Sub Defense?

ok guys...this game is awsome but i seem to have a major problem with evading depth charge attacks. At what speed can you cruise underwater without them picking you up on hydrophones? At what speed do destroyers engage or use their hydrophones. I have been under water with engines off....rigged for silence and they still find me! How is this possible when their asdic nor hydrophones can possibly pick me up at low depth with no sound? If anyone can give an extremely intricate explanation of this please do....your help is highly desired!

Hi and Welcome.

The trick is to keep chaing depth course at 1/3 speeds.

ASDIC can still find you even if youre dead silent.

The AI usually engages you at 1/3 speeds, cause when they are going faster they cant hear you cause of own engine/propella noise.

But they also go in at full speeds (if they are sure about your location)

enigma!:

Well this is an awsome game but i have just found its problem and thats the defense of the sub. I can see how asdic from a far range can find a sub but as soon as asdic is close it should not be able to see a sub that is submerged. 2. with hydrophones they should only be able to find you only if your engines are on and if you are moving. and this is true to history. However in this game they always have a blip of where you are on your screen. This is not real and i hope you guys get rid of this in multiplayer. if you sit back and think....what fun is it being a sub and not using your ultimate tactic of submergence when you are always on hydros and asdic. IF YOU ARE SUBMERGED AND ALL ENGINES ARE OFF AND RIGGED FOR SILENCE there should be no presence on the asdic/hydrophones screen. Now holding true to real life....if you try to surface the boat this would cause sound which then any attacking destroyer can have another shot. Adding to the constant radar blip of your ever persistant presence, all a destroyer has to do is wait above the dot and sure enough kill you when you need batteries and or air. I believe that if a blip does show up click on the radar screen which marks the spot. After long enough without kills AND A DOT ON THE RADAR SCREEN your persuar will go off. Does anyone here agree with me?

sorry to bitch guys just wanna see a little more strength for the subs...and in this case it is passive strength!

Actually, dont bitch at me, im a player like you

When you move at 1/3 speeds and the DD above you is running slow or stopped he can hear you, and he will have a BLIP on his tactical screen (this is not a radar, thats just how it looks)...

If he is going faster then his BLIP will fade out, just like it does if you cut your engines, then the DD will only know 'last known position' and that is ofcuz where he is heading to DC you.

if you think ASDIC cant pick up silent subs, then you should watch DasBoot

East told me once that the AI will give up on you after ~10 of silence from you (10 real life mins) and assume your dead/gone. (i havent really tested it myself yet)

more slow, keep changing depths, monitor the DD's speed when they are running ~30knots you can speed up->slow down->speed up->slow down. and also do the same for a few secs when they depth charges you.

And if you think the AI is tough, then just wait for MP to launch and get some human controlled enemies

ps, Im sure East will be here shortly to correct everything I said that may be wrong

Jesper ...no man i wasnt bitching at you or anybody...you da man. Speaking of asdic.....it is true....in real life asdic only worked from far off distances due to the cone reception offf the bow of the ship...due to this cone, the ship can only see to a certain depth that is if you were deep enough and the cone was over you that they would not be able to see you. Man i wish you were here in person....i could show you alot easier and i know you know what im trying to explain...however yes I agree from far distances the asdic can pick you up...the closer it gets it can not...and that is a fact. I dont know why im bitching so much i guess the true test is playing a human opponent on the net...leaves room for human error on both sides. Jesper you have been an awsome help. Well just have to wait till multiplayer.

Hey Mandingo,

You are dead on in your description of asdic, hydrophone operation. It is also exactly how we have it set up. Asdic can only detect to a certain range before the cone misses you. Hydrophones work based on relative speed (yours and the contacting vessel). The only piece you have overlooked is the guy plotting the contacts.

Your last known position will be maintained in real-life - including predictions of where you will be after a certain period based on speed, heading, etc. - and we keep a "last known" position around. You'll notice that if you are going fast, a submarine doesn't upate, it just get's fuzzier and dimmer.

You can evade but the trick is, like Jesper mentioned, to monitor your enemies speed and use yours accordingly. Change depths (<>50m) frequently and change heading frequently.

Welcome aboard!

ok guys...hate beating a dead horse but.....say if im evading and they send depth charges and miss....after the depth charges explode does that give me a chance to head at flank speed. I heard when charges go off there is a time period that they can not hear you. If this is true how long is that time period that i can haul ass out of there and cut the engines to silence again. Sorry but you guys are helping me out...gotta know this stuff

A few secs... depending on, how many charges that is dropped.

I calc with 1-4 from the first explosion.

Now your next question is how I can know how many that is dropped.

A: if youre close to the surface you can hear them lanuched from the ship(s)

B: use spectator view

C: take a guess and hope youre in luck

AHHHHHH! GEEEEZ its getting to me....i cant evade or ditch i keep going at 1/3 speed...i speed up....i cut engines you name it, i just cant get away from those damn destroyers! Ahhhh im about to give up on this! huh

Why run?

Just sink them and all your worries ends,
