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. 0000009026 00000 n 0000001712 00000 n The approach continues procurement of launch services and launch capability from ULA for the next several years but provides for a full and open competitive environment for any alternative sources as soon as they are certified. ]p2c*lR-fHqmh"?

Shelby was a loyal supporter of ULA, and attempted to shoehorn in money to buy the RD-180 engines from Russia, against the wishes of Senator McCain and the rest of the Armed Services Committee.

In 2018, a competitive contract award to launch national security spacecraft was conducted between United Launch Alliance (ULA), Northrop Grumman Innovation Systems (NGIS), Blue Origin, and SpaceX. Boeing developed the Delta IV based around Common Booster Cores and the Delta Cryogenic Second Stage, while Lockheed Martin developed the Atlas V based around Common Core Boosters and the Centaur upper stage. The Medium & Medium-Plus vehicles use a single Common Booster Core (CBC), while the Heavy variant uses three CBCs.
