For what it's worth to you.

From December 18 to 24, 1941, nine Japanese submarines along the U.S. west coast attacked eight American merchants sinking two and damaging two . It was the only time that more than one Japanese submarine patrolled the American coast.

On December 10, the 12 subs placed around Pearl Harbor were informed that an American carrier was heading for the U.S. mainland. Nine subs were ordered to pursue and sink it then take up positions at designated sites and attack American merchant ships. On Christmas Eve the subs were ordered to shell selected U.S. cities and lighthouses. After expending all of their 5.5-inch shells, they were to retire to Kwajalein in the Marshall Islands.

I also have read that as the war progressed, Japanese subs were hindered by the US breaking of their naval codes and a bad habit of shelling the enemy coast at the end of their patrol so they could claim having fired upon enemy soil. These two details allowed the US to intercept the subs on their return course.

I wonder how much havoc the IJN could have caused with the Allied supply lines in the Pacific if they had allowed their subs to launch a dedicated anti-merchant campaign.

it would have been devastating...

they had the best torpedoes and subs with up to 8 fore tubes..

(un)fortunately they never really sank merchants but for the Indian Ocean where they had their share of successes.

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.

Are the limber holes on the I-52 correct? I would expect them to be more like the Junsen B class.

Nice project keltos! (and spellbinding thread )

海軍未公開部分 - "Unpublished portion of the Navy" - (this google translate firefox extension really works! ;-)

Anyway, I recognize these and the youtube clip from a documentary I saw that described them as from a wartime Japanese propaganda movie. The documentary went on to say that this film was showing the spacious interiors of the mini-subs, the Japanese film version (using models) of the Pearl Harbor attack, and submarine duty, when in reality of course the interiors were much more compact.

Hi!

We are now at version 3.7 released, and version IJN Jyunsen B mod v 3.9.6 (non released) for the testers.

Just a quick note to let you know that all of our subs (14 of them) are now playable in campaign and single missions. We are still debating whether or not to include the Ko Hyoteki, this unit would then only be available for single missions (Pearl Harbor, Diego Suarez, Guadalcanal ..)

In mod subs are :

A1
AM
C3
JB
JB2
JB3
C2
J1M
Kaichu (not to be in the campaign)
Kaidai 3a
Kaidai 3b
Kaidai 4
Sen Taka
Sen Toku (WIP)

Keltos, do you have plan to include Kaichu 6 to the campaign?
I think it will be very interesting

not for now, we are polishing up the existing subs, and it had a short range didn't it ? 5000 miles at 16 knots.

Yes you are right. But it were the best medium displacement boats of the Imperial Japanese Navy and they had very rich military life. I think it would be very interestingly for the campaign.

PS. Kaichu 5 (RO-33, RO-34) had 8000 miles at 12 knots and Kaichu 6 (RO-35 and following) had 5000 miles at 16 knots

Searching......

I hate comcast, they have almost everything "on demand" on channel #1 here where I live and after digging there - no results so far.

Wow, the internet is full of bad misleading information.... so is TV. Reading some of these boards reminds me of that person giving history lessons on "another" forum when SH4 first came out until they were busted by someone who knew the facts.

Searching......
I'm thinking it was "UNSOLVED HISTORY" "Myths of Pearl Harbor" narrated by a female.

Must be produced by ABC?
http://abcnews.go.com/Technology/story?id=97715&page=1

UNSOLVED HISTORY of the MIDGET SUBS OF PEARL HARBOR.

Searching MILCH to see when its on in the near future:
