The Evolved Expendable Launch Vehicle (EELV) Secondary Payload Adapter (ESPA) Secondary Payload Planner's Guide is published by the Space Test Program (STP) Office, Space and Missiles System Center, Kirtland . While the anticipated commercial satellite base never materialized, having two different families of launch vehicles, along with multiple launch sites, contributed significantly to the nation's ability to maintain assured access to space. Vehicles are defined by the number of solids and the width of the payload fairing. The USAF began the EELV program in 1994, following many years of government-funded studies into improved systems and architecture.
