Naval Support Activity

Naval Support Activity (NSA) units are integral components of the United States Navy, providing vital shore-based support to fleet operations and tenant commands. Originating during World War II, NSAs were established to streamline logistics, administration, and operational support for naval installations worldwide. Over the decades, their mission has expanded to include base security, infrastructure management, and quality-of-life services for sailors and their families. Today, Naval Support Activity units continue to enable fleet readiness and mission success by ensuring that naval installations operate efficiently and effectively in support of the Navy’s global objectives.
