remember depth is your friend when being attacked!

it's the exact oppsite in 1939....

My old man was a ASDIC Sonar operator on a Hunt class destroyer.
HMS Inconstant and another destroyer HMS Wilton.

one of these was responsable for a U-boat sinking. I can ask him about the range of British sonar when he was serveing.

I think secretly he wats to Hijack my PC to play SH-III and SH-IV.

back when i was a school kid my old Amiga was hijacked for Silent Service II :)

So tomorrow I will ask him about sonar range

Ask him specifically if they were capable of using their hydrophones to detect a drifting submarine (screws not turning) if it were down at about 100+ meters depth.

i think we have already determined through that they were using active sonar ASDIC randomly and just happened upon me.

Though I'm sure Pappy55's response will be interesting indeed, something you gentlemen need to know regarding SH3 is that simply plugging real-life data into the files does not necessarily yield a life-like performance. This is certainly true of the sensors as well.

ASDIC/Sonar was quite susceptible to water temperature which could cause the beam to warp or dissipate rapidly. This variable is not represented in SH3... Though you can use SH3 Commander to offer a representation of thermal layers, even then it does not offer a true representation of beam geometry changes.

(Just as I can't see a way to keep ASW ships from banging away with the active sonar above 15 kts... without potentially remodelling every ASW ship in GWX. That kind of extra work would be prohibitive at this stage anyway.)

With all possible due respect to the ASDIC operator's real-life service, it would take more than one statement to warrant another deep review of the ASW sensor package in GWX.

Memories fade or change with time. Add this and various other limitations of the objects we are working on, and you see the dilemma.

What we have now, is a working representation of ASW sensors becoming progressively more effective as the war goes on... as they did in real life. The player can most certainly survive them assuming that he adapts to them as time goes on. Though you must become more daring, run deeper, and be willing to LET A TARGET GO on occasion... GWX is certainly surviveable at the worst of times.

Furthermore, even a slight change to the sensors in GWX can lead to a cascade effect of dismal performances. I will not allow them to become a joke.

Do what you will. I'm sticking to my guns guys. We have a good thing going and I'm not going to torpedo it.

you and the rest of the team have come up with a working formula Kpt. :up:

id like to see his answer just for the sake of being that much more informed :know:

ASDIC had a range of about 2000 to 2500 yards from my research.

Oh me too. Don't get me wrong.:up:

Without looking, that's pretty much what we have as well. I'm guessing that you meant 'meters' though?

yeah prolly meant meters, i always catch myself saying yards too

yes your right meters.

I asked him about the hydrophones and he said it is possible.. Unlikley but still possible.

I have a few questions about what happened before you were found..

Were you far from your last contact and did you engage it?

I am thinking maybe you were detected in an encounter and they sent out the hunters to look for you.

I have attacked ports with only merchants in before and on my way out a few miles from land there were a pair of Destroyers comeing my way at flank speed as well as aircraft circleing the area.

Just my theory..

i was only 2 or 3 days into the patrol and had no previous contacts, this group of 3 destroyers was my first contacts of this particular patrol.

at this moment im convinced that these destroyers were pinging and just happened upon me by sheer luck.

I can confirm with certainty that ALL local ASW assets in-game are sent to hunt for you if you are detected in game.

For instance: You sink a destroyer, and within half an hour or so you are attacked by an aircraft... or vice-versa.

The AI will do its best to maintain contact with or re-acquire and destroy you once aware of your location.

Therefore, following an engagement, you must make yourself be somewhere else if you know that you are in an area that is likely to be saturated with patrolling enemy forces... such as the Bay of Biscay... Gibralter... etc etc.

Engage, and then displace.

I confirm that kpt., I experienced that too many times, Britts really throw everything they've got in the area to hunt you down, .... even if you were detected by a tiny sloop :-?

Is this certain also for convoys? Because when I attacked certain convoys I got the impression that some escorts - those close to my position - were hunting me, while others were doing their routine patrol moves. Even last night, I got detected while on surface by a Black Swan while shadowing a convoy. The sloop came at me guns blazing, but the other escorts plainly ignored me. And there were some destroyers able to reach me in no time, at their 34+ knots. Which wasn't the case and I ran away from the Black Swan on surface.
