About the Team:

The Modeling & Simulation team builds the simulation capabilities used to design integrate test and validate advanced aerospace and defense systems. We develop physics-based models simulation environments and analysis tools that help engineering teams evaluate system behavior improve designs and reduce risk before hardware design integration test and fielding.
