What does 'Ears of ship' refer to in naval terminology?

In naval terminology, the phrase "Ears of the ship" refers specifically to sound detection systems. These systems are crucial for underwater surveillance and detection, enabling a ship to pick up and analyze various sounds in the water, such as those produced by submarines, other vessels, or underwater objects.

Sound detection systems typically incorporate hydrophones and other acoustic sensors that capture sound waves in the ocean. This capability allows naval forces to monitor their surroundings, assess threats, and gain valuable situational awareness.

While radar systems and communications systems are essential for a ship's operational effectiveness, they serve different functions. Radar usually deals with detecting and tracking surface and airborne objects, while communications systems facilitate information exchange. Torpedo launch detection, on the other hand, refers to a more specific concern regarding threat response but does not encompass the broader role of sound detection systems in maintaining maritime security.
