s. 'ZSU' stands for Zenitnaya Samokhodnaya Ustanovka , meaning "anti-aircraft self-propelled mount", '57' stands for the bore of the armament in millimetres and '2' stands for the number of gun barrels. It was the first Soviet mass-produced tracked SPAAG. In the USSR it had the unofficial nickname "Sparka", meaning "pair", referring to the twin autocannon with which the vehicle is armed.

Origins

During World War II, ground-attack aircraft emerged as a significant threat to mechanized units on the move. Conventional towed anti-aircraft (AA) artillery was an inadequate response under such conditions due to the time needed for bringing anti-aircraft machine guns into action. This experience made it clear that an anti-aircraft tracked vehicle, armed with small-bore autocannons or heavy machine guns, was needed. Vehicles such as the German Wirbelwind

After World War II it became clear that the firepower of a single 37 mm AA gun was not effective against 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.

, began the development of a twin 57 mm S-68 automatic anti-aircraft gun based on the 57 mm S-60 in the spring of 1947. The first S-68 prototype (with ESP-76 electric drive), 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.

The final project of the ZSU-57-2 (Ob'yekt 500), armed with twin S-68s and based on a light-weight T-54 tank chassis, was finished in 1948. The first prototype ZSU-57-2 was built in June 1950, the second in December 1950. After official tests which took place between 27 January and 15 March 1951 in which the vehicle was driven for 1,500 km 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. The ZSU-57-2 officially entered service in the Soviet Army on 14 February 1955.

Overview

Based on past experiences with SPAAG designs, Soviet engineers designed a vehicle that used a modified T-54 chassis, 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.

Driver's compartment

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. The compartment is equipped with a single-piece hatch cover opening to the left and two periscopic vision devices. One of them can be replaced by the TVN-1 infrared vision device which is operated together with the infrared headlamp, 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.

Turret

The open-topped box-type welded turret has a ball-bearing race ring 1850 mm in diameter. The turret rear can be removed which makes replacement of the guns easier. The turret can be covered in the travelling position by a tarpaulin which has 16 plexiglass windows.

To aim the guns, base data such as the target's speed, direction and range must be entered into the sighting system by 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 the rangefinder. The upper front of the turret has two small ports with armoured covers meant for collimator

s of the sight.

To fire the guns, the breeches must first be opened. The left and right loaders, located in the forward part of the turret on both sides of the main armament, load clips into the magazines of 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 the gun and opens fire using an electric trigger, common to all barrels, or a pedal, which is individual for each barrel. If manual mechanical drive is used instead of electrohydraulic drive, 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, aims the gun in azimuth, the gunner aims the gun in elevation and the sight adjuster enters data into the sight. The loaders feed clips into the twin autocannon manually as needed.

Armament

The twin S-68s are recoil-operated and weigh 4,500 kg. Their construction was based on two 57 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. Each air-cooled gun barrel is 4.365 m long (76.6 bores) and is fitted with a muzzle 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 a direct current electric 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).

The guns are capable of firing up to 210–240 fragmentation and armour-piercing tracer rounds per minute, with a practical rate of fire of between 100 and 140 rounds per minute. Muzzle velocity is 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 11/7 nitro-cellulose powder, a projectile weighs 2.8 kg. Maximum horizontal range is 12 km (with an effective range against ground targets of up to 4 km / 2.5 miles. Maximum vertical range is 8.8 km with a maximum effective vertical range of 4.5 km / 14,750 ft). Fragmentation rounds have a safety-destructor which activates between 12 and 16 seconds after being fired so the maximum slant range of anti-aircraft fire is 6.5–7 km. 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).

The S-68 autocannon was the most powerful AA gun installed on SPAAGs at that time. 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 the Canberra

 type, an average of 1.7 hits were deemed necessary.

The vehicle carries 300 rounds, 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 a conveyor belt through a special port in the turret rear into an external metal wire basket on the back of the turret.

Armour protection

The ZSU-57-2's armour is welded rolled steel sufficient to protect the vehicle from 7.62 mm armour-piercing bullets at 250 meters.

Armour thickness is as follows:
  • Hull front: (upper) – 13.5 mm; (lower) – 15 mm; at 60 degrees upper
  • Hull sides: (upper) – 15 mm; (lower) – 13.5 mm
  • Hull rear: 8 – 10.6 mm at 45 degrees
  • Hull roof: 15 mm
  • Hull bottom: 13.5 mm
  • Turret sides: 13.5 mm
  • Gun mantlet: 15 mm
  • Turret roof: open

Maneuverability

The ZSU-57-2 has a maximum road speed of 50 kilometres per hour, which is reduced to around 30 km/h off-road. The vehicle has better acceleration compared with the T-54 because of its better power-to-weight ratio (18.6 hp per tonne). It has an operational range of 420 km on roads and 320 km across country. The vehicle can cross 0.8 m high vertical obstacles, 2.7 m wide trenches, ford 1.4 m deep water obstacles and climb 30° gradients.

The ZSU-57-2 uses the same engine as the T-54. It is a V-54 12-cylinder four-stroke V-shaped 38.88 litre water-cooled diesel which develops 520 hp (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.

The mechanical transmission in the rear part of the hull consists of a change gear quadrant, a multiplate main clutch of metallic contact, a manual gearbox with five forward gears, two multiplate planetary steering clutches with band brakes and two in-line final drive groups.

The chassis has four twin rubber-tyred road wheels with individual torsion bar suspension, a rear drive sprocket with detachable sprocket rings (lantern-wheel gear) and an idler wheel on each side. The first and last road wheels each have a hydraulic rotary shock 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 The vehicle has a ground pressure of 0,63 kg/cm².

Other equipment

The ZSU-57-2's electrical power unit partially differs from the T-54, in that it consists of a more powerful G-74 direct current generator which develops 3 kW (108 A at 27–29 V) at 2100 rpm and six 24 volt 6-STEN-140M or 6-MST-140 accumulator batteries (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.

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 for direct fire at ground targets.

Weaknesses

The main weakness of the ZSU-57-2 was the lack of a search or fire-control radar; the vehicle was equipped with an optical mechanical computing reflex sight as the sole fire 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.

Although the ZSU-57-2 had the highest firepower among production SPAAGs of its time, 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-1 Vaza radar. 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 against NATO attack 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 under NBC conditions. This flaw was partially nullified in modified Bosnian Serb ZSU-57-2s which had improvised overhead armour protection.

Nevertheless, its Western counterparts that were operationally available in the 1950s, such as the US M19 GMC (based on the M24 Chaffee

Former USSR

The ZSU-57-2 officially entered service with the Soviet Army in 1955. The first vehicles began replacing BTR-40As and BTR-152As in the anti-aircraft batteries of tank regiments in 1957. It was first shown publicly during the military parade in Moscow on 7 November 1958.

Initially, tank regiments had a single battery equipped with four SPAAGs, later increased to two batteries, each equipped with four SPAAGs. The vehicle was also used by some motor rifle regiments (which in the 1960s had one battery equipped with four SPAAGs or, more likely, with six 23 mm ZU-23

 towed 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.

ZSU-57-2s were gradually replaced by radar-guided ZSU-23-4 Shilkas at the beginning of 1965. 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 replaced by ZSU-23-4s by the early 1970s.

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.

Poland

Poland received its 129 ZSU-57-2s between 1957 and 1961. They were also offered a production license for twin S-68 AA autocannons, but declined it. Eventually, Poland replaced all its ZSU-57-2s with ZSU-23-4s.

Finland

Finland imported 12 ZSU-57-2 SPAAGs between 1960 and 1961 alongside other kinds of Soviet equipment. The ZSU-57-2s were 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. ItPsv SU-57s were withdrawn from service in 2006.

People's Republic of China

Several Type 80 SPAAGs were tested and accepted into service by the People's Liberation Army (PLA) in small numbers. It was originally intended for the export market but didn't sell well. Greater success was achieved by Chinese-made proximity fuses which could be used to modernize the S-60 and S-68 ammunition.

  • ZSU-57-2 prototype 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. The first vehicle was built in June 1950, the second in December 1950.
    • ZSU-57-2 improved prototype with an increased ammunition load of 300 rounds. Six were built between 1951 and 1953 for service tests.
      • ZSU-57-2 – SPAAG mass-produced between 1957 and 1960.
        • ZSU-57-2 armed with modernised twin S-68A autocannon. Like the original ZSU-57-2, it officially entered service with the Soviet Army in 1955.
        • ZSU-57-2 converted 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.
