Countermeasure decoy system intended to be mounted on an aircraft

Counter-measure decoy system designed to be installed on an aircraft and of the type comprising:

• counter-measure projectiles (6);
• at least one tube (5) for receiving said counter-measure projectiles in series and for the successive controllable launch of said projectiles;
• and
• a control mechanism (7) for advancing said projectiles inside said tube, wherein:
• said counter-measure projectiles (6) respectively comprise dimensionally identical external cylindrical bodies (80), housed inside said tube and each having a deployable-tail-fin aerodynamic stabilisation device (9), which tail-fins assume a folded position inside the body when said projectile is inside said tube, and a deployed position outside of said tube, and
• said system comprises a projectile ejection module (8), with an axial passage (12), fixedly arranged in the extension of said tube, opposite said advance mechanism, and successively containing, after said control mechanism, said projectile (6) to be ejected from said tube by a controllable ejection device (25) connected to said module.
