No aircraft which can fulfill the CCA type role is going to be "disposable". All the systems in that performance bracket are in the 20-40 million range minimum.
The most persistent thing misunderstanding about drones is people imagining that a supersonic capable stealth airframe is going to be really cheap just because it doesn't have a pilot.
Still, the F16 is 16 hours of maintenance per hour of flight or something close to that. Which probably isn’t terrible compared to other aircraft but doesn’t seem sensible for something without aircrew
I assume there are shortcuts like extending the service life of particular consumables and whatnot.
Even something like a Gripen, designed to be run from makeshift airfields needs 10 hours of maintenance per hour of flight. Maybe it’s just hard to build supersonic, combat capable airframes as was suggested above.
If these are airframes near the end of their natural lives it seems like a reasonable use for them, and safety margins matter less when nobody is on board. It’s certainly a better value proposition than using them as targets on the range.
