While the fighter does have a basic IFF interrogator when the ILS is selected it turns off the IFF interrogator and that function is replaced with a Marker Beacon receiver function. Yes Marker Beacon (I know what your thinking). There is no GPS approach function or WAAS that we would consider standard. Plane uses Software function com/NAV radios and requires years and millions of dollars to change.
All tactical aircraft are on their own schedule of when, and potentially if, they will have ADSB Out. You would not believe the cost of getting FAA approval of a military solution to trying to be seen by others in aircraft that don?t want to be seen.
