General info

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

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:

• 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

Cons:

• 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

History

In-game description

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.
