ABSTRACT:
A sub-munition warhead contains several flechettes arranged in a circumferential pattern. A canister with a length less than that of the flechettes surrounds the rear ends of the flechettes. A frangible fairing extends from the canister to a small diameter nose cone. An indexer adjacent the nose cone and a sabot for each flechette retain the flechettes in position on a piston joining the canister and the nose cone. The warhead is normally launched with a rocket motor. It is spun so that on burnout, the warhead is travelling at high speed and spinning. On burnout, a fuze is ignited and the piston is propelled down the canister. This drives the flechettes forwardly, rupturing the fairing and allowing the flechettes to separate for independent flight to a target.
