The Atlas V family uses a Russian RD-180 to power the first stage Common Core Booster. At the same time, another 14 boosters were to be procured competitively beginning in 2015, with the initial launches to be performed in 2017. One of the Air Forces long-term goals for the EELV program is to have at least two certified launch providers able to compete for the full range of national security launches. endobj By 2016 the Air Force was working to introduce competition into the Evolved Expendable Launch Vehicle (EELV) program.

[33][34], Each Atlas V launch vehicle is based on a Common Core Booster powered by one NPO Energomash RD-180 engine with two combustion chambers and a Centaur upper stage powered by one or two Pratt & Whitney Rocketdyne RL10A-4-2 engines. 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. The EELV program's Delta IV and Atlas V launch vehicles are produced by United Launch Alliance (a joint venture of Boeing and Lockheed Martin formed in 2006).
