[14] The USAF moved 7 launches from Delta IV to Atlas V.[15] To end litigation and competition for a limited market, both companies agreed to form the United Launch Alliance (ULA) joint venture. While the anticipated commercial satellite base never materialized, having two different families of launch vehicles, along with multiple launch sites, contributed significantly to the nation's ability to maintain assured access to space. [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.

[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. This would be difficult to achieve since projections showed that the EELV would not be able to meet the requirements of as much as 42 percent of the estimated commercial market. xkqW@F%N(ISI>bUqE-9?
