Which of the following is NOT a consideration in the selection of a Link 16 network design?

The selection of a Link 16 network design involves several critical considerations meant to ensure effective operations and interoperability among different platforms. When determining what is not a consideration, it's essential to first understand the relevance of each choice to network design.

Surveillance capacity needs are a central aspect in Link 16 network design because they directly influence how data is gathered, shared, and processed across various systems. A network must be designed to fulfill the operational surveillance requirements of its users effectively. Therefore, it is indeed a key consideration in the design process rather than something that could be excluded.

On the other hand, ease of updates, network security measures, and system compatibility are all equally important to the overall functionality and longevity of the network. Ease of updates ensures that the network can adapt to changing operational needs and incorporate advancements in technology without significant downtimes. Network security measures are vital to protect sensitive data and maintain operational integrity in a joint environment, particularly in combat or contested scenarios. System compatibility guarantees that various types of equipment and platforms can communicate effectively within the Link 16 framework, which is crucial for joint operations.

Thus, the correct interpretation of the question highlights that surveillance capacity needs are indeed a necessary consideration in Link 16 network design, not an exclusion.
