The NMCC staff provides continuous operation monitoring, reporting, training, maintenance management, and coordination for all communications-electronics activities and systems supporting the NMCC to ensure minimum essential National Military Command System (NMCS) connectivity for the Single Integrated Operational Plan execution, worldwide situation monitoring, and crisis management. It also provides Joint Staff with ADP operations, support and information relating to operational capabilities of the United States in the area of nuclear command and control, primarily missile warning systems of the Integrated Tactical Warning and Attack Assessment (ITW/AA) network.
The more than 300 people in the NMCC have responsibilities that are operational in nature, and thus it is not funded and maintained by the Joint Staff. The Air Force, as the executive agent for NMCC support, provides logistical, budgetary, facility and systems support.
