Abstract
A flechette has a forward section or body (12) containing its center of gravity. A quill (10) is connected to the forward section and is integrally connected to a pair of fins (15A, 15B) 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.
