Thank you very much for the maps, it is appreciated. It is hard to find info on traffic for the US on the net (at least I had a hard time with it) I find were they were but not how they got there.

Kaidai 3a tower



http://www.worldweapons.eu/1-Warship...pan_ss-i55.htm







in S3D :





not perfect (yet) but it shows the 2 levels of windows that tower had. someone mentionned my KD3B tower to be too much like the KD6.woops this is a Kaidai 3a tower !!! now we need a hull with 8 fore tubes like the C2 type, this was the main reason I didn't build this sub at first : we were lacking the 8 tubes which we now have !

3b tower is the same, more rounded prow and no second windows row.


and then we notice they only had 6000 miles range at 16 knots (10000 at 10 knots, good enough !)... too short for our goals ?

My Grandfather was a USN convoy commodore for convoys between the West US Coast and Peal and other points. There were indeed escorts, DD usually with a light Cruiser sometimes for Convoy commodore or he chose the fastest merchie or a DD squadrom flagship as his flag. I have some of his war diaries and logs, but they are in San Diego and I am in Colorado buried under too much snow. Convoy protocol was similar to usual practice on other oceans, and in the Atlantic, comvoys formed up and set signals and formation practices at captains conferences on outset, convoy escorts had their own command structure but worked closely under the orders of the Convoy commodore. Much of the day to day and overall routine was top secret, and my grandfather did encounter Japanese subs which did make attacks but none were successful on his runs. All of this was kept secret even after the war and then was quickly obselete in the concerns for the Cold War new sub doctrine and so much of the actual history was lost or is buried in archives that are pre computer and becomeing more and more inacessible

Part of my problem is tho my Grandfather took copious notes and even had several articles published in popular magazines ....his writiing is so bad, such a terrible chicken scrawl that we can really not read much of what he wrote. I wish i could be of more help, but much of his logs were in code as well, his own, and shorthand for the events of the convoys.... routine but highly complex trying to get 50 or 60 ships zig zagging at high speed across the ocean coordinated with escorts and air partrols across the width of the Pacific. Not an easy job at all.

Thanks Admiral, you always have the info, and a story to go along with it. Too bad you can't read the logs, I bet they would be really interesting.

New site with IJN submarines data :

http://www.worldweapons.eu/1-Warship...lass_japan.htm

Keltos these IJN subs are getting better and better, great work! I wish i could come thru with some more info on them for you have stcuk out so far digging with the sources i have.... will keep hoping you can turn things up that you need. Amazing so little is easy to get about the IJN, after the war they had a ton of material and then i guess it either got shelved and lost now that we are digital in most archives or just tossed or taken back by the Japanese..i suspect they have a lot of stuff that they dont share. But dont know for sure.

i will keep trying.

[keltos01]

My understanding is that we now have quite a large amount of items in our mod such as :

submarine classes
submarine torpedo types
AA guns
Deck Gun Types
Radars
Hydrophones

the number of which can be confusing for the IJN beginner player.

So I decided to gather most of the data I collected on IJN subs and weapons and put it into one document available to all. Sources for the documents, chan available, are mentionned.

though not fully complete now this document covers the bold items of the above list.

included in it are the credits for the people who helped us, I sure hope that I didn't ommit anyone but if that were the case, please pm me and I'll revise the version.

Admiral Von Gerlach has sent me tons of links and info on the Japanese.

Hard to believe that most traffic was unescorted, esp given what happened on east coast of US in 1942 with German U Boats.Even if it bends history a little, makes for a much more interesting game when some of the singles have an escort of some type.Esp important ships like tankers or large freighters.





[quote=Shinbou Hakugei;1226480]By the way - I have question about US merchant shipping at Pacific. I cannot find sources about US convoy system at Pacific. It seems, all merchant traffic between West Coast and Hawaii, between Panama and Fiji, between Fiji and Australia, etc was absolutely unprotected. Only traffic between main bases and battle areas, made by NAVY freighters (AKA, AE, AO ships, etc), was protected by destroyer escorts.

Here is a pre-war maps, which will help (I hope) to create merchant traffic layers for Japanese campaign.

Hello everybody!

I'm a Hungarian subsim-fanatic. Now I play with SH3 and SH4 with U-boat Missions ext. pack. I should be glad to sail under the Japanese flag too. How can I do that? What have I do?
Is there a patch or an extension pack you made? And if yes: installing it makes the present saves useless as the previous patches did?

Welcome Wolfpack721, unfortunately the Japanese Campaign is not finished. And your saves will not work with it when we get it done.

Thanx for your swift answer, Peabody.
So I will have to restart the American and German campaigns again. But it will worth...
I hope the campaign will be ready in a short time. When will it be completed in your plans?

It should have been done long ago, but real life hit me right smack between the eyes. I just had to change priorities. So it is being worked on, I am afraid the first release will be very much Beta. Everything should work fine, but it won't have a lot of things I had planned.
The big difference from the 'stock' game will be more contact with Warships. The Japanese believed the way to win the war was to attack our Pacific Fleet not out supply ships and that is what we decided to do. Even though the Japanese didn't have much success, we hope you will when it is done.
There will also be shelling of the beaches before the US invasions, so a lot of action.
