ok so im cruising towards my next patrol marker when all of a sudden i run into two warships. at the time im heading full flank and i switch it to silent running, i go all the way down to 165 feet, which is as far as it will let me go. and i start moving very slow. these ships still hear me (im guessing with their sonar) they're pinging and combing the area and wont leave the area, they still hit me with their depth charges. im tryin to get the heck outta there as sneaky as i can but they're still on me, i eventually get sunk. im beginning to wonder if silent running really works? how do i get it to where they cant detect me at all and run off?

You can go deeper than 165. Click on the square looking button right under the depth meter and it will change it so you can adjust deeper depths up to 450 ft...

With mods and stock I am not sure, but check which key let's you dive. Should be the D key, just be careful to stop your dive because it won't stop on it's own. You can dive as deep as you dare.......

Find a thermal layer. Keep a narrow profile. If they're pinging you can speed up. Lot's of info on escaping dd's so just do a search and you'll get plenty of info.

Be careful going deep in the stock version. A Gar class (from my experiences) can't go deeper than about 350'. I've been down to 375 with a Gato class and no problems. Like Wolfe said, keep a narrow profile (i.e., blade your boat so that it's thin, facing the enemy). Go as deep as you can below the thermal layer. I always try to keep at least a 40 angle or less when approaching a convoy. Calm waters are not your friend, sonar travels better through it. You not only have to choose which convoys to attack but, what conditions are best suited for your ambush. I'm on my second career and rarely get depth charged. When I do get attacked, I'm usually at least 1000yds away from their efforts. A thermocline (thermal layer) bends sound and makes it harder for the enemy to zero in. They may be pinging you but, they're not getting an accurate return on your position. http://forums.ubi.com/groupee_common/emoticons/icon_wink.gif

Oh btw, "Crash dive command is the (C key)
Learn the knuckle turn. It's on the command bar.

In my experience...silent running "works" only with "first speed" or less (you can do that manually if u like) if they didn't sniff you first. Try stay at 2 km away and try to be in 90 degrees angle.If you are far the head escort doesn't see you.Sometimes there are escort in flanks so watch out who's coming next...I wait , in 90 degrees angle, at 2km away, silently and wait for the head escort to pass and shoot only at the big ships and leave, if there is a flank escort ship on my side coming.

Silent running essentially stops all unnecessary noise making work (torp loading.. etc) on the sub.
It does not reduce the noise that you prop and electric engines make, although it should reduce your speed to 1/3 ahead/astern, which is about 3 knots.
To reduce your noise further, manually set a speed of 1 knot. Or even better - shut down engines.

Escorts can pick you up in 2 ways...
1) Passive listening - This is their main detection method, and if you're going at 1/3 speed they will pick you up if close enough.
Counter - Jump into your passive sonar and track the escorts.. you'll hear them cut their engines for a few seconds - this is the time they're trying to detect you. When they cut engines, you also cut your engines.

2) Active pinging - If you can hear the pinging it means the active sonar beam is directed towards you. Whether they pick you up depends on distance, depth and sub-angle to the beam. You'll know when they have you.

Countering active sonar is increasing range, going deeper, or having the escort ahead (0 Degs) or astern (180 degs)

3)AVOIDANCE When you're trapped with the pinging, at some stage the pinging will stop. At this point go to your passive sonar station and find a slow moving escort. The escorts have to go slow to keep track of you, once the attack begins, the escort will speed up to avoid been damaged by his DCs. At the same time the Escort speeds up, you go flank speed at an angle of about 30-40 degrees to the attack.
The DCs will pop and the escort will slow down to listen again.. at this point you cut engines again.. and wait.

silent running does work but not they way you may think, it's not as if when you give the order, a cloaking device is activated.Basically, your sound signature shuts way down...non critical repairs stop, torpedos are not reloaded, crew speaks softly, speed is slow.Ahead 1/3 is the generic order for SR but i've found it too helpful to the escorts, even in stop.Best thing to do is keep it below 50 RPM, you may do this by looking near the wheel in the conning tower, the gauges in the lower right, look closely, the farther below 50 , the better.Typically, I run at half a knot.I do this by clocking on the square below the telegraph, which brings up the "knot-o-meter", then click the space between one and zero.Sure you move slow and may have to speed up if they manage to drop too close to you but usually in the confusion, sub is quiet enough to slip away most of the time.

You can go deeper than 165 as mentioned above.Like the telegraph, click on the square below the depth meter and an alternate meter will come up, showing depth down to 450 feet.In stock, The Gato can make it to 450 but for limited amounts of time, do that only when you must in order to escape.400 feet is safe for Gato though.Balao can go to 450 no problem.I believe there is no way to go below 450 in the stock game.The other subs like the Gar class etc, wouldnt chance going below 275 for long, they are thin skinned boats.

I used it to great success last night while evading 8..yea...8 DDs. I was down to 350 on silent running slipping away towards the convoy they left wide open! At one point all the DDs had their backs to me heading to the furthest ship dropping DCs so I opened it up to flank to get a bigger gap between us. When they turned back around, back down to 1/3. In the end I had put 8 ships in the covoy to the bottom, as well as 1 DD that was listening for me...guess he wasn't listening for my fish too good.
