The only thing USAF and USN fight over is appropriations. We have never had the best aircraft. The F-18 didn't fit USAF requirements but it more than filled the Navy's needs. The animosity you percieve just doesn't exist. There is no command structure in the world better than USJFCOM. To say that the Danes have a better working relationship is a mischaracterization.Big E.
Yes it was a good vintage!
I remember a suggestion of deciding which was the better fighter F-14 og F-15 - and the fact the F-18 is build on the one the Air Force wouldn't use.
There are recent examples; but what a wonderfull thing discipline is.
