Lla ZSU-57-2 (ZSU-57-2) (Ob’yekt 500) est un canon antiaériens automoteur soviétique (SPAAG), armé de deux canons automatiques de 57 mm. ‘ZSU (en)’ signifie Zenitnaya Samokhodnaya Ustanovka, ce qui signifie « monture automotrice antiaérène », ’57’ représente l’alésage de l’armement en millimètres et ‘2’ représente le nombre de barils de canon. Origines: Pendant la Seconde Guerre mondiale, les avions d’attaque au sol sont apparus comme une menace importante pour les unités mécanisées en mouvement. L’artillerie antiaérienne remorquée conventionnelle (AA) était une réponse inadéquate dans de telles conditions en raison du temps nécessaire pour mettre en action des mitrailleuses antiaériens. Cette expérience a clairement indiqué qu’un véhicule à suivi antiaériens, armé de canons automatiques à petit alésage ou de mitrailleuses lourdes, était nécessaire. Des véhicules comme le Wirbelwind allemand avaient été utilisés à bon effet dans les batailles finales de la Seconde Guerre mondiale.

The Accidental Tank Destroyer

Lla ZSU-57-2 (ZSU-57-2) (Zenitnaya Samokhodnaya Ustanovka) was intended to be the Soviet Union’s premier shield against jet aircraft. Entering service in 1955, it featured twin 57mm autocannons mounted on a lightened T-54 chassis. However, it was a « daylight only » weapon with no radar and a slow manual sighting system, making it nearly useless against fast modern jets. While it failed its primary mission, crews quickly discovered its true calling: ground support. Its massive high-velocity shells could shred light bunkers, APCs, and even the side armor of Main Battle Tanks, earning it the nickname « Sparka » (Twin-mount) and a fearsome reputation in urban combat.

Design Engineering: Thin Skin, Big Teeth

  • The Lightened T-54 Chassis: To save weight for the massive turret, engineers removed one road wheel (reducing it from five to four) and thinned the armor down significantly. While a T-54 could take a hit, the ZSU-57-2 can be damaged by heavy machine gun fire.
  • The S-68 Autocannon: These guns are modified versions of the towed S-60. They fire a massive 2.8 kg shell with a muzzle velocity of 1,000 m/s. This gives them incredible kinetic energy, allowing the Armor-Piercing (APC-T) rounds to penetrate over 100mm of armor at close range. [Image diagram of the twin S-68 recoil and loading mechanism]
  • Open-Topped Vulnerability: The turret is massive and open to the sky. While this provides the crew with excellent visibility for tracking planes and prevents toxic fumes from building up, it makes the vehicle extremely vulnerable to airburst shells, grenades, and even rain.
  • Manual Fire Control: Unlike the later radar-guided « Shilka, » the ZSU-57-2 relies on an optical-mechanical computing sight. A dedicated crew member has to manually input the targets estimated speed and range—a near-impossible task against supersonic jets.

Operational History: A Global Menace

  • Vietnam Service: North Vietnamese forces used the ZSU-57-2 during the 1972 Easter Offensive. While it struggled to hit U.S. Phantoms, it was devastatingly effective at clearing South Vietnamese defensive lines and bunkers.
  • Middle East Wars: In the hands of Syrian and Egyptian forces during the Six-Day War and Yom Kippur War, it was often used as an improvised « assault gun. » Israeli tankers learned to prioritize these vehicles because their twin 57mm guns could disable a tanks tracks or optics in seconds.
  • The Yugoslav Wars: During the 1990s, Serbian and Croatian forces used the ZSU-57-2 almost exclusively for ground support. Its ability to elevate its guns nearly vertically made it the perfect tool for clearing snipers out of high-rise buildings.
  • Modern Obsolescence: By the 1970s, the Soviet Army replaced it with the 23mm ZSU-23-4 Shilka, which traded the 57mm’s « punch » for radar-guided accuracy and a much higher rate of fire.
