Description

The TO-55 was a modification of the T-55 fitted with a flamethrower, intended to assist infantry in pushing against enemy defensive positions during battle, while allowing for increased survivability of such a weapon system when compared to flamethrowers carried by infantry. The original tank turret was modified by incorporating an ATO-200 flamethrower coaxial with the main armament. The standard ammunition stowage in the bow next to the driver was modified to accommodate a flammable liquid tank with a capacity of 460 litres. The flamethrower was aimed by rotating the entire turret, and ignited by pyrotechnic charges. Instead of being manually controlled, the rate of fuel consumption was standard, averaging 36 litres per burst of flame. The flamethrower had a maximum effective range of about 200 metres and an initial muzzle velocity of about 100 meters per second.

Introduced in Update "Sons of Attila", the TO-55 resembles the standard T-55 variant in appearance, but its coaxial armament has been replaced by a flame projector. The flamethrower, while appealing, has a very limited range and is only useful for open/lightly armoured vehicles, making it a very situational armament. However, being built on the basis of the T-55, the TO-55 is a tried-and-true platform with dependable armour and adequate firepower, and can still shine in the right hands with good tactics and careful planning.

Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.

Usage in battles

Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons

Pros:

• Wonderful APHECBC shell to one-shot enemies while flanking
• Have stabilizer which help you aim the gun faster, useful for corner peaking
• Various smoke options, with ESS that can be used when retreating and smoke shells to capture points in the open
• Better engine power than T-54
• Flamethrower can help blind enemy if you miss your shot in a fight
• Flamethrower model can help block some shot to the turret

Cons:

• Low main gun ammunition
• First stage ammo rack gets moved to the turret, thus most of the time there will be ammo in the turret which increases the chance to be destroy when hit even when you hull down.
• APHECBC have hard time penetrating other MBTs from the front, requiring targeting of weak points.
• Subpar turret rotation

History

The predecessor of the Soviet TO-55 was the TO-54 tank, developed on the basis of the T-54 medium tank at the Malyshev Factory. In 1957, a new flamethrower tank was developed on the chassis of the T-55 tank, which used the more advanced ATO-200 flamethrower. TO-55 successfully passed the tests and was put into service in 1960. The tank was mass-produced in Omsk and Kharkov, a total of 830 TO-55 units were produced. The flamethrower tank was in service with the army until 1997.
