“That’s the problem with war procurement — war is unpredictable. War is wasteful. And more than anything, war is expensive. It was expensive when mass-producing propeller-driven aircraft and diesel-powered tanks, and it’s even more expensive when you’re fielding stealth strike fighters whose pilots have to worry about the potential cyber-vulnerabilities of their new network-enabled weapons. Paying for it all with borrowed money makes everything even more expensive.”
Philip Ewing from DoD Buzz explains why, despite some suggesting it, the Air Force doesn’t ask Apple for an iFighter.
