Functional Cost-Estimating Relationships for Spacecraft.
Abstract
The costs to acquire space-based missile defense systems are often reviewed by DoD. Issues are raised concerning the cost models used to generate cost estimates for space-based missile defense systems. The Ballistic Missile Defense Organization questions the use of traditional weight-based spacecraft cost models developed by the Air Force Space and Missile Systems Center. The concern is motivated by changes in satellite designs of future systems where smaller but more capable spacecraft are being built. Using weight-based cost models yields lower cost estimates, although the spacecraft are more capable. IDA developed spacecraft functional (engineering and manufacturing) cost-estimating relationships (CERs) at the spacecraft subsystem level using performance and physical characteristics that are not primarily weight-based. We developed nonrecurring (design, development, and test) and recurring (production) CERs for the spacecraft bus, including ground support equipment, and for communications payloads. The CERs show that programmatic aspects, which reflect the requirements and acquisition environments that the satellites were acquired under, have considerable influence on satellite costs.
