Which is a common data link management system?

Link 11 is widely recognized as a common data link management system that facilitates the exchange of tactical data among various military platforms. It operates in a half-duplex mode, allowing ships, aircraft, and ground units to share operational information such as situational awareness, tracking, and command-and-control commands. Link 11 is integral to naval operations, as it supports communication between different units and enables a unified picture of the battlefield.

Link 11's importance stems from its robust performance in disseminating real-time data, which is crucial for coordinated military actions. Its architecture supports multiple modes of operation, including point-to-point and broadcast, allowing versatile usage in varying combat scenarios. This system has been an essential part of NATO and allied forces' joint operations, ensuring interoperability among different platforms and forces.

In contrast, other data links like Link 10, Link 12, and Link 13, while having specific uses, do not have the same level of commonality and widespread application as Link 11 in data link management across various military assets.
