L'interception pendant la phase de descente exigera que l'intercepteur des missiles soit situé à proximité des cibles des ICBM, surtout, on peut le supposer, des concentrations de villes américaines.
Some weapons will be able to intercept ICBMs in the early ascent, and some in the final descent, as well as those designed against the mid-course phase of their intercontinental trajectories (0920) Interception in the early ascent phase will require interceptors to be located quite close to the launching sites of the ICBMs, possibly on ships or aircraft and far from North America.
