Modern subsims hunt and attack submerged never surface, stay submerged and remain undetected. Sonar is your friend.

Thats not strictly true, the moreso in the post cold war era.
If you're talking about blue water nuclear submarines then i agree with your assessment.
Another thing is doing littoral warfare with diesel electric subs such as the kilo.
Makes for a very wwii-ish experience.
