How Exposed are Key U.S. Airports, Oil refineries, and Nuclear Power Plants to Drone Threats?
AI Analysis
A significant vulnerability exists within US critical national infrastructure (CNI) regarding drone threats, with the vast majority of key sites lacking comprehensive counter-UAS protection. Addressing this gap requires approximately $189.6 million in initial investment for layered RF detection and non-kinetic mitigation systems at 104 critical sites. Legislative action, like the SAFER SKIES Act, and improved inter-agency coordination are crucial for effective mitigation.
Key Takeaways
- 93% of US nuclear sites, 90% of top oil refineries, and 63% of major airports lack comprehensive, layered C-UAS protection.
- Risk profiles vary across infrastructure types, necessitating industry-specific C-UAS strategies.
- Year-1 capital expenditure to secure 104 critical sites is estimated at $189.6 million (RF detection, command & control, non-kinetic mitigation).
- The SAFER SKIES Act and improved coordination between local authorities and site operators are vital for effective response.
- Federal test-bed programs and limited deployments are insufficient to address the current vulnerability gap.
Why It Matters
The lack of C-UAS protection at critical infrastructure sites presents a substantial national security risk, potentially enabling sabotage, disruption, or even catastrophic attacks. This vulnerability highlights the need for immediate investment and policy changes to safeguard essential services and national assets. Failure to address this gap could lead to significant economic and strategic consequences.

How Exposed are Key U.S. Airports, Oil refineries, and Nuclear Power Plants to Drone Threats?
An estimated 93% of 54 nuclear sites, 90% of the top 20 oil refineries, and 63% of the major 30 airports in the United States lack comprehensive, layered C-UAS protection.
Key Findings
- An estimated 93% of the 54 nuclear sites, 90% of the top 20 oil refineries, and 63% of the top 30 airports in the United States lack comprehensive, layered C-UAS protection, signaling a severe airspace vulnerability gap in the American critical national infrastructure (CNI) network.
- Commercial airports, nuclear plants, and oil refineries have varying risk profiles against drone threats, indicating that the success rate of any counter-drone strategy will depend on factoring in industry-specific threats, challenges, and blind spots for effective protection against adversarial actions.
- Targeted large-scale funding rounds in proven technologies and accelerated timelines will be pivotal in securing American airspace against drones. The estimated Year-1 capital cost to secure 104 critical sites in the US with layered RF detection and non-kinetic mitigation stands at $189.6 million.
- Cooperation between local authorities and operators at critical sites through legislative instruments, including the SAFER SKIES Act, will be crucial for mitigating drone risks. Streamlined coordination and a clear delineation of response jurisdiction will ensure threats are neutralized on time without incidents of friendly fire.
Despite escalating warnings from federal agencies and a documented surge in drone incursions across the homeland, the vast majority of US critical national infrastructure (CNI) remains unprotected against unmanned aerial system (UAS) threats. To understand the true extent of this gap, we have evaluated the current state of counter-UAS (C-UAS) deployment across three high-risk categories in this analysis: the top 30 US airports by passenger volume, the top 20 oil refineries by capacity, and the 54 operating commercial nuclear power plants.
The findings reveal a severe vulnerability gap. While federal authorities have initiated test-bed programs and limited deployments, an estimated 93% of the 54 nuclear sites, 90% of the top 20 oil refineries, and 63% of the top 30 airports lack comprehensive, layered C-UAS protection.
The financial barrier to closing this gap is substantial but quantifiable. Modeling the cost of layered RF detection, command and control, and non-kinetic mitigation systems indicates that securing these 104 critical sites would require approximately $189.6 million in Year-1 capital expenditure, with a five-year tota
