Description
The Heavy Tank T30 is a premium gift rank IV American heavy tank
with a battle rating of 6.7 (AB/RB/SB). It was introduced in Update 1.85 "Supersonic" in the 2018 "Festive Quest" that took place between 21 December 2018 to 14 January 2019. It was obtainable via completing 10 Christmas Toys for tankers. It could also be purchased on the Gaijin market after the event was over.
The T30 was a World War II American tank project developed to counter new German tanks, such as Tiger I, Tiger II, and tank destroyers, such as the Jagdtiger, or Soviet heavy tanks, such as IS-1 or IS-2. The T30 was designed at the same time as the T29 Heavy Tank. However, it had a 155mm gun mounted on the same hull and turret as the T29 and T34 heavy tanks.
General info
Survivability and armour
Armour type:
- Rolled homogeneous armour (hull roof, sides & rear - engine bay, hull bottom)
- Cast homogeneous armour (hull front, sides & roof - fighting compartment, turret, gun mantlet, cupola)
| Armour | Front (Slope angle) | Sides | Rear | Roof |
|---|---|---|---|---|
| Hull | 102 mm (55°) Front glacis 70.25 mm (61°) Lower glacis - centre 70.25 mm (40°) Lower glacis - sides 102.5 mm (5°) MG housing 88 mm (sphere) MG port |
76.2 mm Front half 51 mm Rear half |
51 mm (5°) Top 51 mm (60°) Bottom |
38.1 mm (57°-81°) Front 38.1 mm Rear |
| Turret | 203 mm Gun mantlet 158.7 mm Gun mantlet frame |
158.7 mm | 102 mm Vertical part 50 mm (71°) Turret ring area |
38.1 mm (79°) |
| Cupola | 152.45 mm (45°) | 38.1 mm (79°) | ||
Notes:
- Suspension wheels are 20 mm thick while tracks are 30 mm thick.
- Mudguards are 4 mm thick.
- Frontally, the MG housing (around the MG port) as well as the lower glacis are weak spots on the T30.
- The bottom of the hull is only 25.4 mm thick, making it vulnerable to powerful HE shells shot under the belly.
Mobility
| Game Mode | Max Speed (km/h) | Weight (tons) | Engine power (horsepower) | Power-to-weight ratio (hp/ton) | |||
|---|---|---|---|---|---|---|---|
| Forward | Reverse | Stock | Upgraded | Stock | Upgraded | ||
| Arcade | 38 | 15 | 65.8 | 1046 | 1,545 | 15.9 | 23.48 |
| Realistic | 36 | 14 | 716 | 810 | 10.88 | 12.31 | |
The T30's mobility is good for the role it fulfills. Its acceleration and maximum speed are good for a heavy tank. While the reverse speed is average, it isn't a handicap. And the T30 can brake quickly in spite of its weight. Neutral steering allows you to turn your hull towards flanking enemies relatively quickly on the spot. The offroad mobility is good: the T30 can reach 15 km/h when climbing uphill from idling and 21 km/h when fording. Due to its weight, the tank's mobility is unhindered by obstacles.

Ammunition
The available choice of ammunition focuses on heavily armoured targets:
- M112B1: APBC; an armour-piercing ballistic capped shell with high explosive mass and good penetration power that will one-shot any tank it penetrates.
- T29E1: APCBC; an armour-piercing capped shell with a ballistic cap offering an increased penetration compared to the M112B1.
- M107: HE; a powerful high-explosive shell useful to destroy all enemy vehicles and even open and lightly armoured vehicles indirectly with the blast.
- M110: Smoke; useful to blind enemy vehicles that are too remote for you to disable so that you can progress towards objectives.

Notes:
- The T30 uses two-piece ammunition, composed of projectiles (yellow) and propellant bags (orange). Both have separate racks.
- Racks 3 and 4 are first stage ammo racks. They total 7 shells for projectiles and 6 shells for propellant bags.
- These racks get filled first when loading up the tank and are also emptied early: the rack depletion order at full capacity is: 4 - 3 - 1 - 2.

These heavy machineguns can be extremely useful for gauging distance measurements (coaxial), engaging lightly armoured vehicles or shooting down enemy aircraft (pintle).
Usage in battles
Despite its labeling as a heavy tank, the T30 plays more like a tank destroyer than anything else. This is as a direct result from the 155's excellent ability to over-match most enemy armor it faces. Due to the reload rate of the tank, it is best to play a similar play-style to the KV-2s.

Pros and cons
Pros:
- Inherits the great armour layout of the T29
- Huge 155 mm gun that packs a devastating punch
- HE shell is great at taking out heavily armoured tanks if the explosion occurs over the turret, or under the hull
- Because of the slow shell velocity, this is one of the few tanks that's really good at hitting targets behind cover
- Despite the massive breech, the tank still has 10 degrees of gun depression
- Has two .50 cal machine guns that can rip apart lightly armoured vehicles
Cons:
- Has one of the slowest reloads in the game, an ace crew will only reload the gun every 29.9 seconds
- Despite the massive gun, the top APCBC shell only has 199 mm of pen at point blank range
- Bad shell velocity makes hitting moving targets at ranges exceeding 500 meters a challenge
- Has one less .50 cal machine gun than the T29 and T34
- The first stage ammo rack means there is almost always ammo in the turret
- Is simply a worse T29
History
In 1944, the Army requested 4 prototypes for heavy tanks, two armed with a 105 mm gun and two armed with a 155 mm gun. The intention was to create vehicles that could face enemy heavy tanks on even terms, or even advantageous terms. The vehicles armed with the 105 mm gun were designated T29, and the two armed with a 155 mm gun were designated T30.
The armament of the T30, a 155 mm T7 L/40 gun, was one of the largest guns ever fitted to an armored fighting vehicle made in the United States. The gun was carried in a tall, long turret with rounded edges. The height of the turret was quite necessary, as the size of the gun and its ammunition required a standing loader. The hull of the T30 was the same as the T29. It was a lengthened version of the T26E3 chassis. The armor of the T30 was quite thick, and the hull was also well angled, as one of the requirements for the design was protection from the German long 88 mm anti-tank gun. The T30 carried a crew of six men. These were the driver, commander, bow machine gunner, gunner, and two loaders. One loader moved the crane that placed the shell, and the other used the rammer that put the shell into the breech. The gun could only be loaded at certain angles. The T30 saw an upgrade, called the T30E1, which added an automatic loading system, which moved the gun to the correct position, loaded the shell, and moved the gun back to the firing position. A hatch was added to the rear of the turret to allow the ejection of shell casings after firing.
World War 2 ended before the heavy tank designs (T28, T29, T30, T32, T34) could enter service, and the development of these vehicles ended, but the development of these heavy tank designs provided experience that proved useful when designing the M103 heavy tank during the Cold War.
