Get ready to blast off! These four new tanks for World War II mode use the Rocket Booster mechanic for quick bursts of speed that will enhance your battle tactics.

When you play a heavy tank, often your job is to head to the frontline and take the hits that your teammates can’t. But heavy tanks in World War II mode usually aren’t built for speed, and getting into position can take some time.

Lucky for you, that’s not a problem for the latest additions to the Chinese Tech Tree. Welcome the rocket-boosted heavies!

• Tier VII: BZ-58
• Tier VIII: BZ-166
• Tier IX: BZ-68
• Tier X: BZ-75

Branching off from the Tier VI Type 58, this line features four vehicles designed for mid- to close-range combat. All of the tanks have low silhouettes, strong hulls and turrets, and high-caliber guns, but most importantly, they all feature the new Rocket Booster mechanic!

With this feature, you can blast ahead to seek cover, claim an ideal spot on the battlefield, escape enemies, and more.

And read on to learn more about each of these new tanks, available in the game starting February 25th!

BZ-58

• Nation: China
• Tier: VII
• Class: Heavy
• Research cost: 140,900 XP
• Purchase cost: 1,500,000 Silver
• Unlocked with the Type 58
• Gives access to the BZ-166

Development began in the late 1950s under the concept of creating "frontier-covering tanks." The project's distinctive feature was the combined hull: its frontal armor was cast with large upper glacis slopes, while the rest of the hull was welded. The vehicle was supposed to feature an autoloader in the rear recess of the turret. The design of the turret itself was combined; the welded base was complemented by cast blocks on the vehicle's cheeks. No prototypes were manufactured, and the project was canceled in 1970.

BZ-166

• Nation: China
• Tier: VIII
• Class: Heavy
• Research cost: 187,100 XP
• Purchase cost: 2,650,000 Silver
• Unlocked with the BZ-58
• Gives access to the BZ-68

In the 1960s, Chinese engineers tried to keep up with the leading tank-building countries, so their projects included design solutions of different schools. The distinctive features of the BZ-166 heavy tank were the "wavy" surfaces of the frontal hull armor and the jet boosters. According to the design concept, such armor was to increase the chances of ricochets. The jet boosters could increase the vehicle's speed for a short time. It was planned to equip the tank with 122 to 160 mm guns and use it for operations in fortified areas, as well as to destroy enemy engineering structures. It existed only in blueprints.

BZ-68

• Nation: China
• Tier: IX
• Class: Heavy
• Research cost: 252,000 XP
• Purchase cost: 3,700,000 Silver
• Unlocked with the BZ-166
• Gives access to the BZ-75

One of the variants of the "frontier-covering tank," this vehicle featured quite a simple yet technologically advanced hull and turret welded from flat plates. It was supposed to mount two solid-propellant jet boosters for crossing tough terrain, as well as for self-recovery. No prototypes were manufactured. The project was canceled during the design phase in 1969.

BZ-75

• Nation: China
• Tier: X
• Class: Heavy
• Research cost: 368,300 XP
• Purchase cost: 6,100,000 Silver
• Unlocked with the BZ-68
• End of the branch

In the 1960s, amid tense relations with the U.S.S.R., China came up with the concept of creating "frontier-covering forces." The main firepower of this formation was to be units with "frontier-covering tanks" in service. One of the projects for such vehicles was the BZ-75, developed in 1975 using the experience gained developing the WZ-111 heavy tank. While working on the turret, engineers incorporated the design features of the WZ-1224 project. No BZ-75 prototypes were manufactured.
