If bases can no longer reliably sustain fleets; if maritime denial can persist after the defending fleet has been destroyed; and if sensing and striking power no longer have to be concentrated aboard fleets of warships, then the problem extends beyond the vulnerability of any particular carrier, airfield, or naval base. It is whether the carrier strike group remains the most efficient and survivable architecture for concentrating maritime combat power when concentration of platforms is no longer required to concentrate effects. It is whether the secure forward logistical base can continue performing the strategic function that made it central to maritime power projection: concentrating the resources necessary to overcome geographic distance and sustain combat power near an adversary.
