Renewed commitment to deploying missile defense would remove efficacy of Iran's nuclear weapons program
[ Page 15 ]
Using existing technology and continuing to improve existing systems, the United States could field a robust and credible defensive shield in the near term that secures the U.S. homeland and also protects deployed U.S. troops and allies. If the United States commits to focused investment, Washington can redirect time and resources that have been spent on yet unproven technologies. Expansion and improvement of the currently deployed Ground- based Midcourse Defense (GMD) system should be coupled with an expansion and evolu- tion of the current Standard Missile 3 (SM- 3) interceptors of the Aegis missile defense systems deployed on destroyers and ashore. Deployment of additional X-band radars to focus on tracking and discrimination functions, while leaving search and warning to the low- resolution radar systems, is also necessary to increase the reliability of both the Aegis and GMD systems. Add to that a recommitment to an updated Eu ro pe an Phased Adaptive Approach (EPAA) to BMD, and Iran’s ability to threaten U.S. interests with ballistic missiles would be severely curtailed (thereby reducing the effi cacy of developing a nuclear weapon).
