Very poorly written article.....
A significant portion of the Air Force Fixed Wing fleet are cargo and are not as sophisticated or subject to the stresses of combat aircraft so the days in maintenance comparison is meaningless.
The AF and USN spent $3.3 billion on process, so why is the AF tossed into a conversation about the Navy, true both have aircraft but other than that, totally different environments.
What impact does the stupid just in time supply chain have on maintaining 50 year old aircraft? Parts are only manufactured after they are paid for, huge delays because all parts must have FAA certification before use.... a process loaded with delays....
