Linear shaped charge system

A linear charge system for applying a destructive linear explosive blast to a barrier structure;

• said system comprising a charge carrier and a linear explosive charge assembled within said charge carrier;
• said linear explosive charge adapted to effect a directed linear explosive blast for the penetration of a said barrier in which a tamping fluid forms at least a portion of a penetrating agent, and wherein said charge carrier is comprised of an elongate body of hollow section polymeric material;
• said elongate body provided with a sealing end cap at a first end and a filler end cap at a second end;
• said filler end cap provided with an aperture and closure means adapted to allow the filling of said body with said tamping fluid, and wherein the internal walls of said elongate body are coated with a gelling agent adapted to modify said tamping fluid into a tamping gel when said fluid is added to said elongate body.
