Please correct me if I'm wrong, as I'm new to this, 
But I thought we were able to use passive sonar for ship identification in Narrow Band signatures also. Isn't that useful enough, so that you won't have to raise the periscope for positive ID at all? |
You certainly can detect, classify, and localize a target with enough accuracy to attack using only passive sonar. But, if you have the ability to get a range and course with the periscope nearly instantaneously, why not use it? Mistakes are costly; better to use the best tools you have when you can.
