The invention represents a novel system for controlling the yield of an explosive charge that enables the explosive yield to be selected or decreased from full-yield detonation incrementally down to low-yield detonation using a continuous linear shaped charge jet spiraled around the main charge explosive and deflagrating a selected portion of the main charge explosive. The spiral linear shaped charge jet initiation system activates and projects a liner in a radial direction across a diameter of the main charge explosive in a spiral around its axis at a preselected deflagration velocity toward a main-charge detonation shock front reducing the main charge explosive.

What is claimed is: 1. A system for controlling a yield of an explosive charge comprising:a charge case wall;a main charge explosive within said charge case wall;a double-sided spiral linear shaped charge jet mounted to said charge case wall comprising:a deflagration liner coiled around said main charge explosive;a case cutting liner positioned to shoot toward said main charge case;a time variable spiral linear shaped charge jet initiation system connected to said spiral linear shaped charge jet at one end of said charge case wall; anda main charge explosive detonation system at a second end of said charge case, said second end in opposing alignment to said first end;said spiral linear shaped charge jet initiation system activated and projecting said deflagration liner in a radial direction across a diameter of said main charge explosive in a spiral around its axis at a preselected deflagration velocity and projecting said case cutting liner toward said main charge case for cutting said charge case wall and venting deflagration gas products, said spiral linear shaped charge jet advancing toward a main-charge detonation shock front thereby reducing said explosive yield by an amount proportional to the volume of explosive deflagrated at a preselected time when the detonated shock front reaches a deflagration interface.
