Something interesting about Merkava III's armor protection(in Chinese):
Some of these images are come from Chinese course book《装甲防护技术基础》（The basic technology of armor protection）, and others are come from this issue： http://www.cnki.com.cn/Article/CJFDTotal-BQZS200108004.htm
The main author of these two sources is one of the chief tank designers in China. Mr.Zhang has presided over a design of front-engine tank scheme under the frame of Chinese 3rd gen MBT, but there was little info refer to these history)

Special armor covered, those colored parts most likely are heavy NERA or Built-in-ERA structure modules, while others are lighter module I guess.

T-3/4 module before shooting by a HEAT warhead of HOT missile. According to previous picture, it should be the side armor of the turret. So we can assume that the front arc of Merkava III's turret, looks likely ±30°，which can withstand more than 700mm even 800mm penetration from CE threat.

Still the T-3/4 module,before hitting by a RPG warhead. 
I am confused this number as T-9/4 at my first look, but it is more likely a distorted "3". There are some reasons: (1) Its thickness doesn't seem to fit on top of the turret. (2) In this pic the threat is RPG warhead, moreover, its incidence normal angle is smaller than the previous HOT warhead, which can be used as a useful basis for judging.

The solid line is base steel armor's equivalent thickness, including spaced armor array inside the hull( The table above shows the thickness and inclination of the base steel armor,  unfortunately many  notes are missing in the PDF) and the dotted line is the special armor's protection capability against KE ammunition, up to 450mm RHA on turret front and 350-400mm on the UFP.

Going through the stuff I pulled out of my father's house, I found a document on X1100 transmissions.  It's basically a paper copy of a powerpoint so it's a bit light on info, but I have scanned a few pages that had interesting data. There is a lot more, let me know if you want more scans of details.
 



 

 

Share some less-known information about cold war period tracked vehicle transmission
 


Mithubishi transmission MT75 for STB, later known as Type 74.
The basic layout of MT75 is similar to the CD-500 transmission on M41 light tank, used by JGSDF in a short period after war.
But the Japanese tank designers prefer mechanical gearbox rather than hydramatic gearbox, they use a electro-mechanic high-low range instead of a torque converter. The high-low range part is described as "１次変速"(range first stage).
The steering mechanism is a single-radius, double differential type, operated by engaging steering clutch, also resemble the CD-500. 
 
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
 


 
Allison X-700 transmission, a 800-hp class transmission to replace XTG-411 on T95 medium tank in 1960s. 
Trials were successful but finally never adopted. The Army decided to develop a 1500-hp class transmission for XM803. 
X-700 then evolved into X-1100 transmission. The X-200 and X-300 were basically smaller variants of X-700. 
X-1100 users: M1 and its variants; Korean K9 "Thunder"; Turkish T-155 "Firtina"
X-300 users: Warrior IFV; CV90 series
X-200 users: M113 upgrade (A2 standard)
 
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
 


Allison XHM-1500-B2, a hydrostatic-mechanical transmission developed in early 1970s. A competitor against X-1100 but less successful. 
Different parts were shown in different color. 
Orange: power input and forward-reverse shifting mechanism;
Blue: hydrostatic-mechanical speed range (mechanical planetary gears were not shown in cutaway);
Red: hydrostatic differential steering system; 
Green: output shaft and planetary gears. 
 
 
Hope you enjoy these pics. 

From the article "Antiarmor - what you don't know could kill you" by US Army Reserve Major Michael R. Jacobson. There are some errors in the data (M60A1 protection level, muzzle velocity of the M829A1 APFSDS, etc.), but it seems overall to be quite interesting.
 
 
Probably spaced in front of the reference plate. Normal NERA achieves an even higher "thickness efficiency" if you include the empty space...

and help from Mr.Taki.

This is an article simply to show you guys here how Waffentrager is a faker. The original article  ( https://www.weibo.com/ttarticle/p/show?id=2309404213101531682050) was written in Chinese and Japanese. For better understanding I will translate and edit the article and post it here. 
  And I must tell you why I want to reveal this shit: Long time ago I found many sayings from Waffentrager’s blog which I had never heard of, so I turned to my Japanese friend and IJA tank researcher Mr.Taki and asked him to confirm a few of them. In the end it turned out that none of Waffentrager’s article is true. I once argued with him and he not only failed to give out his reference but also deleted my replies! I’m very angry!
 
  Now let’s get started.
 
  At the very beginning I recommend all of you who opened this post to take a look at Waffentrager’s original article, that will help you understand what I’m debating.
 
  Here is the link to the original article: https://sensha-manual.blogspot.jp/2017/09/the-ho-ri-tank-destroyer.html?m=0  
 
  In China we need to use VPN(aka “ladder-梯子” or “the scientific way of browsing the Internet-科学上网” in Chinese)to open that link above so at first I post out Waffentrager’s original post in the form of screenshots in my article. I’ll skip that here.
 

 
Fig.1: I will skip his original article.
 
  Now, I had raised my first question here: Please take a look at the screenshot:
 

 
Fig.2: My first question
 
  In the original article, Waffentrager insisted that the Type 5 gun tank was built in July, 1944 and fully assembled in August. It was also put into trials at the same time.
 

 
Fig.3: Waffentrager’s original article.
 
  But, is that true? Let’s have a look at the Japanese archive:
 

 
Important Fig.4: Archive code C14011075200, Item 4
 
  Notice the part with the red, this is the research and develop plan for the Japanese Tech Research center in 1943, and had been edited in 1944. ◎砲１００(Gun-100) is the project name for the 105mm gun used by Type 5 gun tank. The column under it says: “Research a tank gun with 105mm caliber and a muzzle velocity of 900m/s”. This means that the gun had just begun to be developed and from the bottom column we can know that it was PLANNED to be finished in 1945-3[完成豫定 means ”plan to be finished” and 昭２０、３ means ”Shouwa 20-3”. Shouwa 20 is 1945 in Japan (you can wiki the way for Japanese to count years I’m not going to explain it here)]
  Next let’s move on to the Type 5 gun tank itself, here is the Japanese archive:
 

 
Important Fig.5: Archive code C14011075200, Item 7
 
  “新砲戦車(甲)ホリ車” is the very very first name of Type 5 gun tank, it should be translated into:”New gun tank(A), Ho-Ri vehicle”. “ホリ” is the secret name of it. Still from the column we can easily know that Ho-Ri was also planned to be finished in 1945-3. But under that column there is another one called:”摘要(Summary or outline)”, in this it says:”砲１００、第一次試作完了昭和１９、８”, In English it is: “Gun-100, First experimental construction(prototype construction) finished in Shouwa 19-8(1944-8)” What does it mean? It means that in 1944-8, Only the 105mm gun used by the Type 5 gun tank was finished! If the Ho-Ri tank itself was finished why it was not in the 摘要 column? So how could an unfinished tank mounted the prototype gun? Waffentrager is talking bullshit.
Also from Mr.Kunimoto’s book, he gave the complete schedule of the 105mm gun, here it is:
 

 
Important Fig.6: Kunimoto’s schedule
 
  “修正機能試験” means ”Mechanical correctional test”, it took place in 1944-8, this matches the original Japanese archive(though this chart was also made from original archives). At that time the gun had just finished, not the tank.
 
  Next is this paragraph from Waffentrager’s article:
 

 
Fig.7: Weighing 35 tons
 
  From the archive above(important Fig.5) we can learn from the second large column”研究要項(Research items)” that Ho-Ri was only PLANNED to be 35 tons, and maximum armour thickness was PLANNED to be 120mm, not was. Waffentrager is lying, he used the PLANNED data as the BUILT data. I will post out the correct data below later to see what Ho-Ri is really like when its design was finished.
 

 
Fig.8: 全備重量-約三五屯(Combat weight-app.35t), 装甲(最厚部)-約一二〇粍(Armour, thickest part-app.120mm)
 
  At this time, some of the people might inquire me that:”Maybe the Type 5 gun tanks were really finished! You just don’t know!” Well, I will use the archives and books to tell these guys that they are totally wrong. None of the Type 5 gun tank was finished.
  Always let’s look at Waffentrager’s article first. He said that a total of 5 Ho-Ri were completed.
 

 
Fig.9: Waffentrager said 5 Ho-Ri were completed.
 
 He also put an original Japanese archive(C13120839500) to “enhance” his “facts”.
 

 
Fig.10: Waffentrager’s archive
 
  Everyone can see the”ホリ車,1-3-1” in the document, and someone might actually believe that 5 Ho-Ri were actually built. But they are wrong! Waffentrager is cheating you with “only a part of the original document”! Here is what the original archive really looks like:
 

 
Important Fig.11: Archive code C13120839500, Item 7
 
  “整備計画” is “Maintenance plan” in English, again it was PLAN! The whole plan was made in 1944-12-26. I don’t actually know how Waffentrager can misunderstand this, maybe he doesn’t even know Japanese or Chinese!
 

 
Important Fig.12: The cover of the same archive, “昭和十九年十二月二十六日” is 1944-12-26” in English.
 
I have other archives to prove that Ho-Ri were not finished as well:
 


 
Important Fig. 13 and 14: Mitsubishi’s tank production chart made by the American survey team after the war ends.
 
  From the chart you can only find out Type 4 and Type 5 medium tanks’ record. There is no existence of Type 5 gun tank Ho-Ri, or the”M-5 Gun Tank” in the chart’s way.
 
  Except for the archives, many books written by Japanese also mentioned that Type 5 gun tank were not finished:
 

 
Fig.15: Kunimoto’s record.
 
  “二〇年五月完成予定の五両の終戦時の工程進捗度は、やっと五〇パーセントであり、完成車両出せずに終戦となった。” In English it’s: “When the war ended, the five Ho-Ri planned to be finished in 1945-5 had finally reached 50% completion. No completed vehicle were made when the war ended.”
 
  Here is another book written by Japanese with the help of former IJA tank designer, Tomio Hara:
 

 
Important Fig.16: Tomio Hara’s book
 
“完成をみるには至らなかった” Again he emphasized that the tank was not finished. Also when Ho-Ri’s design was finished its combat weight was raised to 40 tons, not the planned 35 tons. It was only powered by one “Modified BMW watercooled V12 gasoline engine”, rated 550hp/1500rpm. In Waffentrager’s article he said later a Kawasaki 1100hp engine were installed, but obviously that’s none sense. There was really existed a Kawasaki 1100hp engine but that is the two BMW V12 engine(Same engine on Type 5 gun tank or Type 5 medium tank) combined together for Japanese super-heavy tank O-I use. It will take much more room which Ho-Ri do not have.
 

 
Fig.17: O-I’s engine compartment arrangement. There’s no such room in Ho-Ri for this engine set.
 
  And last here are the other questions I asked
 

 
Fig.18: Other questions I asked
 
  I have already talked about the questions regarding C13120839500 and the engine. As for the gun with 1005m/s muzzle velocity, the Japanese never planned to make the 105mm gun achieve such a high velocity because they don’t have the enough tech back then. Also from the archive C14011075200(important fig.4) the 105mm gun was designed only to reach about 900m/s.
 
  So, after all these, how did Waffentrager replied? I will post out the replies from my E-mail(because he deleted my replies on his blog).
 

 
Fig.19: Waffentrager’s first reply
 
He kept saying that my archive is not the same as his and he is using his own documents. I didn’t believe in these shit and I replied:
 

 
Fig.20: My reply
 
  Last sentence, the Ho-Ri III he was talking about is fake. There are only Ho-Ri I(The one resembles the Ferdinand tank destroyer) and Ho-Ri II(The another one resembles the Jagdtiger tank destroyer). He even photoshoped a picture:
 

 
Fig.21: Waffentrager’s fake Ho-Ri III
 

 
Fig.22: The real Ho-Ri I and the base picture of Waffentrager’s photoshoped Ho-Ri III in Tomio Hara’s book. Many same details can be seen in Waffentrager's fake Ho-Ri III
 
  The 4 variants of up-armoured Type 3 Chi-Nu medium tank is also fake, I will post his original article and the confirmed facts I got from Mr.Taki by E-mail.
 

 
Fig.23: 4 models of up-armoured Chi-Nu by Waffentrager
 

 
Fig.24: Mr.Taki’s reply
 
  Waffentrager used every excuses he could get to refuse giving out the references, and finally he deleted my comments. What an asshole!
 

 
Fig.25: Our last “conversation”
 

 
Fig.26 He deleted my comment.
 
  So, as you can see, Waffentrager is really a dick. He is cheating everybody because he think that we can’t read Japanese. Anyway I still hope he could release his reference and documents to prove me wrong. After all, I’m not here to scold or argue with somebody, but to learn new things. Also if you guys have any questions about WWII(IJA) Japanese tanks, feel free to ask me, I’m happy to help.

Considering it turned out WaifuTrucker is a lying dick, I'm not trusting this one. Especially since it has some of that "oooh look at me typing text and blacking it out im so secret" stuff.

Talk about Type90, i got some information from Chinese document which mention about the armor composite used on Type88 which is the prototype for Type90 recently. Not sure the exact truth but i would like to share.

“Japanese Type88 tank's turret and hull composite armor were trying to use different ceramic material (Alumina、Silicon oxide or Silicon carbide ceramic cut in rectangle or hexagon),each layer using binder to bonded together. The protection of this armor can reach up equal to 400mm thick of armour steel (BK) and is capable of defeat 120mm high density KE projectile (muzzle velocity>1600m/s) fired from 200meters at 0 degree, and also capable to protect against the 120mm HEAT shell which capable of penetrating 600mm of armor.  Besides, there are many of different type of armor plate, the use of ceramic material and it's ability of protection giving the armor research development a new direction”
 

image10  Type88 tank's spaced (composite) armor structure.
陶瓷板=Ceramic plate    毫米=mm
 
Other than this，japan seems are developing some kind of Kevlar composite

It says:"Japan is currently develop a Kevlar fiber with Titanium alloy or aluminum structured multi-layer composite armor "
 
Of course those are just for the prototype of type90, but we can try guessing the armor from this

Guys, it's not over yet. 

And yes, I do have the original file, but for some obvious reasons I add some watermarks. 
 
Waffentrager is doing the same thing as he did on Warthunder forum. 
He is just bluffing with unknown source screenshots or photoshopped fake “documents”.
He deleted every post arguing the pictures' authenticity to make himself “invulnurable”. 

You are unlucky - in Wroclaw city where I live there is big LG corp factory whit many Korean Managers. And preatty close there is TAKATA and Toyota big factories.
Funny I know people who know both - Korean and Japaneese language. And I had ask them about this whit kindly ask for translate.
It cost me a lunch. 
 
And it's not about tank but indeed lenses. 
 
You are fucked in the ass misarable piece of shit who misinforms peoples here. Honestly - go to fuck yourself, and as many as it's possible dicks in to ass of you, your family and dog or other pet you have.
GTFO!!!
 
 
 
 
 
 

Considering this was posted by someone new, I had it checked with a translator I know. And yes, this is about cameras, not tanks.
 
Also you can say bullshit and fuck on this forum, welcome to the club.

Waffentrager YOU FAKE BULLSXXT and FXXK OFF

In case you guys here cannot read Japanese:
It says "Height of lens assembly is about 380 mm"
May be taken from a manual of digital camera or sth. else. 
 
 

So basically Damian is having a meltdown.
 
What a shock.

It's interesting.
