Same here but sometimes I like taking potshots at sampans for gunnery practice.

;) I'll try and change it for you then !

OK. I posted the pics they are here. http://hosted.filefront.com/TakaoSH4/
Look in the I-19 folder. They are quite large, both in size and storage space. They are scanned at 600dpi, they first ones I did were at 1200dpi and were just too huge.
There are two scans of the same photo of I-14's conning tower, one I have tried to lighten up to get more detail, the original was just too dark. The next is of I-14 approaching I-400. Finally there are two line drawings of I-14, and one of I-9.

Sorry Keltos01, but the only picture I could find of I-9 was one taken from almost directly aft and is rather dark. There is reasonable detail of the aft hull, but the conning tower and forward section are lacking in detail.

Pics and drawing are taken from :
"Japanese Naval Vessels at the End of World War II" compiled by Shizuo Fukui
"Imperial Japanese Navy Submarines 1941-45" from Osprey Publishing
"Warships of the Imperial Japanese Navy, 1869-1945" by Hansgeorg Jentschura, Dieter Jung, and Peter Mickel.

if they come from a book, know that books are printed at max 400 dpi resolution, so 1200 dpi scan is a bit much :rotfl:

Yeah, I goofed the first time around. But to make up for it...I've found PLANS to I-14.
Now there is no scale for the plans just go by frame number. But, they are there: Top view, side view, and cross sectionals

I've uploaded them to my filefront page in folder USNTMJ or go to the webpage:
http://www.fischer-tropsch.org/primary_documents/gvt_reports/USNAVY/USNTMJ%20Reports/USNTMJ_toc.htm
Ok the link still directs to the main page for the Fischer Tropsch Archive. The work around is this, just do a copy of the web address and paste it in the address bar of your web browser. Or goto the main page. Under the Primary Documents, click on Government Reports. From that page, click on U.S. Naval Technical Mission to Japan.

scroll down to SERIES S: SHIP AND RELATED TARGETS JM-200-G and do a "Save as" on
S-01-7 Charateristics of Japanese Naval Vessels- Article 7, Submarines

The plans can be found beginning on pg 45 of the document. There is also a grainy pic taken from the bow looking aft towards the island on pg 49.

It all began because every source I have mentions that the I-14 had a deck gun, but in the pictures I scanned, there is no sign of one. So I went back to the Fischer-Tropsch Archive website and started looking through the US Technical Mission to Japan documents to confirm the lack of a deck gun on I-14. Not only did I find confirmation that no deck gun was on I-14 when the Americans took it over, but I found the Deck Plans too!

Now the question is was a gun fitted and then removed or was one never mounted on I-14, but fitted to other submarines of the class?

Interesting....

*NOTE* I listed the parent site for the U.S. Naval Technical Mission to Japan. I have changed it to the direct link to their documents. Sorry for the error. Stupid frames.

late war
 
subs had their deck gun removed so that they could mount kaitens on deck.
k

ps how did you find that site??? really interresting !:up:

Takao 06-13-08 09:07 AM

It was one of those sites that I stumble across while searching for information. Been bookmarked for some time now. I've cited it several times in this forum and others. Although I had forgotten all the information they had on the I-14, I used it in response to questions on the I-400.

I know that some Japanese subs had their guns removed to carry kaiten, but I have never heard of I-14 being converted or modified as a kaiten carrier. Maybe it was done as a space & weight reduction measure when the internal torpedo storage was reduced to carry extra aviation fuel and torpedoes for the I-14's aircraft. Mention has been made of bulges being fitted to increase reserve bouyancy and maintain freeboard. I think this is the most likely reason for the gun's removal.

I've tried to edit the link in my previous post, but it still directs to the main page. Please follow the intructions in red for a lot of other good reports about the Japanese Navy. Let me know if there are any problems.

200 Downloads !
 
We crossed the 200 download mark for this mod :D
Thanks to all !!
Keltos

Ps I'm gonna work on the japanese subs soon, as soon as I figure out the 11th tubes or more, we'll need those for the C2 Class which has 2 aft and 6 forward since the german torpedo pannel allows only 6 tubes :down:

moreover the animations need to be added for the torpedo doors on the bow... still can't get around that part yet:damn:

back on
 
Well, as they only have 6 tubes forward, this one should be easier, also I didn't want to mod the Sen Toku for now, cause for one Peabody's way ahead of me, even if it's a US sub (if you ever wanna get rid of those pontoons/stairs sailing with your boat just tell me where to download it and I'll remove them for you Peabody) so I started the next big thing : the new I 14 class, which has a short Sen Toku type tower with place for only two planes, a shorter hull (I scaled down the stock Sen Toku hull) and only six forward tubes.

here's the WIP :

black tower
 
alright, I posted the current version 1.0 of the mod on my filrefront page, the tower is still black and it has a lot of issues yet to be resolved, the hull is fine though ?

If anyone care to have a look, I'd appreciate it :up:

If you look in one of the above posts I made you'll see what the tower looks like in 3DS, where, as always, it looks fine :damn::damn::damn: why is it so damn hard to get things in game???

back to 3ds, I'll try and export the uv map on channel 2, I think I did that last time I got a black stuff.

here's what it look like in 3ds :

Thats one good looking sub :)

Xantrokoles 07-01-08 04:47 AM

Why have you splitted the working model?
You can add the periscope and the watchcre and bla bla to you submarine.dat too.
When you have looked at for example Mikhayl's Clemson, you could see, that you don't need the unitparts.

keltos01 07-01-08 04:49 AM

ears
 
as you probably know the japanese didn't have a real radar on subs during WWII, instead they relied on "ears" to spot approaching airplanes, with the success one knows :dead:

I saw in one of my latest (1979) IJN sub book that the Kaidai and the Jyunsen b were fitted with those. I decided to do the same (maybe for a late war tower?)

I also added the horn stuff (isn't that a schnorkel ?)

there it goes :

I modified the tower Xantro, so I had to keep the hull intact and split the tower, but maybe you're right : I could keep the tower, get rid of the 3d model inside, add the 3d model of the tower to that of the sub, and voilą a complete sub ???

I never tried without a tower, that's why, well as the I 14 never changed tower, you're probably right. The result will have to wait till tomorrow though, I'm not home tonight.

a question concerning the unitparts : does the number unitsparts8triton have to be the next after that of the last ship/sub unitspart ? or can we put anything ?

posted the .obj and dds of the tower here :

tower AM
 
I had to flip a few faces in 3ds but it's done at last ! I also made an occlusion map for it, it took ages ! then I realized I had not one but 3 clones of my tower stacked on top of each other:oops:

if you look closely at the picture you(ll notice some elements are missing, their faces are flipped, the black face showing.

http://img185.imageshack.us/img185/1606/tower5xc8.jpg

I also made the submarine class image, taken from the section of the sub found at Fisher-thorpe :
