Air Force guidance explains further that access to space requires the ability to launch critical space assets, when needed, by a mix of space launch systems from standard launch pads at major support facilities. This is to ensure that a launch failure or other catastrophic event does not prevent mission success. These critical space assets, or satellites, are used for a wide range of government activities such as communications, navigation, and ballistic missile warning. The Evolved Expendable Launch Vehicle (EELV) program, consisting of both Atlas V and Delta IV launch vehicles, was established as the strategic launch system to meet the nation's critical space mission needs and correspond with U.S. policy that requires U.S. government satellites to be launched on U.S. manufactured launch vehicles. Specifically, the EELV program's overarching objective called for the development of a national expendable launch capability for assured access to space that would reduce the overall recurring cost of launch by at least 25 percent to 50 percent while maintaining or improving the reliability and capability levels over those of the heritage systems. In its instruction on mission needs and operational requirements guidance and procedures, the Air Force states that key performance parameters are so significant that failure to meet their minimum values could be cause for program reevaluation or termination. The current EELV acquisition strategy addresses and reinforces the program's objective and system capabilities by encouraging contractor investment in launch vehicle development and promoting competition over the life of the program in an expected robust commercial marketplace. However, this commercial market never materialized. Furthermore, the availability of federal funding may affect future program strategy and condition. This letter responds to a request by the Subcommittee on Strategic Forces, Senate Committee on Armed Services. Our objective was to determine the extent to which the implementation of the Department of Defense's (DOD) EELV program has achieved assured access to space and projected program cost savings. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-04-778R/html/GAOREPORTS-GAO-04-778R.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-04-778R/pdf/GAOREPORTS-GAO-04-778R.pdf GAO-04-778R https://www.govinfo.gov/app/details/GAOREPORTS-GAO-04-778R Correspondence GAO-04-778R; Defense Space Activities: Continuation of Evolved Expendable Launch Vehicle Program's Progress to Date Subject to Some Uncertainity; Aerospace contracts Air Force procurement Federal funds National preparedness Performance measures Space exploration Cost analysis Strategic planning Rockets Commercial markets Air Force Evolved Expendable Launch Vehicle Program
