Practical torpedo evasion

Barleyman · 11-18-17, 09:34 AM

Now that I've got a bit bored with the moderately arcadey Cold Waters I felt like going back to DW for a while. I got the DVD and printed manual.. Somewhere.. But I guess I might as well as buy the steam version instead of trying to locate the correct box in the garage.

So about torpedo evasion. I've seen the generic guides which more or less say to drop a noise maker and clear datum at an angle. Too bad you die that way. In CW you can see how difficult it is to evade a torpedo even when you have a perfect eye of God view of the situation. In DW you have none such unless you do a TMA on a live torpedo bearing down on you.. Good luck with that.

So, has someone made a guide on how to do it with what you have in the simulation? I presume you should work with the active intercept tool to determine if the torpedo is bearing right at you or veering to a side to go around a noise maker?

I just wanted to point out there are other options besides Steam.

If a torp has already aquired you in DW your options are limited. Drop counter measures, change depth and heading, go to flank and keep your fingers crossed.

Its much better to jink as soon as you hear the launch transient. One move I've used in the past is to jink towards the transient bearing and offset it about 30-45 degrees. You're changing the bearing rapidly and also closing on the platform that launched at you, hopefully you can put the torp behind you and travelling in the wrong direction when it goes active.

This is kind of the opposite of a "side step" where you change heading but try to put some distance on the other sub.

No shame in using auto-TMA in a torpedo-pinging situation to try and figure out where it is. Too many things going on for you to just focus on that. When the torpedo is launched, you may be able to see it on the broadband. If your sonar has a waterfall, you can watch the track of the torpedo. If it's maintaining a constant bearing (or pretty close to constant), there's a good chance the torpedo is heading straight for you. If it's blatantly veering to the left or right, odds are it was not shot at you.

The running at an angle is meant to minimize your active sonar cross section with respect to the torpedo. The optimum angle depends on torpedo speed and your evasion speed, but the ideal angle is around 120 degrees away from the bearing to the torpedo.

That's what I meant by the running at an angle. It doesn't work if the torpedo has made you.

Or..

You'll notice this was Chazley back before he learned how to shave.

Also before he got the camera properly focused on the paper..

Anyways, the problem with these video presentations is that you can summarize the important equations in a web page that takes 2 min to take in instead of watching the whole 17min presentation.. But yeah, that's what skipping is for to get to the good stuff. But a decent presentation none the less! I just wish USN used metrics

In any case that's also a bit besides the point, you're outrunning the torpedo by brute strength, not evading it.
Do note that this is absolutely no help on ASW missile torpedoes and/or helo torpedoes. In CW you *can* actually evade them but then again you have perfect situational awareness and still you can judge your turns wrong and get whacked. I'm using no knuckles mod, I don't think they really exist, do they?

I was speculating in OP that you might be able to do similar evasion on keeping your eyes peeled on the active intercept to judge the torpedo movement.

I actually did take a shot at locating the game disk and more importantly that spiral bound manual. No joy there but now I have more room in the garage and shortlisted some boxes for "recycling".

The game was cheaper on steam for what it's worth. Let's see if I still remember how to play. Hah.
