## Highlights

In September 2009, the President announced a revised approach for ballistic missile defense (BMD) in Europe. The European Phased Adaptive Approach (EPAA) is designed to defend against existing and near-term ballistic missile threats and build up defenses over four phases as threats mature and new BMD technologies become available. Although the approach will include capabilities such as radars and landand sea-based BMD assets, the Department of Defense (DOD) has not yet established EPAA life-cycle costs. EPAA is DOD's first implementation of its new, regional approach to BMD. GAO was asked to evaluate DOD's plans for implementing EPAA. GAO reviewed the extent to which: (1) DOD has developed guidance and addressed management of cost and schedule for EPAA, and (2) DOD planning for EPAA is informed by operational performance data. GAO reviewed key legislation, policy and guidance, and initial plans for implementation and asset allocation.
