ULAs use of these tactics artificially created a need for relief from legislative restrictions on its ability to continue using RD-180relief that, with the DoDs active assistance, ULAs actively sought in the fiscal year 2016 omnibus appropriations bill. The Governments objectives were to develop Payload Category A, B, and C launch system prototypes, through shared investment with industry partners that will lead to EELV certified launch systems capable of providing launch services for all EELV-class National Security Space (NSS) missions. As of 2019, these launch vehicles were the primary methods for launching U.S. military satellites, along with the Falcon 9 developed by SpaceX.

EELV was important not only to reducing the launch costs of the Department of Defense, but also to the continued world-wide competitiveness of the US commercial launch industry. [3][4], On 1 March 2019, the program name was changed from EELV to National Security Space Launch (NSSL) to better reflect the growing commercial launch market and the changing nature of launch contracts, including the potential for reusable launch vehicles. xkqW@F%N(ISI>bUqE-9?

The payload interface at each port has been standardized, allowing for hosted and separable payload inter-changeability, late payload integration, APL requirements are not addressed in the SIS but their >> The Delta IV Medium, Medium-Plus and Heavy configurations are evolved from flight proven Delta II and Delta III systems while incorporating the latest technology into a family of vehicles maximizing the use of common hardware. Program cost savings are achieved through operability improvements such as the use of common components and infrastructure, a standard payload interface, standardized launch pads and reduced on-pad processing; and acquisition improvements such as launch vehicle block buys. [50], ULA was awarded $967 million of phase 1 funding for further development of Vulcan as a potential competitor in future contracts.

The EELV program was initiated in 1994 and planned to be a "rolling-downselect" of launch vehicle providers from four to one. After many years of government-funded studies on the subject of modernized launch vehicle systems, the Air Force finally developed a "roadmap" in 1994 for the acquisition of Evolved Expendable Launch Vehicles (EELVs) to replace the DELTA IIs, ATLAS IIs, and TITAN IVs then in use at Cape Canaveral.
