Abstract
A flechette has a forward body (20) containing its center of gravity which is connected to a tail section (24). The tail section has a pair of fins (24A, 24B) each having a preselected longitudinal angle and radial angle. When the two fins are viewed from the aft of the flechette, the pair of fins demonstrate a S-shaped orientation. The size, shape and orientation of the pair of fins provide aerodynamic stability to the flechette while allowing the flechette to be stacked with like-shaped flechettes. The two-piece assembly of the flechette easily accommodates the use of different density materials for the respective pieces.
