Under the Directed Energy (DE) umbrella, there are two significant areas of interest: high-energy laser and high-power microwave (HPM) weapon systems. At the Naval Surface Warfare Center Dahlgren Division (NSWCDD), the growing demand from the operational community for novel DE weapon systems resulted in a corresponding growth in NSWCDD’s technical capability in this area. During a recent reorganization of the Integrated Engagement Systems Department, leadership looked at the two DE areas historically maintained in a single division and made the strategic decision to split them into respective divisions, recognizing the need for continued growth and development in both areas that have similar technical roots.
