Default How to make escorts more accurate

Hello I want to know how to improve escorts depth charging accuracy because in my game escorts can't drop depth charges accurattly below 120m. Because of that its very easy to escape from escorts

Are you early in the war? I think they get more accurate with time regarding depth. I just started playing again after about 10 years so I'm not absolutely positive about that.


Trivia info: At the beginning of the war u-boats were limited/ordered not to exceed a depth of 90 meters. They actually had no idea how deep they could safely go until a depth gauge malfunction occurred on a boat (don't remember which one). They were trying to get deep but the gauge was reading the same depth. A crewman cleared the problem and they were at 140 meters. The word got around and other captains began pushing deeper to get under the British depth charges. The Allies started the war with depth charges that couldn't be set deeper than 300 feet. It took them a while to discover the boats were going much deeper than that so they changed that setting in increments--450, 600, 750. I don't have great info on dates for the changes unfortunately. I once saw a picture of a Tear-Drop depth charge and it had a setting of 900 feet on it.

This is probably the oldest still existing SH3 issue and as far as I understood there is no way to fix this completely. Which mod are you using btw?

I am not sure abou the depth they were diving I found this source

The theoretical crush depth of the Type VIIC was 280 - 375 meters, depending on which figures are used. Design depths from 120 to 150 meters are published. The Germans generally used a safety factor of 2.5 to get design depth and they tested the hull at a safety factor of 1.5. The maximum safe depth for the VIIC was therefore between 185 and 250 meters. The problem is that most of numbers published do not specify the applicable safety factor, so it is difficult to come up with a precise number for theoretical crush depth. The actual crush depth varied from one boat to another anyway since the quality of the materials and the workmanship varied.

BTW, there was a project for a VII C 42 which was to have a design depth of 200 meters using armor plate as the hull material. This gives us a maximum safe depth of 330 meters and a crush depth of 500 meters. Most of the other U-boat types only had a design depth of 100 meters, so their test and maximum safe depth was only around 170 meters, but many went deeper.

The Type XXI was designed to have a design depth of 135 meters, which gives a crush depth of 340 meters and a maximum safe depth of 225 meters. However, when the finished product was tested, there was a minor problem in the design which reduced the design depth to 120 meters, so we get a crush depth of 300 meters and a maximum safe depth of 200 meters, rather similar to the VIIC. The deepest test dive was to 220 meters.

I think later on (war time line) depth charges are able to explode deeper.
Open DC.dat in library and you’ll find all kind of Mark type and values has to be inside.
(Don’t remember the exact .dat name)

That's good info. Much better sourced than my my material which is solely from aging memory banks Thank you for the post!

Very interesting, indeed! The pre-war diving depth for deep dive trials was 50m. Acc. to some Uboat war patrol logs, this was still the practice until end 1940. The B.d.U. order for deep dive trials to be done at 2A-meters (160m) was not given until Jan.1941.
