Torpedo evasion involves spinning around in circles at flank speed.

[meltingSnowdrift]

Procedure to reproduce
Run the attached scenario in the mission editor to allow the control and observation of both sides.
This is the same scenario as used in my previous report[1]. Unlike for that issue, automatic evasion should never be turned off for the ship when reproducing this issue.
Command the submarine to attack the ship with a torpedo.

Expected behaviour
When the ship detects that it is being attacked with a torpedo, it should perform evasive maneuvers.
This presumably should not purely consist of spinning around in circles at flank speed.

Actual behaviour
Upon detecting the torpedo, the ship spins in circles at flank speed.
For reasons described in my previous report, the torpedo may fail to hit the ship despite the ineffectiveness of this means of evasion.

I too have noticed this behavior but not only with submarines but also surface ships when attacked with torpedoes. I am new to the game so not sure how to upload a scenario just yet but I was playing "Canary's Cage" when this occurred. In one case it was my submarine when attacked by FFG with a torpedo just began spinning in a circle and another case when i tried to sink LDP with a torpedo the ship just kept spinning. I hope this helps. Thank you

Is this still an issue in B1328.10 ?

[bloodnofsky]

Unfortunately it still persists post 1328.10 update. In the attached scenario the F71 Baleares it is just spinning in a circle at 30kts while being attacked by torpedo. Thank you

I've tested my save file too. While it kept driving donuts against the torpedoes already on the way, it behave differently when new torpedoes were detected. Then it tried to get way from the last known torpedo position. I would consider it as fixed.

It still happens after .10 update , please see attached file below

And thanks to bring this up. I do feel the sub warfare in CMO has a lot of room for improvement. Put automatic evasion posture as an example, before the Tiny update, the sub will turn to the course parallel to the incoming torpedo , running at flank in a straight line. It is just feel like a person evading an incoming train by running on the train track. After the tiny update (I think) the sub will take an S-turn evasion, but I would say it is just a tiny improvement compared to the original straight line evasion mode, The S-Turn is too narrow to defeat most of the torpedo’s search cone. In some of the cases, it even diminishes the chance of survival. Because for some fast speed nuk sub and a short range torpedo, running at a straight line has a fair high chance to drag torpedo out of its range, and now with a S-turn maneuver? It shorten the range the torpedo needs to travel.
I guess for CMO’s future improvement plan, we need to change how the decoys work in CMO , Submarine needs the combination of maneuver and decoys to defeat the incoming torpedo. The CMO’s decoys success check only happens right before the weapon impact, that makes the maneuver part useless in most of the case.
What makes things worse is even after the decoy successfully spoof the torpedo, the torp will make a sharp turn and initiate a re-attack at 1min – 1min half later, that's happening before most of the decoy launcher finish the reloading. Which means the Sub is doomed. Anyway this belongs to a different topic.

Right now in my gameplay, I would turn off the automatic evasion. I am doing an evasion manually. After detecting an incoming torpedo, I will shoot back with a BOL launch, forcing the shooter to evade and cut the torpedo wire. At the same time I will running at flank speed, change depth to the different side of the layer, plot the course perpendicular to the incoming torpedo. After 2-3nm, change the course and make it a 120 degree escape. With this method , I can ensure to defeat the long range wire guided torpedo in most of the cases.

Thanks, that sounds good. I'll give it a shot.

We agree on that: https://www.matrixgames.com/forums/view ... 8#p4790358

We will examine each of these reports independently. We understand the urge to list all grievances that come to mind on underwater ops, but handling items one-by-one is key to being able to manage and actually introduce the improvements we have in mind.

Cool, thanks!
Looking forward to that
