    • Weapon Systems Engineering (W)

      The Weapons System Engineering (W) Division provides the program management and system engineering necessary to sustain the safety, reliability, and security of the legacy nuclear stockpile. The division generates key certification data for annual assessments on the health of certain warheads. This role demands ongoing surveillance of the active stockpile and evaluation of the potential impact of any issues.

    • Weapons Engineering Facilities Operations (WFO)

      The Weapons Facilities and Operations (WFO) Division operates, maintains, and constructs infrastructure in direct support of mission-focused research and development efforts. The division ensures readiness in mission execution, operations, and maintenance at over 500 Laboratory facilities across 23 square miles, including nuclear, accelerator, and high explosives portfolios.
