ABSTRACT:
An ordnance or munition casing is described which comprises a hollow outer casing having a shock attenuating inner liner made from successive layers of material of inwardly decreasing acoustic impedance. The inner liner reduces the sensitivity of the munition to sympathetic detonation and cookoff. Also described is an attenuation barrier made from a layer or layers of less detonation sensitive explosive material. The layers of less detonation sensitive material are preferably arranged in successive layers of outwardly decreasing detonation sensitivity. The same layers may combine sequenced acoustic impedance and detonation sensitivity. The layers may be made of material compounded with flaked or granular materials to provide preselected acoustic impedances. A coating for desensitizing the outer surface layer of a main explosive charge is also disclosed.
