Today, Container ships move up to 20,000 containers at a time, but the travel time is around ten to fifteen days in the Atlantic and much longer in the Pacific. This would demand six hundred separate loads by airship, but it also would be mostly point to point with limited handling problems at either end. Better yet the actual trip time would be typically be one day. Thus we actually need fifty of these airships to do the job.
This also collapses infantry deployment times as well. A combat brigade can be thus deployed globally from its staging area and arrive on the battlefield inside of perhaps three days. Or from New Mexico to Beijing in about thirty six hours. Thus Sea lift may well have become obsolete.
