An armature for use in electromagnetic projectile launchers is provided with a plurality of modular conductive fiber bundles which are arranged in a rectangular array and attached to an insulating armature support structure. The conductive fibers extend across the launcher bore and are sized to provide an interference fit between a pair of generally parallel conductive launcher rails. Each fiber bundle includes a rectangular central sheath and a pair of peripheral rectangular sheets positioned on opposite sides of the central sheath. The axis of each peripheral sheet is positioned at an angle with respect to the axis of the central sheath.

An armature assembly for conducting very large DC current between two parallel, electrically conductive rails while being driven along a gap between the rails under the influence of electromanetic forces generated by the flow of said very large DC current, said armature assembly comprising: an insulating armature support member capable of being sized to form a clearance fit between said rails; a plurality of conductive fibers, each having a length greater than the width of said support member; said conductive fibers being divided into a plurality of fiber bundles where each bundle includes a first rectangular sheath having an axis and encompassing a first portion of a first group of said conductive fibers and second and third rectangular sheaths, respectively encompassing second and third portions of said first group of said conductive fibers wherein said second and third sheathes are positioned on opposite sides of said first sheath and are positioned at a preselected angle with respect to the axis of said first sheath; and means for attaching said fiber bundles to said support member.
