Description

The T-55A is a rank VI Russian medium tank with a battle rating of 8.3 (AB/RB/SB). It was introduced in Update 1.69 "Regia Aeronautica".

After active development of nuclear weapons, the predecessor of T-55 (T-54) was tested against nuclear charges. It was evaluated that the crew could survive only at distances of over 700m, so it was decided to create a new tank that would have a nuclear, biological and chemical (NBC) protection system, or Protivoatomnaya Zashchita (PAZ). The initial designs for this tank were completed in 1956, however, that was without additional NBC protection. In 1961, the development of an NBC system began, and it was introduced in the new T-55A variant. Among other upgrades, the T-55 had an increased ammunition supply with 18 more rounds being stored in the fuel tanks.

T-55 became a replacement for Soviet heavy tanks (IS series and the T-10), something that is evident in War Thunder as well. Armour was sacrificed for better mobility and a better gun. Currently, the T-55A is one of the only vehicles at rank VI to have an APHE shell, which easily one-shots most vehicles from the sides and some from the front (notably, leopards). Unfortunately, the T-55A is relatively slow compared to other medium tanks around battle rating 8.3.

General info

Survivability and armour

At battle ratings over 8.0, armour becomes almost obsolete. The T-55A has moderate frontal protection, with 100 mm plates for UFP and LFP placed at angles 59° and 56° respectively; effective thickness frontally comes up to ~180 mm and ~200 mm, respectively. At a perfect angle, you can bring the effective thickness to ~200 mm and ~220 mm for UFP and LFP, while having ~250 mm of protection at your angled sides. However, the additional 20 mm of armour will rarely save you from top-rank APFSDS, or even APDS, shells.

As for the turret, the T-55A has slightly less protection than the T-62, and combined with a generally larger turret, it is generally easier for your opponents to hit and penetrate your turret. The thinnest spots are right next to the cannon breach, at 200 mm, which rather slowly becomes over 300 mm as you move further away from the breach.

Your weakest side is the right-hand side when looking at the T-55A, frontally, because 3 of your 4 crew are located in a row there. A well placed APFSDS shot to the top-right of the UFP will one-shot the T-55A, see diagram on the right.

Mobility

The maximum speed that the T-55A can reach is listed as 56 km/h (AB) and 50 km/h (RB/SB). That is ~15 km/h slower than the Leopard A1A1. However, the amount of firepower that the T-55A brings to the battlefield, coupled together with the ability to withstand shots sometimes, that speed is decent. Backwards, the T-55A can go at up to -7 km/h, which won't let you back out of tricky situations often.

The T-55A cannot turn in neutral gear, which makes it difficult to maneuver in close-quarter encounters, which often occur in the cities. The acceleration is good, the T-55A can get to 25 km/h from a standstill on flat, rough terrain in a few seconds, and turning is decent on flat ground.

Armaments

Main armament

Main article: D-10T2S (100 mm)

The T-55A houses a 100 mm D-10T2S rifled anti-tank gun, which is equipped with an ejector and two-plane stabilizer arms. In-game, the T-55A has a 10.3 s reload rate, which is similar to its predecessor, the T-62. This rate of fire doesn't allow the T-55A to rush into battle and fend off waves of Leopards or M48s/M60s, but it is sufficient to defeat one or two opponents in quick succession with good shot placements, granted you shoot first.

The stock round (3BM-8, APDS) allows the T-55A to penetrate MBT-70 and KPz-70 frontally, as well as deal with all other major threats, notably the Leopards (which you can penetrate anywhere), and Chieftains (LFP, or UFP/LFP with the APFSDS round). One of the major advantages that the T-55A has over the majority of rank VI vehicles is its APCBC shell, which has the potential to one-shot any opponent if it penetrates. It is advised to flank your enemies and when given the opportunity, easily destroy oncoming enemies with this round.

Machine guns

Main article: DShK (12.7 mm)

The T-55A has a roof-mounted 12.7 mm DShK machine gun, which allows it to fight low-flying aircraft or helicopters. However, it is not effective against jets. It is recommended to use this machine gun against lightly armoured ground targets and to check whether or not a tank is alive or not, by shooting its tracks (which can also be done with the coaxial machine gun).

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

Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in a bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".

Pros:

  • Very varied choice of ammunition, notably the APCBC shell.
  • Decent speed and mobility.
  • Decent reload, which allows the T-55A to defend itself against a couple of enemies in succession.
  • A roof-mounted machine gun that allows the T-55A to shoot at low-flying planes.

Cons:

  • Right-hand side (when looking at the T-55 frontally) allows to knock out 3 out of 4 crew.
  • Armour is increasingly obsolete around this battle rating, weighing the tank down.
  • Poor reverse speed.
  • No neutral steering.

History

Describe the history of the creation and combat usage of the ground vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/ History" (example: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref>, as well as adding them at the end of the article. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === Encyclopedia Info ===, also if applicable).

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
