Question - What is the current level of China's operational capabilities for its combat aircrafts as unmanned platforms?
To put the theme of discussion into persepctive:
Now, China operates around 600 J-10s and around 400 J-11s, of which large portions of them (mainly the A, B variants for the J-10 and A, B, BS, BH variants for the J-11) will most likely retreat from frontline services in the coming 10-20 years. Instead, J-10 and J-11s of older variants will be relegated to homefront, rear-guard and/or supporting duties and roles until their retirement.
Say, would it be feasible and viable for all of these 4th-gen fighters of older variants to be converted into unmanned fighters that can either be strictly loyal wingmans that will be controlled by J-16s and J-20s, or capable of semi/fully-autonomous mission-execution capabilities? If so, how fast and until when before we can this realistically achieved?
While the retrofitting of older fighters certainly will not cost a measly amount, but doing so can grant immediate availability of UCAVs on platforms that are already capable of active combat roles during periods of tension and/or wartime - While simultaneously waiting for the serial production of newer, built-from-scratch UCAVs to begin/ramp up.
There is also the factor of pilot resource management - Instead of having a not-exactly small pool of fighter pilots keep flying older, less capable fighters (and thus increasing the risk of losing this precious manpower from enemy action due to their less-capable fighters), the newly-freed up fighter pilots made available from the conversion of those older fighters can then be redirected towards piloting newer, more capable Gen-4.5 (J-16), Gen-5 (J-20, J-35/31) and even Gen-6 fighters. This certainly helps to lift the combat performance and prowess of the PLAAF and PLANAF across the board - Though not just increasing the size of the combat aircraft fleet, but also focusing precious manpower onto more-capable platforms while letting robots taking over less-capable platforms.
Though, I believe that the assigned roles for these converted unmanned fighters should depend on the variant, capability and duration of which these older fighters have served prior to their conversion.
The general ideas would be for:
1. Not-so-old and/or comparably-capable airframes to be relegated as autonomous fighters that are capable of semi-/fully-independent mission-execution, patrolling hostile airspaces and providing ISTAR to allied units, plus capable of engaging and dogfight against enemy aircrafts on its own volition; while
2. Older and/or less-capable airframes to be relegated as bomb trucks and/or missile trucks that would conduct attacks against enemy ground targets and/or launch missiles against enemy aircrafts from longer distances away, either as loyal wingmans or with some level of autonomous capabilities.
