Description

The SU-122-54 is a rank V Soviet tank destroyer with a battle rating of 6.7 (AB/RB/SB). It was introduced in Update 1.49 (aka 1.70.1945) "Weapons of Victory". Featuring a T-54 chassis in a tank destroyer format and a 122 mm gun, the SU-122-54 presents an interesting vehicle for Rank V battles.

Usage in battles

The SU-122-54 could be described as a post-war ISU-122. Most characteristics of the vehicle point towards an effort to improve on both the good and bad features of the ISU. It features thickened and better-angled armour increased firepower with better crew ergonomics and new shells as well as improved mobility thanks to a redesigned chassis. This makes for a dangerous vehicle with more options in how to use than it's predecessors.

However, this all comes at the price of a high battle rating where it currently sits at. This makes for a quite difficult vehicle to use, as the opposition will be fierce. Be mindful of how you approach a situation. Charging blindly or sitting very far back won't yield great results, play as if it were a chess match and strategically choose your position and targets.

One way of playing the SU-122-54 is as a sniper, a task made easier with the inclusion of a APDS round that can pack a mean hit at penetration with a fire-rate decent for such sniper.

Pros and cons

Pros:

  • Strong gun that can fire HEAT-FS or APDS shells, unlike most other 122 mm gun-equipped tanks with a improved fire-rate
  • Fairly low silhouette
  • Has two 14.5 mm machine guns, good for warding off low-flying aircraft or light vehicles
  • Decently mobile
  • Has access to a rangefinder and NVD
  • Good top speed
  • Mantlet is 200 mm thick in total

Cons:

  • Long reload (16 seconds), though not as long as most other 122 mm
  • The protection is not adequate at close range
  • Restricted firing angles for the main guns, horizontally and vertically, due to casemate mounting
  • Lack of a turret means that if you get flanked, the tank is in serious trouble
  • Roof machine gun may sometime struggle to engage ground targets
  • Cupolas hits will injure respective crew members
  • Two loaders means the rate of fire suffers strongly in the event of a penetration
  • The armour is thick enough to hamper acceleration

History

The success of the T-54 tank in the early 1950s had the vehicle chassis used in many different variants for different roles. The roles range out from a self-propelled anti-aircraft gun, armoured recovery vehicle, bridge-layers, mine-clearers, flamethrowers, armoured personnel carriers, fire-fighting vehicles, and a self-propelled gun. The self-propelled gun, known as "Object 600", was a vehicle based off the T-54A design and carried the 122 mm gun infamous on the IS heavy tank series. The vehicle was known as the SU-122-54, but it has sometimes also be referred to as the IT-122 as well. The chassis was modified for the vehicle, with the large gap present between the first and second road wheels moved to between the third and fourth. The superstructure, like traditional designs, was built onto the hull and held the 122 mm gun. Secondary armament consisted of two KPVT heavy machine guns on coaxial and pintle-mount for anti-aircraft purposes. The general design was developed and built between 1955 and 1957, with a total of 77 units made with minor differences between each batch.

In-game description

The SU-122-54 self-propelled artillery mount was constructed on the basis of the T-54-55 medium tank from 1948 to 1951. It was intended first and foremost to play the role of an assault and antitank weapon. Plans were made for large-scale production of the SU-122, but starting in 1957 its release was curtailed due to a shift in the priorities of military production in favor of building missile weapons.

The SU-122-54 SPG was used by the Soviet Army until the second half of the 1960s, when it was removed from the army’s arsenal. A total of 77 SU-122-54 SPGs were produced.

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