About Us

The Advanced Simulation and Computing (ASC) program at Sandia provides state-of-the-art computer simulation capabilities as part of NNSA's mission to extend the lifetime of nuclear weapons in the stockpile without underground testing. While these tools enable scientists and engineers to gain a comprehensive understanding of nuclear weapons, they are also revolutionizing the way in which a large number of innovative products are engineered. In fact, the computing, modeling, and simulation tools developed in the ASC program are leveraged by a variety of other national security programs.

ASC program activities are shared by NNSA’s three defense laboratories, Sandia, Los Alamos, and Lawrence Livermore. Sandia’s contributions and expertise are described on these pages. For more information about the program at NNSA headquarters and the other laboratories, see Related Links on this page.
