Description

The Type 97 Chi-Ha Short Gun is a premium rank II Japanese medium tank with a battle rating of 2.0 (AB) and 1.7 (RB/SB). It was introduced in Update 1.65 "Way of the Samurai" with the initial Japanese tank tree.

The Chi-Ha Short Gun is a Naval refit of the Chi-Ha Kai with a Navy short gun (120 mm), it keeps the decent mobility from the Chi-Ha chassis but loses the turret rotation speed due the added weight of the gun.

General info

The Type 97 Chi-Ha is an upgraded version of the earlier Type 89 I-Go Ko. The engine has been upgraded, from the Mitsubishi A6120VD air-cooled straight-six diesel with 120 hp to a Mitsubishi SA12200VD air-cooled V12 diesel with 170 hp. As such, the top speed has increased from 27 km/h on the I-Go Ko to 40 km/h on the Chi-Ha.

The Chi-Ha Short Gun is a later iteration of the Chi-Ha with a modified turret coming from the Chi-Ha Kai. For firepower the Chi-Ha Short Gun has a Navy short gun (120 mm) that launches 13 kg HE shells.

Which was made to support navy infantry as a gun tank during the defense of the homeland.

Armaments

Main armament

Chi-Ha Short Gun firing

The gun from the Chi-Ha Short Gun is naval short gun built to deal with submarines and close range naval combat, and that does translate over in-game as a gun with lackluster HE filler just enough to destroy light tanks and a very low muzzle velocity, which on the bright side can be used to shoot at vehicles over cover.

Usage in battles

Chi-Ha Short Gun coming out behind a rock

Because the Chi-Ha Short Gun was designed for an infantry support role, its performance shows how tank combat wasn't put in mind for the vehicle. With each shell only having 2.5 kg of explosive, this isn't enough to destroy any vehicle the shell hits; it most likely will shock the crew, but nothing else.

Most light armored vehicles and tanks (<30 mm armor) will be able to be destroyed from either hull break or crew knock-out wherever you hit. But when you start opposing medium to heavy tanks, you should fallback for friendlies to deal with the target. It might be possible to hit the roof of the turret or hull on these vehicles, but it's a tricky shot and won't always deal a fatal blow on first hit.

History

Development

The Chi-Ha Short Gun, designated the Short Barrel 12 cm Gun Tank (短十二糎自走砲,Tan Jū ni Senchi Jisōhō) was a navy refit of the Type 97 Chi-Ha Kai to make a similar gun tank as the Army's Type 2 Ho-I Gun Tank with greater firepower to support Special Naval Landing Forces (SNLF).

To get greater firepower than the Type 2 Ho-I, a naval short barrel 120 mm was chosen with an additional bespoke muzzle break, the official designation of this 120 mm gun is unclear but may greatly be the 12cm/12 short naval gun. Additionally, there was a small storage compartment added onto the back of the ShinHoTo Chi-Ha turret.

Combat usage

The only certain information on this variant of the Chi-Ha is that only a dozen or so vehicles have been built of this variant and all have been deployed with the Yokosuka No.16 Land Battle Squadron. The Chi-Ha's weren't the only vehicles assigned to this Squadron and saw service next to the Type 2 Ka-Mi and Type 3 Ka-Chi amphibious tanks.

These vehicles would most likely would have seen service in defense of the homeland next to the Special Naval Landing Forces (SNLF) infantry. But in-case these Gun tanks would push forward these would most likely be transport by Daihatsu-class Landing Craft's just like the infantry accompanied by the Amphibious tanks

There's only a handful of images of Chi-Ha 120 mm's, all being American and taken at the naval yard in Sasebo, Japan, October 1945. None of the vehicles survive today.
