The GMD program provides a ground-based midcourse interceptor for protection of the United States against ICBM threats. The National Missile Defense (NMD) program was established on April 1, 1997, and Boeing was chosen as the lead system integrator (LSI). Supplementing the Boeing effort on the booster, subcontractors include Raytheon for the exoatmospheric kill vehicle (EKV) and the sea-based X-band radar (SBX); TRW and Northrup Grumman for command and control, battle management, and communications (C2BMC); and the U.S. Army Corps of Engineers for construction. Currently, the program is in Phase B (product development), operating with an initial deployed capability. Key
