Department Description:

The W80-4 System Integration Departments are part of the Sandia/California Weapon Systems Engineering Center. The Weapon Systems Engineering Center is responsible for assuring the safety, reliability and security of U.S. nuclear weapons enabling the defense of our nation through our nuclear strategic deterrent. The W80-4 System Integration Departments are comprised of a group of dedicated and motivated engineers with advanced technical degrees, primarily in mechanical and electrical engineering. A major effort for this organization is the engineering design and development in support of a Life Extension Program for a nuclear warhead (W80-4). The W80-4 warhead will be deployed on the future U.S. Air Force Long Range Standoff (LRSO) cruise missile that will replace the existing Air Launched Cruise Missile (ALCM)/W80 Warhead weapon system in our nation's nuclear deterrent stockpile. This is a long term program that will require close collaboration with many different departments within Sandia as well as with organizations outside of Sandia such as LLNL, NNSA, Production Facilities, and the Department of Defense (DoD).
