N-a-B...
I'm not that optimistic. Follow the trajectory of the JSF news since they started. It's already gone through "it's late and it will cost more" and "it's later than that and will cost even more": the Cloggies have come down from 85 jets to 37, and who knows when or how far the UK will get beyond 48 aircraft to the 138 now planned.
The USAF is trying to throw the A-10 force into the crusher to alleviate huge pressures on maintenance people (because of "don't ask ALIS"), which are already crimping F-16 readiness. Aesa upgrade of the F-16s has already been binned, which will leave them very susceptible to EW in the 2020s. (Amraam engagements? GLWT.)
Fortunately our adversaries have sat on their hands instead of perceiving a vulnerability and developing sensors aimed dead-center at F-35 stealth levels. Wait, what?
