given that theres no internal space for addons, retrofits, uprades, and the engine is already at the limits of performance then that's going to be on heck of a conjuring trick.
We don't know if the composite airframes will last that long, we can be very very certain the stealth technology used won't be relevant by then - and we can be very very certain that by 2070 any manned aircraft as slow, unprotected and unmanoeverable as an F-35 will have all the efficacy of a flying coffin
