both I guess. I'm primarily concerned with surface ships right now though.

Do destroyers in GWX mod have any kind of towed array hydrophones?

Not in v1.03

We tried lassooing a few dolphins during the beta stage but Greenpeace got wind of it and threatened to picket TS and The Lair.
Later on we tried it with a few of the crew but they forgot to mention they couldn't swim so we decided to wait till the mermaids got used to us and became a little friendlier.
Who knows....perhaps in the next version

I didn't mean present towed array sonars but I am not sure whether or not some towed hydrophones were used or even researched during WWII...

[TarJak]

@Gorshkov, No towed hydrophones in GWX or SH3. I believe there were some late war experimentation as a means of combatting the presense of a thermocline, however they were never in widespread use during WWII at least not in the Atlantic where thermoclines usually developed well below the depths that contemporary submarine technology could have reached.

Thanks! I simply thought it could be a good explanation of incredible DD searching efficiency.

Where can I get on the Internet precise U-boot numbers by type in Kriegsmarine's active service during 1939-1945 period in yearly perspective?

Well, when we are discussing about GWX AI, I would like to share a strange episode that I met in the game.

I was raiding the port of Cape Town, and had scored a beautiful hit on a large tanker. I was sneaking away, when one of those bloody armed trawlers found me. Depth under keel was 15 m, and my sonarman told me that three more trawlers were closing. That's it, I thought, it was a nice career.

But. The four trawlers catched me, but instead of depth-charging my poor U-131, they started circeling the boat. They ran around me as dancing around in an ring, newer coming closer than 200 m. This went on about half an hour, when I decided to slowly sneak away. No success, the followed, continuing with their strange manner. There seemed not to be any way out of the situation, until I decided to try to fool them.

Since they never came closer than 200 m, I decided to sneak as close the shore as possible. What would they do if there was only 100 m of water between me and the shore?

An educated guess, anyone?

Yes, all of them ran aground. And then I finished them one by one, with eels.

Does somebody know why the trawlers behaved so strangely? Has anyone had a similar experience?

I'm using GWX 1.3 and the newest Commander.

oh yes, seen stuff like that, it's either they don't have any dcs or don't drop them for fear of blowing themselves up as well, which happens sometimes. I've a picture of a Flower Corvette dropping charges on my boat in shallow water, missing and sinking itself.

If they'd run aground, why waste precious eels on them? you could have made some distance at high submerged speed, gone silent, made a course change and be off to hunt bigger game....

I'd love to see the picture of that Flower.

Part of the problem is that the enamy ASW sensors (and player sensors for that matter) see right through things like LAND MASSES that should mask the sensor but do not.

Sorry mate. Some behaviors from stock SH3 we just cannot fix. The actual AI in SH3 is hard-coded. We can change sensor parameters and sensitivities all day long... However, they will unfortunately remain immune to things/objects that should block/mask their ability to function.

Also, another game bug that we cannot fix:
If you save your game within 35 Km of scripted traffic, it can/will LOSE its scripted waypoints and continue in a straight line, regardless of what lay ahead.

Recommend not saving your game until you are about 50 Km away from port/harbor areas.

Nice pictures, Cranky!

I've had an encounter in the North Sea in which I had to make the decision to attack an escorted freighter in 83 meter water, or lay low and continue on to my patrol grid. I chose the latter.

In my last career (GWX2), I put an eel into a 5500-ton merchie in 15mps winds. Almost immediately, my soundman told me that a warship was closing at long range and high speed. I took the U-52 down to 160 meters, went silent, and turned north.

By the time the fellow got to my last known location and launched a dc attack, I was at a comfortable distance. He made two other dc attacks ... haven't got the foggiest notion what he was attacking ... and by this time, I had turned to the NE, still at silent running. I soon understood that the DD was hanging around my last position, listening, then making high speed runs. Eventually, I increased speed and continued to the NE.

About an hour later, I heard the merchie go down!

Ducimus, I want you to know that what you said in the OP is spot on, and I've made good use of it, in my "careers". It really helps to make sense of what is happening, at any given moment in combat.

And I never go above 100 rpms, when trying to be quiet!

These kind of experiences make SH3+GWX such a great game. You will remember these adventures for a long time.

Exactly! The developers of GWX and SH3 both wanted to create an immersive experience with a game that was only marginally so (in the stock form), and they succeeded marvelously. Ubisoft ought to donate to them, given the number of units they've sold just for the mods ...
