The NMCC includes several war rooms, uses more than 300 operational personnel, and houses the United States side of the 1963 Moscow–Washington hotline which links the Pentagon and the Kremlin. Data into the NMCC includes the warning "on the size, origin, and targeting of an attack" (e.g., from the NORAD/NORTHCOM Command Center). The NMCC's Crisis Management Automated Data Processing Systems are under the control of the J-3 Command Systems Operations Division.
