[16] Each company has a 50% stake in ULA. 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. 0000015754 00000 n 1. The contractor was standardizing payload interfaces, launch pads, and infrastructure so that all configurations of each contractor's EELV family can be launched from the same pad and payloads can be interchanged between vehicles in the same class (i.e., medium, intermediate, or heavy). [38] This launcher features a reusable first stage and fairings, which lowers the cost per mission. 0000001979 00000 n [36] As of 10November2022[update], 19 launches remain. The Atlas V family uses a Russian RD-180 to power the first stage Common Core Booster. This website is best viewed in browsers such as: Edge, Firefox, Chrome, or Safari.
