National Security Starts with Science

Since its founding during the Manhattan Project, Oak Ridge National Laboratory has advanced the science and technology that protect the United States. To address modern and emerging threats to U.S. national security, ORNL translates scientific discoveries into technology solutions.

We bring together world-leading capabilities from across ORNL ­–nuclear, computing, AI, manufacturing, and more to move rapidly from scientific discovery to deployable solutions.

National security cuts across all of ORNL’s strategic priorities:

Translating science from Atoms to Applications leads to breakthrough solutions in defense manufacturing, critical minerals, and biotechnologies.

The Future of Computing includes secure HPC systems, dependable AI tools, and quantum solutions for national security priorities like alternative positioning, navigation, and timing.

Next-generation Nuclear Solutions must consider safeguards, security, and other nonproliferation principles to ensure U.S. nuclear leadership. 

Delivering Secure, Resilient Systems for Abundant Energy will require geospatial-derived insights on energy system interdependency at a national scale – and cyber-physical security assessments of grid components at the chip level. 

The Challenge We Face

An Evolving Threat Landscape

We face these challenges head on, capitalizing on ORNL’s unique scientific assets to deliver real-world solutions that protect the people, infrastructure, and economy of the United States. 

    National security today demands integrated, science driven solutions.

    What We Do

    Reduce Nuclear Risk

    Advancing uranium science, safeguards, and secure-by-design reactor technologies to reduce global nuclear threats

    Secure Critical Assets

    Combining national-scale infrastructure data with device-level technical expertise to strengthen the resilience and reliability of systems we depend on every day.

    Accelerate Delivery of Global Insights

    Enabling faster, better-informed decisions during crises, disasters, and global conflicts.

    Drive Innovation Throughout the Defense Manufacturing Supply Chain

    Strengthening U.S. manufacturing competitiveness and defense readiness

    Enhance Secure Computing and AI

    Ensuring U.S. leadership in computing while defending against AI-enabled threats

    National security today is inseparable from economic security, energy resilience, technological leadership, and global stability. For more than 80 years, ORNL has answered the nation’s call in moments of profound challenge. Today’s threats are complex and evolving—but our commitment remains constant.
