Which type of Link 16 message carries track and position updates?

• A. Time synchronization message
• B. Encryption key distribution message
• C. Data message
• D. Network management message

Answer: (C)

Data messages are the vehicle for sharing the actual tactical information between Link 16 nodes. Track and position updates aren’t just metadata; they’re the payload that tells other units where a platform is, how fast it’s moving, and what its current track status is. That’s exactly what needs to be disseminated for situational awareness and coordination, so these updates are carried in data messages.

Other message types exist for different purposes: a time synchronization message keeps all nodes on a common clock, an encryption key distribution message handles security keys, and network management messages control network configuration and status. Since the goal is to convey track and position information, the data message is the correct choice.
