Aren't many of the F-16C/Ds actually younger than the C/D Hornets of the Navy? Including those of ANG units, I think some units received brand new C/Ds 5-10 years ago and not used ones from active units. I am sure the majority of them can be given life extension upgrades to keep on serving until the F-35 arrives. But yeah, the USAF needs to fully commit to the F-35 and/or to an interim solution and thus stop their hopeless campaign for buying more F-22s, as I said before and was highly criticized for. Ow yeah, and guys, get new tankers fast!
I wouldn't say the USN did better though! I think those additional Hornets will be formally (as in strength on paper) coming too late... The F-35C for the USN will be coming much later than the F-35A for the USAF...!
