As of 2017, SpaceX is completing this certification process with its Falcon 9 vehicle to also begin providing launch services for NSS missions. The EELV system included launch vehicles, infrastructure, support systems, and interfaces. ULA stated it did not have any Atlas engines available to bid in order to submit a timely proposal.

Reducing the cost of launches and ensuring national access to space were the two main goals of the USAF space launch/EELV program. SpaceX bid the existing launch vehicles of Falcon 9 and Falcon Heavy, while Blue Origin was expected to bid New Glenn, ULA bid Vulcan Centaur, and NGIS's bid status was not reported. National Security Space Launch (NSSL) formerly Evolved Expendable Launch Vehicle (EELV) from 1994 to 2019 is a program of the United States Space Force (USSF) intended to assure access to space for United States Department of Defense and other United States government payloads.
