Advanced combat direction system

It upgrades the Naval Tactical Data System (NTDS) for aircraft carriers and large-deck amphibious ships.

ACDS integrates the ship's sensors, weapons, and intelligence sources to allow command and control of battle group tactical operations.

The Block 1 upgrade includes modifiable doctrine, the Joint Tactical Information Distribution System (JTIDS) for joint and allied interoperability, increased range and track capability, multi-source identification, National Geospatial-Intelligence Agency (NGA) based digital maps, and an embedded training capability.

ACDS was replaced with the Ship Self-Defense System (SSDS) Mark 2 as it was fielded across the fleet.

ACDS Block I development, performance, and integration testing: Raytheon; SPAWAR Systems Center, San Diego, California; and the Integrated Combat Systems Test Facility (ICSTF) and Naval Surface Warfare Center Port Hueneme (NSWC/PHD) (Later, Combat Direction System Activity (CDSA)), Dam Neck, Virginia.
