This bill directs the Secretary of Defense to update the Pentagon's Critical Asset List within 180 days to include assets necessary for developing, deploying, and operating a new missile defense system called "Golden Dome." The bill responds to congressional concerns about advanced missile threats from China, Russia, Iran, and North Korea by establishing a comprehensive air defense architecture that combines space-based detection and interceptor systems with ground-based radars and other sensors. The updated list must include space-based systems, ground-based missile defense facilities in Alaska, Florida, Georgia, and Indiana, and supporting command and control infrastructure. Within 270 days, the Secretary must also report to Congress on the updated asset lists, a strategy for protecting these systems from missile threats, and an assessment of risks including cybersecurity vulnerabilities. The bill does not specify new funding amounts but requires coordination with military commanders to align defensive priorities and resource allocation with the Golden Dome initiative.
