General info

The ISU-152 in the garage.

The ISU-152 is a Rank IV Soviet tank destroyer with a battle rating of 6.0 (AB) and 5.3 (RB/SB). It was introduced in during the Closed Beta Test for Ground Forces before Update 1.41. Wielding the same infamous 152 mm gun as on the KV-2 and SU-152, the ISU-152 presents better armour, mobility, and firepower with the addition of the heavy-hitting HEAT round for the gun.

Modules and improvements

History of creation and combat usage

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 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 the 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 stowage. The large ammunition pieces were limited to about 20 rounds in the vehicle, and each rounds were 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 heavy weight.

Combat usage

The ISU-152 was issued in a similar manner to the SU-152 in independent Heavy Self-propelled Artillery Regiments. Each regiments, of which 53 were formed from May 1943 to 1945, had 21 guns divided into four batteries of five vehicles and a commander vehicle. These regiments were supported by other military units to be flexible against threats. In December 1944, the Guards Heavy Self-propelled Artillery Brigades were formed to provide heavy fire support. These brigades had up to 65 vehicles, which would consist of ISU-152s or ISU-122s.

Like its predecessor the SU-152, the ISU-152 also served as a multi-role vehicle as a heavy assault gun, tank destroyer, and self-propelled artillery. As an assault gun, the vehicle was valuable during the Soviet's offensive operations assaulting fortified cities held by the Axis forces. The 152 mm gun was very successful in demolishing fortifications and strong points. The greater armour protection on the ISU-152 compared to the SU-152 (90 mm vs. 65 mm) made the vehicle very durable against German anti-tank weapons, even forcing the Tiger to come withing close range to penetrate the vehicle. Usual tactics of the ISU-152s in urban combat was to act in one or two vehicle groups with infantry to deter infantry anti-tank weaponry like the Panzerfaust. As a tank destroyer, the ISU-152 worked its unintended role well enough that it inherited the nickname Zveroboy ("Beast Killer") from the SU-152s. The ISU-152 was very capable of destroying many of the more armoured German tanks like the Panthers, Tiger Is, and Tiger IIs. Though not as rapid-firing or as accurate as dedicated anti-tank guns, the rounds of the 152 mm howitzer could blow the turret off a Tiger tank, and a direct hit would definitely caused extensive internal damages to the tank's internal mechanisms or kill the crew due to spalling of the hull due to the explosive force. The tank destroyer role was phased out with the introduction of dedicated vehicles like the SU-100. As a self-propelled artillery piece, the ISU-152 is able to successfully fire in indirect bombardments against enemy targets up to 7,000 meters away. Though it was not really a specialized vehicle for the role, it was better than typical towed artillery pieces due to being able to move and being an enclosed vehicle to protect the crew. The ISU-152 served in all these roles in all of the Soviet offensive operations into German territory all the way until the Battle of Berlin.

Many ISU-152s were exported by the Soviets after World War II to assist its allies and other Warsaw Pact members. Countries that had access to the ISU-152 in their military were Finland, Poland, China, Czechoslovakia, North Korea, Egypt, Iraq, Yugoslavia, and Romania. All of which used the ISU-152s up until the 1970s at latest.
