And that is what the US Army's Project Walrus is about – putting together an entire action unit of war machinery, with all the wiring and plumbing preinstalled, and placing it in the most strategic place. Whilst this would completely rewrite the way that war is conducted, the Walrus - a massive lozenge-shaped blimp the size of a football field capable of transporting 500 tons at a time - could offer solutions to myriad peacetime problems, opening land-locked countries to trade, enabling heavy construction materials to be delivered into urban centres with minimum disruption, freeing our highways of high volume, heavy loads, offering a more robust and agile air transportation network capable of absorbing disruptions due to weather or attack. Indeed, business logistics could again be completely rethought and streamlined because many physical transportation limits would no longer apply once a fleet of commercial walruses became available. The walrus does not require an airstrip and can land on water or on open ground.
