Why is the requirement for submarines to detectable noises crucial for active sonar?

The requirement for submarines to produce detectable noises is crucial for active sonar because it enhances the accuracy of detection. Active sonar systems work by sending out sound waves and listening for echoes that bounce back from objects in the water, including submarines. If submarines produce detectable noises, it can contribute to a clearer and more precise understanding of their location and movement.

The use of detectable noises can aid sonar operators in distinguishing between different underwater sounds, thereby increasing the reliability and accuracy of target identification. This detection capability is vital for engaging in effective maritime operations and maintaining situational awareness in naval engagements. The ability to accurately detect and track submarines or other underwater objects can significantly influence operational planning and decision-making processes.

While the stealth capabilities of submarines might seem relevant, they primarily pertain to avoiding detection rather than enhancing sonar accuracy. The identification of friendly vessels and changing operational depth are also important, but they are not directly related to the role of audible noise in the effectiveness of active sonar systems.
