The problem is that the only information we have is “ATLA purchased 30mm proxy fuse round”
There is no any information, even approximately what performance it has so chance that it will be added in game is low

I wrote a bug report for the So-Ki if you’d like to support it

So-Ki Has the Wrong Guns // Gaijin.net // Issues

Thank you for submitting the bug report. I would like to provide an additional source that might be helpful.

Following the example of the 20 mm Type 4 twin-barrel AA machine cannon on the Ha-Go Fighting Boat Model 1, I believe the name of the gun in the game should be “20 mm Type 98 cannon at So-Ki II mount.”

A document from 1942 states that the 20 mm So-Ki II cannon was mounted on the Type 98 Ke-Ni, and the elevation angle of the 20 mm So-Ki I cannon is from -10° to +90°.

I believe the name of the gun in the game should be “20 mm Type 98 cannon at So-Ki II mount.”

Are the guns on the So-Ki not supposed to be the Type 2 20 mm guns? This page does mention the So-Ki II mount, but JP Wiki also says it’s the Type 2 guns, not Type 98.

Also this website says -15 to +95, is this wrong?

The 20 mm twin-barrel So-Ki AA machine cannon is a modification of the 20 mm Type 2 Ke-Ki AA machine cannon into a twin-barrel mount. The codename “So-Ki” is believed to be an abbreviation of “twin-barrel” (双連 Souren) and “machine cannon” (機関砲 Kikan ho). I believe that the elevation angle of the single-barrel 20 mm Type 2 Ke-Ki AA cannon is from -15° to +95°, but I am not sure if the So-Ki cannon, which was modified to have twin barrels, has the same elevation angle specification.

According to the testimony of Major General Giichi Dōgane, who designed the 20 mm Type 98 AA machine cannon and the 20 mm Type 2 Ke-Ki AA machine cannon, as well as the armament for the SPAAGs Ta-Se, So-Ki, and Ta-Ha, the 20 mm twin-barrel So-Ki AA cannon was mounted on the Type 98 Ke-Ni.

Okay, I will propose the name be changed to “20 mm So-Ki Type II”. Is this more correct?

As for the elevation, considering that we do not know the specific angles of the twin So-Ki, I think it’s safe to bet that it is similar to the Ke-Ki, from which it is derived.

I launched the War Thunder client and looked at the stat card. I realized that the notation “20 mm So-Ki Type II cannon x 2” might imply a quadruple-mounted cannon, so I thought it would be better to use “20 mm Type 2 cannon x 2” instead. I apologize for the confusion.

I will provide the source of the photo and diagram showing the elevation angle of the 20 mm Type 2 Ke-Ki AA cannon, which ranges from -15° to +95°.

I don’t know where this one gets “Type 4”. No stats in any pages. At least the photo is relatively good quality.

Just wanted to share there was an update to the dev server after it closed that gave the Type 16’s, Type 10’s, and the CTWV (P) driver thermals.

If you see the new comment I made, I went with “20 mm So-Ki Type II”, as this was specifically developed for usage as a dual-mount AA on the Ke-Ni. But if Gaijin insists on having the “x2” notation, we could have “20 mm Type 2 Ke-Ki x2”, or “20 mm Type 2 x2”. Latter is more suitable in terms of consistency regarding other SPAA, in my opinion.

I think the photo in the report is of the 20 mm twin-mounted So-Ki model I AA cannon.

This is the 20 mm twin-mounted Type 4 So-Ki model IV AA cannon. This pintle mount allows for quick control of elevation using the gunner’s shoulder and waist bands instead of a crank handle. It was developed to shoot down F6Fs and other aircraft that perform low-altitude strafing runs. I believe the basic performance of this cannon, such as muzzle velocity, rate of fire, and sight, is the same as the Type 98 AA cannon. This anti-aircraft gun was supposed to be mounted on the Ho-RI II.

Are there other documents which list Chi-Ha’s top armors? I haven’t seen one about Chi-Ha Kai.
