I don't get it with Taskforces...sometimes they act OK and hunt you don't like a dog after sinking a Cap.ship (VERY rarely in my case), but mostly they just break formation , move around and doing nothing.

See my topic about another example of bad DD behavure:

Something's still fishy with the DD's

Mods used: RuB 1.44, Hollywood, latest convoys mod.

I did a test with u-505 mission and now i think that something is really wrong .

first i tried to shink the carrier with two electric torps , but failed.
the scorts don´t react well and continues his course. :huh:
i know tha electric torps don´t make trail and i decided to surface an see what happens.

Only one destroyer start firing and running to my position, so i crash dive. but the destroyer was unable to reach my position despite i full raise the periscope and the snorkel. he was circling and dropping charges at 3 km :nope:

i decided to aproach to the destroyer with the mast out.

some planes passed over me and nothing, Afortunately a plane see my periscope and did the first attack run but after of several minutes .

only in this moment the destroyer change his course and start to chase me, i left the periscope and the snorkel out and i was able to fire two torpedos to the destroyer , with one hit.

finally i was destroyed , but with a very bad tactics. if i launch the torpedos and crash dived to 100 meters in silent running perhaps i could scape easly.

And only one destroyer come to chase, the others continues his course.

It was suposed that all come to me looking for destroy me, but not ..

could be that some mod , or my instalation makes dds stupid or confused :roll:

The early and mid (maybe till 1944) war DD's seem pretty deaf, especially at wind faster than 7-8 m/sec. I regularly attack convoys and leave undetected. Even being detected I usually manage to escape unpunished, escorts (elite!) make one more or less precise DC run and almost always loose me which is rather boring and unreal. History tells the contrary: usually uboats suffered n-hours DC attacks even in early period of war. I tried to change AI_sensors.dat and Sim.cfg, but did not succeed. How can I tweak sensitivity of hydrophone?

There is a value that seems to be the sensitivity in AI_Sensors.dat.

It is about .01 to .03 for all seven passive sonar. try using a bigger number. they end in the letter "P" such as search for "QCEP" =(0.027) It follows a word called "sens" in hex single point float.

Also in Sim.cfg try these.

[Hydrophone]
Detection time=1 ;[s]
Sensitivity=0.03 ;(0..1) make bigger
Height factor=0 ;[m]
Waves factor=0.5 ;[>=0] lessen to zero
Speed factor=15 ;[kt] increase.
Noise factor=1.0 ;[>=0] ???

Mant times the DD are moving faster than 15 kt and they will not hear you. Increase this higher.

The one DD will come look for you, as an escort, moving so fast, he cannot hear you, then turns around and moves fast back to the convoy above 15 kt and no longer hears you at that speed.
