Abstract: A reaction container has contains an amount of a water reactive material and a volume of water within the confined space of its interior. The water reactive material, which contains aluminum, is formed as two separate and spaced apart portions. The water is located between the two portions of the water reactive material. A detonation mechanism, which is configured to mix the amount of water reactive material and the volume of water, is provided in communication with each portion of the water reactive material. The volume of water and the aluminum in the water reactive material are stoichiometrically balanced.

Abstract: An apparatus and method for selectively varying the yield of an explosive device is provided. The apparatus generally comprises a main charge that may selectively be consumed and/or detonated to achieve the selected yield ranging from about 0% to about 100%.

Abstract: A method and apparatus for enhancing explosive yield is provided. The apparatus generally includes an energetic charge operatively associated with a guide. The guide is operatively associated with a reactive material. According to an aspect of the method, the energetic charge is activated to produce a shockwave to impact a reactive material. The shockwave is focused by the guide to impact the reactive material. Impacting the reactive material releases energy in the reactive material to enhance the yield of the energetic charge.
