  • Patent number: 6945175
    Abstract: The present invention comprises a kinetic energy penetrator warhead that may engage both surface and buried soft and hardened targets. The warhead contains a high-temperature incendiary (HTI) fill capable of destroying chemical and biological agents in such a manner to minimize dispersal of these agents. Bomblets are incorporated into the portion of the warhead that penetrates to the target and are ejected, with the HTI fill, from the warhead in order to provide holes in chemical or biological agent tanks to allow the fill to react with said agents. Finally, a guidance system is provided to direct the warhead to the target.
