Supertest: M-III-Y Tier VIII American Heavy Tank

4 min read

The M-III-Y, like the higher-tier representatives of the Yoh branch, features the new reserve track mechanics. The vehicle has an additional track attached to the main one. This allows the vehicle to continue moving (although with a speed penalty) even if both main tracks are destroyed.

To the Supertest, the vehicle also comes with two top (90 mm and 105 mm) guns. The first gun is more accurate and has higher damage per minute, while the second one has higher damage per shot. The test will determine which configuration will be final—whether both guns or just one of them will remain.

The 90 mm gun causes 240 HP of damage per shot. The penetration of the main APCR shell is 223 mm, and the special HEAT shell has 290 mm of penetration. The gun’s accuracy is 0.37, with an aiming time of 2.1 s, and a reload time of 6.4 s. The 105 mm gun causes 320 HP of damage per shot. The penetration value of the main AP shell is 208 mm, and the penetration value of the special APCR shell is 245 mm. The gun’s accuracy is 0.39, has an aiming time of 2.3 s, and a reload time of 8.9 s.

Frontal turret armour measures up to 279 mm in thickness, and the durability of the vehicle is 1,450 HP. It has a top speed of 40 km/h and its specific power is 15 h.p./t. Like the higher-tier representatives of the branch, this vehicle has good gun depression/elevation angles: –10/20 degrees.

The M-III-Y has the same pros and cons as the Tier IX and X vehicles of the Yoh branch. The vehicle will play well on irregular terrains thanks to its good gun depression/elevation angles and solid turret. The vehicle’s good mobility and the reserve track mechanic will improve its survivability, even if an enemy tries to immobilize you, which will allow you to use different tactics and manoeuvres on the battlefield.

All characteristics are with a crew trained to 100% and subject to change before the final release.

A few other hidden stats that are not shared by Wargaming are the penalties you get with the new mechanics. Here are the currently hidden stats for these, and remember these are Supertest stats and might change in the future:

  • Suspension Repair Time
    • Main Track: 12.03 seconds
    • Reserve Track: 9.34 seconds
  • Penalty for one main track destroyed:
    • -25% maximum speed
    • -50% engine power
    • -50% suspension traverse speed
  • Penalty for both main tracks destroyed:
    • -50% maximum speed
    • -75% engine power
    • -75% suspension traverse speed
  • Penalty for repairing while on the move is 2 times bigger if speed is above 12km/h
  • The penalty is removed if the vehicle speed is less than 5 km/h
  • Hitpoints of the reserve track are 50% of the main tracks
