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

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.

Pros and cons

Pros:

• Familiar Chi-Ha chassis

• Five crew members
• 30 mm of penetration at any range and angle

Cons:

• Only fires high explosive rounds
• Poor turret traverse, just 5.1°/s
• Large shell drop (shells only travel 290 m/s)
• No roof-mounted anti-aircraft/infantry machine gun

History

The Short Barrel 120 mm Gun Tank was one variant produced late in the war for the Imperial Japanese Navy. They wanted a gun tank similar to the Type 2 Ho-I for close support, but with greater firepower. The standard 47 mm main tank gun was replaced with a short barrel naval 12 cm (120 mm) "anti-submarine" gun with a muzzle brake added. In addition, it had a small storage compartment added onto the back of the ShinHoTo Chi-Ha turret. Only "about a dozen" were produced for deployment by the Japanese Special Naval Landing Forces.

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.
