View Full Version : V&W keeps acquiring me... why?

Ok I am currently stuck in a situation where I am not only dead on in front of the convoy, I am 2k yds in front of the escort as well. I am at periscope depth in silent running and dead stop. Yet somehow this critter keeps finding me and blasting me with pings, and I am forced to waste a shot killing him. Subsequent events lead to me killing the liner I am there for, and the other escorts getting me. But I am puzzled how they are finding me while I am busy being a black hole in the water. Oh its night too, no chance of seeing my outline. Ideas?

ASDIC. Once you're no longer on the surface, it can pick up your signature.

Perhaps I didnt make myself clear. Something is making it start pinging. destroyers didnt just go around pinging everything 24/7. I am trying to find out why it gets suspicious enough to begin pinging.

Oh no...Destroyers did start active random pinging around the periphery of the convoys...That was Standard Operating Procedures towards the later part of the war. As the war progress, more escorts get ASDIC and get better at using it.

You haven't told us the year you are in. Another give-away may be that they are using centrimetic wave radar witch WILL pick up your periscope alone!

Do you ever wonder why, later in the war why U-boat captains started taking random torpedo spreads from great distances away from convoys, then quickly diving away...They knew better.

If you don't have your scope up, does the escort cut engines 1x and/or 2x then start pinging you like there's no tommorrow.

It happened to me but I was running at 1 knot. Had to do an emergency dive and then found out later that they also must have had radar. It seemed that I'd just run into Commander Walker or a mate of his. I eventually retired from this convoy as I could not get near it.

it is late 42 and I only had my scope up once at about 2700 yds which was when I figured out my situation and went silent. I raised again once he pinged me to see where he was and he was about 800 yds off my port bow when he started. I guess its just random pinging and my bad luck to be there.

I am also on the defensive right now, leaving a convoy, 1 degree right rudder silent running, they know I should be here, but they dont know exactly, cause I turned around and ran in time. I usually dont do this but being attacked by a V&W and for some freaking reason the first torp did not explode, after that I used the rear, but now two more V&W are coming up, and to not have the stern tube loaded as a reserve scorpion sting I dont want to be near a DD, so it is time to search for the exit...............

You omitted information about weather and light conditions. Flat seas and moonlight could get you spotted. What about anti-sonar coatings? Do you have them?

Dead on is non-optimal. Come in from an angle so that as you start to get close, the lead escort has passed. He'll probably run circular patterns but stay slow. Pop your scope - make a quick check of your target and then immediately down scope. Also, don't pop your scope until the SO says the lead escort is moving away.

another thing I do with popping my scope up and down, is only raise it as far as the wave crest. With this you get a decent (blurred) view but the scope is more or less hidden half the time.

I did this next to an escort (~100m) and a whole row of merchants and had no reaction. Maybe I was lucky that time.? http://forums.ubi.com/groupee_common/emoticons/icon_cool.gif

The optimal approach is about 1:30 and 10:30 on the convoy's directional clock. That will leave you enough room to not get detected by the leader, but will also grant you enough time to get past the flankleader (or just the flankguard). I try to get this position with better escorted convoys.

I'll second this - in other words, around 45 degrees. I varies depending upon the position of the escorts.

Also, the heavier the wave action, the harder you are to detect. Unfortunately, this also makes it harder to hit your targets. However, you can get in close enought to offset that.

i found to keep the dd escort off me in front of a convoy i go to100+mts and silent n still, then once the convoy is at a 90degree spread using the hydrophones i start moving towards the surface without power or slow and once the convoy is 120-140 spread using the hydrophones i've found i can just go to periscope depth at standard speed because the convoy noise is masking me and when the scope surfaces im smack in the middle 1/3 of the convoy line, then the turkey shoot starts using 00 gyro angle since all the shots at 1000mtrs or less, just remember to use mag pistol keel shots on the greater than 20deg shots and aim 1 ship length ahead using steamfish..minimum on the higher angle shots since the fish has to swim further on them. i've noticed that once i shoot off all my loaded fish, i can put my boat right alongside or directly behind a ship and even at high mast the scope isnt spotted...or maybe i've just been lucky.

i'm in a VIIC with only the engine and single flakwilli gun.

That is exactly how I do it, 14m depth instead of saying periscope depths which gives you 12 - 13 meters. 14m is pretty good to scrape the bottom of the DD with if you want to ram him, I think 14m is a good depth to be at.

Yep, I don't mess around either...I set my depth for 14 meters now also.

Interesting... I also use 14 meters. I find it to be perfect for the scope in calm to light wind, you have about 1 meter to give which cuts down on visibility of the scope. And in convoys it is of course safer as you have a greater cahnce of not getting sailed down by some lucky merchant.

i can safely say this is not the cause of your problem. It seems to be some sort of bug or error in the game. I posted about this about half a year ago.

My situation at the time was -

1941, night - sitting close to english mainland, DD patrols only activity.

I am aware a DD will pass close to my position from external camera and loading a previous save after being made out. Thus i sit still and silent at depth while the DD's patrol brings it closer from at least 15km distance.

Sitting completely still, silent running at 50 m depth, i am made out by the DD passing 500 metres away.

Prior to this my 'stealth meter' would be start moving erratically from shades of green to shades of red the closer the DD got.

The moment i am spotted there is an immediate ping sent to my location, followed by quick successive pings and the DD changing course toward me. Prior to this the DD kept normal patrol course and speed.

Which leads me to suspect this is related. Simply said, the ASDIC and listening equipment on the DDs is overdone and can see far too easily. 500 metres is fairly close, but in these conditions there should be no way the DD could make my ship out. The fact that moving within 500 metres of a DD is an automatic spot, or at least in certain circumstances, is very annoying and quite a hindrance to gameplay.

Moreover, your sub seems to give off a noise signature even at standstill on silent running, and the game does not seem to simulate hydrophone rotation and rotation of ASDIC equipment properly.
