Anybody know what determines how deep you can go? Is your crush depth set randomly each patrol, or is it calculated constantly, or does it stay the same throughout the career, etc? Once, the instant I went below the red line on my gauge the rivets started poppin' but others I go way below wartime records without any damage at all.
It would be interesting if Ducimus could code each historical boat to their estimated crush depths

Barb was a thin skin Gato but went below 700, and IIRC a Gato class returned from 900 and have no damage once. Anybody know if build quality was really that varied between boats?'
EDIT: That Porpoise was USS Chopper, a Balao - went below 1000 during a miscommunication accident.

I still seem to remember another story about a Gato however, that had a lot of trouble with her trim tanks while under attack and was pointing almost 90 degrees up before they got her under control. That's the one I thought went over 900...
