The Defense Science Board Task Force on Science and Technology Issues of Early Intercept EI Ballistic Missile Defense Feasibility was convened in December 2009 and concluded its deliberations in May 2011. The Terms of Reference TOR for the Task Force focused on defense against regional-level adversary ballistic missiles. It directed the Task Force to consider both technology issues and architectural constructs to accomplish Early Intercept defined in the TOR as that interval in a ballistic missile s flight between thrust termination and final deployment of warheads andor countermeasures. The complete terms of Reference are in Appendix A, and the Task Force membership is in Appendix B. A list of briefings to the Task Force is in Appendix C. In February 2010, the Department of Defense issued a key document that comprehensively outlined the objective of the Nation s ballistic missile defense program Ballistic Missile Defense Review Report, February 2010. This document clearly spelled out the top priority role of regional ballistic missile defense wherein the U.S. committed itself to defend not only our military assets overseas, but also to provide missile defense assistance to our allies and partners. The U.S. has many allies and partners worldwide, so there is a wide range in the difficulty of achieving defensive coverage of their territories. The collection of allies in Europe represents the largest land mass to cover, and the Task Force devoted much of its analytics to this European theater. However, in examining the issues related to EI in the context of the Phased Adaptive Approach PAA in Europe EPAA, the Task Force additionally considered a different kind of EI from that spelled out in the TOR, namely the issues related to using regional forward-based defenses to get an early shot at intercontinental ballistic missiles ICBMs heading to the U.S.
