Well it is 1941 now in my campaign I think my easy days are over. If the enemy pings me im in trouble.

What tactics do you use to get away?
Or to atleast keep those depth charges far enough away from your boat til they give up?

This game just gets better and better. Those warships are really a handful.

So what are your tactics? What do you do after being pinged?

You have decoys... fired out the back of your sub.

These present another sonar contact and confuses the enemy http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Its in the manual my friend

One Approach to escape his Asdic is....

let him close onto you if you don't have decoys... try to steer an angle of 45? from his direction he came from, once he's close enough...very close switch from 1/3 to Flank speed and do an U turn after doing this you can hold speed for 1-2 minutes because you are in his rear....after this switch back to either minimal speed or silent running. While doing these manuevers you have to be as deep as possible, this way his bombs have to fall at least 150m and he also have an harder time to detect you with his asdic....however, i trained this strategy with external cam on, it'll help you with the excersices to that approach.

How about the termal layers, i dont find them present in the game. Did we not discover them until after the war?

Escorts are certainly annoying, I got SHIII only a few days ago but I have found one tactic that works pretty good. That is torping the escorts first http://forums.ubi.com/images/smilies/784.gif. I'm pretty good at head on bow shots with destroyers http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif.

The presence of a thermal layer (and how it potetially affected acoustics) was known at the time, but U-boat captains had no standard way of knowing where the layer boundary was with any useful certainty.
According to stories told by uboat skippers, nobody bothered with finding/exploiting thermal layers.

AFAIK the best they could do was to go as deep and quiet as possible and hope for the best.

Whenever the DD starts to ping you, you have very limited choices for escaping active sonar. The first and most important is your profile to the source of the ping.If you have abroadside to the source,your going to be picked up easily, you need to lower your profile by turning into, or turning a full 180 to the source. This will lower you profile.
Depth, active sonar uses the rebound of the ping to determine location, speed, and depth. Once the ping has resounded off the hull, there is nothing you can do, you must use depth, water temp, and heading to Weaken the ping before the signal even reaches you. Thermal layers were useful not because it destorted the ping results, but how the ping even reached it's target or not.

also if you are struggling hard to get rid of them, save your battery and sit on the bottom for a while ( providing you can get to the bottom ) sit there for a while and rise slightly and begin edging away under silent running at 90 degress left or right of your current heading. If they follow you drop dead again, this is risky however as you can run out of air, but you will run out of air alot slower than battery power, so the choice is yours http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

I sit under a ship if possible. I attacked a tanker and disabled her with two torpedoes in the rear. She is listing slightly and stopped dead in the water. Escorts of course don't take kindly to this. For a brief time I had about 6 escorts nosing around. They pinged me. It didn't matter as they would not drop DC's on me as it would mean attacking the tanker. After awhile there were only two escorts hanging around; one circling the other stopped near the tanker. So, now it's a waiting game. I'm waiting for my torpdoes to reload and I'm waiting to see if the escorts will leave. I've saved the mission because it was getting late and will reload it to see what happens next. Who knows, if that stopped escort stays there long enough, I may have to come to pd depth and let him know the sub is still there.

I've been using a simple tactic that's worked so far...no scratches on my paint.

I do as others have said as far as keeping it to my front or rear quarter, running deep and silent. I'll use my hydrophone to listen for it's motor spooling up for the attack run, as soon as I hear him revving I'll go hard rudder to the side he is approaching on, flank speed, and wait to hear charges in the water. As soon as I hear those, I'll return to slow speed and resume my original course.

I've played this cat and mouse for over an hour on a couple of occasions, but I always get away. http://forums.ubi.com/images/smilies/25.gif

How could you save while submerged ?

Yes thats a very good one actually, good point!

One thing to watch tho is that the ship doesnt decide to sink right on top of you lol http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif

This used to work fairly well for me in SHII. I haven't had an opportunity to try it yet in SHIII. It's been awhile since I've used it so the distances may be off a bit.

Keep in mind I try to leave some cushion depth under the boat just in case of depth charges.

If there's time change course and head straight for the destroyer at ahead standard. At about 2000m or so (depending on speeds) start diving for your operational depth. At 1000m hard to port or starboard at ahead flank. The idea is to be on a course perpendicular to the destroyer fairly close to the time it's right on top of you, but not to give it enough time to change course to match you.

Once you're perpendicular go silent for a while and then make another 90 degree turn and ascend back up to your cushion depth.

Does anyone know just how big the area of disruption that's made by exploding depth charges is? If it's large enough, you might try keeping that between you and the escort, to block his sonar, while you slip away.

At the stage in the war the destroyers may not be working together (or if there is only one). If so the Asdic loses contact with your u-boat when it gets close to you on an attack run. At this point you could turn hard 90deg+ and run full power diving deeper. As the depth charge also makes asdic and their hydrophones ineffective when they explode you will get additional stealthed time from this to make your escape.

However you may get destroyers working in Tandem, one maintaining Asdic contact whilst the other is directed by this ship for the attack run. However once the depth charges are in the water and explode Asdic contact will be lost again and you can employ the above method.

However this method uses excessive amounts of battery power and you can quickly run out. Most often the best tactic is to dive deep, run silent, and as someone else said, if you can bottom the boat so much the better.

The game does model thermal layers and if it is a fine warm day in the Atlantic (summer months) then Asdic contact is quite often very poor and your chances of escape will be considerably better.

What it doesn't model (fairly sure of this) are marine life. Shoals of fish could also give a destroyer a mistaken asdic contact and it could take a skilled operator to sport the difference. However although in real life this 'luck' could happen to a u-boat in this game you won't have this element.

Or.... what I do sometimes even though it gives away your current position BIG TIME but allows you to sneak away a bit, is to fire off a torp or two in his diretion. Sometimes I've been lucky and hit him and the match was already won before it really even started. It can be hard to figure out when to exactly fire them off, but make sure he is not closer than about 700-1000meters in front of you as he closes in. This way your torp(s) have time to arm and get the possible kill on the escort. Even if the torp(s) don't arm and even if the torp(s) miss, the destroyer will usually be forced to change his course dramatically to avoid being hit by your oncoming torp(s). As soon as he makes his change of course you should be diving deeper changing course 15-35 degrees opposite way of his turn and flanking. Now you are furthuring your gap between him and you because he now has to turn around to find you again. Once you get a bit of distance between you and him and get down deep enough -rig for silent running and slip away quietly. Anyways, it might seem like a waste of torp(s), but I would rather lose my torp(s) than my entire sub. Plus, I got a shot or two at him first. I usually only use 1 to 2 torpedoes while doing this if I still have them available. I never like to have all my torp tubes empty. I always like to keep a 'wild card' or two in the tube(s) just for that reason.
