Fortunately, I have heard that the Navy have been investigating a passive alternative. You know how someone who is intimately familiar with the sounds of a forest can detect the approach of dangerous animals (including humans) by noticing changes in the sound of animals and insects and stuff? Apparently, they're working on a system that can use marine sounds for the same purpose.

I’d throw money at people for that to get done. Other night I was sitting outside enjoying nature when suddenly it got too quiet. The dogs stopped barking, the bugs went quiet. I jumped in my car real quick. Even I felt that there was something lurking. Didn’t see what it was, but I didn’t leave the car again for a while.
