The present invention is a method of interception. When a missile is launched and detected by a satellite, an anti-missile rocket is launched to intercept it. When the anti-missile rocket nears the point of interception, it goes into a turn of about 180 degrees, to reverse its course, and comes in behind the enemy missile, at a speed almost equal to that of the ICBM. In this maneuver, coming in behind the ICBM, it reduces the relative speed of the two rockets from about 13,000 mph to about 50 mph, and allows the interceptor missile to approach the ICBM at a slow speed and easily destroy it.
