What is a "drogue" in mine countermeasures?

In the context of mine countermeasures, a "drogue" refers to a device that is deployed to enhance the maneuverability of towed sonar systems. The primary function of a drogue is to maintain the correct depth and stability of the system while it is being towed through the water. This allows for more effective detection and classification of underwater mines. By using a drogue, operators can ensure that the sonar system remains at the optimal depth and position to gather the most accurate data while minimizing interference from surface conditions or vessel movements.

The other choices do not accurately describe a drogue. While explosives and underwater traps are related to mine operations, they serve different roles within mine warfare. Similarly, protective gear for divers is essential for safety but does not pertain to the function of a drogue in improving sonar functionality during mine countermeasure operations.
