The invention, as embodied herein, comprises a new composition that provides different outputs depending upon the level of stimulus supplied to the composition. More specifically, if the composition is subjected to a weak shock, the composition produces fragments that burn upon their surfaces. If the composition is subjected to a strong shock, the bulk of the fragments will initiate, and, depending upon the make-up of the fragments, an explosive, propellant, or pyrotechnic, a different output will result.

1. A composition, comprising:a plurality of shock insensitive, energetic fragments, each fragment a complete energetic formulation comprising at least two different components selected from the group of explosive particles, fuel, oxidizer, and binder; and, a base material to hold the plurality of fragments together wherein a weak shock results in ignition of a surface of the fragments and a strong shock results in initiation of the fragments. 2. The composition of claim 1, further comprising a shock sensitive coating substantially covering the fragments.3. The composition of claim 2, wherein the base material comprises a substantially inert material.4. The composition of claim 3, wherein the base material comprises about less than 10 percent by weight of the composition.5. The composition of claim 4, wherein the base material comprises from about 3 percent by weight to about 5 percent by weight of the composition.6. The composition of claim 5, wherein the base material comprises a binder.7. The composition of claim 6, wherein the fragments comprise an explosive formulation.8. The composition of claim 7, wherein the fragments comprise PBXN-110.9. The composition of claim 8, wherein the shock sensitive coating is selected from PBXN-301 or a PETN powder.10. A warhead, comprising:a plurality of shock insensitive, energetic fragments, each fragment a complete energetic formulation comprising at least two different components selected from the group of explosive particles, fuel, oxidizer, and binder; a base material to hold the plurality of fragments together wherein a weak shock results in ignition of a surface of the fragments and a strong shock results in initiation of the fragments; an explosive booster material, proximate to initiation means, to provide a weak shock; and, a metal case, surrounding the base material.
