The lowest layer (a kinetic kill weapon located near a potential target) could destroy bombers, cruise missiles or warheads. The higher layers (in orbit) are aimed at the ICBM's themselves and the warheads. Later additions to SDI could include more advanced sensors and weapons to track and kill cruise missiles & bombers at long range. This could also include a pop-up weapon (launched during an attack) that uses x-ray lasers against sub-launched missiles, which are otherwise very difficuly to catch since their flight time is so short.
