Default A seemingly stupid question

Have looked through the various posts, newbie guides and GWX guides, and one questions seems to elude a direct answer for me (or I am totally blinded by bernard)

For the front escorts on convoys, if you are setup ahead of the convoy, is there any specific way to avoid being pinged. I have run silent at 150+ meters, or at a complete stop and silent and still manage to get pinged and end up having to either fight it out or run for it. I had a look at some approach strategies for convoys in GWX on here and on external websites but I seem to always get the same result....pinged by the front escort.

Any recommendations?

Generally speaking the whole "submerge ahead and drift til you're in the middle" thing doesn't work with GWX and especially later in the war. Later war Asdics can go down 300+ meters. As I recall Ducimus said that you need to go at least 200 meters to get underneath an early war asdic.

The best approach is to come in from a frontal angle through an escort gap. You wanna avoid a frontal move since the frontal escort is gonna literally be looking straight ahead. The closer you are to the baffles the better too. You need to maneuver nearly as much as the escorts themselves sometimes if the screen is big.

Think of it as a very different game of Frogger.

So 200+ meters for early war depths and come from an angle that will put me behind the DD screen or as close to its baffles as possible. My main problem is I end up in a shootfest with a couple of DD's (who usually end up taking a trip to the sea floor) while I watch the convoy wander off as more and more DD's come out of nowhere.

Fun fun, am going to have to work on my convoy approach tactics!

Doesn't sound like a stupid question to me, I never found any specific tactic either on the boards.

A is the lead escort. Note my AOB is making me a very small target.

B is the next closest escort. Once A has passed a bit I will switch the focus of my AOB to B, if possible.

C shows where the outside row of the convoy is going to be when they reach my position. As you can see I'm just about in it's path already. Even at 1.5 knots I can easily move out of its path when the moment is right and proceed towards my target inside the convoy.



Oh, and of course - I'm under water. : /

In my experience, you don't have to be deep to penetrate a convoy. It is the correct tactic for evasion but you can be at periscope depth when approching/entering a convoy.

The best way to practice this is to have map updates on, that way your can click on the escorts and 'see' their sensor arcs. Usually, there is a lead escort and a flanking escort, use this method to plot your course between them.

Only do this after a period of observation as both escorts will peel away from their course and conduct sensor sweeps. If you try this you will see that it is very easy to infiltrate a convoy in early war. Things change dramatically in later years but the basics are the same.

Good hunting.

Depth is not absolutely necessary Stay to the side of the escort by a distance of at least 1500 metres. When he's past you sneak in before a flank escort reaches your approximate area. This is not an exact science because on occassion they will detect you
Good luck

I made 4 runs at this one convoy last week and I noticed a nice pattern:

One of the flanking escorts broke away from the convoy for a good 4,000-5,000m and then came back. (okay, I really don't remember how far away it went, but it was a sizable distance)



I noted the time. It was 45 minutes past the hour.

Then the next time I attack this same convoy the same escort did it again. I looked at the game time and it was again 45 minutes past the hour.

Same thing happened the next time I attacked this same convoy. Again about 45 minutes past the hour.


I didn't end up using any of these gaps because it was very early in the war and I really didn't need any help getting in undetected. But it's certainly something I'm going to look for as the escorts improve down the road.

No idea if this is something added to GWX or if it's stock behavior or what, but it sure was neat.

I had some luck infiltrating a July 1940 GWX1.03 convoy last night, on the surface, in the dark. Call me Otto . I was ahead of it, off to one side. It had three escorts, one either side slightly leading the convoy and one behind. I stayed at 2 kts and let the nearest front escort get fairly close, then went to ahead full (faster than the Black Swan was going) and pulled away from him and in towards the path of the convoy.

As it was dark I got away with it. A minute later I was just in front of lanes 1 and 2 of the convoy facing at right angles to their path, and the front escorts were drawing away. Sat there (even though I was going red on the detection display a lot!) and waited until I had two lovely big whalers in front and a large merch directly behind. I only had 5 eels left so went for two each for the whalers, stern tube for the merch, all on impact at around 4m depth.

At this point my Otto routine (or nerve) failed me and I hit C. Went to 150 metres then silent running at 2 kts, course roughly opposite that of the convoy but avoiding the rear escort. Got 2 lots of distant depth charges, then nothing! And then the payout - all three ships sank in about three minutes. Over 35,000 tons and not a scratch on me. Nice!

Not quite Otto as he would never have sat in one place or crash dived unless absolutley necessary but nearly.

As Dan and Jim said, go in at Pd at some 45´ ish angle and silent running. Keep your conning tower below the waves and use your scope only for short periods.
Later war, use your standoff range to keep out of the escort screen, if possible. Fire your torpedoes at close to maximum range, scope down, dive and break away.

@ Umfuld:

Maybe a stupid question, but what are al this gray lines between A and B?
I never seen them in game so did you draw all those?


btw thanks for the picture.

They are Hydrophone contacts. There are 2 reasons whyyou may not have these, First - you have no Hydrophone Operator at the station, Second - You have No Map Updates on.

There are a couple of ruler lines drawn on there as well at the left hand side. Done with the ruler tool in the menu at top right on map screen.

Or does he mean the grid lines? Everything is grey.:rotfl:
