Wow! The American Heritage Museum (you may know them as the current holders of the last surviving Ho-Ro) have recently announced the restoration of a Type 97 Te-Ke.
Interesting still, they have determined this vehicle to be a rare gas scattering variant, although I am not sure if this is exactly what they plan to restore it to, but they did mention to be looking for an accompanying trailer.
Rare Japanese Type 97 Tankette “Te-Ke” Restoration Project Begins at American Heritage Museum - The American Heritage Museum
They intend to restore it to running condition with the original Ikegai 65hp diesel engine, and are requesting technical materials to assist in restoration, so I was wondering if there’s anything available to contribute.

This only refers to the modular turret cheek and UFP composite blocks. The composite behind the mantlet is not removable.

Ups I forgot about that, but I doubt the breach armour makes up the 1,260 kg that are missing? That sounds way too heavy.

It’s a wider piece individually compared to the cheek inserts, and at least said to offer equivalent protection.
Though this would also mean that the turret cheek inserts are only 680kg, or 340kg a piece. That is probably the hardest part for me to believe unless there is more fixed composite pieces, or some placeholder frame that adds to the weight even when the armor is removed.

You’re not missing anything. They reduced weight everywhere else they can. Doubled the armor in the key areas using more advanced armor as well.

Yea that seems like something is off, I wonder why Japan didn’t go with a smaller breach design like the 2A5 and others like the Abrams.

The general idea seems to be that instead of a small breech that minimizes the resulting weakpoint, they instead chose a larger and more armored breech to match the targeted armor preotection of the rest of the turret face.

It’s not and it checks out. The tank is way smaller, and they only stick composite where it needed to be stuck as to keep weight down unlike the Abram’s and leopard. Again, this tank was tested against its own round and the base armor withstood its round at a simulated distance of 250 meters
It is a smaller breach is the thing, the current modeling in game isn’t accurate at all as far as references go. Don’t look at the model in game it’s atrocious

If only Gaijin gave Type IV APFSDS to the early version of the TKX in game. Then we would have proper, Gaijin approved penetration values for the round that was most likely used in testing.
Though I guess they could still argue that it was only “200m with reduced charge”, with the 250m being only assumed from a separate test specification calling for 250m. Not sure if that is enough for Gaijin just yet.

It still is a larger breech than the Leopard or Abrams. Yes, the tank is smaller, but the breech is (not just proportionally) large.
Unlike the Abrams or Leopard, full composite protection is worked into the breech, and tested to the same specifications as the turret cheeks. This means that like the cheeks it has at least sufficient protection to stop Type IV APFSDS fired from a distance of 200m with a reuced charge to simulate a distance of likely (but not certain) 250m.

Review of the Type 10 and it’s capabilities
Introduction
It’s no secret that the Type 10 MBT is one of the most technologically advanced tanks introduced into warthunder. In update “winged lions” gaijin folded and introduced the Type 10 hitomaru MBT of the Japan self defense force. Fielding a 120MM main gun, 12.7 machine gun, 3rd gen thermals for both the gunner and commander, commander fire control system “hunter killer”, 4 second reload, and an adjustable suspension it was certain to be a force on the battlefield within warthunder. Unfortunately Gaijin has made fatal mistakes to the model, reload, suspension capabilities, the type 10 rounds penetration values, acceleration and more. In this article we will be taking a look at these fatal mistakes in depth with sources coming from

In game currently, the armor is labeled as 440 for the UFP, 565 for either turret cheek, and around 300 for the gun mantlet. None of these figures are accurate.
According to the “Mitsubishi heavy industries: New tank part 5”
Page 4 of the 88 page section
Turret armor has 3 sections
“it consists of a firearm section, a turret shell. a turet device section and a turret crotection section.”
On page 5 it goes into more detail
“and a) The turret shell body is a welded structure of bulletproof steel plates, special steel plates and general materials, and consists of each component surface as well as internal bulkheads
and turret module armor mounting parts.
b) Of the individual component surfaces, an opening and a gun trunnion bearing section will be provided in the center of thefront, allowing a 120mm tank gun to be installed.”
Here’s another phrase that points out the fact that the tank is missing armor as well
“Additional armor is provided on the top and sides of each component surface (see Annex
C) shall be constructed in such a way that space can be secured for installation.”
Page 6
“n) The turet module armor mount na section shall be constructed so that the turret moduli
armor can be incorporated into key parts.”
“The turet module armor mount na section shall be constructed so that the turret moduli
armor can be incorporated into key parts.”

We get a glimpse into the weight of the Type 10
We see that they in fact reduced the weight of the vehicle all around yet increased the weight of the armor
The protective performance of Type 10 is described in the specifications of it.
According to it, the Gun mantlet also has the capability to protect against 120mmKE
Describes additional armor.
The status of the additional armor is concealed by the armor cover.
Therefore, there is no difference in appearance due to changes in the level of protection.

The breach is still of significant size, double so relative to its size. The leopards specifically replaced the breach from the 2A4 → 2A5 with a much smaller one likely due to weight and armour concerns.

In the actual diagrams for the turret the breach isn’t as large. There’s like a mm’s worth of gap and it’s not as big.
Proportionally??? I have 0 clue and I honestly didn’t look into that. Maybe someone else here with documents can make light work of this and get something done
