摘要: |
Ballistic and cruise missiles present a significant threat to US and Allied forces overseas, and to the United States and its territories. Missiles are attractive to many nations because they can be used effectively against an adversary with a formidable air defense system, where an attack with manned aircraft would be impractical or too costly. In addition, missiles can be used as a deterrent or an instrument of coercion. Missiles also have the advantage of fewer maintenance, training, and logistic requirements than manned aircraft. Even limited use of these weapons could have devastating consequences if armed with chemical, biological, or nuclear warheads. The ballistic and cruise missile threat continues to increase with the proliferation of missile technology. Over 20 countries have ballistic missile systems, and missiles likely will be a threat in future conflicts involving US forces. |
