| This page is about the tank destroyer ISU-122S. For the version equipped with an A-19 cannon, see ISU-122. |
Description
The ISU-122S is a rank IV Russian tank destroyer
with a battle rating of 5.7 (AB/RB/SB). It was introduced during the Closed Beta Test for Ground Forces before Update 1.41. Compared to the ISU-122, the ISU-122S presents a better 122 mm cannon by allowing for faster reloads.
General info
Survivability and armour
Armour type:
- Rolled homogeneous armour
- Cast homogeneous armour (Gun mantlet)
| Armour | Front | Sides | Rear | Roof |
|---|---|---|---|---|
| Hull | 60 mm (75°) Front glacis 90 mm (31°) Lower glacis |
90 mm | 60 mm (50°) Top 60 mm (39°) Bottom |
30 mm |
| Superstructure | 90 mm (30°) Front glacis 100 + 65 mm (7-35°) Gun mantlet |
75 mm (14-15°) | 60 mm | 30 mm |
Notes:
- Suspension wheels are 20 mm thick while tracks are 30 mm thick.
- There is a plate of 40 mm thick under the gun mantlet, reinforcing the original 65 mm gun mantlet case.
Mobility
Write about the mobility of the ground vehicle. Estimate the specific power and manoeuvrability, as well as the maximum speed forwards and backwards.
Armaments
Main armament
Give the reader information about the characteristics of the main gun. Assess its effectiveness in a battle based on the reloading speed, ballistics and the power of shells. Do not forget about the flexibility of the fire, that is how quickly the cannon can be aimed at the target, open fire on it and aim at another enemy. Add a link to the main article on the gun: {{main|Name of the weapon}}. Describe in general terms the ammunition available for the main gun. Give advice on how to use them and how to fill the ammunition storage.
Additional armament
Some tanks are armed with several guns in one or more turrets. Evaluate the additional weaponry and give advice on its use. Describe the ammunition available for additional weaponry. Give advice on about how to use them and how to fill the ammunition storage. If there is no additional weaponry remove this subsection.
Machine guns
Offensive and anti-aircraft machine guns not only allow you to fight some aircraft but also are effective against lightly armoured vehicles. Evaluate machine guns and give recommendations on its use.
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:
- Good gun with excellent damage potential and penetration
- Fast reverse speed, can reach 10MPH in reverse
- Surprisingly capable of bouncing and stopping some shells
- Transmission in rear
Cons:
- Terrible tank traverse and casemate style make getting flanked a death sentence
- Long reloads
- Poor mobility
- Abysmal gun depression
History
Development
When the ISU-152 began production in 1943 with the large 152 mm ML-20S gun, production of the chassis and hull soon exceeded the supply of the ML-20S gun, which caused a decrease in production of self-propelled guns for the Soviet military. It was determined to speed up self-propelled gun production, the ISU chassis were to be mounted with the 122 mm A-19S gun. Work on this mounting already began before the supply issue in December 1943 at the Chelyabinsk Kirov Plant (ChKZ), which had a design team simply take the ISU-152 chassis and hull and only changing out the armament with the 122 mm gun, but this prototype - Object 242 - was not immediately put into production despite successful testings. When the supply issue arose, the prototype was then adopted by the Soviet Defense Committee for increased production and also that the 122 mm gun had better accuracy against tanks than the 152 mm gun. The ISU armed with the 122 mm gun, designated the ISU-122, began production in April 1944.
Upgrade
The original ISU-122 is equipped with the 122 mm A-19S gun, which had a firing rate of 1.5 to 2.5 shots per minute due to its manual-piston breech. An attempt to fix this was a modernized A-19 gun called the D-25. The D-25 didn't see installment onto the ISU-122 for a while due to prioritization on the IS-2 tanks, but it was available for use on self-propelled mounts after September 1944 as the D-25S. The ISU-122 prototype mounting the D-25 gun was called Object 249 which was successfully tested and an improvement over the A-19 gun with an increased firing rate of 2 to 3 shots per minute with one loader and up to 4 shots per minute with an additional loader in the crew. The D-25 also exploited the use of a muzzle brake in order to reduce the recoil forces on the gun, so the recoil buffer on the D-25 was much smaller than the A-19, which helped reduce the size of the gun and improved crew work space in the self-propelled gun. Object 249 was then adopted as the ISU-122S, which entered production side by side with the ISU-122 u and both were produced up until the end of 1945. ChKZ produced both vehicles during the war and manufactured 1,735 ISU-122s (April 1944 - December 1945) and 675 ISU-122Ss (September 1944 - December 1945).
Combat usage
The ISU-122 were organized in units in a similar fashion as the ISU-152. Focus were made to not mix the two vehicles in the same regiments or brigades due to logistical reasons with ammunition and ballistic differences in indirect fire, but some units were equipped with both vehicles anyways. Like the ISU-152, the ISU-122 proved to be a very powerful multi-purpose vehicle as an assault gun, self-propelled artillery, and tank destroyer. The 122 mm gun on the ISU-122 allowed it to engage armour and fortifications with heavy armour-piercing round and a large high-explosive round. The primary role of the ISU-122 was as a tank destroyer due to the gun's superior ballistics compared to the ISU-152's, which large caliber size more suited its role as an assault gun. The ISU-122 did participate as an assault gun role in urban combat to support the infantry, but the lack of rotating turret, and long barrel length restricted its maneuvering and ability to engage all enemies in a large angle. Nevertheless, commanders found the ISU-122 as a very good assault gun. Usage of the ISU-122 in an indirect firing role as a howitzer is rare, but when used could fire up to 14 kilometers away. Usage as an artillery piece is more likely during a rapid offensive where towed artillery behind the lines are unable to keep up with the advancing infantry lines.
