The U.S. has tested using missiles to shoot down ballistic warheads fired by a hostile country. Here's a look at how the system would work.

Personal note: How was this system tested by computer or was there an actual test to ensure the defensive measures would intercept the incoming warhead? Not mentioned.
Just curious and how soon does the warning indictor come on focusing on the incoming projectile? (Not mentioned).
