[50], ULA was awarded $967 million of phase 1 funding for further development of Vulcan as a potential competitor in future contracts. Either a 4m or 5m fairing encapsulates the payload. In paying ULA for such fixed launch costs and executing the EELV program under a cost-plus contract, the DoD has reimbursed ULA for allowable, reasonable, and allocable costs for its launches, while requiring ULA to reimburse it on a per-launch basis for launches that ULA sells to its non-DoD customers.

[5][6], The NSSL program launches the nation's most valuable military satellites; contracts to launch lower value payloads, such as those of the Space Test Program, are awarded using different methodologies.[7]. [21] In April 2014, after the launches were contracted, SpaceX sued the United States Air Force,[22][23] arguing that the RD-180 engines, produced in Russia by the government owned NPO Energomash and used by the Atlas V, violated sanctions against the Russian government.
