Tips on stalking the Diesels?

Are Typhoons "deaf" to their sterns? Could I have sped up to catch it, then slowed again? I'm always worried about copping a Shkval - being detected means being dead with those things!

Typhoons have towed arrays, so there is no baffle to hide behind. There is also no real reason to worry about Shkvals. I have never seen the AI fire one. These seem to be more of a human player tool/threat than anything. As far as losing the Typhoon, was there a thermal layer near the current depth of your track? If so, that is probably where you lost him. If your towed array is deployed too far out, it will dip below a thermal layer when you move at very slow speeds. Likewise, if the Typhoon transitioned the layer and you have all sensors on one side of the layer, you will eventually lose him or only maintain intermittent contact.

No, they don't.
The Typhoon class only has a hull sonar, under the torpedo room.

Edit: Nevermind, it seems they do have a towed array. First time I stumbled upon this.Maybe the older ones didn't have them, not sure.
Edit2: As I suspected, only TK17 (Archangelsk) and TK20 (Severstal') have the 'Pelamida' towed array.

It would be interesting to know if Dangerous Waters makes a difference there.
From what I remember, the Severstal' doesn't have a towed array in the game but I'm not completely sure.

On the topic of Shkvals, you should definitely worry about those. I've been sunk, or at least hit, by quite a few AI Akulas launching Shkvals at me. Not sure if the Typhoon carries Shkvals, though.

I'm also not sure how the game models AI sonar. Do they explicitly model them using a towed? Or is it just like "handicapped" so the AI has further detection ranges on the other arays?

I have LWAMI installed. Let me double check to see exactly what the Typhoons have in that mod.


EDIT: Hmm...in LWAMI, none of the Typhoons have a towed array.

I have LWAMI (v 3.11) installed too.

Did you read that from the database directly? Because I can't (I haven't the editor for the database) but... In the "Platform Reference Guide for LWAMI 3.11", an xls file supplied with the mod, under the Russia section, it says that Typhoons are equipped with a TA and they do not carry the Shkval (only Oscars, Akulas, Victors, Alfas and Ladas could be equipped with Shkvals).

I'd like to clarify these points...

EDIT: Also, in LWAMI 3.11 the range of the MAD detonator on Shkval is equal to 250 meters insted of the 500 meters in std DW. This, plus the fact that in LWAMI, AI submarines engages you much sooner than in std DW (because in std DW they first have to completly ID you where in LWAMI is no more the case) means that a an AI launched Shkval against you is "fatal" only if the AI platform firing it has a solid TMA solution on you.

I remeber that in a mission while on Russian (hostile, I was in a 688i) waters I was detected and sunk by a Victor that fired on me. He neeed to fire 3 torpedoes and only the 3rd striked (they all was SUBROC). But while watching the replay with Truth On I was surprised to discover that I was detected and fired upon by another Russian sub that was around the general location of the Victor and that I was obliviuos about (I'm not sure but IIRC he was an Akula). He fired something like 3 or 4 shkval, one at time, and he should have got a real bad solution on me because the Shkval all missed passing far from my position (about 1 or 2 nm on my sides).

But that was very scary witnessing this things running like hell across the map!
If they are well aimed you are already dead, like a Kenshiro victim, lol!

Yes, I read the Objects.eod database. The DWEdit tool comes with LWAMI. It is in he /LAMI_Mod/FileTools directory. I also stand corrected as I misread one of the database entries. They do have towed arrays. However, there are only three Typhoons; Dmitri Donskoy, Arkhangelsk and Severstal'

In LWAMI, any American sub going faster than 3 knots will be busted by Russian sensors. Also, firing at you without a good solution kind of makes sense, from an alternate line of thinking since the AI knows which units are their own. It is something like, "That contact shouldn't be there. Kill it."

I have been fortunate to never have a Shkval come after me. The only possible counter I can see in dealing with them is to remember that they are unguided and hope one is deep enough and the torpedo is far enough away that one can blow the ballast at flank speed and squeak by. It is nigh impossible to dodge a 200-knot torpedo. You would have to be at its max range to even try a course change to avoid it without a fast depth change. Its maximum range is 6NM and it needs the first mile to arm. It takes 20 seconds to reach arming distance and 1 minute, 40 seconds to make the 6NM run. That is a very small window to try and get out of the way.

Well, since in LWAMI it's MAD detonator has only a 250 m. range you have about 1 and half a minute to clear that space (with a movement normal to the Shkval vector)... Maybe still quite feasible at flank speed if you keep your head (but then you have made a lot of noise in the region and more evil will arrive)...

Well, I don't think is so simple... you sill have to consider the tactical situation, ranges in play, SSP, sensors and baffle areas as well as initial intelligence for the platforms and relative speeds...

Stewy1,

Another recommendation, keep checking your narrowband. You'll see most contacts, even diesels, in the narrowband a long time before you'll see them on the broadband. You may not be able to tell what they are, but if you're in an LA, most things with a 50 Hz frequency are bad for you (except maybe European allies you hopefully already know about).

I have DW w/LWAMI on multiple computers here at home. I tested the platforms in multiplayer to get an idea of what their capabilities are and for the American subs, cruising over 3 Knots is rolling dice in terms of detection and anything over 5 is almost guaranteed. The Petropavlosk campaign mission proves that. Anyone who hasn't modified that mission to reduce the American subs to 3 knots will trip the counterdetcted trigger almost instantly. In the instances I have not seen the instant trip, it usually occurs within two minutes of headway.
