Apparently but ATC had 2 options 40 knts and max (passive/active) Now the AUUV 4 kts option has a depth cycle anomaly, and the 20 kts one rapidly burns out.. Surely washout speed/s are'nt set in stone ? So is 'knobology' really the cause ? :hmm:
Edited after more testing :
However, I have to say, the current 306 stealth deployment at 12 knts giving a tested 11 nm appx. actual range and 1 hour duration is pretty useful.

And a sudden acceleration to 20 kts can freak the target and requires more identification and classification skills from a manual sonar operator.
In addition the 20 knt rapid, pre passive state, deployment will be useful v incoming......so after testing and reflection I like it the LWAMI 306 way after all.
