以往获取空中优势要依赖于空空作战,压制敌方战斗机,使之不能对己方攻击机进行拦截。但近年来这种局势发生了很大变化。面空武器成为获取空中优势的最大障碍。敌方空防压制(SEAD)一般是指通过毁坏或瓦解手段来压制、摧毁敌方地面空防系统或暂时降低它们的能力。两种最常用的手段是用电子干扰飞机在防区外对空防雷达实施干扰或用反辐射导弹对雷达进行攻击 In the past, acquiring air superiority depended on air and sea operations, suppressing enemy fighters and preventing them from intercepting one’s own attack aircraft. However, this situation has changed dramatically in recent years. Face-to-face weapons have become the biggest obstacle to gaining air superiority. Enemy air defense (SEAD) generally refers to the ability to suppress, destroy or temporarily reduce enemy ground air defense systems by means of destruction or disintegration. The two most common means are the use of electronic jamming of aircraft to intercept air defense radars outside the zone or the use of anti-radiation missiles to attack radars
