FlyPony,
And for whatever its worth, the F-15E (and its many derivatives) retains all the air superiority capabilities of the F-15C/D. USAF has 224 F-15Es in service which they'll keep flying at least as long the upgraded C/Ds and likely longer.
Unless I am badly mistaken, I thought the F-35 was designed to
replace F-15s and F-16s, no matter the updates and virtually all other aging USAF aircraft including the A-10s according to Lockheed Martin and the US DoD. All of this, at a cost yet to be determined, but fully expected to exceed $1 trillion when all is said and done. Now, due to technical difficulties, it seems the F-35s requires previously unforeseen protection support, most likely when leaving the air combat scene when "stealth" doesn't matter as much as when entering. So with less than 200 F-22s available, do you really think the F-15s and F-16 will be around still in 2045, e.g., 30 years from now to escort the F-35 safely home? After all, the USAF desires and will probably get over 1,400 F-35s. IMHO, the F-35s are supposed to be around far longer than any of the aircraft you mentioned, but one never knows for sure, the way the F-35 program continues to unfold.
