54 • Perform mission support services of program management, systems engineering, and mission assurance The following is a list of all WBS Elements supporting this phase, including how they compare to both design reference systems. Note that WBS Elements map to either the components of this phase or to the specifications which serve as inputs to the components. Table 13. Summary of all WBS Elements in the Dispose ConOps Phase The above WBS elements were used to derive cost estimates for ADR vehicle manufacturing, management, operations, and ground systems costs, as well as associated launches. Estimating costs for ADR Vehicle Manufacturing: Aerospace assessed an approach to ADR with ADR transfer vehicles acting as space tugs to move modules from GEO to a graveyard orbit. ADR transfer vehicles are based on Northrop Grumman’s Mission Extension Vehicle (MEV). They are assumed to deliver modules to a graveyard orbit at the end of their design life (every 10 years), or twice during the mission lifecycle, and again at the 30-year mark for end of mission disposal. Aerospace did not consider launch costs for ADR transfer vehicles in the ADR methodology. For cost estimates, Aerospace considers mass estimates using the MEV in addition to in-house costing methodologies. For our cost estimates, we leverage the same first-unit cost assessed by Aerospace ($500M/unit) and also apply the same 90% learning rate to account for improvement over time with experience in production. We determine the number of transfer vehicles needed based on the updated inspace mass using the scaling factor, the ADR transfer vehicle payload capacity, and duration of ADR operations.
