AIM-9L
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-aligned air forces. The Soviet K-13 (AA-2 'Atoll'), a 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 saw extensive use during the Vietnam War but had a low success rate. This led to all-aspect capabilities i ...

Air-to-air Missile
The newest and the oldest member of Rafael's Python family of AAM for comparisons, Python-5 (displayed lower-front) and Shafrir-1 (upper-back) An air-to-air missile (AAM) is a missile fired from an aircraft for the purpose of destroying another aircraft. AAMs are typically powered by one or more rocket motors, usually solid fueled but sometimes liquid fueled. Ramjet engines, as used on the Meteor, are emerging as propulsion that will enable future medium-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 less than 16 km 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 L ...

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 flares beh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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] |
Falklands War
The Falklands War ( es, link=no, Guerra de las Malvinas) was a ten-week undeclared war between Argentina and the United Kingdom in 1982 over two British dependent territories in the South Atlantic: the Falkland Islands and its territorial dependency, South Georgia and the South Sandwich Islands. The conflict began on 2 April, when Argentina invaded and occupied the Falkland Islands, followed by the invasion of South Georgia the next day. On 5 April, the British government dispatched a naval task force to engage the Argentine Navy and Air Force before making an amphibious assault on the islands. The conflict lasted 74 days and ended with an Argentine surrender on 14 June, returning the islands to British control. In total, 649 Argentine military personnel, 255 British military personnel, and three Falkland Islanders were killed during the hostilities. The conflict was a major episode in the protracted dispute over the territories' sovereignt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

AGM-122 Sidearm
The AGM-122 Sidearm was an American air-to-surface anti-radar missile produced between 1986 and 1990. While not as capable as newer anti-radiation missiles, they were cheaper and lighter in weight allowing more versatile deployment. Development The AGM-122 Sidearm was produced by the re-manufacture of AIM-9C missiles that had been taken out of service. The AIM-9C was a semi-active radar homing variant of the Sidewinder, developed for the US Navy's Vought F-8 Crusader, but used for only a limited period of time. Conceived and developed at China Lake NAWS, the Sidearm was first tested in 1981. In 1984, Motorola was issued a contract to convert and upgrade AIM-9Cs to the AGM-122A standard. A total of about 700 units were produced between 1986 and 1990. Existing stocks of Sidearm have been depleted, and the missile is no longer in service. Proposals for new-build missiles, under the designation AGM-122B, have not been proceeded with to date. The AGM-122 was less capable than newe ...

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 ...
