Abstract

A limited range projectile includes pyrotechnic material and reactive material. The pyrotechnic material is ignited at projectile launch. The pyrotechnic material ignites the reactive material. If the projectile reaches a maximum desired range prior to impact with a target, the ignited reactive material transforms the projectile into an aerodynamically unstable object.
