Personally, I would like to see the Rod Antenna up out of the Tower about 1 meter and not extend any higher, even when srufaced.
If the Antenna actually effected the communications radio and public radio it would be a different story.
Would be nice to be at periscope depth and have the Public Radio stations working if the Rod Antenna is extended.

Sounds like you are using your Observation Periscope when attacking?
If you go to 15m or more depth, the Rod Antenna Wake and Splash stop.

Beast, can you point me to the exact entry in the uboat.sim file where the radio rod is located? I'd really like to get this thing lowered. I see radar detector, RadarDF Loop but no Radio Rod or Radio Antena in any of the files.

Hi !

Torpedoes detonated only after a running distance of 300 m, otherwise the boat would have jeopardized their own !

I was going through the English Channel again this past weekend (heading west to my patrol area). The weather turned foggy (navigator said "medium" fog) as I was sailing somewhere west of Calais when two destroyers got the drop on me in the fog again.

Had to crash dive and evaded them for about 2 hours game time. They eventually lost contact and returned to their patrol patterns but it made for some scary encounters, not to mention they shot me up on the surface a bit before I could crash dive.

My question is am I stupid to try to transit the English channel with IRAI escorts out there? BDU advised against it saying it was mined but I just don't want to go all the way around England to the North. Takes forever.

My second question is should I have radar detection in 1939? Maybe my sub isn't equiped with it yet but I'm guessing that's how they found me and radar detection would have helped me evade them before they got within visual range in the fog.

I'm using Real environment revision 2. The Medium fog in RE seems a bit too heavy for my liking. Are there any submods that make the medium fog not so foggy?

Thank you... i made a movie and if i knew that you know so much about torpedoes i would give you the rol of the ,,torpedo man''

1) i never go to the English channel... the irai it is so evil that i do not stand anny chance to pass by there

2) yes... try this one:

Same for me I never transit the English Channel either. It's to risky best I'll do is stay at the mouth of the channel looking for some targets.

You can transit it. In good weather that is. But when you get spotted by a Destoyer your as good as dead since its way to shallow.

Thats why I had a laugh on.. crash dive and evading destroyers in shallow waters

Yep. It was a bit shallow indeed. I immediately had to order a reversal of depth to keep from smashing into the sea bottom but the DDs had opened up on me at short range with their 5 in guns so I had to get under quick...hence the crash dive. I think I was lucky because the sea was a bit rough so their sensors were not as sharp. I dove down as deep as I could go and went silent. They made one or two DC runs on me but none of them hit home.

For anyone wondering I've customized my IRAI difficulty file to 85-95 for escorts on all sensors. Does anyone find this setting too easy? I thought 100 was too hard but I might increase the difficulty just a little bit.

So my lesson here is NEVER GO THROUGH THE ENGLISH CHANNEL. Noted...

i do not understad how you can excape with irai by default from 3 destroyers... i had last time 3 on me... i managed to sunk one of them and took me 1 day game to escape from 2 others.. they putted a lot of depth charges on me

First, it was only two destroyers. If I said 3, I was mistaken.

What are your evasion strategies like?

Like I said, the weather was crappy and the sea state was high which works in your favor as the DDs have a harder time hearing you in high seas. I had about 60 meters to play with. Secondly, I have had a lot of experience evading elite escorts in SH4 using the Triggur Maru mod. Try it sometime. It's scary.

This is my strategy when detected and the DDs are approaching.

1. Crash dive and order full right or left rudder (usually doesn't matter)
2. straighten out my course and order ahead slow (1) + silent running
3. Usually at this point they have come back around for another DC attack. When your soundman calls out "Wasserbomen" order ahead flank and make another drastic course change. After about 10 seconds stop engines and coast. You should be fairly deep at this point. 100m if possible (deeper the better..."that's what she......"nevermind). If they still have you pegged under active sonar (pinging) repeat step three until you're out of active pinging.
4. At this point, I monitor my sonar contacts and when the DDs are moving away and their stern is facing me, I go ahead slow for short periods of time. As soon as one of the DDs begins to come back around (when I hear "warship constant distance") I cut engines again. (I still use sonar contact lines because I believe it simulates the help you would get from your sonarman)
5. Repeat step 4 until you've gotten away from the original position. If you've done everything right, the DDs will be looking for you where they think you are (usually where you dove) and not where you are. As the distance between you and the DDs gets greater you can order higher speeds and still remain undetected.


I suppose its possible that I overwrote the IRAI files with another mod but I don't think so. You helped me get my mod order correct so I'm pretty confident it is right. I'll check when I get home tonight and post it.

No you did not said 3 dds... i dunno why i was suposed that you said 3... then my tactics are the same with yours... i do not run 10 seconds after wasserbomben... i run around 35-40 after the last one... because i use the TDW mod wich cut the DDs sensors for 45 seconds when is noise in the water... i supouse that maybe my random factor from IRAI si close to max almoust all the time in my game and your is maybe close to minim (you are lucky)... and it is not other mod that overwritte the irai in my mod soup

Could be. I also don't know if they were novice, hard, elite, etc? I guess you won't know that unless you start looking through the game files.

I think it is the time that we must to open a thread and all of us to come there with ideeas and with advice from ours game experience to try to build an perfect startegy to defeat this evil IRAI of TDW... now i am afraid to attack an convoy each time when i spot them... it is like lottery.. i dunno if i will escape one piece after... and i do not want to speak about when i am forced to hunt an capital ship or an aircraft carier.. we all togheter we will defeat this irai for sure (even if TDW will try to add smoked depth charges or i dunno what mortal weapons on the DDs arsenal )
