I thought that AvH did use the BOLD device to not only generate the bubble cloud but an acoustic disturbance that "distracted" the DDs momentarily to give a kaleun the small chance to slip away?
I take it the files you refer to in further experimentation are the sensors.dat ,.val, and .sim files, along with the DepthCharge files?
It would be interesting indeed if a workable solution could be found. The escorts' sensors work too well as it is by being able to "hear" and "see" you through all manner of obstructions and interference. This would help to level the playing field a bit without pulling the enemy's teeth.
Food for thought and a wise word of warning. Thanks for your continued input, Kpt. Lehmann!
