Depth-charge turbulence

[Floater]

Correct me if I'm wrong, and apologies if this has been discussed before, but:

In a recent depth-charge attack, I confirmed what I'd been suspecting for a while: that the DDs' sonar isn't affected by the turbulence created by recent depth-charge explosions. This is very disappointing, since it was a crucial factor in ASW operations, and also crucial for evasive manouvers by the sub.

For those that don't know, the detonation of depth-charges cause so much turbulence that all sonar (ASDIC and hydrophone) operations were impossible for several minutes. Captain Donald MacIntyre - an ace ASW destroyer captain and ASW group leader - says in his memoirs (U-boat Killer) that it took about 15 minutes for them to regain sonar capabilities after an attack.

A common evasive manouver for the U-boat (and for other nations' subs) was to travel at highest speed on a new course, unconcerned about noise, for a few minutes after explosions and then return to silent running some distance away.

In this recent attack, I used this tactic after a nearby depth-charging, and another DD, which was starting an approach from behind, matched my manouvres. I turned starboard, so did he. I turned port, and he did the same. This was a co-ordinated attack - a third DD was stopped and listening.

This aspect was modelled in SH2 - I think it's a 10-minute blindness there - so it's sad to see that it's been omitted from SH3, especially when other, much more complex ASW operations are done so well, such as the Johnny Walker Creeping Attack which I was subjected to.

Your thoughts on this?
