Here is the information on the towed array deployment from LWAMI's read-me.
688(i) Towed Arrays- Added TB-23 as starboard array. The reason I have kept it
on the starboard, against what is commonly reported, is because in missions
where ownship starts with TA deployed, it is always the starboard array, and I
figured in most situations I would want that one deployed. The port TB-16
washes out at ~20kts and the TB-23 washes out at around ~16kts (you folks
can tell me if that feels right once you play around with it...
or if I'm just completely off...). I have set the sensitivity of the TB-23
to be pretty much in the middle of the TB-16 and the TB-29. I was even able to
change the names in game, so have fun captains!
