This paper proposes a method to find efficient system of systems configurations regarding drone range requirements and base locations to operate from. Using an heuristic optimizer, sensitivity analyses are presented for inspection flights of the German Railway system of Deutsche Bahn as well as the US natural gas pipeline system. It is concluded that longer drone ranges facilitate either more efficient mission designs or alternatively enable fewer bases of operations and thus less capital expenditure while limiting mission efficiency through increased average target approach distances.
