Lawrence Livermore National Laboratory

LLNL is a U.S. federal research lab founded in 1952, focused on nuclear deterrence, stockpile stewardship, counterterrorism, and national security science.

Lawrence Livermore National Laboratory (LLNL) is a federally funded research and development center established in 1952 and located in Livermore, California. For more than 70 years, it has operated at the intersection of advanced science and U.S. national security, with a defining responsibility for ensuring the safety, security, and effectiveness of the nation's nuclear deterrent through its nuclear stockpile stewardship program.

LLNL's technical work spans a broad range of disciplines organized around high-consequence national security missions. Its primary areas of focus include:

Nuclear deterrence and stockpile stewardship - maintaining the safety and effectiveness of the U.S. nuclear arsenal without underground testing
Counterterrorism and nonproliferation - developing tools and capabilities to detect and prevent the spread of weapons of mass destruction
Defense and intelligence - applying science and engineering in support of U.S. defense priorities
Energy and environmental security - addressing challenges in energy resilience and environmental risk
Fusion research - home to the National Ignition Facility (NIF), which achieved fusion ignition

Work at LLNL is conducted by multidisciplinary teams drawing on expertise across science, engineering, and technology. The laboratory's mission is explicitly oriented toward both national and global stability, with research programs designed to address security challenges that extend beyond U.S. borders.
