As per stock settings, from 1 Jan 1938 to 31 May 1941 the Soldati destroyer is equipped with two broken K-gun projectors. Try installing Cerberus62 Corrected Depth Charge Projector which replaces them with similar (yet working) projectors ;)

P.S: download link in the last post

Thanks gap, Ill install this mod right away and see if if works.

Keep us informed :up:

I just did another shallow water test with the K gun fix, and the Soldati seems to be happy to discharge ordinance with, hmm, relatively poor accuracy. :hmm2:

I will run a deep water test soon, to see if the German Destroyer will actually make some attempts to help.

OK, after the deep water test, it yielded the same results, bearly any action was taken, the German destroyers made no attempt, they just performed what looked like an attack pattern, but they dropped no depth charges, I am beginning to think that the German and Italian destroyers either only have a passive hydrophone or that they are not programmed properly. :shifty:


From what I have seen the German Destroyers just stop and idle when an enemy is near.

Even the Montecuccoli Light Cruiser made more attempts than the German Destroyer, They Cruiser made a single pass, it was interesting to see a Cruiser depth charge a submarine though :D
Generally, they seem to avoid the submarines, but once enough destroyers were sunk it decided to come in, once, then it fled, to hang around the out side of the group.

:up:

your tests are very useful for tracking down broken equipments, V13dweller, please keep them on. :up:

Nontheless, in order to undertand what is going on, we need for more information:

what date your last test mission was set to? And what about destroyer's veterancy levels? Have you update IRAI to the latest version?

Both Soldati Class and Type 1934A destroyers are equipped with active sonar and radar, but they use different models with different specs depending on date, and radars are absent till 1940-41 :yep:

The year was 1941 and the date was December 1st, and I only downloaded IRAI a few weeks ago, so I expect they have not released a new version yet.

:hmmm: This is the last and younger then few weeks. :salute:

Oh, thanks Navuhodonosor :D

Ok, after the deep water test with the newest version of IRAI the German destroyers are now using their depth charges, albeit with the shockingly bad accuracy as the Italians before.

And for some reason the British subs fire ALL ten of their torpedoes at once!
SO they run out without a hit in most cases.:huh:

After an hour and fifty three minutes, it was the same chase and depth charge with appalling accuracy, with no British losses.
But a German and an Italian Cruiser had a collision and sunk with all hands lost. (No lifeboats)

Glad I helped:03:

Soldati class destroyers are equipped with better SONAR starting from 1 Sep 1943 (just before they switch to neutral) and better RADAR device since 1 Jan 1944 when they are on the allied side:

As for Type 34 German destroyers, dates are 1 Jun 1943 for improved SONAR, 1 Sep 1942 for improved RADAR and 1 Mar 1943 for an even better RADAR device. Also note that these destroyers are equipped with two identical RADAR's, though I am not sure how this fact would affect their hunting abilities:

I suggest you to play with mission dates and see how improved sensors will affect destroyer's depthcharging accuracy :up:

I had already pointed you to the right IRAI version, here, but probably you missed my post ;)

Letest IRAI revisions gave Allied destroyers intelligent and realistic strategies, but without the pinpointing accuracy of earlier versions. Now anti-submarine accuracy relies much more on crew veterancy levels, crew fatigue and different sensor's effectiveness, hence making enemies increasingly dangerous as the war goes on. In general, testing reports by many IRAI users have been favourable to enthousiastic. I don't see any reason why IRAI should use different settings for enemy and friendly units. In other words, I am sure that the lack of accuracy you are reporting is to be blamed to their early war poor sensors. As I suggested before, try changing mission dates :yep:

This is a known problem: SH5 collisions detection is not up to standard :-?

IRAI improves a lot AI sub strategies within the strict limits imposed by the game (the same can be said about planes). Your test could demonstrate that it is still not perfect, but I ignore wether there is still space for some improvement by TDW, or not.

OK, I knocked up the difficulty to Elite of both the subs and ships, the date was 1st of September 1943, and it seems the that German Destroyers are making very good and precise attacks yielding good results.
I am going to confirm any good news on the Soldati, I am yet to see it accurately attack a submarine.

:up:

did the new date setting change anything with AI sub's strategies?

Keep us informed ;)

I am noticing problems with IRAI, it seems to have taken away the destroyers ability to attack head on, right over the submarine, making most depth charge attempts useless, I have even noticed this in the story.
I do believe that the year has affect the ships ability find submarines, the German type 1934 is making attempts to bomb the enemy subs, it proves more fruitful than the soldati's attempts.

Without IRAI, the ships go head on and usually yield many hits (Speaking as the British Subs on me) It seems their tracking systems are more adept than the German and Italian destroyers in the early war time frame, but even with IRAI, the British ships never seem to land a single hit on me, I even have enough time to zig zag until I reach deeper waters to dive.:hmm2:

I believe that the dates may have made the AI subs more adept at tracking the enemy ships (Including my submarine) but they still fire off all ten torpedoes (I know this is unrealistic) at once, in a line and if they miss, they just keep trying to attack, but with no ammunition.

hmmm if you think you have found any flaw in IRAI, you should report it to TDW :hmm2:

Also, it seems once the Soldati destroyer fires it's starshells, it's guns no longer track the enemy, and then it just gets sunk by other warships.:06: For example, the Admiral Hipper cruiser fires its guns to launch starshells, then guns stay in the upward position and not track enemies.
I also noticed this on all the other ships that fire star shells.
And do AI subs have Fuel/Battery limits?

I just made another test, but it was German Submarines versing the Ark Royal Fleet carrier at it's maximum speed, just to see what happened, and the German Submarines, like the British ones, the submarines fired all their torpedoes at once, then just fled from the scene.
I am not sure why they do this, they fire all their torpedoes without reloading, they just come out in a continuous stream.

I just ran another test, the date was 1943, 1st of September so the Italian destroyers had their best Sonar, and yet again, there was little no no action, it was just a cat and mouse chase that would not end.
I had the destroyers set to Veteran, and the Submarines set to Veteran.
But their was little action.
