Beneath the Surface: Securing U.S. Submarine Assets in the Cyber Domain

Submarines have long been the silent sentinels of the sea, protecting our interests through stealth, endurance and strategic deterrence. But as warfare evolves into the digital realm, so must our defenses. Today, the ocean floor isn’t the subs’ only battleground; the cyber domain is now a critical front line, and our most advanced undersea platforms are increasingly in the crosshairs.

From Periscope to Protocols

Traditionally, submarine defense focused on acoustic stealth, propulsion and sonar evasion. But in an era of network-centric warfare, U.S. submarines now rely on sophisticated digital systems. This includes communications, navigation, weapons control and AI-assisted threat detection.

These advancements have exponentially improved operational capability, but they’ve also introduced new points of vulnerability. As early as 2008, security researchers raised concerns about legacy systems aboard some vessels being exposed to cyber risks due to outdated software and a lack of encryption. While modernization efforts have since ramped up, the threat landscape continues to expand.

Real Threats in a Rising Digital Tide

Modern submarines, including those in the Virginia and Columbia classes, are equipped with integrated systems that leverage satellite uplinks, wireless command interfaces and even cloud-based support platforms. While secure, these systems aren’t impervious.

A U.S. Government Accountability Office (GAO) report cited multiple cyber vulnerabilities in Department of Defense weapons systems, including those used in the Navy. The report pointed to weaknesses in supply chain software, patching protocols and system monitoring. Even simulated red team exercises have repeatedly demonstrated that critical systems can be accessed if not proactively defended.

And while U.S. military technology is rising to meet these challenges, other nations are also advancing.

Peer competitors like China and Russia are investing heavily in cyber and undersea warfare. For example, Russia’s Poseidon unmanned undersea vehicle and China’s growing submarine fleet benefit from advanced cyber-electronic warfare strategies. These nations understand what’s at stake, and they’re designing systems intended to disrupt, disable or intercept our digital naval communications.

Where the Fight Goes Next: Mitigation and Innovation

The U.S. Navy and its partners have begun addressing these evolving threats with cutting-edge cybersecurity initiatives. Key developments include:

  • Embedded Cybersecurity-by-Design: New submarine builds prioritize cyber resilience from the ground up, ensuring secure configurations, authenticated boot processes and real-time anomaly detection.
  • AI-Powered Threat Detection: Emerging AI tools help detect unusual behaviors in mission-critical systems, flagging potential breaches before they become operational threats.
  • Zero Trust Architectures: Increasingly deployed within military IT ecosystems, these models enforce strict verification protocols at every layer of system interaction.

A recent example of this mindset is Task Force Hopper, a Navy effort combining data analytics, AI and cyber defense into unified operational readiness. While not limited to undersea forces, the initiative reflects a larger shift toward agile, cyber-hardened systems across the fleet.
