How is the AN/AQS-24 Sonar best described?

• A. A fixed-wing search radar
• B. An active-controlled helicopter-towed mine hunting sonar
• C. A handheld metal detector
• D. A trailing magnetic anomaly detector

Answer: (B)

The AN/AQS-24 is an active sonar system deployed from a helicopter and towed behind it for mine hunting. It emits acoustic pulses and analyzes the returned echoes to image and identify mines on or buried in the seabed. The “active” part means it sends sound and listens for the reflections, while being “helicopter-towed” provides a stable, extended search reach away from the aircraft and lets crew control depth, tow geometry, and search patterns to suit sea conditions. This focused combination distinguishes it from other sensors like surface radar, handheld metal detectors, or magnetic anomaly detectors, which operate in different domains or with different detection principles.
