As the Navy’s Information Dominance systems command and technical lead for C4ISR, SPAWAR provides the hardware and software to connect our warfighters at sea, on land and in the air. They support the full life cycle of product and service delivery from the initial research and development, to acquisition and deployment, to operations and logistics support. SPAWAR is one of three major Department of Navy acquisition commands. While other systems commands focus on tangible platforms, information is SPAWAR’s platform. Their products and services transform ships, aircraft and vehicles from individual platforms into integrated battle forces, delivering and enhancing information dominance and awareness among Navy, Marine, joint forces, federal agencies & international allies.
