Been trying to go the opposite way Ducimus went in this thread;

To try and lower the psychic destroyer effect where they hear you from 2 miles away when you have the motors stopped. My thinking was to increase the active range and decrease the passive range, but near as I can tell there's no data in any individual IJN destroyer saying which sonar that particular class uses, or when?
Found the type 3 (1, 3, and 5) and type 93 (1 and 2) A and P, but I notice there's also a type 3 M1P and M2P, are those for merchant ships?
I'm setting up some test single missions in 42 and 44 to trial and error my way through what uses what, but if someone else has already done a list it would save me a lot of tedious testing.
