Robin and Will that is what I was trying to explain earlier to DW, the tactics are good but the DCing is not so good.

Hope DW has a nice trip

What it is the HK?

Could you tell me, what settings should I modified for testing ? I would like to make some tests. :ping:

This is the Hunter killer group which does hunt very well but does not seem to drop many DCs. Not the close escort which will stay with Convoy or BG.

I ve just found the falue of "noise factor" in "Hydrophone" section of sim.cfg file. I change it into stock value and result are quite good. The range of the sensor change accordingly to speed value.

Still have the problem, why DDs have passive sonar circle active when I am surfaced. In stock game there is no such situation. Moreover even I am on surface, the DDs could hear me :hmmm:, so I can not attack at night at all. So which value is responsible for that ????

I'm very sad to say that I had to disable IRAI, is not working good now.

Story: got in sight a very large convoy and after the first torpedoes ALL escorts left the convoy and started to camp me. For 2 days about 8 or more DD's were on top of me and in the meanwhile the rest of the convoy stopped to wait the escort to finish.. whatever they had to do. In the middle of Atlantic.

In reality, a commander who would give such an order would face the martial court. Leaving a huge convoy unprotected and delay with at least 2 day the arrival of very vital cargo at the destination .. just because they hunt a single sub in the middle of Atlantic... is beyond any imagination. The tactis now in IRAI are very wrong. Not to mention that there is no way to escape. Even under 200m and with all engines at stop, they still had a very clear picture about my location. Soon as I moved few meters, they moved too... is like they are somehow linked to my sub.

So after 2 day of playing cat &mouse I disabled IRAI and continued with the stock settings. I loaded a save from right before I started the attack on convoy and I had a relief to see the right tactic from the escorts this time. Soon as they detected me, 2 DD left the convoy and headed to my location. The rest of the convoy followed they route without breaking the formation. After I sunk 2 merchants, 1 more DD joined the hunt. But all was over 30 minutes later after they lost any contact with me. They just simply returned to the convoy and their main role, protection.

The stock tactics are correct and the escorts do the job right. The only problem with them is that they loose all contact with the sub if I go deeper that 80m. Under 80m I can sail at max speed, they all go deaf and blind. Also, the escorts are unable to drop DC's deeper that 50m and even than.. the damage is very low. So these things should be fixed, the tactic used in stock is right. They will keep the sub underwater and away from the convoy, but they will never halt a whole convoy for this, or worse.. leave it unprotected. Is a whole different story on a task force where all ships are HK's and they only purpose is to own the sub/enemy.

I am only trying the .25 on historic missions and have not tried campaign yet. I suppose this must be the Bug kicking in.

On the other hand the thing I noticed was that after a good DC run and I sustained damage and repairs started the DDs maintained contact still making attack runs but not DCing?

I found an interesting comment about IRAI when browsing a Russian forum:
http://sukhoi.ru/forum/showpost.php?...postcount=1131

Translation follows (as strict as I can):

- Before [installing IRAI], upon coming to combat area all friendly units used to be sunk at once and I used to be left alone against an armada of ships of war.

- Now, besides other mods, I also use IRAI_0_0_23_ByTheDarkWraith. And now, when approaching combat area (a few km sail), I'm lucky to sink at least one target! Before I manage to aim and take a few shots, mission ends with victory. This didn't happen just once... The mod obviously adds intelligence to units, but it seems that allies [German] get more of it!!!

well...I met a different situation recently with this mod

I sank BC Renown with a 3 torp salvo

A horde of nine DD's came over me

I was at 100 mts silent running

Well after a hunt of 6 hours I managed to escape with this mod:DL

A mix of

- dive at 140 mts

- stop

- when DC's dropped speed at 1 knts, then stop and the sub goes for a while at 1 knt before stopping

DD's dropped DC's very frequently

The only other thing I can think of is something like an ammo count or crew quality for something that random, dont know where they are located:damn:

Do you guys ever use decoys to evade the DDs?

Blockade Germany:

I came across a Nelson TF escorted by 10 DDs. I attempted to penetrate the screen, failed, and proceeded to get depthcharged for the next hour. 36 according to the chalkboard, but I my have missed a few :03:

I did manage to get away running deep and silent. Took some minor damage. It was challenging :yeah: Looking forward to '43 :arrgh!:

I haven't experienced any weirdness yet myself. Will post if I do.

I just found out when fiddling with my mod list settings, that the way you nest you add-on-mods inside MODS folder inside the IRAI folder is not JSGME compatible - it breaks JSGME "Mod profiles" functionality.

Also it may be confusing to see three new mods appear on your list after installing one.

The idea was brilliant (chapeau bas!), but potentially destructive to JSGME users. :salute:

I do sometimes when caught in shallower waters, I've seen them pass right over the top of a decoy dropping DC's but when they circle back around they pick up on me again at times. Usually takes me 3-4 decoys along with continuous maneuvers to finally get away. Other times I don't make it if there's a bunch of them after me. :)

well now

I sank now BC Hood

and escaped 10 DD's after a 3 hours chase

It looks somewhat easy to escape using the correct strategy
