The nature of orbital mechanics is such that only one site is needed to be able to reach any satellite in low Earth orbit. An ASAT site located in the western United States or Pacific Ocean area will be under the command of CINC SPACE, who will launch only on order of the National Command Authority. The KE ASAT will be launched when the target comes within reach (generally within an hour), then the KKV will separate from the rocket booster and make course corrections enabling it to strike the satellite and disable it, after which the KKV will re-enter the atmosphere and burn up.
