Re: Scrap a development because...
Good point - The issue with the 'loyal wingman' drone concept is that it seems a good idea at first but in practice, less so. First if you're talking accompanying 6th gen fighters then they need to be as stealthy as the mother-craft or it gives away the manned ship. There's an issue with autonomy and who is responsible for compliance (and legal responsibility) with the rules of engagement (pilot? s/w manufacturer? integrator? etc) - China is probably less bothered about this than Western forces.
If you're looking at ISTAR, why not just use a drone optimised for that? If you want to get red forces to light up their tracking maybe that's a use. As a decoy, its useless as its bloody expensive with with limited evasion abilities and SAM's usually have more than one missile ready. If you look at how the F35 should work, loiter with stealth detecting away and then launching BLOS missiles its not clear how the loyal wingman fits in...
