TheZSU-57-2 Ob'yekt 500is aSovietself-propelled anti-aircraft gun(SPAAG), armed with two 57 mmautocannons.'ZSU' stands forZenitnaya Samokhodnaya Ustanovka(Russian:Зенитная Самоходная Установка), meaning "anti-aircraft self-propelled mount", '57' stands for theboreof the armament in millimetres and '2' stands for the number ofgun barrels.It was the first Soviet mass-producedtrackedSPAAG. In the USSR, it had the unofficial nicknameSparka(Russian:Спарка), meaning "twin mount," referring to the twinautocannonwith which the vehicle is armed.[10]
Development history
[edit]Origins
[edit]During World War II,ground-attack aircraftemerged as a significant threat to mechanized units on the move. Conventional towedanti-aircraft artillery(AAA) was an inadequate response under such conditions owing to the time needed to bring anti-aircraftmachine gunsinto action. This experience made it clear that an anti-aircraft tracked vehicle, armed with small-boreautocannonsorheavy machine guns,was needed. Vehicles such as the GermanWirbelwindandspecialized variantsof the USM3 Half-trackhad been used to good effect in the final battles of World War II, both by the US and nations which had received the M3 throughLend-Lease.
In 1942, Soviet engineers developed the T-60-3. The vehicle, based on theT-60light tankchassis, was armed with two 12.7 mmDShKheavy machine guns; but the prototype did not go into production because of flaws in the design.[11][12]The SU-72 SPAAG and several other experimental vehicles based on the T-60 orT-70light tank chassis and armed with 37 mm autocannon were also tested in 1942–1943. TheZSU-37was based on the chassis of theSU-76Mself-propelled gun (SPG) and armed with a 37 mm 61K anti-aircraft autocannon in an open-top rotating armoured turret. The vehicle entered production in February 1945 and was in small-scale production until 1948.[13]
After World War II it became clear that the firepower of a single 37 mm AA gun was insufficient to destroy high-speed, low-altitude targets. SPAAGs based on light tank chassis had poor maneuverability in difficult terrain, slow off-road speed and insufficient range in comparison with medium tanks and SPGs. Thus the ZSU-37s were retired from service by the end of the 1940s.[citation needed]
ZSU-57-2 prototypes
[edit]For several years after World War II there were no new SPAAG models in the USSR except for theBTR-152A(which were armed with two or four14.5mmKPV heavy machine guns,designed ZTPU-4) and theBTR-40A(ZTPU-2) wheeled SPAAGs.[14]Two of the USSR's potential enemies – the United States and Great Britain, had high-quality air forces with substantialground-attackexperience. The need for a new tracked AA vehicle was apparent.
In February 1946, the Design Bureau of Works No. 174 inOmskand the Research Institute No. 58 inKaliningrad, Moscow Oblastsubmitted a joint project for a SPAAG based on theT-34tank chassis, to be armed with four 37 mm AA guns, to the Technical Council of the Ministry of Transport. However, the project did not proceed due to the desire to concentrate attention on the newest tank chassis available.[1]
The Design Bureau of Research Institute No. 58 (NII-58)[3](formerly known as the Central Artillery Design Bureau, TsAKB), under the supervision ofV.G. Grabin,began the development of a twin 57 mm S-68 automatic anti-aircraft gun based on the57mm S-60in the spring of 1947. The first S-68 prototype (with ESP-76diesel-electricdrive), was ready in 1948. It was initially mounted on a S-79A four-wheel carriage; that system passed various tests but did not go into production.[1]
The final project of the ZSU-57-2 (Ob'yekt 500), armed with twin S-68s and based on a light-weightT-54tank chassis, was finished in 1948. The first prototype ZSU-57-2 was built in June 1950, the second in December 1950. After official tests, taking place between 27 January and 15 March 1951 in which the vehicle was driven for 1,500 km (932 miles) and 2,000 rounds were fired from its guns, six more prototypes were built for service tests. These prototypes had some improvements included, such as an increased ammunition load (300 rounds), but development stopped again due to the absence of improved S-68A guns. Various updates continued in 1952 and 1953. The service tests, in which two vehicles participated, took place in December 1954. This was due to delays in the development of drives for the S-68 guns.[1]The ZSU-57-2 officially entered service in the Soviet Army on 14 February 1955.[3]
Description
[edit]Overview
[edit]Based on past experiences with SPAAG designs, Soviet engineers designed a vehicle that used a modifiedT-54chassis, with four twin road wheels per side instead of five, and much thinner armour. The vehicle was armed with twin 57 mm S-68 autocannon in a new, large, rotating, open-topped turret. The ZSU-57-2 consists of three compartments: driver's in the front, fighting in the middle and engine-transmission at the rear. The hull is more spacious in comparison with the T-54 because of the thinner armour and has different locations for some equipment. The general layout, with transverse mounting of the engine, is the same.[3][15]
Driver's compartment
[edit]The driver's compartment is located on the left hand side of the front of the hull. The driver's seat is moved forward and to the left in comparison with its location in the T-54.[1]The compartment is equipped with a single-piece hatch cover opening to the left and twoperiscopicvision devices. One of them can be replaced by the TVN-1infrared visiondevice which is operated together with theinfrared headlamp(active night vision), which is mounted on the right track board. A fire-fighting equipment signal panel and a spare parts case are also located in the driver's compartment.[15]
Turret
[edit]The open-topped box-type welded turret has aball-bearingrace ring 1850 mm in diameter. The turret rear can be removed, which makes replacement of the guns easier.[3][15]The turret can be covered in the travelling position by atarpaulinwhich has 16 plexiglass windows.[15]
To aim the guns, base data such as the target's speed, direction and range must be entered into thesighting systemby the sight adjuster, who sits to the left of the guns at the rear of the turret. The target's speed and direction is determined by visual estimation, while range can also be estimated visually or with therangefinder.The upper front of the turret has two small ports with armoured covers meant forcollimatorsof the sight.[15]
To fire the guns, thebreechesmust first be opened. The left and rightloaders,located in the forward part of the turret on both sides of the main armament, loadclipsinto themagazinesof their respective weapons. The loaders' travel seats should be stowed in clamps on the turret sides before opening fire. The gunner, seated on the left hand side in the middle of the turret, aims ( "lays" ) the gun and opens fire using an electric trigger, which fires both barrels, or two-foot pedals, which can fire either barrel independently. If manual mechanical backupgunlayingis used instead ofelectro-hydraulicdrive, three crew members instead of two should work with the sight. The commander, who sits on the right hand side in the middle of the turret, lays the gun in azimuth, the gunner in elevation and the sight adjuster enters data into the sight. The loaders feed clips into the twin autocannon manually as needed, similar to theBofors 40mm.[3][15]
Armament
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/4/48/ZSU-57-2-latrun-3.jpg/220px-ZSU-57-2-latrun-3.jpg)
The twin S-68s arerecoil-operatedand weigh 4,500 kg. Their construction was based on two57 mm S-60 AA autocannons.The guns have a recoil of between 325 and 370 mm. The individual weapons cannot be swapped from one side to the other as they are mirror images. Eachair-cooledgun barrel is 4365 mm long (76.6calibers) and is fitted with amuzzle brake.They can be elevated or depressed between −5° and +85° at a speed of between 0.3° and 20° per second, the turret can traverse 360° at a speed of between 0.2° and 36° per second. Drive is from adirect currentelectric motor and universal hydraulic speed gears (a manual mechanical drive is also provided in case of electrohydraulic failure; with the use of mechanical drive, elevation speed is 4.5° per second and the turret traverse speed is 4° per second).[3][15]
The guns firing together are capable of firing up to 210–240fragmentationandarmour-piercingtracer(AP-T)shellsper minute, with apractical rate of fireof between 100 and 140 rounds per minute, which gives a fire time of 2-3 minutes before running out of ammo.[3]Muzzle velocityis 1,000 m/s. Each clip has 4 rounds, each of which weighs 6.6 kg; the charge in each round consists of 1.2 kg of 11/7nitrocellulosepowder, a projectile weighs 2.8 kg. Maximum horizontal range is 12 km / 7 miles (with an effective range against ground targets of up to 4 km / 2.5 miles. Maximum vertical range is 8.8 km / 28,871ft with a maximum effective vertical range of 4.5 km / 14,750 ft). Fragmentation rounds have asafety-destructorwhich activates between 12 and 16 seconds after being fired to ensure the shells will not fall back to ground, so the maximum slant range of anti-aircraft fire is 6.5–7 km / 4-4.3 miles.[15]BR-281 armour-piercing rounds are able to penetrate 110 mm armour at 500 m or 70 mm armour at 2,000 m (at 90° impact angle).[15]
The S-68 autocannon was the most powerful AA gun installed on SPAAGs at that time.[16]According to the statistical data of the Air Defence Research Institute No. 2, a direct hit of a single 57 mm shell could destroy a contemporary jet aircraft. In order to shoot down a jet bomber of theCanberratype, an average of 1.7 hits were deemed necessary.[16]
The vehicle carries 300 rounds,[7][10]and the ammunition is stowed as follows: 176 rounds in clips inside the turret, 72 rounds in clips in the hull front, and 52 separate (unclipped) rounds in special compartments under the turret floor. Armour-piercing rounds in clips are placed in the rear part of the turret to the left and right of the guns. Empty shell cases and clips are removed via aconveyor beltthrough a special port in the turret rear into an external metal wire basket on the back of the turret.[15]
Armour protection
[edit]The ZSU-57-2'sarmourisweldedrolled steel[8]sufficient to protect the vehicle from7.62mmarmour-piercing bullets at 250 meters.[1][3]
Armour thickness is as follows:
- Hull front: (upper) – 13.5 mm; (lower) – 15 mm; at 60 degrees upper[3][17]
- Hull sides: (upper) – 15 mm; (lower) – 13.5 mm[3]
- Hull rear: 8 – 10.6 mm at 45 degrees[3]
- Hull roof: 15 mm[10]
- Hull bottom: 13.5 mm[3][10][17]
- Turret sides: 13.5 mm[3][10]
- Gun mantlet: 15 mm[17]
- Turret roof: open
Maneuverability
[edit]The ZSU-57-2 has a maximum road speed of 50 kilometres per hour(31 miles per hour), which is reduced to around 30 km/h off-road(19 mph).[3][6][7][8]The vehicle has better acceleration compared with the T-54 because of its betterpower-to-weight ratio(18.6 hp per tonne). It has an operational range of 420 km(261 miles) on roads and 320 km(199 miles) across country.[9][7][8]The vehicle can cross 0.8 m high vertical obstacles, 2.7 m widetrenches,ford1.4 m deep water obstacles and climb 30° gradients.[3][8][15]
The ZSU-57-2 uses the same engine as the T-54. It is awater-cooledV-544-strokedieselV12engine with adisplacementof 38.88 litres, which develops 520hp(388 kW) at 2,000 rpm. The engine itself weighs 895 kg. Fuel capacity is 830 litres carried in three fuel tanks inside the hull (640 L total) and two external fuel tanks on the right fender each of 95 L; fuel capacity was increased in comparison with the T-54. External rear-mounted supplemental fuel tanks can increase the road range to 595 km (370 miles).[3]
Themechanical transmissionin the rear part of the hull consists of a change gear quadrant, a primarymultiplate clutchunit with metallic friction pads, a manual gearbox with five forward gears, two multiplate planetary steering clutches with band brakes and two in-linefinal drivegroups.
The chassis has four twin rubber-tyred road wheels with individualtorsion bar suspension,a reardrive sprocketwith detachable sprocket rings (lantern-wheel gear) and anidler wheelon each side. The first and last road wheels each have a hydraulic rotaryshock absorber.The track is 12.33 m long, 580 mm wide and has 90 links; despite having four road wheels instead of five the ground contact area of the track is the same as the T-54 (3.84 m). Track center distance is 2.64 m[8]The vehicle has aground pressureof 0.63 kg/cm2.[3]
Other equipment
[edit]The ZSU-57-2's electrical power unit partially differs from the T-54, in that it consists of a more powerful G-74direct currentgeneratorwhich develops 3 kW (108 A at 27–29 V) at 2100 rpm and six 24 volt 6-STEN-140M or 6-MST-140 accumulatorbatteries(total battery capacity is 420 A-h), the batteries are used for starting the engine and an electrical power supply when the generator is shut down.[15]
The ZSU-57-2 is equipped with an automatic anti-aircraft sight of the plotter type with two collimators which can supervise a target with a speed of up to 350 m/s, a dive angle of between 0° and 90° and a slant range of up to 5,500 m; a simple mechanical sight is provided in case of failure. There is also an optical sight fordirect fireat ground targets.[15]
The 10RT-26E portable radiotransceiveris located on the right hand side of the turret interior. It has a range of 9-20 km(5-12 miles) when the vehicle is stationary, and from 7-15 km(4-9 miles) when the vehicle is on the move. It was later replaced by R-113 or R-113 radio transceivers. The TPU-4-47intercomsystem was later replaced by R-120 or R-124 intercom systems.[3][15]
Small arms for the crew members include twoAK-47assault rifles and a 26 mmsignalling pistol.[3]
Weaknesses
[edit]The main weakness of the ZSU-57-2 was the lack of asearchorfire-control radar;the vehicle was equipped with an opticalmechanical computing(analog)reflex sightas the solefire control system,so it could engage visible targets only. Night firing was also impractical. Also, the manual gunlaying and manual clip loading was not good enough, the rate of fire is not high enough, particularly considering that air-cooled barrels require quite long pauses for cooling at high rates of fire and the turret traverse is not fast enough to effectively intercept high-speed attack jet aircraft at low altitudes. The vehicle cannot perform aimed fire on the move.[8][15]
Although the ZSU-57-2 had the highest firepower among production SPAAGs of its time,[15]the anti-aircraft fire efficiency of a battery of four vehicles was even lower than that of a battery of six towed 57 mm S-60 anti-aircraft guns controlled by the PUAZO-6 anti-aircraft artillery director with the SON-9 fire control radar or later by the RPK-1Vazaradar.[8][15]It became obvious that the hit probability on a jet aircraft of the era was very low using only determination of target speed by aircraft type and determination of distance to the target by eye or by rangefinder; the ZSU-57-2 was designed to defend tank units againstNATOattack aircraft flying at subsonic speeds, but it entered service ten years too late. Aircraft technology had improved to the point that a SPAAG required a much higher rate of fire, turret traverse speeds of 50–100° per second and a fully automatic radar-controlled fire control system. Works No. 174 started a modernization programme for the ZSU-57-2 in parallel with the beginning of its serial production in 1957, but this programme was rejected due to the development of new radar-guided SPAAGs armed with small-bore autocannons and another tracked chassis.
The ZSU-57-2 still retained some of the features of its predecessor, the ZSU-37. One of them was the lack of an armoured roof on the turret. The advantages of an open turret for SPAAGs, such as very high elevation angle for AA autocannons, excellent visibility of the combat situation by the gunners and no need for induced ventilation of the fighting compartment during intense fire were significantly over-shadowed by the disadvantages. The open turret of the ZSU-57-2 made it vulnerable from above, and prevented operations underNBCconditions.[15]This flaw was partially nullified in the modifiedBosnian SerbZSU-57-2s, which had improvised overhead armour protection.
Nevertheless, its Western counterparts that were operationally available in the 1950s, such as the USM19 Multiple Gun Motor Carriage(based on theM24 Chaffeelight tank) and theM42 DusterSPAAGs (both armed with the famous40 mm Bofors M2A1 twin AA gun), had similar problems and were armed with less powerful weapons. The M42 Duster was tested with a T50 radar system in 1956 though it was a failure (production of the ZSU-57-2 had not started at this point).[15][18]
The Soviet Union would launch a program to replace the ZSU-57. TheZSU-37-2and-23-4were the products of the attempt, and the ZSU-23-4Shilkawould see widespread service in various countries.
Production history
[edit]Although the vehicle entered service in 1955 and in the same year the No. 174 Works located inOmskbegan producing the hulls and turrets, the first vehicles were completed in 1957[3]after the first 249 57 mm twin S-68 guns were produced by the Artillery Works No. 946 located inKrasnoyarsk.A total of 5,300 of these weapons were produced by the end of the 1950s.[16]The hulls and turrets were produced by No. 174 Works where the final assembly also took place while the Krasnoyarsk Works, belonging to the Ministry of Heavy Engineering, participated in some production stages. The ZSU-57-2 remained in production until 1960 when the No. 174 Works stopped producing the hulls and turrets for ZSU-57-2.[3][19]More than 2,023 ZSU-57-2swere produced in Soviet Union.[3][4]
250 ZSU-57-2 SPAAGs based on the ChineseType 59(a copy of the Soviet T-54A) tank chassis were produced under license inNorth Korea.The turrets were bought from the USSR and delivered between 1968 and 1977. Since the production of the ZSU-57-2 turrets ended in 1960 the turrets that North Korea bought must have come from decommissioned Soviet ZSU-57-2s.The turrets were ordered in 1967.[3][4]
Service history
[edit]Former USSR
[edit]The ZSU-57-2 officially entered service with the Soviet Army in 1955. The first vehicles began replacingBTR-40A's andBTR-152A's in the anti-aircraft batteries of tank regiments in 1957. It was first shown publicly during the military parade inMoscowon 7 November 1958.[3]
Initially, tank regiments had a singlebatteryequipped with four SPAAGs, later increased to two batteries, each equipped with four SPAAGs.[15]The vehicle was also used by somemotor rifle regiments(which in the 1960s had one battery equipped with four SPAAGs or, more likely, with six 23 mmZU-23towed twin AA guns). The anti-aircraft performance of the ZSU-57-2, however, was quickly found to be unsatisfactory and, because of rapid air force development, the vehicle was deemed obsolete by the early 1960s.[3]
ZSU-57-2s were gradually replaced by radar-guidedZSU-23-4 Shilkasfrom the beginning of 1965.[3]Towards the end of the 1960s, a frequent configuration was one battery of an AA battalion in a tank regiment equipped with ZSU-23-4s and another battery equipped with ZSU-57-2s. Unpopular in the Soviet Army, the ZSU-57-2 was completely replaced by ZSU-23-4s by the early 1970s.[15]
Most ZSU-57-2s were put into reserve storage while a few remained in service in tank training centres (as vehicles for driver training), until the end of the 1970s. Some were converted by army workshops into bulldozers. The last ZSU-57-2s were scrapped in the 1980s, while some dismantled vehicles were used as gunnery range targets.[3][dubious–discuss]One is preserved in theKubinka Tank Museum.[20][21]
Foreign service
[edit]ZSU-57-2s were exported like other Soviet equipment. Five otherWarsaw Pactmembers—Poland, East Germany, Hungary, Bulgaria and Romania—used it, as well as Cuba, Egypt, Iran, Iraq and Syria. North Vietnam and North Korea may have received theirs without payment.
East Germany
[edit]The first foreign operator of the ZSU-57-2 wasEast Germanyas it received its first vehicles in September 1957. From 1957 to 1961 theNational People's Armyreceived 129 vehicles,[4]eventually replacing them with ZSU-23-4s between 1967 and 1974. The ZSU-57-2 was completely gone from East German service by 1979. Some of the vehicles were converted into FAB 500U training vehicles for T-54 drivers and were passed on to the unified German state.[3]

Poland
[edit]Poland received its 129 ZSU-57-2s between 1957 and 1961.[4][22]They were also offered a production license for twin S-68 AA autocannons, but declined it.[3]Eventually, Poland replaced all its ZSU-57-2s with ZSU-23-4s. Seven Polish ZSU-57-2s are preserved, one at the Lubuskie Military Museum in Drzonów, one in Wicko Morskie, the largest anti-aircraft artillery firing range in Poland, one at the Land Forces Museum in Warsaw, one at the History and Tradition of Suvalkai Soldiers Museum inSuwalszczyzna,one inKoszalinand two at thePolish Army MuseuminWarsaw.[23]
Other Warsaw Pact countries
[edit]Three other Warsaw Pact members, Hungary, Bulgaria and Romania, received ZSU-57-2s once the ZSU-23-4 was introduced in the Soviet Army. Czechoslovakia imported one ZSU-57-2 for testing but it was rejected when it was realised that the domestically producedM53/59 Pragawas comparable to the ZSU-57-2.[3]
Former Yugoslavia
[edit]TheSocialist Federal Republic of Yugoslaviaordered 100 ZSU-57-2s in 1963. Deliveries were completed between 1963 and 1964.[24]They were passed on to the successor states during the 1992 breakup of the federal state. They were then used by the Federal Republic of Yugoslavia. There were 54 of those vehicles in service as of 1999, but this number decreased to 36 in the subsequent decade; they were withdrawn from active service by 2003.[citation needed]A number of ZSU-57-2 remained in Serbia national inventories until 2008.[25]: 183 Two vehicles captured by Croatian forces during theCroatian War of Independenceand were later also scrapped.[citation needed]
Slovenia
[edit]The air defence battery of the 44th "Wolves" armoured-mechanized battalion stationed in Pivka, belonging to the 4th Regional Command Postojna operated ZSU-57-2s.All vehicles were retired from service in late 90s.[26]

Finland imported 12 ZSU-57-2 SPAAGs between 1960 and 1961[27]alongside other kinds of Soviet equipment.[4]The ZSU-57-2swere designated 57 ItPsv SU 57-2, some of them remained in service to the end of the century. A ZSU-57-2M modernization programme was being developed in Finland which would equip the vehicle with radar and configurable ammunition. However, after the prototype was produced the project was abandoned because of high costs.[3]ItPsv SU-57swere withdrawn from service in 2006.[27]
People's Republic of China
[edit]The People's Republic of China was approached by Iraq in the early 1980s to develop a copy of the ZSU-57-2 system and a few examples were delivered to the PRC for reverse-engineering.[5][7]To meet Iraq's production order,NORINCOattempted to manufacture a copy with the improved amphibious chassis of theType 69-II tank. Several Type 80 SPAAGs were tested and accepted into service by the People's Liberation Army (PLA) in small numbers.[3]It was originally intended for the export market but didn't sell well. Greater success was achieved by Chinese-madeproximity fuseswhich could be used to modernize the S-60 and S-68 ammunition.[3][5][7]
Middle East
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/c/c0/ZSU-57-2-latrun-1.jpg/220px-ZSU-57-2-latrun-1.jpg)
Iraq ordered 100 ZSU-57-2sin 1970 from Soviet Union, which were delivered between 1971 and 1973.[4]TheNew Iraqi Armydoes not use these vehicles.
Iran ordered 100 ZSU-57-2sin 1966 from Soviet Union and they were delivered between 1967 and 1968.[4]Around 90 remained in service until 2002.[3]
Egypt ordered 100 ZSU-57-2sin 1960 from Soviet Union and they were delivered between 1961 and 1962.[4]ZSU-57-2s were not very successful during either theSix-Day Warin 1967 or theYom Kippur Warin 1973.[28]Despite that, the Egyptian Army operated 40 ZSU-57-2sas of 2003[29][30]and equipped them with radars. Egypt also bought Chinese-made proximity fuzes for its S-60 and S-68 ammunition.[3]
The Israelis captured a number of ZSU-57-2s from the Egyptians or Syrians. One resides at theYad La-Shiryonarmor museum inLatrun,West Bank,another at theIsrael Defense Forces History Museumin Tel Aviv, and the third (captured in 1973) at theIsraeli Air Force Museumin Hatzerim.
Cuba
[edit]Cuba received 25 ZSU-57-2s alongside other heavy equipment from Soviet forces stationed on the island in 1962 during theCuban Missile Crisis.[3][4]They remain in service.[3]
Combat use
[edit]While primarily an anti-aircraft weapon the ZSU-57-2 was also used in the role of ground support vehicle.

[edit]The ZSU-57-2 first saw major use in theVietnam Warby thePeople's Army of Vietnam(PAVN), in the beginning of theEaster Offensivein 1972. It also saw action during theHo Chi Minh Campaignin 1975. Several batteries of ZSU-57-2s were used for the air defence of the 201st and 202nd tank regiments during the Easter Offensive.[31]ZSU-57-2s were used by the PAVN against US aircraft, but it proved to be more effective against ground targets.[31]South Vietnam also used captured ZSU-57-2s.[citation needed]About 500 ZSU-57-2s survived the war. 200 are still in service.[citation needed]
Middle East
[edit]![](https://upload.wikimedia.org/wikipedia/commons/thumb/1/19/Damaged_Egyptian_ZSU-57-2_and_Other_Armour_During_the_Six_Day_War%2C_1967.jpg/220px-Damaged_Egyptian_ZSU-57-2_and_Other_Armour_During_the_Six_Day_War%2C_1967.jpg)
ZSU-57-2swere used during several conflicts in the Middle East including the Six-Day War in 1967 and the Yom Kippur War in 1973, in both cases by Egypt and Syria.[3]A battery of Egyptian ZSU-57-2stogether with T-34sdefendedEl-Arishairstrip. These were defeated by a company of IsraeliM48 PattonMBTs belonging to the7th Armored Brigadeduring an intense action on 6 June 1967.[28]ZSU-57-2s were not generally successful and a number fell into Israeli hands. In 1976, during itsintervention in Lebanon,Syria used ZSU-57-2sagainst theleftist militias.[32]During the1982 Lebanon War,they unsuccessfully engaged Israeli air force aircraft over theBeqaa Valley.However, the vehicles fared better when used against land targets.[3]
During theIran–Iraq War,ZSU-57-2s were used by both Iraq and Iran. Iraq also used ChineseType 80sduring this conflict and theFirst Persian Gulf War.Iraqi ZSU-57-2s, which could receive information from the radar onZSU-23-4sor9K31 Strela-1(SA-9 Gaskin)/9K35 Strela-10(SA-13 Gopher) surface-to-air missile systems were employed against IranianAH-1J SeaCobraattack helicopters.[citation needed]
When theSyrian Civil Warstarted, only 10 (out of 250) ZSU-57-2 were in active duty in the Syrian Army. During the war this vehicle was rarely seen and not documented in use. However, there is at least one piece of footage (which has since been removed by YouTube) showing that this vehicle was used by the Syrian Army in the Spring of 2014, in the fights at Harasta, Rif Dimashq Governorate.[33]The purpose of these vehicles probably has changed to ground support only.[34][35]
Yugoslavia
[edit]ZSU-57-2s saw service during theYugoslav Wars,usually in light batteries used by Serbs and Montenegrins of the JNA for attacking ground targets. They were used during thewar of independencewhen Croatian forces captured two ZSU-57-2s from theJNA.They were also used in the air defence role in 1999 during theNATO air raids against Yugoslaviawhen the Yugoslavs operated 54 of these vehicles.[3]

Variants
[edit]Former USSR
[edit]- ZSU-57-2prototype was based on a modified T-54 tank chassis equipped with experimental tracks. Unlike the production ZSU-57-2, the prototype weighted 26.172 tonnes, carried only 252 rounds: 172 rounds in clips inside the turret and 80 separate rounds in the nose part of the hull in a special ammunition stowage, had thinner armour (8–10 mm) and antennae mounted at the rear of the turret upper right side instead of in the middle.[1]The first vehicle was built in June 1950, the second in December 1950.[citation needed]
- ZSU-57-2improved prototype with an increased ammunition load of 300 rounds. Six were built between 1951 and 1953 for service tests.[1]
- ZSU-57-2– SPAAG mass-produced between 1957 and 1960.
- ZSU-57-2armed with modernised twin S-68A autocannon. Like the original ZSU-57-2, it officially entered service with the Soviet Army in 1955.[citation needed]
- ZSU-57-2converted into a bulldozer. After ZSU-57-2 SPAAGs were removed from AA units at the beginning of the 1970s, army workshops converted a number into bulldozers. The turret was replaced by a steel closed superstructure. The vehicle was equipped with the BTS-55 bulldozer blade.[36]
