What is the purpose of the Data Link system?

• A. A two-way UHF communications link connecting the airborne data link system with a controlling shipboard, airborne, or land-based combat direction system
• B. A satellite-based navigation feed to ground control
• C. A passive listening radio for surveillance
• D. A diagnostic loop for avionics maintenance

Answer: (A)

Data Link provides a two-way digital bridge that ties the aircraft into the broader combat direction network. Its purpose is to share real-time tactical data with a controlling shipboard, airborne, or land-based command and control system, so everyone has a common picture of the battlespace and can coordinate tasks quickly. This enables updating tracks, targets, and mission instructions between the Growler and the CDS, improving situational awareness and defeat of threats through synchronized actions over the data link.

Other options aren’t the function of this system: a satellite-based navigation feed to ground control is about navigation data, not airborne data sharing; a passive listening radio is used for intelligence gathering rather than providing the commanded, real-time data link; and a diagnostic loop is for maintenance and system health checks rather than battlefield data exchange.
