Kind Regards

Let me know how it works. There's a lot of adjustments that can be made so details on what does/doesn't work for you are welcome. I'm willing to try to help you get the result you want.

Please include:
1. date of scenario/campaign.
2. Weather conditions when testing.
3. Number and type of escorts (DD, DE-Sloop), Corvette, Other.

Hi Mate

Sorry for the reply, bought a new PC and have been getting everything setup for SH3 took forever but now its running looking good.

Hey did a patrol in Feb43 attacked a convoy in North Atlantic very calm weather
escaped initially but when shadowing on the surface putting contact report and was detected by an escort dived to about 70 meters when he was pretty far off was detected again by sonar and I could not shake him no matter what I did, went dead quiet, released bolds, deeper and deeper ended up at 260 meters still couldn't shake him ended up going below max depth and imploded at 300 metres!

So the mod works that's for sure, might have to go to the easier one! LOL.

Always after 44 that's the usual scenario so having such deadly escorts in early 43 was a unpleasant surprise.!!

Kind Regards

Yep. That certainly is a likely scenario in calm weather

. I've been using the 2500 for a while now and it can be a real buggar to get away, especially in calmer weather conditions.

A little more detail regarding this nod for you. Passive sonar is not affected (I didn't touch those files). However, it can appear to be more effective due to how the game works with the new active range. If you allow the enemy to have a broadside aspect for a long time at ranges ~1500, he may start pinging when without the mod he would have sailed merrily on his way. With a narrow aspect--not so much.

How I get away is by keeping the escort in my baffles between 160 and 200 degrees. You'll still be getting pinged a lot but the chance of detection is much reduced. I (typically) maintain 2 knot speed. Dropping to one knot doesn't "seem" to make much of a difference as long as I'm silent running. Sometimes I drop to one knot (rpm 50) and it can make a difference but part of that difference is due to staying under his sonar cone at close ranges. You can also keep detection chances low by keeping him in your bow profile of 340-20 degrees but the problem there is obvious. You'd closing the range to him and when close, aspect doesn't matter. He'll find you.

The worst case scenario I've had so far was when facing three angry escorts--a DD, Frigate and Flower Class. The problem then becomes their different turning radius'. It makes it impossible to keep them all in your baffles and one will almost always get an angle on you. And those three escorts were persistent! They ignored the convoy and stuck with me til they were out of depth charges. It took four hours in real time to get away--9 hours game time to get away. I was more than happy to use compressed time when they had quit dropping depth charges

!

Bottom line: you'll hear a lot more pinging but it doesn't always mean they have contact. Your crew will tell you when they do ("Enemy is pinging us Sir!"). The 2500 mod is tough but that's what I am now using by default. If I know I have limited time to play, I replace it with the 1700 meter version. And don't forget enemy crew quality--the Great Unknown. I'd say it is a safe bet the escort you were pursued by was Elite and that makes a HUGE difference!

Anecdotal information: An interesting point is that in real life, flat calm seas were considered poor for sonar. The reason being, disturbances caused by explosions and ship wakes did not have any wave action to disperse them so sonar indications were confused. Ship wakes actually can be strong enough to give an active return while in passive create Lots of noise. Best sonar conditions were typically sea state two or three. Not that it really matters to the game--just some info.

If you want, I'd be happy to create another version of this mod with an intermediate range. It would be easy to split the difference so three versions would be available--1700, 2100 and 2500. And for others who may interested, while I created this using GWX, I see absolutely no reason it won't work with other mega mods.

Finally @ Eastwa--Congrats on your new computer! Always nice to have some more power under the hood!
