The MOSA Industry and Government Summit & Expo is a convening for government and defense-industry stakeholders focused on the Modular Open Systems Approach (MOSA), open architectures, and interoperability in systems design and acquisition. Held at the Gaylord National Resort & Convention Center in Oxon Hill, Maryland, the event combines panels, technical briefings, and an exhibit hall to showcase MOSA-related technologies, practices, and policy developments. It serves as a forum for program managers, engineers, and policymakers to discuss implementation challenges and advance collaboration between industry and government.
