Usage in battles

The ISU-152 is a tank destroyer with a huge 152 mm cannon which can one-shot any target that it penetrates. In an uptier, the gun is equipped with a HEAT shell that has enough penetration to destroy even the most armoured heavy tanks. However, the gun comes with its drawbacks. Its reload time is long, shell velocity is low, and on top of that, shell drop must be accounted for when aiming. This makes aiming and leading at long ranges difficult--indeed, the ISU-152 is best at close and medium ranges.

The gun has a very small gun depression, which means that the ISU-152 is unsuited for hilly maps and for firing from behind ridgelines. Flat, urban terrain lets this vehicle use its gun to the greatest potential.

Of course, the ISU-152 is not a turreted vehicle, and this means that flankers such as the M18 Hellcat are extremely dangerous. Worse, the ISU-152 is quite sluggish in the mobility department. Repositioning in order to face an enemy takes a considerable amount of time, which means that it's necessary to keep a careful eye out for flankers, and to plan escape routes in dangerous situations.

As for armour, the ISU-152's protection is average. Its roof armour can protect against aircraft machine guns and some 20 mm cannons, and its side armour protects well against SPAA guns. However, the frontal armour is easily penetrated by many of the guns at this tier. And, the tightly-packed arrangement of the crew inside the vehicle means that being one-shot is not a rare occurrence in this vehicle.

Provided you have the HEAT shell unlocked, the ISU-152 is a exceptional machine to use in a full uptier and even beyond, with up to 250mm of armour penetration. The HEAT shell on the ISU-152 is identical to the one on the Object 268, a BR 7.3 tank destroyer, with the same armour penetration stats to boot. With the extra silver lions obtainable from the "Rank does not matter" achievement, the ISU-152 may actually be more effective in a uptier then at tier.

Pros and cons

Pros:

• Deadly cannon provides superior one-shot capacity with any target upon penetration
• Powerful HEAT penetrates up to 250mm which is very effective in a full uptier. For example the early Centurions, Ferdinand, Tiger II H can all get penetrated with ease.
• The huge gun mantlet and its complex armor layout is capable of deflecting quite some shells sometimes.
• 30mm roof armor resists popular aircraft weapons well, like the 12.7mm M2 with ground target belt and the MG 151.
• All-round protection provides good resistance against flanking SPAAs. The M19 / M42 are very common flankers.

Cons:

• Long reload of more than 20 seconds and the rather curved trajectory demands very precise aiming, which isn't beginner friendly.
• Front armour is only 75mm and is not well angled. Gets penetrated easily by common guns at the BR, like the 76mm M1, 17 pdr, 75mm and 88mm.
• Closely packed crew all easily get killed when an explosive shell penetrates.
• Very inadequate gun depression of -3° combined with the sluggish mobility makes it only capable of fighting in urban (flat) areas, but never the hills.
• Turretless layout and the sluggish mobility makes it very vulnerable to surprise flankers, for example the infamous M18, T20, T25 and Puma.
• Gun breech often gets damaged while under enemy fire.

History

Development

Development of the ISU-152 already started alongside the SU-152, its predecessor. The SU-152 was based off the KV-1S tank, which itself is a lighter version of the KV-1 heavy tank. The vehicle, while highly praised in its performance, saw a need for modernization with the KV-1's phasing out of the Soviet's inventory and being replaced with the new IS heavy tanks. The modernization process began on May 25, 1943, with the goal of using the IS tank as the basis of the vehicle and also increasing armour protection alongside other improvements. Development began in July under Joseph Yakovlevich Kotin, a chief designer of Soviet heavy tanks, who worked alongside G. N. Moskvin as the main designer. The designing of the improved vehicle went on for a month before the first variant was ready, designated the IS-152. This was tested in September 1943, which revealed defects and deficiencies with the design, so it was redone into a second variant called Object 241 in October 1943. Trials began on Object 241, which was successful through the factory and state trials and adopted on November 6, 1943, as the ISU-152. Production began in December at the Chelyabinsk Kirovsk Plant, producing 3,242 units from then all the way until 1947, with 1,885 units made by the end of World War II.

Design

The ISU-152 was the successor to the SU-152, retaining the same 152 mm ML-20S howitzer needed to destroy enemy fortifications in offensive operations. The vehicle was run on a torsion-bar suspension system from the IS tank chassis. The crew consists of four or five men in the vehicle, the optional crew member being a loader. The crew had external views through periscopes and two gun sights, a panoramic and a telescopic one. Crew communication was possible with an intercom system and a 10R or 10RK radio was available to communicate between vehicles. The crew had access to two PPSh submachine guns and grenades in the tank to defend themselves against infantry.

A drawback to the vehicle's design was the gun ammunition and internal storage. The large ammunition pieces were limited to about 20 rounds in the vehicle, and each round was extremely heavy and large that reloading the tank can take up to 40 minutes and lots of strength. Rate of fire was also reduced by the ammunition's heavyweight.
