As I said, sonar (or the receiving end of it).

More or less. 1918 was the very early days of the technolgy, it was all
passive

The only time the ship I was on used active sonar was in foreign ports, to keep divers away.

What ship was that?

USS Truxtun, CGN-35.

Use of active sonar in peacetime is deprecated because
of the adverse effect on marine life.

Use of active sonar in wartime is deprecated because it announces your position to enemy submarines. For a substantial part of our cruise we were in Condition 3 anyway (wartime crusing), so if we had had such a rule back then, it probably would have been suspended.
