Should Coast Guard cutters carry sonar?

Should modern Coast Guard cutters carry sonar?

Some basic acoustic capability is plausible, but full anti-submarine suites across the Coast Guard would be difficult to justify.

The answer expects some acoustic capability or provision for it on major cutters, especially in wartime roles. Legend-class ships are described as fitted for additional sensors even if a complete towed-array suite is not routinely installed. It rejects the idea that every Coast Guard ship needs a costly full-spectrum ASW suite. Fixed hydrophone networks and specialist ships are more efficient for persistent surveillance, while selected cutters can retain wartime growth capacity.
