Operational flexibility of a launch system can be increased with a common interface between a launch vehicle and the family of compatible satellites. This improvement in flexibility, which enhances launch responsiveness, is achieved via the ability to rapidly replace or exchange a satellite (or select a different launch vehicle) during the launch preparation process.
This study focused on concepts for interface commonality with a selection of Air Force launch vehicles and payloads. Currently, among the launch vehicles examined, there is limited interface commonality. Historical interfaces and attempts at commonality were reviewed to determine constraining factors. Concepts for providing interface commonality in both the near and far term are recommended for further study. However, implementation and maintenance of common interfaces will require increased launch vehicle performance, adequate performance margins and a cultural change which permits control of interfaces and payload weight limits
