TADIXS

The Tactical Data Information Exchange Subsystem (TADIXS) is a military communications system designed to allow the exchange of tactical information between commanders using the Global Command and Control System-Maritime (GCCS-M). Specifically, TADIXS allows for communication between land-based (shore) computer systems and those on U.S. Navy fleet ships deployed around the world.^[1]

TADIXS has entered^[when?] its fourth phase of development and is likely to replace the Officer in Tactical Command Information Exchange System (OTCIXS).^[2] This information exchange improves the overall situational awareness of tactical commanders in the field and strategic commanders at command and control centers.
