Abstract
A projectile launch package for use in electromagnetic launching systems is provided with separable armature and projectile assemblies. The armature assembly includes a conductive element which initially conducts accelerating current. After a certain time, the conductive element fuses, thereby forming a plasma which further accelerates the projectile assembly. Following the plasma initiation, the armature assembly is expelled from the launcher under its own momentum.
