How long after DC explosions am I masked?
 

When there are a couple of DC going off nearby, how long can I ´make noise´ after the last explosion? Or do I have to go silent as soon as the last DC explodes?

good question, in real it can take up to ten minuts or more.
I have a bad feeling that in SH it is instant..

Speaking of dc... can anyone actually CONFIRM SH3 simulating noise by depth charges? I´ve never actually figured it out myself, and I don´t really trust SH3 on this point because when I hear depth charges it´s only some seconds and I don´t even know how close they are (unless my boat is shaken, of course)...

AS

You can have short bursts of the engine after the DC explosions. I guess a few seconds should do (not more than a minute though)

There's nfw this is properly modeled in SH3. You have a few seconds and that's it. And you're lucky if you have that much.

I give the engines a burst of speed during the explosions but when they stop I shut 'em down. I don't trust the devs at SH3 either, I'm pretty darn certain this isn't modeled at all. Shame, really.

If the DD's can hear me and come steaming directly towards my position while I'm directly under a convoy, or behind a piece of land, I doubt that depth charges will mask my engine noise either.

From the moment when an escort goes into it's attack run to when the last DC goes off you can use a burst of speed to either change course or depth.

The above is true if only one escort is on to you.

If more than one is tracking you then use short bursts of speed while the DC's are exploding. As Mel said, maybe 3-6 secs tops, this is enough for a course/depth change. Then drop to 1-2kts & pray.:arrgh!:

I can imagine using this technique (going flank) when the attack run starts. He already knows where I am, so I might as well speed up, and make a turn or whatever.

:yep: - Single Escort Only. If you do this with more than 1 then you're only confirming your position to the others.

I usually speed up, as soon as I hear his engines revving up (that's when he's preparing to launch DCs at you).
When I reach my max.intended speed, I make a hook and change depth, and go back to 1kts again, after the last DC exploded.
It takes some time, before your speed is actually back at 1kts, and I use this time to do more evasives...if you only change depth, you make best use of this time (turning decreases speed faster).

If you are lucky enough to have Decoys, drop one when you start Flanks speed to evade. Use Flank speed, dive, turn or whatever, but drop a Decoy. As soon as the DCs stop and you cut back to 1 or 2 kts the Escort will pick up on the Decoy. It's worked for me in stock SHIII, but seeing I don't have Decoys yet in GWX I haven't been able to see the results.

I have decoys loaded, but haven't used them yet, because I have no idea how many I have at my disposal.
I've been to lazy to try, because reloading my career takes so much time. :oops:
And so far, I was able to stay safe without them.

Use them that's what they're there for. ;) I'm not sure how many are available but I've never used all of them on one patrol. If you're detected you don't need to use but one to try and slip away. Head in a direction other than the one you were on. If picked up again use another Decoy and head in another direction. They do help, that I know. They've saved my subs bacon more than once.

Yeah, think you're right.
It's the choice between a decoy & fast escape, or no decoy & hrs of evasives.
I just gotta remember them next time. :D

It's 50/50 with decoys as some of those destroyer's don't fall for your trick but never the less if you got them you should use them. ;)
