The CBO does say that by adding another 21 C-17s to the currently planned 180-aircraft fleet, the Air Force could deliver an additional 1,400 tons within the first six days—the point at which a prepositioned ship might arrive. And, the additional C-17s would continue to increase deliveries to a war theater by some 350 tons per day during surge operations. However, CBO sees the airfield infrastructure needs of C-17s as potentially problematic, whereas it says an airship would need no infrastructure. Hmmmmm.
Reports of production troubles on the SpaceX rocket that could contend for military cargo deliveries happened to coincide with a different company’s concept receiving an early nod—one that might not require a rocket at all.
