摘要

GBI (Ground Based Interceptor) is the missile element of the Ground-based Mid-course Defense (GMD) portion of National Missile Defense (NMD). It initially comprises a Raytheon exo-atmospheric kill vehicle (EKV) launched aboard an Orbital Sciences boost vehicle (BV), but later may consist of a Lockheed Martin BV-Plus booster armed with either an EKV or a Miniature Kill Vehicle (MKV).
