Abstract
An active countermeasure for military rotorcraft against a heat-seeking missile threat involves one or more telescoping booms or poles that are articulated at their proximal end to the fuselage of the rotorcraft and have an IR-radiating decoy mounted on their distal tip. When a missile launch is detected the missile flight path is computed and one or more of the booms are extended and swung out to place the decoy on the shot line of the missile. The decoy is then switched on and lures the missile away from the vulnerable components of the craft, such as the engine, rotors, and fuselage so as to cause a miss or failing that a detonation away from the rotorcraft. The countermeasures are stored compactly against or within the tail when not deployed.
