History

In the late 1940s, the Soviets started to develop a 57 mm anti-aircraft gun, to replace its 37 mm guns. Three different models were presented, and the winning design was made by V. G. Grabin. According to western intelligence sources, the German prototype gun 5,5 cm Gerät 58 formed the basis for the design. The Soviets were also able to study German 5 cm Flak 41 guns that had been captured following the Battle of Stalingrad
Battle of Stalingrad

The prototype passed the field tests in 1946 and was accepted into service in 1950, after some minor modifications. The anti-aircraft gun was given the name 57 mm AZP S-60. Grabin continued the development and fielded the SPAAG version ZSU-57-2
ZSU-57-2
The ZSU-57-2 is a Soviet self-propelled anti-aircraft gun , armed with two 57 mm autocannons. '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....

 in 1955.

The fire direction device was developed from the German Lambda calculator (Kommandogerät 40, 40A, and 40B) and was called PUAZO-5A. It had also a distance measuring device called D-49. The fire direction was also made more effective by including Grom-2 (10 cm wavelength) radars to the AA-batteries. The whole system was called SON-9. Later on, the calculators would be changed into the more modern RPK-1 Vaza, which had been designed by M. M. Kositskin. The calculator and the radars were transported by Ural 375 trucks.

The 57 mm gun replaced the 37 mm divisional guns in Soviet service in the 1950s. A divisional anti-aircraft regiment consisted of two AA-batteries with six 57 mm guns each. The PVO air-defence troops AA-regiments consisted of four 57 mm AA-batteries (24 guns).

In the mid-1960s, the Soviet divisional anti-aircraft units began replacing their AA-guns with missiles, and by the end of the 1970s, the AA-guns had almost disappeared. However, they were used in many other countries.

Operational history

The S-60 and its Chinese copy (the Type 59) have seen combat in several wars all over the World, e.g. the Six-Day War

 and Iraq War), the S-60, normally deployed in battalions of 36 guns, served consistently in defense of divisional headquarters and field artillery assets.

Ammunition types

The S-60 fires ammunition in 57x384SR caliber, a cartridge noticeably weaker than the 57mm ammunition of either Bofors 57mm AA gun, or Soviet 57 anti-tank guns of World War II. Modern anti-aircraft rounds have not been developed for the gun - the main characteristics of the Soviet-era ammunition is listed in the table below. In addition to these People's Republic of China manufactures ammunition in 57x384SR caliber, designated Type 59 HE-T, Type 59 AP-T, and Type 76 HE-T.
