Supertest: BZ-75 Tier X Tech Tree Chinese Heavy Tank

3 min read

The first researchable vehicle from the upcoming 🇨🇳 Chinese branch of heavy tanks with rocket booster mechanics (try saying that three times fast!) has arrived on supertest: X 🇨🇳 BZ-75.

Beyond the obvious inclusion of rocket booster mechanics, the vehicle notably features a choice between two guns: one standard 152 mm gun, and one howitzer 180 mm gun.

Description from the EU Supertest forums:

The BZ-75 is well protected for its tier: Its frontal hull armor reaches 200 mm, and the frontal turret armor is up to 330 mm. Its durability is 2,500 HP. The top forward speed is 35 km/h, with a reverse speed of 15 km/h. Its specific power of 12.9 h.p./t means that mobility is not great, but keep in mind that the BZ-75 is a heavy tank with jet booster mechanics. When activated, these boosters double the engine power and increase the top forward speed.

Another distinctive feature of the BZ-75 is the ability to choose between two guns.

The 152 mm gun can cause 650 HP of damage per shot. Armor penetration with a standard shell is 258 mm, while a special HEAT shell penetrates 319 mm of armor. Its aiming time is 2.7 seconds and its reload time is 17 seconds, while the dispersion is 0.4 meters.

The 180 mm howitzer gun can deliver 1,600 HP of damage per shot with a standard shell, with 75 mm of penetration. The damage per shot of a special shell is 1,050 HP, with 225 mm of penetration. Its aiming time is 3 seconds and its reload time is 30 seconds, while the dispersion is 0.4 meters.

The standard HE shell has low velocity and penetration parameters but good damage upon penetration and when the fragments hit weak spots upon non-penetration. The special HE shell has improved velocity and penetration, but its damage upon penetration is significantly lower than that of the standard one. This shell hardly causes any damage to vehicles if it explodes on the armor. To reach maximum effectiveness in battle, you need to alternate shell types wisely depending on the situation and enemy vehicles.


At the start of the battle, the boosters will take 5 seconds to load and prepare for use. You’ll be notified of this in a corresponding indicator bar. After that, the booster can be activated. Once activated, the tank will receive a brief boost to its engine power and top forward speed, as well as its initial momentum, allowing the heavy combat vehicle to accelerate.

When jet boosters are in use, the vehicle will have difficulty turning and moving in reverse. You will not be able to cancel the effect until one charge is fully depleted. After that, you will need to wait 5 seconds until the boosters are reloaded.

The boost effect will last 10 seconds and can be used up to six times per battle with the given amount of jet fuel (for the BZ-75). After the last use, the indicator will go out, notifying you of your empty fuel tanks, and you won’t be able to use the jet boosters for the remainder of the battle.

When used correctly, this mechanic will allow you to quickly cross dangerous areas at critical moments in battle, ram lightly armored targets more efficiently, or occupy key positions faster. Overall, there are plenty of ways to adapt this mechanic to your tactics and playstyle.
