Weapon Verification and Validation

Validating Design. Verifying Performance.

The Weapon Verification and Validation Division (V-DO) verifies that weapon designs meet requirements and validates that the designs function as intended, ensuring successful completion of investigations, qualification tests, and evaluations. V Division accomplishes the verification and validation of weapons designs through assembly, non-destructive evaluation, test design and planning, and test execution.  

  • Experimental Device Engineering and Assembly

    Experimental Device Engineering and Assembly (V-5) is LANL's premier engineering group specializing in assembling experimental weapon test devices. Its team of engineers, technicians, and specialists safely delivers high-quality assemblies that support Design Agency research in weapon physics and system engineering, directly contributing to the Nation’s Stockpile Stewardship program.

  • Nondestructive Testing and Evaluation

    Nondestructive Testing and Evaluation (V-6) specializes in advanced state-of-the-art inspection and non-destructive testing technologies in support of the nuclear weapons stockpile. The group applies expertise in X-ray and neutron radiography, computed tomography, ultrasonics, spectroscopy, eddy current testing, and other nondestructive testing techniques.

  • Test Engineering

    Test Engineering (V-14) provides hands-on test engineering supporting weapons stockpile R&D, production, nonproliferation, and other national security programs. The group specializes in mechanical, structural, thermal, vibration, shock, blast, instrumentation, and data analysis—from material samples to full weapon assemblies.

  • Weapons Test Execution

    Weapons Test Execution (V-21) plans and oversees the execution of weapon testing. V-21 supports experimental evaluation across many domains including mechanical, thermal, hydrodynamic, and sub-critical testing. The group leverages capabilities across the complex, integrating experimental expertise to field large-scale joint tests with weapon development partners, including Sandia National Laboratories, Lockheed Martin, and others.
