The SU-76 (''Samokhodnaya Ustanovka 76'') was a Soviet self-propelled gun used during and after World War II. The SU-76 was based on a lengthened and widened version of the T-70 light tank chassis. Its simple construction made it the second most produced Soviet armoured vehicle of World War II, after the T-34 tank. Crews liked the vehicle for its simplicity, reliability, and ease of use. However, the steering was also sometimes regarded as cumbersome, leading crews to also refer to the vehicle as ''suka'' ("bitch") or ''Suchka'' ("little bitch"). It was also nicknamed ''Golozhopiy Ferdinand'' ("bare-arsed Ferdinand") due to its very light armor and somewhat similar silhouette, when compared to the Germans' heavy ''Ferdinand/Elefant'' casemate tank destroyer of some 65 tonnes in weight. == History == Design of the SU-76 began in November 1942, when the State Defense Committee ordered the construction of infantry support self-propelled guns armed with the ZiS-3 76.2 mm anti-tank gun and the M-30 122 mm howitzer. The T-70 chassis was chosen for mounting the ZiS-3 gun, and was lengthened, adding one road wheel per side, to facilitate better gun mounting. The vehicle was completely enclosed by armour. The power-plant setup installed in the first mass-produced SU-76s was unreliable. Two GAZ-202 automobile engines were used mounted in "parallel", each engine driving one track. It was found to be difficult for the driver to control the two engines simultaneously, and strong vibration forces led to early failures of engines and transmission units. After 320 SU-76s had been made, mass production was halted in order to resolve the problems. Two chief designers at the GAZ plant, N. A. Astrov and A. A. Lipgart, changed the power-plant arrangement to that of the T-70 - the two engines were mounted in tandem on the right hand side of the vehicle. The armoured roof over the gun compartment was removed to improve access to and servicing of the weapon. This modified version, called the SU-76M, was placed in mass production in early 1943. During the halt of production, a replacement vehicle was produced which mounted the 76.2mm gun on captured German tank chassis. This vehicle was called the SU76i. After production resumed, GAZ and two factories in Kirov and Mytishchi produced 13,932 SU-76Ms; the larger part of the order, over 9,000 vehicles, were built solely by GAZ. Mass production of the SU-76M ceased in the second half of 1945. In contemporary accounts SU-76Ms are often referred to in texts, public radio and TV broadcasting as SU-76s with the "M" omitted, due to their ubiquity in comparison with the original SU-76s. The SU-76 was the basis for the first Soviet tracked armoured anti-aircraft vehicle, the ZSU-37. Mass production of the ZSU-37 was continued after SU-76M production ceased. The SU-76M was withdrawn from Soviet Army service after the Second World War ended. 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「SU-76」の詳細全文を読む スポンサード リンク
