ISU-152 was a Soviet multirole fully enclosed and armored assault gun or armored self-propelled gun, also capable of serving as a heavy tank destroyer developed and used during World War II, with a subsequent use, mainly in the Soviet military, until the 1970s.

History

The ISU-152 marks its beginning on January 24, 1943. This was the moment of appearance of the first fighting vehicle of this family. It was designated Object 236 (Объект 236), using the same concept as the SU-152. The Object 236 was completed in Factory No. 100 in Chelyabinsk, and on the same day, January 24, underwent trials on the Chebarkulski artillery range, 107 km from Chelyabinsk. By February 7, 1943 the trials were over, passed with success. On February 14 the vehicle was adopted and put on production under the KV-14 (КВ-14) designation. In April 1943 was ordered KV-14 to be henceforth designated SU-152 (СУ-152). In time, the combat performance of SU-152, based on the KV-1S tank, made necessary the modernisation of the vehicle, using the new IS tank as a base. On May 25, 1943, shortly after deployment, the administration of Factory No. 100 ordered the beginning of the SU-152 modernization, which included an increase of the armour protection and other improvements. The development began in July 1943, under the supervision of Joseph Yakovlevich Kotin (the chief designer of Soviet heavy tanks) and G. N. Moskvin as the main designer, and in about a month the first modernized variant was ready. It was designated IS-152 (ИС-152). It underwent factory trials in September 1943, revealing a large number of different deficiencies, which sent it back for further improvement. In October 1943 a second (different) modernized variant was ready, designated Object 241 (Объект 241). It was an improvement over the IS-152. The factory trials began the same month, followed by state trials on the Gorohovetskom test range. On November 6, 1943, an order was issued for adoption of this variant, under the ISU-152 (ИСУ-152) designation, and in December its production began at the Chelyabinsk Kirovsk Plant, replacing the SU-152.^[1][2]

Design

On April 15, 1942 at the plenum of the artillery committee, where it was suggested the development of assault guns for support of the infantry, was acknowledged the necessity of also developing assault guns capable of destroying fortified positions. It was intended these assault guns to be armed with a 152.4 mm gun-howitzer and used for penetration of the enemy defence in the offensive operations planned for 1942-1943. This resulted in the development of the Object 236, and eventually the SU-152, which concept was later continued and further developed with the ISU-152.

The ISU-152 followed the same design as other Soviet self-propelled guns, except the SU-76. The fully armoured hull was divided into two compartments: fighting compartment for the crew, gun and ammunition in the front of the hull, and engine and transmission in the rear. The gun was mounted slightly to the right of centre with a limited traverse of 12 degrees left and right. The crew consisted of 4 or 5 men placed in the superstructure. Three of the crew were to the left of the gun: driver to the front, then gunner and last the loader. The vehicle commander and lockman were to the right: commander to the front and the lockman behind. When the crew consisted of 4 men, the loading was carried out by the lockman.

The suspension consisted of twelve torsion bars for the six road wheels on either side. The drive sprockets were at the back, and the front idlers were identical to the road wheels. Each track was made up of 90 links. There were three internal fuel tanks, two in the crew area and one in the engine compartment. These were usually supplemented with four unconnected external fuel tanks. Twelve and 24-volt electrical power supplies came from a 1 kW generator feeding four accumulator batteries.

For observation from the interior, all roof hatches had periscopes and there were two gun sights : telescopic ST-10 (СТ-10) and panoramic. For crew communication a TPU-4-BisF intercom was fitted, and for inter-vehicle communication there was a single 10R or 10RK radio. These were better than Soviet equipment at the start of the war but still inferior to German equipment.

The crew were given two PPSh submachine guns with 1491 rounds and 20 F-1 grenades for short range self-defence.

The ISU-152 was armed with the same gun as the SU-152. It used the hull of the IS-1 tank instead of the KV-1S. Later in the war the ISU-152 was further improved. It used the hull of the IS-2 or IS-2 model 1944 tank, the armour of the mantlet was increased, the gun was replaced by newer variants, a 12.7 x 108 mm DShK anti-aircraft machine gun was installed by the right forward hatch and later its ammunition capacity increased, the 10R radio set was upgraded to a 10RK and the fuel capacity was increased.

Some ISU-152s were equipped with even larger external fuel tanks, two tanks on the rear hull deck, in addition to the four external fuel tanks (90 litres each, maximum), or with two smaller additional external fuel tanks, on the hull rear. This option was probably available for the post-war ISU-152 variants.

Between December 1943 and May 1945, 1,885 ISU-152s were built. Mass production ceased in 1947, with 3,242 vehicles produced in total.

Post-war ISU-152 modernisation included installation of night vision sights, replacing of the V-2IS engine with the V-54K, the 12.7 machine gun was replaced by a newer variant, the ammunition capacity increased to 30 rounds, additional armor, automotive improvements and significant increase of the main fuel capacity.^[3][4]

Variants

The initial variant, developed in 1943. The factory designation was Object 241 (Объект 241). It was armed with the 152.4 mm ML-20S (МЛ-20С) gun-howitzer, with a barrel length of over 4.2 metres (27.9 calibers). The self-propelled gun carried 21 rounds of two piece (shell and charge) armour-piercing and high explosive ammunition. The gun had a maximum range of 6,200 metres. The armour-piercing round, weighing 48.78 kg, had a muzzle velocity of 600 m/s and a maximum penetration of 125 mm of RHA at 90° at a range of 500 metres. The ISU-152 had different modifications concerning the gun (newer modifications), the number of the hatches, or the hull, based on the one of IS-1, IS-2 or IS-2 model 1944. The latter modification had a thicker gun shield, fuel tankage with increased volume etc. Till May 1944 the main armament was the 152.4 mm ML-20 model 1937 gun-howizer. ISU-152 had a rate of fire of 2-3 rounds/min. The early modifications had three hatches at the superstructure roof and one emergency hatch at the bottom of the hull behind the driver's seat, which had an armoured cover. Later was added a fourth, round hatch, at the superstructure roof on the right, next to the rectangular hatch on the left. The later ISU-152 modifications, with newer gun and slightly longer barrel, up to over 4.9 metres (32.3 calibers), had a maximum range of fire of up to 13,000 metres.

ISU-152-2

One prototype, developed in 1944. In April 1944, in attempt to increase the firepower of ISU-152, a high-power variant of the self-propelled gun was developed in Factory No. 100, designated ISU-152BM (ИСУ-152БМ), sometimes referred to as ISU-152BM-1 or ISU-152-1. The factory designation was Object 246 (Объект 246). The "BM" ("БМ") in the designation stands for "High Powered" ("Большой Мощности"). The main purpose of the ISU-152BM was the fight against heavily armoured tank destroyers such as the Elefant and the Jagdtiger. It was armed with the 152.4 mm BL-8 (БЛ-8) long barrel gun, which unlike the ISU-152's gun wasn't a gun-howitzer. The gun had a maximum range of 18,500 metres, with the 43.56 kg high-explosive shell which had a muzzle velocity of 880 m/s. The overall length of the gun was over 8 metres, with a barrel length of 7620 mm (50 calibers). The armour-piercing round, weighing 48.78 kg, had a muzzle velocity of 850 m/s. During test firing at armour plates with different thickness, the ISU-152BM have successfully penetrated a maximum of 203 mm of RHA at 90° at ranges of up to 2000 metres. However, during the trials, July 1944, the gun showed some deficiencies such as being difficult to operate by the crew, unreliable work of the muzzle brake and the breech block, and unsatisfactory performance of the shells. In addition, the gun, protruding far forward of the hull front, was limiting the maneuverability of the fighting vehicle. The self-propelled gun carried 21 rounds of two piece (shell and charge) ammunition, and had a rate of fire of 2 rounds/min. It used the engine, transmission, running gear and electric equipment of the ISU-122. In August 1944 the BL-8 gun was replaced with the improved 152.4 mm BL-10 (БЛ-10) long barrel gun, with a slightly shorter barrel of 7392 mm (48.5 calibers). The self-propelled gun was designated ISU-152-2 (ИСУ-152-2). The factory designation was Object 247 (Объект 247). The fighting vehicle was also equipped with external fuel tanks. The gun had a modified muzzle brake and a semi-automatic breech block. It had a rate of fire of 3 rounds/min. The BL-10 had a maximum range of 18,000 metres, with the 43.56 kg high-explosive shell. In December 1944 the ISU-152-2 underwent trials, revealing the barrel strength and the angle of horizontal guidance were unsatisfactory. The gun was sent for further improvement, but it wasn't completed before the war ended. The fighting vehicle was never adopted. After the war, the final and most improved, third modification of ISU-152-2 was completed. The gun had a maximum range of 19,500 metres, using a 48.5 kg high-explosive shell with a muzzle velocity of 880 m/s.

Object 704

One prototype, developed in 1945. It used elements of the IS-2 and IS-3 tanks. The overall height of the vehicle was reduced to 2240 mm, which was compensated with an increased width of the superstructure. The factory designation was Object 704 (Объект 704). It was armed with the 152.4 mm ML-20SM model 1944 (МЛ-20СМ обр. 1944 г.) gun-howitzer, with a barrel length of over 4.5 metres (29.6 calibers) and no muzzle brake. It had a maximum range of 13,000 metres. The self-propelled gun carried 20 rounds of two piece (shell and charge) armour-piercing and high explosive ammunition. The armour-piercing round, weighing 48.78 kg, had a muzzle velocity of 655 m/s. The rate of fire was 1-2 round/min. Object 704 had four hatches at the superstructure roof and one emergency hatch at the bottom of the hull behind the driver's seat, which had an armoured cover. The self-propelled gun carried two external fuel tanks (90 litres each), not connected to the supply system. The secondary armament of the fighting vehicle consisted of two 12.7 x 108 mm DShK machine guns, one anti-aircraft and one co-axial. The protection was increased by placing thicker armour at more radical angles. In the area of the gun, where the mantlet combined with the hull front behind it and the housing of the recoil mechanism, the armour thickness was 320 mm. Object 704 (ИСУ-152 обр. 1945 г.) was the best protected of all experimental or production Soviet self-propelled guns of the Second World War. However, the radical incline of the superstructure walls combined with the increased recoil of the gun, due to the lack of a muzzle brake, significantly complicated the work of the crew, and for this reason mainly wasn't adopted.^[5][6]

ISU-152K

A modernised variant of the wartime ISU-152 was developed in 1956. It used a new engine, that of the T-54, with a cooling system and a heater. The capacity of the main internal fuel tank was increased to 920 litres, which added 500 km more to the vehicle range on a road. The ammunition capacity was increased to 30 rounds after the removal of an additional internal fuel tank placed in the crew compartment. The gun had a maximum range of 13,000 metres. It received a new commander's cupola, and also new sights. The factory designation was Object 241K (Объект 241К). The running gear used many elements of the T-10. The mantlet had additional armor ring protecting the sight. Some of the ISU-152Ks received an additional 15 mm armour plate welded on top of the 60 mm armour plate covering the mantlet above. Also, some of them received an additional armour plate welded on the upper mantlet front. The modernisation was carried out in the Leningrad Kirov Plant.^[2]

ISU-152M

The final variant, a modernised former ISU-152, was developed in 1959. The work was now transferred to the Chelyabinsk Kirovsk Plant. This modernisation was parallel to the IS-2M program and the ISU-152M used many elements of the tank. The factory designation was Object 241M (Объект 241М). The innovations included the installing of night vision sights, increased ammunition stowage for the 12.7 mm machine gun, which was replaced by the improved DShKM, and internal automotive improvements. It had the same new commander's cupola and sights as the ISU-152K. It also had the same main internal fuel tank capacity, 920 litres, adding 500 km more to the vehicle range on a road compared to the ISU-152, and an increased ammunition capacity to 30 rounds due to the removal of an additional internal fuel tank. The gun had a maximum range of 13,000 metres. The ring protecting the sight was present, and the armour of the upper mantlet front was further increased with a thicker additional armour plate. The ISU-152M had the same V-54K engine with a heater, but lacked the cooling system.^[7]

Multirole use

The ISU-152 self-propelled gun combined three battle roles : heavy assault gun, heavy tank destroyer and heavy self-propelled artillery. The 152.4 mm gun used a number of powerful (shell and charge) ammunition. Some of these ammunition had a 43.56 kg high-explosive shell, or a 48.78 kg armour-piercing shell, or the heaviest of all, the 53-G-545 (53-Г-545) long range concrete-piercing ammunition with a 56 kg shell. The ISU-152 was used for infantry and tank support, and attack on fortified positions in a direct fire role, for support on the battlefield in an indirect fire role, and for fight against tanks with a direct fire.

Heavy assault gun

As a heavy assault gun, the ISU-152 was an extremely valuable weapon in urban combat operations such as the assaults on Berlin, Budapest and Königsberg. The vehicle's excellent armour protection finally provided the 152.4 mm platform with good protection from most German anti-tank guns, allowing it to advance into the face of direct anti-tank fire, while the huge low velocity high-explosive rounds were excellent at blasting open even the most heavily fortified and reinforced enemy strongpoints. Such actions would be much more dangerous and much less effective for a conventional towed artillery piece, with their high crew exposure and low mobility, or even a tank, with their smaller main guns. When supporting tanks, the usual tactics of the ISU-152 were to be used in the second line of the attack order, 100 to 200 metres behind the attacking tanks, which were usually IS tanks with equal mobility.

The ISU-152, like the earlier SU-152 and contemporary ISU-122, was employed by Independent Heavy Self-propelled Artillery Regiments. Between May 1943 and 1945, 53 of these regiments were formed. Many of them were re-formed tank regiments, and employed similar direct fire tactics as used by tanks when supporting infantry. Each of the heavy regiment had 21 guns, divided into 4 artillery batteries of 5 vehicles and the commander's vehicle. For support the heavy regiments had some supplementary unarmoured vehicles such as trucks, jeeps, or motorcycles. In December 1944, Guards Heavy Self-propelled Artillery Brigades were formed, to provide heavy fire support to the tank armies. They were organized along the model of tank brigades, each with 65 ISU-152 or ISU-122 self-propelled guns.

To minimize the risks of being knocked out by Panzerfaust-equipped units during urban operations, the ISU-152 usually acted in one or two vehicle detachments alongside infantry squads for protection. The infantry squad would include a specialist sniper (or at least a sharpshooter), some submachine gunners and sometimes a flamethrower. The ISU-152's heavy calibre DShK machinegun was also useful for targeting Panzerfaust gunners hiding on upper floors of city buildings or behind protective cover, barricades, etc. Effective teamwork between the ISU-152 crew and supporting infantry allowed them to achieve their goals with minimal losses, but if such tactics were not adhered to, the attacking vehicles were easily attacked and destroyed, usually through the weaker armor on the roof or rear compartment.

Heavy tank destroyer

The ISU-152 could also operate as an effective heavy tank destroyer. Though it was not designed for the role, the vehicle inherited the nickname Zveroboy ("beast killer") from its predecessor, the SU-152, for its rare ability to reliably kill the best protected German fighting vehicles; the Panther tank, the Tiger and King Tiger tanks, and even the rarely fielded Elefant and Jagdtiger tank destroyers. The sheer weight of the 152.4 mm shells resulted in an extremely low rate of fire, only one to three rounds per minute, and were not as accurate at long range as high-velocity tank antitank guns. However, the massive blast effect from the heavy high-explosive warhead was capable of blowing the turret completely off a Tiger tank. A direct hit usually destroyed or damaged the target's tracks and suspension, immobilizing it. While the low-velocity 152mm shell did not generally penetrate heavy armor, it frequently killed or severely wounded the crew through spalling (splintering) inside the hull as well as injuries caused by blast concussion. Surviving crew were often left with an immobilized vehicle which had to be hurriedly abandoned before being destroyed. For anti-tank operations following the Battle of Kursk, armour-piercing ammunition was developed, with an eye towards giving the howitzer a more traditional anti-tank capability. However, these rounds were expensive, in short supply, and only moderately more effective than the standard non-penetrating high-explosive round. As a howitzer the ML-20S exchanged velocity and accuracy for throw weight and distance, and was not intended to compete with true anti-tank guns. Sometimes the concrete-piercing ammunition was used for the anti-tank role. A primitive shaped charge ammunition, with a 27.44 kg shell, was also developed. It had a maximum penetration of 250 mm of RHA at 90°, but it was not used during the war.

The ISU-152's 90 mm of sloped frontal armor, in contrast to the SU-152's 65 mm, provided excellent frontal protection from the 75mm KwK 40 gun of the ubiquitous Panzer IV and StuG family at all but the closest ranges, while also forcing the original Tiger I, with its vaunted 88mm KwK 36 gun, to close to medium ranges in order to successfully penetrate the vehicle, negating its traditional long range superiority and exposing more of its vulnerable flanks to the 85mm ZiS-S gun of the Soviet T-34-85.

The ISU-152 was not a true purpose-built tank destroyer. It had a very low rate of fire compared with specialised tank destroyers such as the German Jagdpanther or the Soviet SU-100, which could manage a brief burst of 5-8 rounds per minute. However, prior to the introduction of the SU-100 it was the only Soviet armored vehicle capable of tackling the German heavy tanks with any kind of reliability, and its ability to satisfy multiple roles meant it was produced in far greater numbers than the SU-100. Attention to camouflage, quick relocation between firing positions, and massed ambushes of 4-5 vehicles firing in salvo at a single target's flanks reduced the disadvantage of the low rate of fire. Using these tactics, the ISU-152 became greatly feared by German heavy tank commanders, robbing them of their prior sense of invulnerability to Soviet guns and forcing them to commit their forces more cautiously and sparingly.

Heavy self-propelled artillery

The ISU-152 was also sometimes used as a self-propelled artillery for support on the battlefield and preparatory bombardments, though it had a medium range of fire and a slow speed of reloading. The Soviet army had not developed specialized vehicles for this purpose. Their tank and mechanized units were well equipped with towed artillery, but the towed guns were very vulnerable while moving and they could not support tanks and motorized infantry during rapid advances into enemy positions, especially when they lack the armored fully enclosed design of the fighting vehicles like ISU-152.

Despite the ISU-152's good features it suffered in some other areas. The greatest disadvantage was that the internal stowage was limited to only 20 or 21 rounds of ammunition, with extra rounds often stowed on the rear deck. Replenishing the vehicle's ammunition supply took over 40 minutes and required a very strong loader, due to the large size and weight of the shells (the shells weighed over 40 kg). The ST-10 telescopic sight used for direct fire was graduated up to 900 metres. A second, panoramic, sight was used for direct fire up to 3,500 meter range (7000^[8] no direct fire). However, it was problematic for the gunner to switch between the two visors. To compensate it was simpler to concentrate the fire of several vehicles onto the target, sacrificing accuracy for sheer volume of firepower. The high-explosive shells were large enough to take out even a heavily armoured vehicle, or a fortification with the even heavier long range concrete-piercing shells. The usual complement of ammunition was 13 high-explosive and 7 armour-piercing or concrete-piercing.

Foreign use

Finnish military

In June 1944, during the Continuation War, a captured ISU-152 was used by the Finnish military. It was lost in the fighting. Another one was repaired in Varkaus, Finland, but never saw action.

Polish military

In 1944 over 30 ISU-152s were delivered to the People's Army of Poland. Shortly after, the Poles formed the 25th Polish self-propelled artillery regiment, consisting of 10 ISU-152s and 22 ISU-122s. As part of the 1st Polish tank corps (T-34 and T-34-85 tanks), the regiment took part in the fights on the river Nysa, southwest of Poland in March 1945. In the early 1945 the Polish command began to form another ISU-152 regiment, but with not enough of these fighting vehicles, the newly formed 13th Polish self-propelled artillery regiment received two ISU-152 and two SU-85 artillery batteries. This regiment took part in the Battle of Berlin in April–May 1945.

During the post-war period the ISU-152s remained in the Polish military till the early 1960s.

Chinese military

In 1955 the Soviet Armed Forces retreated from Dalian, China ending 10 years residence. All armament was sold to the People's Liberation Army, including 67 ISU-152s, 45 of which were given the new founding 1st Mechanical Division.

Czechoslovakian military

As part of the military help to the friendly countries, a few ISU-152s were transferred to the Czechoslovakian military after the World War II, where they were used till the late 1950s.

North Korean military

During & after the Korean War, ISU-152s were used by the North Korean military.

Egyptian military

In the early 1960s the Egyptian military received at least one regiment of ISU-152s. They were used during the 1967-1973 Egyptian–Israeli Wars.^[2]

Iraqi Military

A few surviving examples were operational during the Iran-Iraq war and First Gulf War, which were used as mobile artillery by the Iraqi army

Yugoslav military

The Yugoslav Army had only one ISU-152 in its inventory which was abandoned by units of the Soviet Red Army 2nd Ukrainian Front in 1944 when it became stuck in the mud some 2 km from Pančevo bridge. In 1946 members of the Yugoslav 2nd Tank Brigade's 1st battalion, led by technical officer Stojimir Ilijevic – Guerrilla, recovered the self-propelled gun after five days of work. As a unique vehicle it was used by the Tank School at Bela Crkva (which relocated to Banja Luka in 1948). In 1954 the standard engine was replaced by an engine from a Soviet T-34 tank.
