An electronic warfare expendables dispenser is part of the suite of electronic warfare devices aboard a protected aircraft, ship, or land vehicle.
These expendables include passive radar-reflecting chaff, infrared countermeasures (e.g., flares to confuse heat-seeking missile guidance. They have been expanded to active devices such disposable radar jammers.
In addition to active and passive countermeasures, expendables now include sensors for both electronic support, electronic warfare, and other intelligence functions such as chemical weapon detection using materials MASINT. In addition to the truly expendable items usually released as cartridges, a modern dispenser system will control towed decoys that lure radar- and infrared-guided missiles that avoid the other countermeasures.
In shipboard applications, the expendables may include acoustic decoys to defend against submarines and torpedoes. Land warfare vehicles may use expendable smoke cartridges to obscure them against visually guided weapons, although more modern thermal imagers are not fooled by conventional smoke.
