Nah.. it was regular stock campaign and regular convoy with cimmaron tankers and liberty cargos.
As for new campaigns and ships - I wait for you guys to declare it fully tested and ready for use. I got enough my own things to deal with, can't install much of beta-versions or I will get lost if any new issue that will come up, trying to figure out what to blame - my experimental editing or new mod.

Also.....

IIRC, Running depth varies some and does not swim like a laser beam at the EXACT depth you set.
I forget what the variable is, and Maybe TDW's stuff adjusts this variable ?
Therefore your fish could be swimming under the Destroyer, or escort as they have vary shallow drafts. ( Even if the setting is to run the shallowest setting ! )

I have fired two fish at a Broadside, 600 meter shot..... One hits, one goes under.

Or maybe I imagine this whole thing....lol...
:cool:

What depth is the sub sitting at when you fire the torps ?

To stoianm:

Yesterday night I finally come across task force with battleship in it. While I was chasing them beyond detection range (but with new hydrophone mod I could not detect them as well if surfaced - so I had to dive every 15 minutes) they change course twice, pissing me off royally.

Anyway, I ordered my torpedo man to preheat eels and nailed 3 out of 4 fired torpedoes into battleship ending her glorious days.
I didn't want any more blood and decided to dive early hoping to get away with my dirty deeds.
it took about 40 minutes for 16 DD's and two remaining capital ships to locate me and they started pound depth charges at me mercilessly. I still pretending that I am not there but hull start take some damage and I had to maneuver to avoid total disaster. I've heard some collisions above me but their numbers still high. I was waiting for night to be over, so I can see better in day light if I will have to surface.
Next morning CO was about 18% and I decided to get some fresh air.
"Rudder hard to port! Extreme speed ahead! Periscope depth!"
I started descent form darkness in spiral to prevent destroyers align for deadly ramming. Periscope all way up - you need some luck not to run into one in first seconds.
If you think that depth charging crazy Russian in command of German submarine in 1941 is a picnic - think again:). That's what I left on the surface after 10 minutes of zigzagging on periscope depth and surface for a second to refresh and dive before any shells could hit me:

Nice story... this scenario is posible today... in future if you will be hunt by more than 3 DDs you are as good as dead:

1) irai32 by TDW (stil wip) is evil... if you are hunt by HK... one of them will not move and just waith to see your position and report for others
they have some fatigue time but until they decide to be ''tired'' you will be dead (this behavior is also in irai30)

2) Fix 0.18 (still wip) take care about the damage part produced by DC... now the damage produce by DC it is a joke... in future will be immersive... so DC will produce a lot of damages on you (first they will scrap yours engines in general)... after that you will be not able to move like before and they will put DC a bit more precise on you.. so you will have no chance to exacape...

In my opinion to attack capital ships will be a kamikaze mission in future (and i will say that is very realistic)... zedi is taking care to match ours campaigns with the new immersive mods and we will not have anymore missions like the one to sunk a capital ship or a aircraft career

The best tactic when i hunt a capital ship is the ''hit and run'' method... but somethimes even with this method i get caught:88)

Eventually I could hear only about 8 destroyers above me 24 hrs after engagement started. But guess what - I could not belive my eyes on tactical map and my ears in hydrophone station. Another hunter group consisted of 7 DD's and 3 cruisers arrived and joined the hunt!!! Holy crap... At this point I thought that I really not gonna make it, so I walk among my men telling them how proud i am to be their commander and serve all those years with them..
I don't know how, but another forced surfacing, remaining three torpedoes launches and 20 more hours of maneuvering finally I got rid of whatever left of them...

Periscope check before surfacing and surprise, surprise... What do we got here? Lion become a lamb, huh? They left their own for nature to take care of them.

48 hrs stand -off like this is not realistic? wow.. what can I say... If DD's will be able to knock your engines out in first couple charges dropped and they precision will be dead - on - it is UNREALISTIC my friend. Most of the U-Boats where sunk by surprise air attack and until British capture U-507 at second year of war (if I remember correctly) they didn't even know that U-Boats are able to dive below 100m which was maximum depth set on depth charges at that time. They were astonished after looking at depth dial and see that red zone starts at 150m!

So you will install all those UNREALISTIC mods and do what? How you will finish Mare Nostrum where you have to sink 4 battleships and 2 aircraft carriers heavily escorted? Oh I know what you gonna do - you will install another unrealistic mode - "Light Campaign" and peacefully hunt unarmed merchants using 90 degree method LOL.

You have all of those mods install - and you recently admit that you never even shot at destroyer. Think about it... And Mediterranean is not Atlantic - you will not find so many merchants there. U-boats sunk almost as many warships there as merchants. And this is reality, historical fact.

So - if you will have mods like you mentioned - you just can't engage them, what's the point? People got problem to survive current ARAI maximum settings. What's the point to make it simply put impossible?

stoianm 05-28-11 01:05 AM

I did not said they will become more precise... i said the DC will produce damages not like now... you are hit manny time and you have nothing... and i told you that zedy is reworking all the campaigns... i do not think that the Uboats engaged manny times DDs... or HK:DL... they engaged most of time ships... not capital ships


Little campaign reduce the tonage only... he is not changing the fact that in '39 a lot of convoys were unprotected... this is from vanilla

I can shoot a destroyer if i use the game (tdc off - lock target - unlock target) bug or if i play with no map contact update... if i play real navigation and no map contact is very hard to hit a destoyer (i mean in the time he is looking for me)... when i hunt by surprise i can shoot a destroyer also

Irai is not at maximum... irai have a min and a max number... when you play you never know how the DDs will be... this in combination with the fact that you do not know if they are veterans or poor increase the immersivity.. i understood that in RL if you are hunt by 3 DDs excape chances are close to 0

In first war years if you dive at 150 metters you will be not hit by DC... i think oscar already tested this and is working

If I would got hit - I would sink. Depth charges were exploding around me but not dead-on me. You achieve it buy be quiet (not even minimum speed in quiet mode - what those 400 meters will do for you if DD's got it covered in less than a minute - that's most common mistake people do - they run their engines after attack trying to "get away".) and changing your depth as explosions are getting closer to you.
Sorry for being smart ass with you but let me give you some theory.
If you are trying to hit some target with artillery shell - you have to solve two-dimensional problem (flat surface coordinates of horizontal plane).
If you are trying to hit some target with the torpedo - forget about depth-setting it just change damage amount - but to really hit you still have to solve two-dimensional problem (flat surface coordinates of submerged for couple of meters but same horizontal plane).
If you are trying to hit some target with depth charge - you have to solve three-dimensional problem. You have to pinpoint location on two-dimensional horizontal plane. And then you have to submerge it to more or less precise depth that bring out third dimension. And if it matter of 5 meters (that how close explosion have to be placed to induce real damage) in 150 meters range - I would say you have to solve it pretty much precise.
That what's makes precision depth charging extremely hard and that's why in WWII they was trying to solve it with AMOUNT of charges dropped (hedgehog and other things invented) - because it was extremely difficult. Major goal was to force sub get out of the water after running out of oxygen. And if sub will be hit by depth charge in process - fine.

So - again - making DD sink your sub in first 30 minutes of engagement -makes it extremely unrealistic in my humble opinion. But it's a game - people free to do what ever they want with it, right? :)

stoianm 05-28-11 01:55 AM

I agree with you... but like now when they put tons of DC on you and you are new like you just pop out from box is not ok... i was asking a german friend of mine when he told me that manny submariners died on sea: if they said that DC do not affect to much a uboat... how died so manny people... it is hard to belive for me that all of them were caught by surprise on surface attacks:hmmm:

Off topic: i like very much your town... i made once the mistake to go from Pheonix to Flagstaff on that shorcut highway... i was with a truck charged with 80.000 pounds... wow man... what a mountain... i almoust kill my truck but the view was stunning.... if i will change my town one day Pheonix is a nice place to live there

I would recommend you "U-Boats, The Illustrated History of The Raiders of The Deep" by David Miller.
At the end of the book he got list of virtually every sub commissioned with detail info when where and how it died (or last 'till the end of the war) even including data on enemy units that sunk them.
About 40% was sunk by the enemy ships. I would say about half of them were rammed, gunned or destroyed by any other meanings when at surface (in the beginning of engagement or after having to surface running out of options). That's leaving to depth charges deaths like what - about every 5th U-boat? You can also subtract from this amount boats that got crushed by water pressure being unable to control depth - but it still not direct hits by depth charges.

No one is arguing with fact that majority of German submariners died at sea. They suffer heaviest losses than any other military branch I guess.

Misconceptions are very common here (nothing wrong with it - we all learn this way or another new things for us, right?).

For example - I recently read description for large popular mod that adjust boat and weapons specs to historical values. Very good mod and lots of effort spent by author and that's really appreciated.
But I come across one dilemma that he had - how much to make radar's range. For that specific model surface ships were 10 km and aircraft were 30 km. Because it is impossible at this point to make two ranges separately he desided to make it something like 10200m to be "fair to fellow merchants". Huge misconception in my opinion. Radar was active device - who cares of using it to look for merchants (or God forbid warships with all their radar-detecting equipment)- it never will beat passive (and therefore much more safe) hydrophone? Major reason behind radar developing and employing on U-boats was anti-aircraft defense. If Karl Doenitz big enough proof - he even issued order forbidding commanders to dive while aircraft is approaching unless captain were sure that he can reach depth below 50m before aircraft arrives overhead. Aircraft attacks cost at least 50% of total U-boat waffe losses and was major headache for Doenitz.
I would make maximum range for radar - as anti-aircraft defensive equipment at the first place.

Another thing - I would concentrate on better precision (and damage) of bombing by aircraft rather than DD's deadly depth charges explosions that will rival nuclear testing in Bikini Atoll :haha:. That would bring it closer to reality. Aircrafts in current version of IRAI so sluppy - I am seriously considering stop crash-diving and just ignore them (joking - those pesky airplanes will inflict lots of hull damage with their mashine-guns anyway).

Man, one day I was driving 80 000 fully loaded myself and was talking on the phone and missed moment when I have to downshift... 15 minutes later when I saw smoke coming from reefer brakes I had no other choice but surface the boat and surrender.... I mean I ended up in escape ramp and My rig just sunk into 2-meter deep gravel after it finnaly come to stop. And it was Friday night and I had to listen to all those radio comments form fellow truckers.
Oh.. it was very romantic time of my life. We drove all over the country with my girlfriend... LA to Boston in 3 days - I was killing myself.

What do you mean?

I only agree to take out actual distance. But bearing and type of ship - it is provided per sonar guy in real conditions. He did not graduated Harvard like yours (I saw that post LOL) but any average-trained sonar guy know how to recognize sound of warship or merchant. So it is provided that you have bearing and identification at any given moment.

By the way, before I forgot. Can you ask TDW if it is possible for submarines make sound as well? You can see sonar contact but when I go hydrophone station - I can't hear anything even at close range.

it is a bug that pop up somethime... most part of time you can hear engine sound on hydro

By map contact i mean before you start the new mission (in bunker) to check '' no map contact update'' ... like this you will not have any ship simbol on your map... you must to use stadi or RAOFB wheel to track ships datas... then you will understand why i like so much that fast 90 method
