DSG is unique at Aerospace as it not only directly supports major customers, including Air Force, U.S. Space Command, U.S. Strategic Command, Air Force Materiel Command, and senior leadership at the Pentagon, but also provides a broad range of technical support across the national space enterprise, maintaining vertical responsibilities with customers' portfolios as well as horizontal, matrixed responsibilities across the corporation. The Defense Systems Group (DSG) provides analysis-based decision support to senior leaders on space architectures, policy and strategy, technology development, warfighter capability enablers, systems integration, defense industrial base, and threat reduction to help shape the existing and future space missions across the national security space (NSS) enterprise.
