Electronic Countermeasures
An electronic countermeasure (ECM) is an electrical or electronic device designed to countermeasure, trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of Radar jamming, jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile guidance, missile terminal homers. History The first example of electronic countermeasures being a ...

2 (two) is a number, numeral (linguistics), numeral and numerical digit, digit. It is the natural number following 1 and preceding 3. It is the smallest and the only even prime number. Because it forms the basis of a Dualistic cosmology, duality, it has Religion, religious and Spirituality, spiritual significance in many Culture, cultures. Mathematics The number 2 is the second natural number after 1. Each natural number, including 2, is constructed by succession, that is, by adding 1 to the previous natural number. 2 is the smallest and the only even prime number, and the first Ramanujan prime. It is also the first superior highly composite number, and the first colossally abundant number. An integer is determined to be Parity (mathematics), even if it is Division (mathematics), divisible by two. When written in base 10, all Multiple (mathematics), multiples of 2 will end in 0, 2, 4, 6, or 8; more generally, in any even base, even numbers will end with an even digit. A dig ...

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 ...

Surface-to-air Missile
A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground or the sea to destroy aircraft or other missiles. It is one type of anti-aircraft warfare, anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles. The first attempt at SAM development took place during World War II, but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during the second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence. T ...

AGM-88 And AIM-9 On Tornado
The AGM-88 HARM (High-speed Anti-Radiation Missile) is a tactical, air-to-surface anti-radiation missile designed to home in on electronic transmissions coming from surface-to-air radar systems. It was originally developed by Texas Instruments as a replacement for the AGM-45 Shrike and AGM-78 Standard ARM system. Production was later taken over by Raytheon Corporation when it purchased the defense production business of Texas Instruments. Description The AGM-88 can detect, attack and destroy a radar antenna or transmitter with minimal aircrew input. The proportional guidance system that homes in on enemy radar emissions has a fixed antenna and seeker head in the missile's nose. A smokeless, solid-propellant, booster-sustainer rocket motor propels the missile at speeds over Mach 2. The HARM was a missile program led by the U.S. Navy, and it was first carried by the A-6E, A-7, and F/A-18A/B aircraft, and then it equipped the EA-6B and EA-18G dedicated electronic attack ...

Chaff (radar Countermeasure)
Chaff, originally called Window or Düppel, is a Radar jamming and deception, radar countermeasure involving the dispersal of thin strips of aluminium, Metallizing, metallized glass fiber, or Metallised film, plastic. Dispersed chaff produces a large radar cross section intended to blind or disrupt radar systems. Modern military forces use chaff to distract Active radar homing, active radar homing missiles from their targets. Military aircraft and warships can be equipped with chaff dispensing systems for self-defense. During its Ballistic missile flight phases#Midcourse, midcourse phase, an intercontinental ballistic missile may release chaff along with its other Penetration aid, penetration aids. Contemporary radar systems can distinguish chaff from legitimate targets by measuring the Doppler shift, Doppler effect; chaff quickly loses speed after leaving an aircraft, and the resulting shift in wavelength of the radar return can be measured. To counter this, a chaff cloud can ...

Israel Air Force
The Israeli Air Force (IAF; , commonly known as , ''Kheil HaAvir'', "Air Corps") operates as the aerial and space warfare branch of the Israel Defense Forces (IDF). It was founded on May 28, 1948, shortly after the Israeli Declaration of Independence. , Aluf Tomer Bar has been serving as the Air Force commander. The Israeli Air Force was established using commandeered or donated civilian aircraft and obsolete and surplus World War II combat aircraft. Eventually, more aircraft were procured, including Boeing B-17s, Bristol Beaufighters, de Havilland Mosquitoes and P-51D Mustangs. The Israeli Air Force played an important part in Operation Kadesh, Israel's part in the 1956 Suez Crisis, dropping paratroopers at the Mitla Pass. On June 5, 1967, the first day of the Six-Day War, the Israeli Air Force performed Operation Focus, debilitating the opposing Arab air forces and attaining air supremacy for the remainder of the war. Shortly after the end of the Six-Day War, Egypt i ...

Operation Orchard
Operation Outside the Box, also known as Operation Orchard, was an Israeli airstrike on a suspected nuclear reactor, referred to as the Al Kibar site (also referred to in IAEA documents as Dair Alzour), in the Deir ez-Zor region of Syria, which occurred just after midnight (local time) on 6 September 2007. The Israeli and U.S. governments did not announce the secret raids for seven months. The White House and Central Intelligence Agency (CIA) subsequently confirmed that American intelligence had also indicated the site was a nuclear facility with a military purpose, though Syria's Assad government denied this. A 2009 International Atomic Energy Agency (IAEA) investigation reported evidence of uranium and graphite and concluded that the site bore features resembling an undeclared nuclear reactor. IAEA was initially unable to confirm or deny the nature of the site because, according to IAEA, Syria failed to provide necessary cooperation with the IAEA investigation. Syria has d ...

Anti-radiation Missile
An anti-radiation missile (ARM) is a missile designed to detect and home in on an enemy radio emission source. Typically, these are designed for use against an enemy radar, although jammers and even radios used for communications can also be targeted in this manner. The earliest known anti-radiation weapon is a variant of the Blohm & Voss BV 246 radar guided bomb.Lepage, Jean-Denis G.G. (2009). Aircraft of the Luftwaffe 1935-1945. McFarland. p. 67. . Home-on-jam As jammers proliferated, a number of existing ARMs such as the AGM-88 HARM was modified to also target jammers as the source of radiation. Jammers also led to the addition of a feature to missiles that usually use a different targeting mode (e.g. active radar homing, semi-active radar homing, GPS), allowing them to switch to an anti-radiation targeting mode when radar deteriorates too much. Some examples are: * JDAM and JDAM-ER, air-to-surface GPS bomb * AMRAAM, active radar homing air-to-air missile * R-77, active ...

Cold War
The Cold War was a period of global Geopolitics, geopolitical rivalry between the United States (US) and the Soviet Union (USSR) and their respective allies, the capitalist Western Bloc and communist Eastern Bloc, which lasted from 1947 until the dissolution of the Soviet Union in 1991. The term ''Cold war (term), cold war'' is used because there was no direct fighting between the two superpowers, though each supported opposing sides in regional conflicts known as proxy wars. In addition to the struggle for ideological and economic influence and an arms race in both conventional and Nuclear arms race, nuclear weapons, the Cold War was expressed through technological rivalries such as the Space Race, espionage, propaganda campaigns, Economic sanctions, embargoes, and sports diplomacy. After the end of World War II in 1945, during which the US and USSR had been allies, the USSR installed satellite state, satellite governments in its occupied territories in Eastern Europe and N ...

Night Fighter
A night fighter (later known as all-weather fighter or all-weather interceptor post-Second World War) is a largely historical term for a fighter aircraft, fighter or interceptor aircraft adapted or designed for effective use at night, during periods of adverse meteorological conditions, or in otherwise poor visibility. Such designs were in direct contrast to day fighter, day fighters: fighters and interceptors designed primarily for use during the day or during good weather. The concept of the night fighter was developed and experimented with during the First World War but would not see widespread use until WWII. The term would be supplanted by “all-weather fighter/interceptor” post-WWII, with advancements in various technologies permitting the use of such aircraft in virtually all conditions. During the Second World War, night fighters were either purpose-built night fighter designs, or more commonly, heavy fighters or light bombers adapted for the mission, often employing ...
