Attendees of the TISP Spring Forum: Role of USNORTHCOM in Critical Infrastructure Protection and Disaster Response learned of the U.S. Department of Defense’s (DOD) efforts to cooperate with federal, state and local agencies and private-sector companies to achieve its mission. The forum, held March 5-6, 2009, at Peterson Air Force Base, Colo., included presentations from North American Aerospace Defense Command (NORAD) and U.S. Northern Command (USNORTHCOM) characterizing their roles in critical infrastructure protection and disaster response and a tour of the Cheyenne Mountain underground facilities. The presentations and tour illustrated the extraordinary capabilities of resilient infrastructure and self-sustaining operations, as attendees witnessed the command’s continual testing of capabilities through daily exercises and contingency planning.
