    en.wikipedia.org/wiki/Flare_(countermeasure)

    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.

  3. Missile approach warning system - Wikipedia

    en.wikipedia.org/wiki/Missile_approach_warning...

    Very low IR transmission through liquid water and ice, which precludes all-weather operation. Even a few tens of micrometers of water on the lens, or in the atmosphere between the threat and the sensor, is sufficient to effectively blind both MWIR and LWIR sensors. Must compete with massive amounts of natural (sun) and man-made IR clutter.

    The dominant aerial flare at the time was the Mk 24 Mod 0, developed by the US Navy. Reliability of the units, however, were in question, as was availability. Perhaps of greater concern was existing test data in 1966 that suggested pilot disorientation and flare placement were serious issues.

    On the left, the main IR sensor (100 km range), on the right a TV/IR identification sensor with laser rangefinder (40 km range) An electro-optical targeting system (EOTS), is a system employed to track and locate targets in aerial warfare. [1] It can use charge-coupled device TV cameras, laser rangefinders and laser designators.

    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 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 ...

    A flare, also sometimes called a fusée, fusee, or bengala, [1] [2] bengalo [3] in several European countries, is a type of pyrotechnic that produces a bright light or intense heat without an explosion. Flares are used for distress signaling, illumination, or defensive countermeasures in civilian and military applications. Flares may be ground ...

    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 ...
