A flare or decoy flare is an aerial infrared countermeasure used by an aircraft to counter an infrared homing ("heat-seeking") surface-to-air missile or air-to-air missile. Flares are commonly composed of a pyrotechnic composition based on magnesium or another hot-burning metal, with burning temperature equal to or hotter than engine exhaust.
The ALE-47 is integrated with the aircraft's radar warning receivers, missile warning receivers and other electronic warfare sensors.When the aircraft's sensors detect a threat, the countermeasure dispenser system automatically launches radiofrequency and infrared countermeasures at the optimum time to defeat incoming missiles.
A Royal Air Force Boeing E-3 Sentry over North Yorkshire. An airborne early warning and control (AEW&C) system is an airborne radar early warning system designed to detect aircraft, ships, vehicles, missiles and other incoming projectiles at long ranges, as well as performing command and control of the battlespace in aerial engagements by informing and directing friendly fighter and attack ...
On March 16, 1955, the U.S. Air Force had ordered the development of an advanced reconnaissance satellite to provide continuous surveillance of “preselected areas of the Earth” in order “to determine the status of a potential enemy’s war-making capability.” [2] The result of this order was the creation of a then-secret USAF program known as WS-117L, which controlled the development ...
The most common method of infrared countermeasure is deploying flares, as the heat produced by the flares creates hundreds of targets for the missile. Conventional man-portable air defense systems -launched missiles include an infrared sensor that is sensitive to heat, for example the heat emitted from an aircraft engine. The missile is ...
Alert or notification of an emergency in progress; Position or location (or localization or pinpointing) of the party in distress. For example, a single aerial flare alerts observers to the existence of a vessel in distress somewhere in the general direction of the flare sighting on the horizon but extinguishes within one minute or less. A hand ...
An airborne sensor operator (aerial sensor operator, ASO, Aerial Remote Sensing Data Acquisition Specialist, Aerial Payload Operator, Police Tactical Flight Officer, Tactical Coordinator etc.) is the functional profession of gathering information from an airborne platform (Manned or Unmanned) and/or oversee mission management systems for academic, commercial, public safety or military remote ...
A modern LUU-2B flare at 1,000 feet altitude illuminates the ground at 5 lux in a radius of 1500 feet. Burn time is 4–5 minutes. The flare is 36 inches long, 4.9 inches in diameter, and weighs about 30 pounds. A similar design called LUU-19B can provide covert illumination in the near-infrared (IR) spectrum with virtually no visual signature.
