Yeah my heart jumped into my throat when I sarted intercepting strong high frequency active pinging on multiple bearings all at the same time consistent with Soviet Type 75 sonobuoys.
I had a sound speed profile up from the last expendable bathythermograph dataset but it showed no boundary, just a positive gradient from the surface to the sea floor, so the passive sonar environment wasn't going to help me this time

.
I think the best tactic would have been to anticipate the search pattern of the Be-12 and make sure we never get within 10nm of each other :hmm: ... risky business hanging around at P.D. with the ESM mast raised though.
Boy I am enjoying getting back into SCU/SCX Sub Command ! Upholder is a nice sub to drive.
