Commercial GaN can be used for power banks. This is not proof that they are used for radars in 2015.

There are several GaN technologies. Not just GaN on SiC. There is GaN on Si, there is GaN on Sapphire, etc.
The main advantage of using SiC as a substrate is that it handles higher temperatures better while still being relatively cheap to manufacture.

IMO it seems that these new nozzles are much improved similar to J-35's nozzle, they look like the F-35 nozzle with angular petal surfaces for better stealth compared to the original WS-10C's flat petals.
BTW do we have any idea what exactly is improved with WS-10C2 or is it just a nozzle change
They are same technology, the only difference is that GaN is more efficient wide-bandgap semiconductor material than GaA, it would be relatively easy to change one for the other.
Not always the case, Chinese military has more mature engines compared with its civilian counterparts. For all we know the military might have been the ones to drive down the production prices of GaN so that it became competitive in the civilian market.
I don't have any proof, but I don't think China would have started production of J-20 without the latest and capable technology they can get their hands on.
I mean sure it's true but there's literally no reason not to other than price.
Power, cooling, will have to be considered, as well as software.
But we are getting lost in the weeds -- you previously wrote in post #3221 that "No, J-20 always had GaN-on-SiC radar not just J-20AS/A!" and the way you wrote it was very confident.
Myself and others have explained why the use of materials in the civilian sector at a given time period does not automatically equate to production ready capability on a military aircraft in the same time period.
You also have not demonstrated any credible rumours (such as from PRC side credible individuals) or evidence to support your confident statement.
I hope you can appreciate that your statement was overreach.
For things like electronics, it is generally the case that the military gets older, more proven technology than civilian equivalents. If one looks at the processors used on F-35s for example, they are literally from the 2000s.
For engines, it's more variable, but in the PRC case it is as much because the engines they have available are insufficiently capable for civilian use (among other things, in terms of fuel efficiency) rather than maturity or development cycles per se.

Oh my God I cannot get over how good the electric (?) blue tint looks on those EO windows.
Never understood why there is no dedicated EW variant of the J-20. The side weapons bays are ideal to house the sensing/emitting equipment needed, with the space for the main bays to be used for cooling, processors and perhaps a bit more fuel and to leave enough room for 2x PL-15/16 for self defence.
The same could be said of the Raptor.
