The Directed Energy (DE) Systems Symposium focused on systems aspects of DE in a limited-attendance environment. The Systems Symposium consisted of co-located technical sessions organized by four separate conferences, with joint technical and plenary sessions to encourage discussion outside narrow technical limits. The meeting was an outgrowth of the Tampa meetings held in March 2005, which co-located the Directed Energy Modeling and Simulation and the High Energy Laser Lethality Conferences. It was also an outgrowth of the Workshop on the Employment of DE Weapons, held in Newport News in May 2004.
Registrants were allowed to attend any session of the Symposium for just one registration fee. Attendance at all sessions was limited to U.S. citizens with classified visit requests, including need-to-know certifications, on file. Classified sessions were held at the Naval Postgraduate School while unclassified sessions were held at the Hyatt Regency Monterey.
