This volume describes the environmental consequences of system level Testing of the MX weapon system at Vandenberg Air Force Base, CA (VAFB) including ground tests and flight tests of the MX missile from an operational basing mode. Alternative missiles other than MX as described in Volume I are being considered for possible inclusion in the FSED and, therefore, flight testing at Vandenberg. The only significant variations in environmental impact to the Vandenberg area expected as a function of the alternative missiles being considered are related to the handling and launch safety considerations of a specific missile. The standard launch safety analysis and procedures currently in force for all missile assembly and launch tasks at Vandenberg will be adhered to for any missile selected for Full-Scale Engineering Development (FSED) and Flight Test at Vandenberg.
