The Vulnerability of Civilian Supply Lines
The U.S. Department of Defense relies on commercial transportation and communication networks to mobilize military power, creating a significant strategic vulnerability as adversaries target these civilian systems. Top U.S. intelligence officials have warned that Chinese cyber operators are compromising hundreds of American transportation, communications, energy and logistics systems to gain persistent access, so that Beijing can disrupt and destroy system at the time of its choosing.
Beijing’s Strategy to Paralyze Logistics
Military operations require the rapid movement of personnel, fuel, and equipment from domestic bases to international theaters. This process relies heavily on privately owned railroads, commercial ports, and civilian telecommunications networks. Because the Department of Defense does not own these systems, military readiness is inherently tied to the cybersecurity posture of commercial partners.
Chinese cyber-actors are positioning themselves to disrupt the systems that the U.S. military requires to project power. If cargo manifests are corrupted or rail dispatch systems are compromised, the ability of the Joint Force to maintain an operational tempo is severely degraded.
Lessons from the Ukrainian Front
The conflict in Ukraine illustrates how modern adversaries target the systems sustaining military power. Russia’s cyberattacks against Ukraine’s transportation, energy, and communications infrastructure reveal that modern wars are fought as much against the systems that sustain military power as the military itself.
This strategy mirrors the “contested logistics” environment that U.S. planners now anticipate. Unlike traditional combat where the focus is on frontline weapons systems, contemporary threats involve “soft” targets—the digital cargo management systems at ports and the flight planning software at airports—that act as the backbone of military mobility. When these systems fail, the time required to deploy combat power increases, providing an adversary with the precise window they need to seize the initiative.
The Regulatory Disconnect
While the Department of Defense has identified specific “strategic” ports and rail corridors essential for national defense, a disconnect remains in cybersecurity oversight. Currently, many smaller transportation operators lack the resources to defend against sophisticated nation-state cyberattacks.
The primary challenge is the lack of harmonized cybersecurity standards across different sectors. Operators often struggle to balance complex, overlapping regulatory requirements with the practical need for hardened infrastructure. Without federal grant programs or integrated public-private partnerships, these under-resourced entities remain the weakest links in the national defense supply chain.
Modernizing for a Contested Future
To mitigate these risks, military and national security experts advocate for a shift in how the U.S. prepares for mobilization. This includes:
- Integrated Cybersecurity Standards: Congress and the executive branch should establish and harmonize cybersecurity standards across transportation sectors to ensure that transportation operators prioritize defense against persistent threats rather than administrative compliance.
- Contested Logistics Exercises: National, regional and local exercises should assume degraded communications, cyberattacks against transportation systems, corrupted logistics data and contested movement inside the United States.
- Federal Investment: Targeted grant programs for smaller ports and rail operators are viewed as essential to ensuring that these entities can meet the cybersecurity baseline required for national security missions.
The ability of the United States to project power will depend not just on the volume of its combat platforms, but on the resilience of the digital networks that move them. Deterrence in the modern era relies on the capability to maneuver through disruption, ensuring that American forces can arrive at the front line intact and on time.
