Delta IV Payload Planners Guide - October 1999 One of the Air Forces long-term goals for the EELV program is to have at least two certified launch providers able to compete for the full range of national security launches. As of September 2019, it has two manifested classified national security flights for the USAF in 2021.[43][44][45]. As of 2015 the EELV program was actively pursuing a competitive scenario for launch acquisitions, but the launch industry is currently undergoing numerous changes, and the makeup of the industry in the future is uncertain.

The ESPAStar platform leverages the available mass margin from any EELV launch to provide an affordable path to space for payloads. [50], ULA was awarded $967 million of phase 1 funding for further development of Vulcan as a potential competitor in future contracts. [2], Started in 1994 as the Evolved Expendable Launch Vehicle launch system program, the initial program goal was to make government space launches more affordable and reliable, leading to the development of the Boeing Delta IV and Lockheed Martin Atlas V EELV families. Standard payload interfaces were touted as another way to save money and improve efficiency, though success in that area remained to be seen. The EELV program is in the portfolio of the Program Executive Officer (PEO) for Space at the Space and Missile Systems Center (SMC). - A final check of specifications will be conducted prior to launch. The ELC contract, unlike other payments that the Air Force makes to ULA for launch services, subsidizes costs not directly related to the launch-vehicle hardware, including the depreciation of ULAs launch vehicles and infrastructure.
