All modern (2010s) '5th gen fighters' are fully networked; none have loyal wingman support yet (and LW aren't specifically tied to any generation, again) - even NGAD, if it is to fly tomorrow, will not have them - for a simple reason, they don't exist yet, and are arguably beyond what is doable at the current level of software.I defined 5.5 gen as fully networked capability with loyal wingman drone support. It is a capability that give definitive advantage against early 2000 F-22 Raptor. 5th platform is defined by stealth. J-16 with drones is not stealthy therefore not 5th gen platform. It is not 5.5th gen. It is very clear cut. Do not play stupid.
Unclear part is that you watch at a specific aircraft, when you are talking about a unit: when you say the word loyal wingman, it has consequences beyond commercial buzzword.
J-16 is not LO - but LWs operating with it may very well be LO. They may very well operate well forward of it, thus allowing it to reasonably hide behind escort and stand-in jamming(or simply fly low). The sum of such formation is quite likely to be LO, and may very well be functionally equal to a full stealth formation.
And, vise versa, 6th gen a/c may be in control of non-LO(or, more likely, lesser LO) elements. The aircraft itself will continue to be VLO, but the formation it operates with - will not.
It may even be stealthier and operate ahead of drone formation (which is actually the way USAF sees it, at least as far as we know).
