二十年前,以色列驱逐舰艾拉特号被“冥河”反舰导弹一举击沉,此一事件对舰上面空防御提出了新的挑战。导弹比飞机更难于被发现,且能做快速而急剧的机动,故而对它的防御就需要一种快速反应的拦截系统。击毁一枚来袭导弹之所以不易,还因为它对破片杀伤弹头爆炸的经受能力比飞机要高得多。 Twenty years ago, the Israeli destroyer Elatt was sunk by the “Styx” anti-ship missiles. This incident posed new challenges to the air defense above the ship. Missiles are harder to find than airplanes and can make rapid and drastic maneuvers, so defenses need a quick response interceptor system. It was not easy to destroy one incoming missile, but also because it was much more capable of surviving a Kill than a plane.
