?Development was started in 1948. The T-54 tank was used as a basis for this tank destroyer. The vehicle entered service in 1954. Mass production was launched in 1955, with a total of 100 vehicles manufactured.+ 
 +Also known under designation IT-122, the SU-122-54 was based on the T54 chassis. Developed started in 1949, with a goal to design a long range tank destroyer. Between 1955 and 1957, 77 vehicles were built with minor differences between production lots (different commander's cupola etc.). The SU-122-54 had a modified T-54 chassis, with small spaces between the first, second and fourth pair of wheels and a large gap between the third, similar to the T-62's and a superstructure, built into the hull, housing the 122 mm M-62-T gun for which the vehicle carries 32 rounds. The secondary armament consisted of two KPVT heavy machine guns, one mounted as an anti-aircraft machine gun near the commander's hatch and the other mounted coaxially with the main gun. The vehicle carried 600 rounds for the machine guns. The main gun has a fume extractor positioned right behind the muzzle brake, although some vehicles were built without fume extractor. Other variations included a different commander's copula. The SU-122-54 was rarely observed during its service life in the 1950's and early 1960's and became generally known only after ARV versions (designated TOP) were seen during Red Square parades during the 1970’s with the armament removed and the front glacis plated over. In 1954 the SU-122-54 was experimentally tested with a more powerful 122mm M-62S tank gun, but this version did not reach series production.

Specifically, the mismatch in crew values caused by commander's 10% crew skill bonus. Outside of a crew of 1 commander only, 100% crew is a fiction. The client values, given for 100% crew, will normally be taken into battle with 110% crew skill members aside from specific functions, causing their actual performance to deviate from the expected client value. These differences are taken into account in tooltip boxes.

Player Opinion

Pros and Cons

Pros:


  • Good DPM on the top gun
  • Low profile
  • Great maneuverability
  • Small silhouette; good camouflage rating


Cons:


  • Weak armor
  • Modules get damaged easily
  • Lowest HP of all tier IX TD's


Performance

The SU-122-54 is a versatile tank destroyer, being able to fulfill multiple roles during the course of battle. Excelling both at sniping or due to the mobility, supporting fast assaults or flanking operations. The vehicle has a high camouflage rating due to its low profile, and can thus move swiftly around the battlefield without being spotted. When supporting in offensive operations, the low HP doesn't allow the SU-122-54 to be the first going into battle. Stay behind friendlies and act as a stealthy support vehicle.


Early Research

Thankfully, the top gun from the SU-101 is also available on the SU-122-54, so the first thing you'll want to do is mount the 100 mm D-54S. In this state, though not impossible, you'll find it difficult to engage heavily armoured vehicles from the front. Unfortunately, you cannot mount the 122 mm M62-C2 before upgrading the suspension, even though it appears like you might be able to if you don't mount any equipment -- the stock suspension can almost support the top gun, but not quite. Until you have the M62-C2, you should position yourself to engage the flanks of enemy attacks. After the suspension, research the 122 mm M62-C2, followed by the top engine. Whether you want to research the top radio is a matter of opinion.
