Alright, so I think I've done enough discussion on the idea of unmanned tanker in other threads to continue here.

What I think they need is something that's very stealthy, not overly expensive, can take off and land from EMAL catapult and deliver more fuel than your usual J-15B buddy to buddy refueling. Having J-15 doing all the refueling requires a lot more take off and landing, which takes a toll on its airframe.

What this brings is just greater operational flexibility to support J-36, H-20, naval air wing and CCAs operating far away from China's airspace. Even if you can control the air space 3000 km out, it takes a long time for a YY-20 to get out there. It's more relevant if you have a carrier near by, that it can launch several of these tanker drones that can refuel forward operating aircraft.

USN is developing MQ-25 Stingray for this purpose.

Self-explanatory.

Me again with a request for help: Altogether at Zhuhai 2024 there were 6 Y/YY-20A seen, but after now weeks of search, I was only able to find one construction number confirmed :( ... can anyone help to find the missing ones!

Y-20A: 11059, 20048 (cn. 0031), 20243 & 20249
YY-20A: 20248 (maybe cn. 1039), 20249

... especially the "maybe" cn. 1039 would help to solve the question on the number of tanker altogether.

A glimpse of the WS-20s.

I expect them to have clappered fan blades like the ones on the PW2000 and CFM56-5X, probably 32 blades. They might move to wide chord ones later from what I've heard.
Current fan blades (32x clappered):

Future (24x wide chord):

Zhuhai air show 2022, they have shown composite wide chord 22 fan blades of WS-20 series.

Zhuhai air show 2024, they have shown titanium 32 clappered fan blades.

so the point is, there is no problem to go with wide chord composite fan blades from the beginning. so let see

For the WS-20s on the Y-20Bs they might not opt for composites.
