Type 99 (75 mm)
|This page is about the Japanese cannon Type 99 (75 mm). For other uses, see Type 99 (Disambiguation).|
The 75 mm Type 99 tank gun (Type 2 Ho-I medium tank.) is a tank-mounted 75 mm cannon, found in-game as the main armament of the Japanese
Vehicles equipped with this weapon
The cannon itself, though designed as a pure close support weapon, is still quite usable in tank combat. However the low muzzle velocity makes the cannon rather unusable as a means of sniping, and is therefore more employable in close quarters combat.
Due to the weak penetration of the shells, it is also hard to destroy any mildly armoured target, meaning that often weak spots will have to be exploited or external components be targeted instead, making heavy use of the explosive mass that the shells carry.
It is therefore a very potent supportive gun, meaning that in a team combined with other types of tanks this gun may excel due to the very different characteristics it displays.
- Type 95 APHE: With only 43 mm of penetration, the APHE is a pretty tricky shell to employ, as it will struggle to penetrate most targets at its rank, and is only usable against most reserve tanks in the most lucky engagements. Though it contains 460 g of TNT, making every penetration highly dangerous and deadly.
- Type 94 HE: The stock HE shell, namely here the Type 94, is pretty useless as it has only 12 mm of penetration, completely unusable in fighting armoured fighting vehicles. However it is highly usable against vehicles that have either very slight armour or no armour (for example most low tier anti-air vehicles). It can also cause a reasonable overpressure effect, though that is not a great means of destroying most vehicles. It can still be used to damage external components as it has 810 g TNT.
- Type 2 HEAT: The Type 2 HEAT gives the cannon a small advantage that should not be underestimated. The acceptable penetration of 90 mm at any range is able to get through almost every tank at its tier if not angled. The only drawback is the underwhelming post-penetration damage.
- Type 90 Smoke: At lower tiers, the Type 90 smoke shell can be highly usable as most tanks do not feature smoke launchers, and you can help in engagements by either hiding retreats or causing confusion in enemy lines during firefights, obscuring positions.

Pros and cons
- Great post-penetration damage on APHE
- Availability of early HEAT rounds
- Low penetration of only 43 mm on APHE (excluding HEAT)
- Slow muzzle velocity
In July 1937, the technical bureau of the army was planning on future weaponry, including later employed 47 mm and 57 mm guns, however it also was thinking of a short 75 mm cannon for supportive functions. In December 1940, a prototype was manufactured in the Osaka army arsenal. In the end, only a few examples of the modified Type 99 cannon were built, as it was never heavily employed in combat due to the shortage of materials and concentration on different types of tanks, as well as other sectors of the army and navy.
The development of the corresponding Type 2 Ho-I ceded too, as it was already obsolete by the time the project had ended, though the few vehicles that were built were then integrated in the home defence.
The gun itself however was a potent 75 mm cannon at the time it was considered to be employed, and was certainly effective against defensive structures and infantry. Though it does not possess overwhelming penetration with only 43 mm penetration at 10 m with the Type 95 APHE, it can be used for anti-tank combat effectively.
Due to being constructed as a support gun, it features a slow muzzle velocity, therefore it cannot be handled as a cannon that is truly omnipotent. However, the big advantage is the explosive mass in the shells, with even the APHE sporting 460 g TNT of explosive mass, meaning that when the shell penetrates, it is sure to do considerable damage. Another advantage is the availability of early HEAT, being the Type 2 shell, giving the cannon 90 mm of penetration at any range, though limiting the damage done. Smoke shells are also available.
