Abstract: An infra-red emitting decoy flare capable of diverting an incoming missile equipped with a counter-countermeasures system away from an intended target consisting of a primer flare (2), a spectral flare (4) and a means for igniting the primer flare (22, 30), all contained within a flare casing (6). The primer flare (2) is formed from a fast burning pyrotechnic composition and is adapted to produce an intense infra-red source of short duration on ignition. The spectral flare (4) is ignited by the burning of the primer flare (2) and is adapted to produce a slower burning composition having a fixed ratio in the intensity of infra-red radiation emitted, when burning, in at least two fixed bands.
