This page is about the premium Japanese medium tank Chi-Ha Short Gun. For other uses, see Chi-Ha (Family).

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.

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
  • Typically, if the round penetrates, it kills
  • Ten-second reload (Expert Crew) with a 120 mm cannon
  • 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

Development (Chi-Ha)

Type 97 Chi-Ha Medium Tank

The Imperial Japanese Army's main tank was the Type 89, adopted in 1929, but it was deemed obsolete as of 1935 and the IJA wanted something up to par with their battle style. The Type 89's main fault was its low overall road speed, which was unable to keep up with motorized infantry. Thus, the development of a new medium tank commenced with the goal of improved overall speed, low weight, and low cost.[1]

Two tank designs were developed with these specifications, both were produced by Mitsubishi. The first was the Chi-Ha which was powered by a 170 hp diesel engine. The second was Chi-Ni, which was lighter, cheaper, and powered by a 135 hp diesel engine. The IJA was to choose in 1937, when the Second Sino-Japanese War broke out. This war increased the IJA's budget and thus they decided to pick the better of the two designs. This led to the finalization of the Type 97 Chi-Ha medium tank. Production started in 1938 all the way to 1942 for a total of 1,162 tanks produced.[1][2]

Development (Chi-Ha Kai)

Japanese Army observers had watched tank developments in Europe and studied as avidly as any European military the operational experiences gained by German, Soviet, and Italian tanks in the Spanish Civil War (1936-1939). In order to improve the anti-tank capability of the Type 97 Chi-Ha medium tank, a new enlarged three-man turret armed with a high-velocity 47 mm gun was combined with the Chi-Ha's hull; hence the new name Type 97-Kai ("improved") or ShinHoTo Chi-Ha ("new turret")[1]. In 1942, it replaced the original model Type 97 in production. In addition "about 300" of the Type 97 tanks with the older model turret and 57 mm main gun were converted.

Development (Chi-Ha Short Gun)

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.
