57 mm AZP S-60 ((ロシア語:Автоматическая зенитная пушка С-60), abbrev. АЗП (AZP); literally: ''Automatic anti-aircraft gun S-60'') is a Soviet towed, road-transportable, short- to medium-range, single-barrel anti-aircraft gun from the 1950s. The gun was extensively used in Warsaw Pact, Middle Eastern and South-East Asian countries. ==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. 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 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. The performance of AAA in Vietnam against low-flying aircraft led the Soviets to bring back many guns from storage to supplement the Surface-to-Air Missiles, whose performance at low altitude was less than satisfactory. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「AZP S-60」の詳細全文を読む スポンサード リンク
