Naval forces are able, without resorting to diplomatic channels, to establish offshore anywhere in the world, air fields completely equipped with machine shops, ammunition dumps, tank farms, warehouses, together with quarters and all types of accommodations for personnel. Such task forces are virtually as complete as any air base ever established. They constitute the only air bases that can be made available near enemy territory without assault and conquest; and furthermore, they are mobile offensive bases, that can be employed with the unique attributes of secrecy and surprise — which attributes contribute equally to their defensive as well as offensive effectiveness.
