To what extent do you think the PLA will tell Chengdu to share it's sensors/avionics/codes to Shenyang, knowing J-20's technological maturity? I'm just very interested if there is cross-transfer of technology across the platforms. To me, Shenyang's FC-31 project isn't as well funded as Chengdu's J-20, so I don't know how the living hell they can develop so many of these sensors/avionics from scratch. Esp. when Chengdu did a lot of the heavy lifting...

CAC and SAC are subsidiaries of AVIC, they share a lot...

the tail part of J-20 was designed by SAC, so I would imagine the same from the CAC, in fact, it was rumored CAC helped out on the J-16 control codes

in terms of sense, avionics, and etc. China has public bidding platform for all military-related development and equipments, so it mainly depends on the budgets and needs

There are all sorts of subsystems they could use. Not just from the J-20. If weight is an issue they can also use systems from the much lighter JF-17/FC-1 and work on those.

I don’t thing subsystems weight will be an issue. Generally miniaturization of systems works towards the favor of newer designs. The J-20’s size is primarily driven by range and internal carriage requirements.

AESA radar is usually built in modules. So you can make a smaller radar with less of the same kind of modules.
It will have less power and degraded detection range if it uses less modules but it will fit.

Typically a medium weight fighter developed by the same country has to weigh 2/3 of that of the heavy weight fighter to justify the expense. Maybe we can extrapolate some of J-20's numbers from those of the FC-31, which are publicized at air shows.

do we think NRIET will make this J-35 radar or will it be a LETRI/607 project?
