六、山姆大叔有利剑 美国早在50年代末就开始研究反卫星技术。60年代初开始部署两种地基核能反导系统。70年代中期,原苏联已有的供实战用的反卫星武器,使美国开始重视反卫星武器的研制,并把重点转向非核反卫星武器系统。由于当时原苏联的军用卫星数量多、寿命短、更换勤,大都运行在低地球轨道上,所以美国首先研制了由F-15飞机发射的反卫星导弹。 Sixth, Uncle Sam has a sword As early as the late 1950s, the United States began to study anti-satellite technology. In the early 1960s, two ground-based nuclear anti-missile systems were deployed. In the mid-1970s, the existing anti-satellite weapons available to the former Soviet Union enabled the United States to attach importance to the development of anti-satellite weapons and shift the focus to non-nuclear anti-satellite weapon systems. Since the Soviet Union at the time had a large number of military satellites, short life span, changing ground service and mostly operating in low Earth orbit, the United States first developed the anti-satellite missile launched by the F-15 aircraft.
