Thanks Ref for the answer about screw rpms and them getting a fix that way. It's kind of what I thought but at times doesn't seem to hold "too" true in game. I know their sonar and hyrophones pick them up, so that could be why the DDs end up where "you were". That's if you can get away from your fiing point fast enough without the sub being detected. And that will also depend on you firing distance from the intended target.
Lots of good info coming out of this discussion guys. Keep it up guys.... inquiring minds "need" to know.
