IDA investigated the Future Combat Systems' (FCS) Key Performance Parameters (KPPs) and their underlying Critical Technologies (CT's) to identify metrics to support Department-level monitoring of the FCS program and to gain an understanding of the implications of the KPPs (and their underlying CT's) upon the FCS program. This work focuses on the KPPs for Transportability and Sustainability/Reliability. The investigation into metrics for transportability revealed that the C130 Transportability requirement for FCS vehicles is a constraint that leads to a less survivable platform but without improving Unit of Action (UA) transportability. Further, even the transport of individual vehicles is improved only under the most favorable conditions. The FCS Sustainability/Reliability KPP aimed at improving reliability by the use of prognostics to increase operational availability. We show that the reduction of administrative logistic delay time complements the improvement of reliability and that the use of prognostics may help more with administrative logistic delay time than with reliability. Finally, we examine water generation (a CT) from fuel exhaust and show how it may affect UA sustainability.
