The SU-122P is a premium rank IV Soviet tank destroyer with a battle rating of 6.0 (AB/RB/SB). It was introduced in Update 1.41.
Survivability and armour
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
An important note when engaging tanks, especially Tiger I's, is that, with the implementation of volumetric shells, you can no longer expect your shells to pierce through small openings or right past an obstacle. The large 122 mm calibre of your shells will result in it catching on an armour plate's edge very often, losing all of its penetration. For example, a Tiger I has some edges that can absorb your shell unexpectedly, despite having flat armour. Thus you must always make sure that where you are aiming at is absolutely free of obstruction, or it may result in a non-penetration or a ricochet. This can be seen in the diagram to the right.
Specific Enemies Worth Noting
These are common vehicles you will see in this tank:
- ☠ T32 - You have to go for the MG port in the lower left of the UFP, otherwise you can only penetrate the side armour or the rear.
- ☠ T28 - You can only penetrate the cupolas on top of the tank. If they're hidden or you are unsure about the shot, you can try hitting the cannon barrel and running away.
- ☠ Ferdinand - Go for the angled armour at the sides of the lower front plate (below the casemate, but above the lowest plates), this will disable Ferdinand's engine and/or driver, so you can flank and finish it off.
- ☠ Jagdtiger - You cannot reliably penetrate or damage this tank frontally. You can try disabling the cannon barrel, and then flanking is your best option (or running away).
- ☠ Conqueror - Shoot the hull, don't shoot the turret.
- ☠ Ho-Ri Production - You cannot reliably penetrate or damage this tank frontally. You can try disabling the cannon barrel and then flanking is your best option (or running).
- ☠ AMX-50 Foch - You cannot reliably penetrate or damage this tank frontally. You can try disabling the cannon barrel and then flanking is your best option (or running).
- T34 / T29 - Turret cheeks can work, although it's best to go for the LFP because the ammo storage is very low in the tank. If you don't see the LFP, try going just below the turret ring, where the driver sits.
- Tiger II (H) / Panther II - You can easily penetrate the turret cheeks with BR-471B.
- Panther D, A, G, F - You can penetrate the UFP
- Tortoise - Shoot to the right of the gun of the Tortoise, when you see it head-on if shoot on the left plate there is a chance of a one-shot
- AMX-50 Surbaissé - Go for the LFP.
Pros and cons
- One of the fastest reloading Russian 122 mm cannon
- The D-25S cannon is more than enough to completely destroy almost anything its shells connect with
- Quicker and more agile than the ISU-122
- Smaller target than the ISU-122
- Very poor gun depression of -2°
- Obsolete armor thickness, can easily be penetrated
- Costly to acquire (6,090 GE)
- Reload time is still more than twice as long as its usual opposition
There had been delays in the production of the SU-100 in autumn 1944, and so a new design was offered in the meantime. Uralmash's Design Bureau offered a tank destroyer on the same SU-100 hull, but with a 122 mm D-25S anti-tank gun. The 122 mm gun could be fitted without modification due to the commonality of the gun mounts.
Trials of the new tank destroyer, called the SU-122P, began in October 1944. Afterwards, it was sent to Government trials, passing all of them. It was recommended for service, but it never entered production, partially because of the long reload time of the 122 mm gun.
A new SPG, designated SU-122P, was designed in the spring of 1944. Its designers attempted to fit the previously developed SU-100 SPG with a powerful 122 mm D-25S cannon with the aim of increasing the SPG's firepower. Outwardly, this SPG differed from the SU-100 in that its barrel was longer and had a muzzle brake.
In September 1944, the SU-122P SPG underwent factory testing, which it passed successfully. In spite of this, the order to put it into mass production did not follow. There were several reasons for this decision. First of all, the 122 mm D-25S cannon's penetration was lower than that of the D-10S by 4-5 mm, and its ammunition capacity was reduced to 26.
Due to its separate loading, its rate of fire was reduced to 3-4 shots per minute, and the weapon's recoil was higher than that of the SU-100's, which negatively affected the undercarriage's durability. The previous issues of inadequate space in the fighting compartment had remained unsolved. In addition, SPGs with a similar cannon had already been designed based on the IS-2, which had a more suitable chassis, hull and cabin for heavy artillery weapons.
Only 1 experimental SU-122P SPG was produced.
