  • Patent number: 5511482
    Abstract: A munition which remains uninitiated after deployment undergoes a process of self-neutralization. This process is accomplished through the use of environmentally degradable materials in the construction of the ordnance items. The degradable components comprising the device fail in a predetermined manner and within a known time frame. The resultant neutralization may be manifested in a myriad of ways. The type of degradable material, its position within the munition, its mass, and many other factors, will all determine the ultimate characteristics of the device.The neutralization may be realized through detonation, burning and, disassociation of interactive components which will cause deactivation, reduced lethality or intensity of the device, dispersion of the main charge, or the dispersion of one or more of the initiation charges comprising the munition.
