西方未来地空武器系统的发展方向还不清楚。不过,现在看来用美国的爱国者系统来代替现有的近程和中程导弹系统显然是太贵了。毫无疑问,现有的地空武器将落后于未来威胁的发展,到本世纪末就会没用了。至于低空威胁,由于现有的设备比较先进,还会再延用一段时间。然而到1995年或2000年就必须更新了。到目前为止,新武器系统的多国发展计划一个接一个地失败,这就促 The direction of future development of the Western air and space weapons system is still unclear. However, it appears that it is obviously too expensive to replace the existing short-range and medium-range missile systems with the U.S. patriot system. There is no doubt that the existing air and ground weapons will lag behind the development of future threats and will be useless by the end of this century.

So far, the multi-national development plan of the new weapons system has failed one after another, which prompted
