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.
The Air Force budget would grow to $234 billion while Space Force spending would shrink to $26 billion under the White House's yearly ask.
