Abstract: An explosive device comprising:(1) a metal liner composed of a metal selected from the group consisting of luminum, magnesium, copper, and brass, the liner enclosing a chamber;(2) a liquid contain in the chamber;(3) a layer of pyrotechnic material surrounding the outside of the liner, the pyrotechnic material composed of a mixture of powders of(a) nickel;(b) metal oxide; and(c) an aluminum containing component which may be (i) aluminum or (ii) a mixture of from 50 to less than 100 weight percent of aluminum and from more than zero to 50 weight percent of a metal which can be magnesium, zirconium, bismuth, beryllium, boron, tantalum, copper, silver, niobium, or mixtures thereof; and(4) means for igniting the pyrotechnic material. This device is useful as an explosive, particularly as an underwater explosive.
