviet Union, Soviet K-13 (missile), K-13 (AA-2 'Atoll'), a Reverse engineering#Reverse engineering for military applications, reverse-engineered copy of the AIM-9B, was also widely adopted by a number of nations. Low-level development started in the late 1940s, emerging in the early 1950s as a guidance system for the modular Zuni rocket. This modularity allowed for the introduction of newer seekers and rocket motors, including the AIM-9C variant, which used semi-active radar homing and served as the basis of the AGM-122 Sidearm anti-radar missile. Originally a tail-chasing system, early models ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrared Homing
Infrared homing is a passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it seamlessly. Missiles which use infrared seeking are often referred to as "heat-seekers" since infrared is radiated strongly by hot bodies. Many objects such as people, vehicle engines and aircraft generate and emit heat and so are especially visible in the infrared wavelengths of light compared to objects in the background. Infrared seekers are passive devices, which, unlike radar, provide no indication that they are tracking a target. That makes them suitable for sneak attacks during visual encounters or over longer ranges when they are used with a forward looking infrared or similar cuing system. Heat-seekers are extremely effective: 90% of all United States air combat losses over the past 25 years have been caused by infrared-homing missiles. They are, however, subject to a number of simple countermeasures, most notably by dropping flare ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raytheon Company
The Raytheon Company was a major U.S. defense contractor and industrial corporation with manufacturing concentrations in weapons and military and commercial electronics.

More than 90% of Raytheon's revenues were obtained from military contracts and, as of 2012, it was the fifth-largest military contractor in the world. , it was the third largest defense contractor in the United States by defense revenue. In 2003, Raytheon's headquarters moved from Lexington, Massachusetts, to Waltham, Massachusetts. The company had pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-active Radar Homing
Semi-active radar homing (SARH) is a common type of missile guidance system, perhaps the most common type for longer-range air-to-air and surface-to-air missile systems. The name refers to the fact that the missile itself is only a passive detector of a radar signal— provided by an external ("offboard") source—as it reflects off the target (in contrast to active radar homing, which uses an active radar transceiver). Semi-active missile systems use bistatic continuous-wave radar. The NATO brevity code for a semi-active radar homing missile launch is Fox One. Concept The basic concept of SARH is that since almost all detection and tracking systems consist of a radar system, duplicating this hardware on the missile itself is redundant. The weight of a transmitter reduces the range of any flying object, so passive systems have greater reach. In addition, the resolution of a radar is strongly related to the physical size of the antenna, and in the small nose cone of a miss ...

Fox (code Word)
Fox is a brevity code used by NATO pilots to signal the simulated or actual release of an 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. "Fox" is short for "foxtrot", the NATO phonetic designation for the letter "F", which is short for "fire". The radio call 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. 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). ;Fox one: Indicates launch of a semi-active radar-guided missile (such as the AIM-7 Sparrow). ;Fox two: Indicates launch of an infrared-guided missile (such as the AIM-9 Sidewinder). ;Fox three: Indicates launch of an active radar-guided missile (su ...

NATO
The North Atlantic Treaty Organization (NATO, ; french: Organisation du traité de l'Atlantique nord, ), also called the North Atlantic Alliance, is an intergovernmental military alliance between 30 member states – 28 European and two North American. Established in the aftermath of World War II, the organization implemented the North Atlantic Treaty, signed in Washington, D.C., on 4 April 1949. NATO is a collective security system: its independent member states agree to defend each other against attacks by third parties. During the Cold War, NATO operated as a check on the perceived threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa. The organization's motto is '' animus in consulendo liber'' (Latin for "a mind unfettered in deliberation"). NATO's main headquarters are located in Brussels, Belgium, while ...

SRAAM
The Short Range Air-to-Air Missile, or SRAAM for short, initially known as Taildog, was an experimental British infrared homing ("heat seeking") air-to-air missile, developed between 1968 and 1980 by Hawker Siddeley Dynamics. It was designed to be very manoevrable for use at short range in a dogfight situation. SRAAM was unusual in that it was launched from a launch tube instead of being attached to a launch rail, allowing two to be carried on a single mounting point. Although initially intended to replace the AIM-9 Sidewinder, it was downgraded to a technology demonstrator program in 1974. Between 1974 and 1977, several SRAAM missiles were launched in tests. In 1980, the knowledge gained from the SRAAM project was used in the ASRAAM missile project. History Background Early infrared homing missiles had two limitations that made them difficult to use in combat situations. The first was that the seeker was relatively insensitive and required large, hot sources to reliably track a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AIM-95 Agile
The AIM-95 Agile was an air-to-air missile developed by the United States. It was developed by the US Navy to equip the F-14 Tomcat, replacing the AIM-9 Sidewinder. Around the same time, the US Air Force was designing the AIM-82 to equip their F-15 Eagle, and later dropped their efforts to join the Agile program. In the end, newer versions of Sidewinder would close the performance gap so much that the Agile program was canceled. Overview Background Early infrared homing missiles had two limitations that made them difficult to use in combat situations. The first was that the seeker was relatively insensitive and required large, hot sources to reliably track a target. In practice, this meant the engine of the enemy aircraft had to remain visible to the missile through the shot. The other was that the seeker had a limited field of view (FOV), meaning it could only see the target if it was in front of the missile. These limitations were made clear during the Vietnam War, when early mis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Mole Cricket 19
Operation Mole Cricket 19 ( he , מבצע ערצב-19, ''Mivtza ʻArtzav Tsha-Esreh'') was a suppression of enemy air defenses (SEAD) campaign launched by the Israeli Air Force (IAF) against Syrian targets on June 9, 1982, at the outset of the 1982 Lebanon War. The operation was the first time in history that a Western-equipped air force successfully destroyed a Soviet-built surface-to-air missile (SAM) network. It also became one of the biggest air battles since World War II,Nordeen (1990), p. 175 and the biggest since the Korean War.Cohen (1990), p. 615 The result was a decisive Israeli victory, leading to the colloquial name the "Bekaa Valley Turkey Shoot". The IAF began working on a SAM suppression operation at the end of the Yom Kippur War. Rising tensions between Israel and Syria over Lebanon escalated in the early 1980s and culminated in Syria deploying SAM batteries in the Beqaa Valley. On June 6, 1982, Israel invaded Lebanon, and on the third day of the war, with clashes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
