ORP Błyskawica and ORP Grom were previously (just after building) equipped with two DC racks and 20 BH 200 DCs onboard, some authors say about two additional Thornycroft DC throwers (don't know specific model), but probably that is a mistake.
For sure ORP Błyskawica (ORP Grom was lost in 1940 during German invasion of Norway) was equipped with four Thornycraft Mk.IV DCTs after 20 June 1941.

If we are talking about ORP Burza and ORP Wicher (similar to French Bourrasque destroyers) that their antisubmarine weapons looked like this:
1. from building to 1939 they were equipped with two DC racks for 20 BH 200 DCs supply and one Thornycroft DCT for 10 BH 200 supply, but some authors say that DCT was removed in 1934 (ORP Wicher was sunk by German planes in September 1939).
2. from 1940 to 1942 two DC racks for 20 DCs supply and two Thornycroft DCTs for 20 DCs supply.
3. from 1942 to 1945 two DC racks, four Thornycroft Mk.IV DCTs and one Hedgehog.

I hope it helps you with your work mate :up:

That's more than I ever expected!
Thank you very much!

Some further questions to your superb explanations:

Do you also know how many DCs the two Thornycrofts of the Grom had?
20 like the Wicher? I model the early DCTs which you aren´t sure if they were on board with two Thornycroft Mk.I with 10 DCs each.

Do you know where the single launcher on the Wicher was positioned and if it was a K- or Y-Gun.

Are you sure, that the have used the Thornycroft Mk.IV until the end of the war and haven´t upgraded to the Thornycroft Mk.V?

Thanks in Advance mate:salute::yeah:

Padi, small historical research for you:

1. There is only one source of information (one author and one book) about Thornycroft DCTs on board of Grom class just after building and shortly after WWII beginning, so it may not be true. Even then it's true amount of available DCs for DCTs shouldn't exceed 10 (max 20) DCs, similar to Wicher class (20 BH 200 for racks and 10 for throwers). IMHO better to legitimate that there were not any DCTs onboard of Grom class, up to ORP Błyskawica overhaul started on 20.06.1941.
2. The single DCTs on Wicher class were most likely removed from these destroyers in 1934. After that in 1940 only ORP Burza was equipped with two Thornycroft DCTs and in 1942 with four Mk.IV DCTs.
3. I've found nowhere info about Thornycroft Mk.V throwers onboard of ORP Błyskawica and ORP Burza, so only Mk.IV version is verified.

Don't forget important info:
ORP Wicher and ORP Burza were both Wicher class, built in France. ORP Burza survived WWII, but ORP Wicher was sunk by German planes on 3 September 1939.
ORP Grom and ORP Błyskawica were both Grom class, built in UK. ORP Błyskawica survived WWII (she's still on the waves as museum-ship in Gdynia, Poland), but ORP Grom was sunk by German planes on 4 May 1940.

You gave me very interesting job with this, I wanna buy fresh released monography of all Polish destroyers using during WWII for making comprehensive research for you :)

Thanks!
Nice that you have fun doing this😄
I have fun implementing your data😉

The polish ships are now working. I´m at the moment in the progress of testing and debugging.

Very good news :up:

I have uploaded the new v.3 Beta 4.

More infos in the first post.

The next step are the french and italian DCs, which are the Focal points of the next version. Informations to them are also welcome;)

After I have finished them I would add the last few ships which I left out until now.

What about Gwx? Is where mod similar?

The adaption for GWX is in the works.

YES The must have mod is getting updated to GWX

Good news, the Mod is again in development!
I have lost interest on SH3 because of some bad things happened in the Marinesims-Forum by one member, but after more than a half year without SH the interest is back again so I´m beginning to add the missing ship equipment.
But I think that I need help with some classes because I find very less information about french, italian and some other ASW-weapons.

I am glad to hear that you are keep on your good work on this mod :up:

I might have something for you on my HD: declassified documents on German, Italian and French ASW weapons, and a few British/American DC models (but if need be, with the time I could as well model other neation's ammonition and throwers) :03:

Sounds vers nice and helpful!
Also that you have models available is like a dream come true!
Do you also have information about the ammount of DC's the vessels have carried, because for some ships like the french or the Isaac Sweers I find zero information.
Thanks

Hi padi, and sorry for the late reply. I need to check the documents I have available as I didn't look at them in a long time. I think, but I am not sure, they have information about DC shapes, sizes, weights, type and quantity of explosive charges used, types of detonators used and detonation mechanisms, kill radii, etc.
Some good documents that you can start from are found at the following page:

http://www.lexpev.nl/manuals/unitedstates.html

Navweaps.com also has a good deal of data, but you probably know it already. Most of the information collected in it comes from John Campbell's Naval Weapons of World War Two, of which I have a copy. Should you need to check directly the source, I will be glad to do it for you.

Talking about 3D stuff, I have good quality models of the following depth charges: Type D MkIII, MkVII, MkVII-Heavy (GB), Mk6, Mk7, Mk9, Mk9-Mod2 (US). All the models are by me, so no need to ask for permission to use them, and they come with throwing arbor models as well :up:
