Can't get away from the escorts during convoy attack....
 

I'm getting hammered by these 2 Japanese DDs, I'm playing TMO mod and the year is early 43.. attempting to attack a large convoy but can't get away :(

You using just TMO? If so the best thing to do is GO DEEPER!!

Depth?
Speed?
Battle Stations?
Repair Crew on?
Rigged for silent running?
Relative bearing fom convoy and escorts and exit heading?
Leaking Fuel?
Rear fish?

I can't shake these DDs for snot and they have a seemingly unlimited supply of depth charges.

Thank you for the information ... the data was most ... enlightening.

Silent running was on.. thermal layer was at about 130ft, I had silent running on, Battle stations active, I tried getting away various ways- but the way that ended up working was turning away immediately after launching torps and hauling butt away, surfacing when torps hit and landing a few 85lb shells on the destroyers to sink them.

Well there's your problem. You can't have battle stations on if you have silent running on since battle stations causes MORE noise then normal. Do that and go deep and you should shake them in no time.

"You can't have battle stations on if you have silent running "

Exactly.

I haven't played in some time, but seems you could activate battle stations and silent running at the same time. As far as I recall the game doesn't hurt you if you have BS on, just that SR gives you more advantage.
Course mods vary...seems we argued before if BS was on with silent running had bad effect and Duci said no...

Anyway, escaping shouldn't be a problem, go deep and hit flank when they drop, after they explode, go back to silent running. The charges should fall behind you this way. Stay as narrow as possible to the nearest escort.

As far as your sub, when you try to attack, keep a narrow profile to the nearest escort, don't be broadside to one.

Speaking of going deep... What are max depths for the subs in SH4? Been so long since I played I don't recall.

That's most concerning. You need to get out from behind that desk Admiral. :O:

I am using a Sargo so have 4 rear tubes.

I use these when taking on an escorted convoy from 3,000 yards.

This gives me a big advantage as I am already facing away from the escorts.

I can go deep and slip away at 1 or 2 knots.

If you have BS and SR on and then take BS off that bloody whistle and the shouting order kind of defeats the SR objective.

Run Silent, Run Deep, Constant Helming. turn up the volume... when you hear the splashes, increase speed, hard rudder.

Fixed that order for you. First slow and then deep doesn't make you move very far away from those depthcharges. It would take ages for you to get down there.

There is one issue with Battlestations. Your repair crew is actively making noise and I think the game simulates this with BS on. I have always noticed a correlation between being hear and being at BS.

When ever I am trying to get away I always turn BS off while running silent in order to stop the repair crew. Some mods reactivate the repair crew at BS even if you turn it off manually.
