As the name implies, the mission is to collect acoustic information.

A special towed sonar called SURTASS is extended from the stern.

Collect the “sound crests” produced by submarines from various countries lurking in the sea.

The sound pattern is like a human fingerprint, and if analyzed, it will be useful for future operations.

It can be detected even with a slight screw sound in the sea several hundred kilometers away.
