What describes the data link used for real-time track updates between CRC and SOCs?

• A. Link 11 real-time updates.
• B. A telephone line.
• C. A printed mail system.
• D. A delayed satellite link.

Answer: (A)

Real-time exchange of radar track data between CRC and SOCs requires a digital data link that can rapidly, two-way transmit tracks, identifications, and command information. Link 11 real-time updates provides exactly that mechanism. It’s designed for air defense C2 networks, enabling multiple centers to share track updates in near real time, keeping the air picture synchronized and allowing timely decision-making for interceptions and responses.

The other options don’t fit that need: a telephone line is voice-oriented and unsuitable for automated, rapid track data; printed mail is far too slow for real-time updates; a delayed satellite link introduces latency that prevents timely tracking and command actions.
