What is a multi-static non-coherent extended echo ranging (EER) buoy?

The correct answer describes a multi-static non-coherent extended echo ranging buoy as one that operates on one of 31 RF channels and has explosive payloads. This aspect highlights key functionality and operational characteristics of the buoy.

In naval operations, EER buoys are utilized for listening to underwater sounds and detecting incoming threats such as submarines. The operational capability to function across various RF channels is important for effective communication and coordination among multiple assets in a military setting. Additionally, the mention of explosive payloads indicates that these buoys may be deployed not only for data collection but also for offensive or defensive actions, which aligns with the military applications of such equipment.

This answer emphasizes the strategic value of EER buoys in enhancing situational awareness through advanced detection capabilities.
