Speed and Sea State
Just wanted to chime in here with this small note - I have no idea how the game treats it but speed is an absolute huge factor in Sonar. Why? The faster you move through the water the more your own noise adds (logarithmically) to your side of the noise equation and eventually you are moving to fast to hear the return of the echo or to passively hear the contact. So if you are going ANYTHING above 15 knots you are flying blind - particularly with WWII style active. Today’[s stuff a little different but in this time frame - you would only be seeing your own return from the sea noise if anything at all. The game has the skimmers screaming around at high speed going active and changing course - total . Passively this effect (becoming self noise limited) happens sooner. In high seas your sensors (Active and Passive) are useless for the most part. Le (ownship's component) (Powersum) + La (Ambient Limited) = LE (Total background noise). \ASW is a fairly prolong and time consuming process.
