What are the two main types of data links used in Navy communications?

The two main types of data links used in Navy communications are indeed Tactical Data Link and Link 16. Tactical Data Links are key to modern military operations, allowing various platforms such as ships, aircraft, and ground forces to share tactical data in real time. Link 16, specifically, is one of the most widely used tactical data links, providing secure communication capabilities and facilitating the exchange of real-time situational awareness data.

Link 16 enhances interoperability by allowing different services and allied forces to communicate using a common data link standard. It supports a variety of data types, including radar tracks, targeting data, and engagement information, which is critical for effective command and control in joint and combined operations.

Other options, while they represent different aspects of communications, do not specifically identify the primary data link types utilized in Navy operations. Voice and Video Links, for instance, do not encompass the tactical data requirements that Link 16 and Tactical Data Links provide. Similarly, Secure and Non-Secure Links refer to the encryption and security aspects of communication rather than specific data link systems, and Link 12 and Link 20 are less prevalent compared to Link 16 in the context of tactical data exchange in Navy operations.
