Abstract: This novel axisymmetric revolved arc explosively formed projectile (REFP) shaped charge design will produce a projectile that is greater than ? the diameter of the device forms a hole larger than the device diameter and removes all of the target material within the hole diameter. The precision of the circular simultaneous initiation of the HE billet is accomplished by the use of a novel Circular Precision Initiation Coupler (CPIC). This CPIC uses a single point initiation to create a simultaneous peripheral detonation of the HE billet that collapses and drives the revolved liner into a large diameter double wall hollow cylindrical explosively formed projectile.
