Abstract

A projectile having a leading section and a trailing section coupled together to define a structure for delivering a plurality of flechettes. The trailing section includes aerodynamic control surfaces that are deployable to apply an aerodynamic braking force to the trailing section to separate the trailing section from the leading section. The flechettes surround an explosive charge in the leading section such that initiation of the explosive charge outwardly disperses the flechettes after the leading section and the trailing section have separated. The control surfaces optionally also may impart spin to the projectile to assist in dispersing the flechettes. Thus, aerodynamic force is employed to assist in removing the flechettes from their confining structure in the projectile before dispersing them.
