Abstract

A projectile (52) for use with an electromagnetic launcher has an armature (82) for conducting current between conducting rails (66, 68) of the launcher. The armature has a plurality of curved trailing arms. During launch of the projectile, the current flowing through the trailing arms (84) of the armature, interacts with the magnetic fields generated by current flowing through the rails. The interaction causes the armature, and thus the projectile, to spin about its longitudinal axis.
