The '''{{Specs|name}} / Short 12cm SPG''' ({{Annotation|短十二糎自走砲|Tan-Jūni Senchimētoru Ji Hashi-Hō}}) is a later iteration of the [[Chi-Ha]] with a modified turret coming from the [[Chi-Ha Kai]], boasting a [[Navy short gun (120 mm)]] meant to defend naval bases and merchant ships in a multipurpose role. The Navy's modification of the Chi-Ha was meant to mimic the role of the Army's [[Ho-I]] tank to support infantry as a gun tank during the defense of the homeland.

The {{PAGENAME}} 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 (Family)|Chi-Ha]] chassis but loses the turret rotation speed due the added weight of the gun.
 
  
 +
The {{PAGENAME}} was introduced along with the initial Japanese Ground Forces tree in [[Update 1.65 "Way of the Samurai"]] as a pre-order [[wt:en/news/4379-japanese-pre-order-packs-en|premium pack]]. It packs a relatively powerful 120 mm cannon that can destroy most enemies with one shot. However, it has a considerable reload time of 10s aced, poor turret traverse, and low shell velocity that make it hard to aim and fight with. It will be able to destroy the lightest targets with near misses, and will need some aim on more armoured targets trying to splash the explosive mass into the bottom or top armour of tanks.

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 gun from the {{PAGENAME}} 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.

The 120 mm Navy short gun is built to deal with submarines and close range naval combat, and that does translate over in-game as a gun that have a very low muzzle velocity, which on the bright side can be used to shoot at vehicles over cover.
 +
 
 +
The gun can only fire an HE round by default. However, the shell contains 2.64 kg of TNT equivalent, which is enough to cause a lethal overpressure damage against almost any enemy the tank has to face at its BR.
 +
 
 +
While the shell is certainly powerful, it is not as powerful as the [[Ho-Ro]]'s 150 mm howitzer rounds. This means careful aim is still needed when facing a more well-armoured opponents. Against these targets, aim at any deflective angles that can cause the explosion effect to deflect on the weak hull roof.

Because the {{PAGENAME}} 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.{{clear}}

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 [[wikipedia:12_cm/12_short_naval_gun?|12cm/12 short naval gun]]. Additionally, there was a small storage compartment added onto the back of the ShinHoTo Chi-Ha turret.

These vehicles would most likely have seen service in defense of the homeland next to the SNLF infantry. But in-case that these tanks would be required to move to forward islands, they would most likely be transport by [[Daihatsu-class Landing Craft]]'s just like the infantry accompanied and escorted by the Amphibious tanks during landings.

Description

The Type 97 Chi-Ha Short Gun / Short 12cm SPG (短十二糎自走砲) is a later iteration of the Chi-Ha with a modified turret coming from the Chi-Ha Kai, boasting a Navy short gun (120 mm) meant to defend naval bases and merchant ships in a multipurpose role. The Navy's modification of the Chi-Ha was meant to mimic the role of the Army's Ho-I tank to support infantry as a gun tank during the defense of the homeland.

The Chi-Ha Short Gun was introduced along with the initial Japanese Ground Forces tree in Update 1.65 "Way of the Samurai" as a pre-order premium pack. It packs a relatively powerful 120 mm cannon that can destroy most enemies with one shot. However, it has a considerable reload time of 10s aced, poor turret traverse, and low shell velocity that make it hard to aim and fight with. It will be able to destroy the lightest targets with near misses, and will need some aim on more armoured targets trying to splash the explosive mass into the bottom or top armour of tanks.

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.

Main article: Navy short gun (120 mm)

The 120 mm Navy short gun is built to deal with submarines and close range naval combat, and that does translate over in-game as a gun that have a very low muzzle velocity, which on the bright side can be used to shoot at vehicles over cover.

The gun can only fire an HE round by default. However, the shell contains 2.64 kg of TNT equivalent, which is enough to cause a lethal overpressure damage against almost any enemy the tank has to face at its BR.

While the shell is certainly powerful, it is not as powerful as the Ho-Ro's 150 mm howitzer rounds. This means careful aim is still needed when facing a more well-armoured opponents. Against these targets, aim at any deflective angles that can cause the explosion effect to deflect on the weak hull roof.

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 awfully slow turret traverse and poor shell trajectory harming the tank's combat effectiveness. However, with each shell having 2.64 kg of TNT equivalent of explosives, it can easily deal overpressure damage against most tank it will face.

Most lightly-armoured vehicles and tanks with less than 30 mm of armour will be able to be destroyed from crew knock-out wherever you hit them. But when you start opposing medium to heavy tanks, you should fall back for friendlies to deal with the target. It might be possible fire a shot to deal overpressure damage against weak hull roof, 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
  • Ten-seconds reload with a 120 mm cannon
  • Huge explosive mass for 120 mm HE shell means it can destroy every tank it faces via overpressure
  • Five crew members

Cons:

  • Slow reload compared to cannons commonly met at this BR (37 to 75 mm)
  • Only fires high explosive rounds
  • As the shell is much less effective than the 150 mm howitzers, it requires some knowledge for where to aim on enemy's tanks to cause overpressure effect
  • Poor turret traverse, just 5.1°/s
  • Very slow muzzle velocity (290 m/s) causes large shell drop

History

Main article: History of the Type 97 Chi-Ha

Development

The Chi-Ha Short Gun, designated the Short 12 cm Self-propelled artillery (短十 二糎 自走砲) 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 with greater firepower to support the 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 brake, 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 is that only a dozen or so vehicles were built and all were assigned to the Yokosuka No. 16 Special Land Battle Corps. 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 have seen service in defense of the homeland next to the SNLF infantry. But in-case that these tanks would be required to move to forward islands, they would most likely be transport by Daihatsu-class Landing Craft's just like the infantry accompanied and escorted by the Amphibious tanks during landings.

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