Type 74 (G) (Type 74 Kai) : 74式戦車(G) / 74式戦車改

74mbt_18.jpg

 

This is the last model of "Type 74". Prototype renovation is 1992, and formal renovation is 1993. 

Formal renovation constructed only 4 tanks, and they belong to Fuji School Brigade, Tank School Unit (1st training units since 2012~)  . Its cereal number is "95-6XXX".

 

in 1990, JGSDF develop "Type 90 tank". But this tank is too heavy (over 50 ton!), so it deployed only Hokkaido island and Fuji school brigade. So they need more light and useful tank for Honshu and Kyushu.

 

Its difference to Type 74 (early?) in game is below

  • Thermal sleeve (since model D)
  • New APFSDS and HEATMP (since 1990s)
  • Passive IR sensor
  • Side-skirt attachment (removed)
  • Truck detachment prevention ring on drive wheel
  • Smoke launcher interlock to laser-detector
  • Change gear ratio: Back speed is improved.

 

But, this modification is too expensive, so Type 74 G built only 5 (1 prototype and 4 production). Now, Type 74s in Honshu are replacing to Type 16 MCV. They don't have money!

 

* Type 74 G = Type 74 Kai. please be carefully!

 

Edit: Type 74 G Side-skirt under the test.

I don't know where is this photo source, but this is very curious.

What are the penetration values of the rounds? Didn´t see it anywhere and my Japanese is a bit rusty... It could replace the Type 74 at 8.7 (which would go to 8.3) to create a rather decent loadout (althoug ATGM support would stil be missing but we wil see what 1.79 has to offer). +1

Wasn't the 74G intended to have additional armour packages in addition to electronics upgrades?

iirc other than the enlarged ring over the drive sprocket there's not much different between the G's kept in service and Type 74 E/F's externally

This Type 74 is used for urban warfare test or display by JGSDF 1st Tank Battalion.

Look at well it’s drive sprocket: there aren’t additional ring. And, Type 74 G is used by only Fuji Schools.

 

Also, Type 74 (G) = Type 74 Kai

In Japanese, 74式戦車(G) = 74式戦車 (改修)

There aren’t “Type 74 G Kai”

 

And, STB early have improved electronics (remote machine gun/ full electric control FCS etc.) But production models did not have it: it’s too expensive.

It’s a top secret:(

These shells used for mostly tanks in Mainland of Japan and Type 16 MCV ( Type 16 is replacing Type 74 now)

 

combat1.sakura.ne.jp/74SHIKI.htm

This website says in guesses: 

Type 93 APFSDS penetration is 414mm/ 4000m.

Type 91 HEAT-MP penetration is better than M456.

I don't see the point of adding the G version since the in-game Type 74 has already both M456 HEAT and M735 APFSDS rounds.

Regarding its new thermal sight, Gaijin doesn't even bother to include authentic tank sights in the game.

 

The Type 74 fitted with the add-on armor and the Type 93 APFSDS should be a more relevant suggestion.

No worries ^^.

Anyway-+1 for me for this.Japan needs everything they can get,because they don´t have much.

As for the penetration of the APFSDS-if the values for the penetrator dimension are accurate,i´d say penetration at 90° is probably somewhere around 450-460mm,and up to 250-270 @ 60°.

@Conraire for example could probably give you a far more accurate estimation,though.

I'd need a velocity table to be sure, or at least something that gave muzzle velocity, and velocity at say 2000m..

Regarding the penetration of the Type 93 APFSDS shell, @Shimamurider calculated the penetration here. I don't know how correct it is, but it certainly seems thorough. The humongous difference between the maximum and minimum values makes me question it a bit though.

  • At 0 kilometers, the penetration was calculated to be between 428~499mm of penetration at 1501 m/s
  • At 1000 kilometers, the penetration was calculated to be between 407~483mm of penetration at 1451 m/s
  • At 2000 kilometers, the penetration was calculated to be between 388~466mm of penetration at 1401 m/s
