Abstract:
1. A munition, comprising: a warhead including a fuze well and a warhead explosive around the fuze well; a booster including a booster explosive placed inside the fuze well, said fuze well providing a barrier between the booster explosive and warhead explosive; a fuze behind the booster inside the fuze well that detonates the booster explosive creating a pressure wave with a peak pressure, said pressure wave having a forward axial component and a radial component; and a booster lens having a surface, said booster lens positioned in the fuze well to re-direct a portion of the radial component of the pressure wave off of the lens surface in the axial direction to concentrate the pressure wave into a lobe in a predetermined direction with increased peak pressure to penetrate the barrier provided by the fuze well and directly detonate the warhead explosive approximately axially from the booster.
