Default How to evade ASROC (effectively)?

Hi all. I have played the converted 688i/HK mission 1 on Dangerous Waters with RA 1.48. The mission is about killing Viktor II, then Krivak II, and sending fireworks (TLAM) to Cuban armory. This is my story. My problem is killing Krivak. When I shot her, she counterattacked with ASROC (Silex). I tried this mission twice.

1. Frist trial. I was sunk by her Silex surprisedly because there was no "missile launch" warning, just TIW warning when the torpedo was entering the water.

2. In the second try, when my torpedo was about 5 nm from her, I fully retracted my TA, then slowing down, waiting the TIW to came. When the torpedo entering the water, I immediately turning away from the TIW bearing and flanking and dropping CMs on turning point. I stopped flanking at 1,5 nm from datum, and it seem succeeded. Restreaming TA, reguiding my fish, and finally I killed her.
So my question : Do you have a better/more effective method to evading ASROC? Any constructing advice is welcomed.

In my opinion its completly wrong

1. After your attack (torpedo or UGM's firing) you should move away from your position. You should do this as fast as possible because Torpedoe can be detected from long range. So recommended to go minimum with tactical speed (19 kts for TB-16) or faster (up to 25 kts)

2. Do not cavitate!

3. When your torpedoes are close to target - slow down to tactical speed 15-19 kts. It will allow you to make some corrections

4. Don't wait to TiW - its always too risky. Better is to change course and run away with high speed.

Krivak launch missiles from above water - so you cannot hear "underwater missile launch"

How long/how far I must go from datum? I tried the third (with show truth on, just for testing). I shot the torpedo off bearing and resteering it (hoping to gave false torps bearing), and I went away from datum. When the torpedo approached her (+-3,5nm), she still shot on my bearing even if the torpedo came from different bearing

Ofcourse, I even made cavitation-speed-depth graph for LA fleet III.

So we can not know exactly when does she start launching that weps?

Here is my gameplay from this mission - i played on Collins



Attack on Krivak after 44 minute

(Layer was at 268 m)

Torpedo were launched under layer and not straight to Krivak. After launch i changed course and speed - under layer.
When torpedo was ~5nmi from me and enemy - iv'e changed torpedo course so i was on differend direction than torpedo.
My sub go litle above layer for solution correction.

@pepe
Thank you for the video. I am sorry for the late reply, because I am bussy a few days ago. Btw there is still TIW message, what is the source (based on replay)? Is it from ASROC or conventional torpedo (beacuse your range and the enemy is close). And why did you choose to attack from close range instead of long range?
