The current political and economic situations suggest that significant reductions of nuclear forces outside the US will continue. This implies that in times of crisis the rapid deployment of nuclear weapons into a theater may be required. This paper describes a proposed Mobile Integrated C{sup 3} and Security System (MICSS). The MICSS, together with associated personnel, could satisfy the command and control and security requirements of a deployed nuclear operation. Rapid deployment poses unique nuclear weapon surety difficulties that must be overcome for the operation to be effective and survivable. The MICSS must be portable, reliable, limited in size, and easily emplaced to facilitate movement, reduce the possibility of detection, and minimize manpower requirements. The MICSS will be based on existing technology. Sandia has designed prototype mobile command centers for the military. These command centers are based on an approach that stresses modularity, standards, and the use of an open architecture. Radio, telephone, satellite communications, communication security, and global positioning system equipment has been successfully integrated into the command centers. Sandia is also supporting the development of portable security systems for the military. These systems are rapidly deployable and mission flexible and are capable of intrusion detection, area and alarm …
