No, they’re not. There is no way to add stealth to their airframes and engines, and if you look at the list you’ll note that a lot of the F-16 kills have been via IR missiles. Bolting a new radar on and adding new weapons carriage capability is just like converting merchant ships to be carriers - it never really works out.

Also, two F-15’s have been lost to ground fire in US service.

We don’t need stealth within our borders.
