Hi I have for years possessed a copy of both ONI 225-J and ONI 41-42, which are Navy Intelligence Documents on Japanese Army Weapons and Air Force Weapons and Equipment: and Japanese Warships respectively. I've never had the opportunity to show these to anyone until now. So here are a few pages covering Japanese Army Weapons and Equipment from ONI 225-J. As the publication was prepared in 1943, the intelligence represents that gathered in places like the Philippines, Malaya, New Guinea and Guadalcanal. I hope the pages are of interest. Regards mgk

mgk1951,
It is interesting reading what the US thought of their enemies weapons capabilities. That list is more extensive than I imagined and I even see the knee mortar there.
I can understand them putting captured army weapons and air force planes through their paces to collect data but how would they get Navy ship information?
Knowing what you know today, how accurate was this 'intelligence'?

I really enjoy looking at these photos. Lots of information can be pulled out of them.
Thanks Dan

Hi fots2 and one50
I'll post a few more pages this week. There is an interesting summary of the Japanese landings in the Philippines. There is also some interesting information and photographs of aircraft and landing craft.
The Japanese warships document is full of photographs, plans and photographs of models. Models are photographed from different angles and elevations for use by pilots.
Some of the information on Japanese warships more than likely came from pre-war copies of "Jane's Fighting Ships". These volumes have been published since 1898, originally titled "Jane's All the World's Fighting Ships".
I'm glad these were of interest in this new Forum of Weapons and Materiel.
Regards
mgk

mgk1951,
Thanks for the information. I was aware of 'Jane's' books but I had no idea they have been published for so long.

Hi Additional pages pages from ONI 225 J - 1943 this time covering Notes on Landing Operations - Brigade Forces using Japanese landings at Lingayen Gulf as an example. This is the whole section on Japanese Aircraft. I'll add some pages from ONI 41-42 1942 covering two Japanese Warships soon. I've chosen two warships that were sunk inside Manila Bay. Regards mgk

Pages from ONI 41-42 covering HIJMS NachiONI 41-42 is arranged with 6 pages of photographs, drawings and models per ship class. Pages 2 and 3 appear to be designed to be used by navy aviators, as the ship models are photographed from various angled profiles; and 45 degree vertical angles. HIJMS Nachi was sunk on 5th November 1944, by aircraft of TG 38.3, approximately 12 Nautical Miles north-east of Corregidor. Aircraft from USS Ticonderoga (CV-14) and USS Lexington (CV-16) attacked in two waves, scoring multiple bomb and torpedo hits. The bow of Nachi was eventually severed from the hull and the ship sunk quickly after the aft magazine exploded. Regards mgk

Nice photos and illustrations. Some comments
The use of the the carrier was not in Lingayen but it was in support of the Legaspi and Davao landings. The only carrier the Japanese employed in the Philippines was the light carrier Ryujo.
During the Philippine operations in Lingayen (main landings) Japanese vessels there were: 2 light cruisers 16 destroyers a number of torpedo boats, sweepers and minelayers There were 63 light landing crafts, 73 large ones and 15 "extra large" ones with an additioanl compliment of 48 powered sampans.
It was not a brigade that landed in Lingayen but a Division, supported by regiments from other elements. Two Tank Regiment, (the 4th and 7th, landed as well), with two regiment and one battalion of field artillery.
Regardless if they got the figures or accuracy, the ONI 41-42 gave the Americans an indication of how and what the Japanese were up to.
Cheers,

Hi batteryboy
I agree that the information contained in ONI 225, although inaccurate was still an indication of Japanese tactics. Published in May 1943, but containing information gathered during the dark days of 1942. These were still desperate times and any information was useful.
Regards
