What is the difference between a sensor net and a weapons net in an IADS?

• A. The two nets are identical in function and no distinction exists.
• B. A sensor net coordinates logistics; a weapons net handles airspace management.
• C. A sensor net connects sensors for target data; a weapons net connects fire control and weapon systems for execution of engagements.
• D. A sensor net is used for weather forecasting; a weapons net is used for communication.

Answer: (C)

In an IADS, two separate networks carry out different parts of the mission. The sensor net links radars and other sensors so they can share target data, track objects, and provide a fused picture of the air situation. The weapons net links fire control systems, command and control nodes, and weapon launchers so that once a target is identified, the engagement can be directed and executed. So the key difference is data collection and sharing versus coordinating and delivering the weapons to strike. The other options don’t fit because they misstate the roles: the nets aren’t identical, one isn’t about logistics or airspace management, and they aren’t used for weather forecasting.
