Nuclear Command, Control, and Communications (NC3) delivers advice to the Secretary of War on policy, direction, Congressional engagement, and Milestone Decision Authority on select NC3 programs to facilitate presidential command and control of nuclear forces. Effective nuclear deterrence demands an assured, resilient, and reliable NC3 system that performs critical functions including situation monitoring, planning, decision making, and force direction and management. The NC3 System must ensure timely and cost-effective fielding, end-to-end capability, and advancement to stay ahead of evolving threats.
