The abstract notes, "The purpose of this report is to summarize the results of three companion studies designed to investigate both the performance growth potential of the Saturn V and the utilization of Saturn V equipment to fill the performance gap in the intermediate payload range between the Saturn IB and the Saturn V. This report includes significant data which is intended to aid the planning of future missions. This data reflects some of the various vehicle configurations which can be used by mission planners to satisfy payload desires in excess of the Saturn IB and Saturn V."
