目前美国和苏联在空间总共部署了大约200颗军用卫星,其中美国75-80颗,苏联约125颗。这些军事卫星技术先进,用途广泛。有的用于侦察地面设施、部队实力或搜索各类无线电波,有的用于监视核爆炸和导弹发射活动,还有的用于绘制地球表面图形。不久前美国“阿特兰蒂斯”号航天飞机施放的价值5亿美元的“长曲棍球”卫星是一颗监视卫星,载有高性能雷达,能透过云层观测地面发生的重大情况,也可为隐形轰炸机提供地面攻击目标,或搜寻远
Currently, the United States and the Soviet Union deploy a total of about 200 military satellites in space, of which 75-80 are in the United States and 125 are in the Soviet Union. These military satellites are advanced and widely used. Some are used to detect ground facilities, force strength or search for various types of radio waves, some for monitoring nuclear explosions and missile launches, and others for mapping the surface of the Earth. Not long ago, the $ 500 million lacrosse satellite put on space shuttle Atlantis in the United States is a surveillance satellite carrying high-performance radars that can see the ground through the clouds, Provide ground-attack targets for stealth bomber or search far
