以往,防空系统的主要作用是用于发现和摧毁进攻的飞机,但如今,由于对地攻击武器如“灵巧”炸弹、巡航导弹、遥控飞行器、反辐射导弹及反坦克武装直升机技术的日臻成熟,使防空形势变得更为复杂。要有效地保护行进中的主战坦克、步兵战车和自行火炮系统免受空中威胁的打击,就必须具备全天候对各种空中威胁做出快速反应的能力。 In the past, the main role of air defense systems was to find and destroy offensive aircraft. But nowadays, due to the maturing of ground attack weapons such as “smart” bombs, cruise missiles, remotely piloted vehicles, anti-radiation missiles and anti-tank helicopter gunships, Make the air defense situation more complicated. To effectively protect the moving main battle tanks, infantry fighting vehicles and self-propelled artillery systems from the threat of air threats, they must have the ability to respond promptly to various air threats around the clock.
