主战坦克的底盘往往几十年一成不变,而炮塔则不时地推陈出新,这主要是因为底盘一般不像炮塔那么容易过时。通常,只有当主战坦克换装重型附加装甲,导致动力装置和悬挂系统无法与车重相匹配时,才会考虑采用新的底盘。而这种情况在坦克的寿命周期内并不多见。相比之下,随着火炮和车辆电子技术的迅速发展,火炮、火控系统、光电设备、C~3I(无线电设备和战斗管理系统)和炮塔驱动装置会不断更新,最终导致炮塔旧貌换新颜。事实上,目前国外大多数主 The chassis of a main battle tank tends to be static for decades and the turrets evolve from time to time, mainly because the chassis is generally less obsolete than a turret. Normally, a new chassis will only be considered if the main battle tank is refitted with heavy-duty armor that will cause the powerplant and suspension system to not match the weight of the vehicle. This situation is rare in the life cycle of the tank. In contrast, artillery, fire control systems, optoelectronic equipment, C ~ 3I (radio equipment and battle management systems) and turret drives are continuously updated as artillery and vehicle electronics are rapidly evolving, eventually leading to turrets New color. In fact, most of the current foreign master
