In summary, while the previous two-contract structure met DOD's needs for unprecedented mission success and an at-the-ready launch capability, the scope of its cost-reimbursement contract limited DOD's ability to identify the cost of an individual launch, as, according to DOD, direct launch costs were not separated from other costs. For example, DOD paid for hardware through a firm-fixed-price contract (ELS), but funded infrastructure and engineering support through a cost-plus-incentive-fee contract (ELC). The ELC cost-reimbursement contract was not transparent according to DOD officials, who had limited understanding of the activities funded under this contract.
