A flechette has a forward body () containing its center of gravity which is connected to a tail section (). The tail section has a pair of fins (A,B) 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.

Two-fin stackable flechette having two-piece construction

A flechette has a forward section or body () containing its center of gravity. A quill () is connected to the forward section and is integrally connected to a pair of fins (A,B) each having a longitudinal angle and a radial angle. When the two fins are viewed from the aft of the flechette, the pair of fins demonstrate an S-shaped orientation. The size, shape and orientation of the fins provide aerodynamic stability to the flechette while allowing the flechette to be stacked with like-shaped flechettes in rows and columns or in a radial, circular arrangement. When stacked in rows and columns or in a circular arrangement, each flechette has its nose oriented in the same forward direction.
