Latest anti-missile technology

At present, only warships, is that the Aegis missile intercept enemy missiles or km short-haul/medium-haul 650-3100. (No land development.) Ideally, the United States has 16 Aegis-equipped ships deployed in the Pacific Ocean, at all times, but recent budget cuts means that the time is not the case.
Warnings: Although Aegis has done well in some tests, no appeal organized by a missile that can be called decoys. Bulletin of the Atomic Scientists warns that a successful experiment without objection, should not be treated as an effective system as is the case in the real world.
