Having trouble with understanding layers

[Stevan_Segal]

So I have played this game off and on for a while but never got super deep into and would mostly just create simple missions in the editor. The thing is with most of the scenarios if I start near then enemy they will immeidately ping me and kill me. I know there is a layer where the temperature changes and I think you stay just below that line but I have never been able to understand how to calculate what depth the layer is so I know what depth to run at. Also what is the max you can run something like the seawolf without being detected. I usaully keep to 5kts but with their ping that doesn't seem to matter.


So what the best way to understand how the layer works so you can remain harder to detect?

Hey Stevan,

I'll pipe in before the experts do.

What range are you starting at from the enemy ship? I usually try and keep 5NM away from active sonar and above the layer to avoid detection. Though I use RA and play pretty conservatively...

Do you know how to launch an XBT buoy to find the layer depth from the SSP station on the Seawolf?

Is the the mission set up to have a layer (In the Mission Editor - Setup ->Environmental Conditions -> SSP -> Convergeance Zone or Surface Duct)?

People will have differing opinions on speed - I'm a pretty conservative player, so I keep to 5 knots close to the enemy, and 3 when being extra sneaky. Of course, it all depends on conditions, tactical situation, his baffles, etc. Seawolf, you could probably go a little faster...depends on a few factors...

It's best not to think of layers as a 'shield' where you're totally 'undetectable' if you're on the right side of it.

Chazly's Tutorials are excellent for explaining how sonar works in DW.

Shadow Zone:

If you're VERY new to all of this, the USNI also has a 'Sonar 101' video too:

Hope this helps. People who know more than I ever will will no doubt pipe in as well!

Press F2, the last window on the upper right corner is the SSP Chart. In there you can see at what depth the layer is.

That's the problem of most of DW scenarios, Sub pop up at knife fight range. And many of the scenarios don't have a layer.

Regarding the shadow zone / detection range. my experience says they layer in DW will protect you from active sonar ping until 8-10nm distance. Passive sonar signature will penetrate layer at about 3-4nm distance.
