The Advanced Combat Direction System (ACDS) is a centralized, automated command-and-control system, collecting and correlating combat information. It upgrades the Naval Tactical Data System (NTDS) for aircraft carriers and large-deck amphibious ships. A core component of non-Aegis combat systems, ACDS provides the capability to identify and classify targets, prioritize and conduct engagements, vector interceptor aircraft to targets, and exchange targeting information and engagement orders within the battle group and among different service components in the joint theater of operations. ACDS integrates the ship's sensors, weapons, and intelligence sources to allow command and control of battle group tactical operations.
