Shenyang FC-31 / J-31 Fighter Demonstrator

Which in a way... I think it make sense that China chooses the 601 (J-31) design over the 611. J-31 had a couple (two I think) of prototypes flying already... while the 611 design might still be on drawing board, so in term of speed of development, the J-31 do have some advantages.

Although it can be argued that J-20 is already up there for some time now (although still in prototype stage) but to downsize a J-20, is not going to be easy, and it is going to take some time, also what engine will be used to power the downsized J-20? We know that the Chinese will use WS-15 for J-20, but will the same engine be used for the downsized J-20? Or a new engine needed to be developed, or the Chinese needed to fall back onto the Russian to supply engines? If a new engine was to be developed, then more time is needed.

For J-31, I believe it already had a powerplant - WS-13.

(Personal note: I like the look of J-31 better... look more... beautiful than the J-20, please don't bash me for that)

Where did that information come from?

Navalized is more of the word than downsized, I think. After all, J-20 isn't any bigger than J-15, why does it have to be downsized?

Well... that is the rumour ain't it. A smaller J-20. And also even if there it isn't downsized, the newly navalized J-20 had not been seen yet, not even a sized model.

Actually the rumours were talking just about a navalised J-20, nothing about it being downsized as far as I can tell.

There were rumours of a downsized J-20 before that, but it was not for naval use but for land use I think.

Given the aerodynamic characteristic of the J-20, I don't it can take off at lower speed than J-15 even with the help of canards. So, if J-20 style aircraft want to get onto the Liaoning, it needs to be re-desgined. Make it lighter, changing the main wings, lower its taking off speed, more powerful engines, etc...

I'll buy that, except I'm afraid theres only 1 prototype?? but it is a looker, and far more practical as a carrier aircraft than any vaporware J-20, looks like the PLAN is sold on Shenyang, they have done a fantastic job on the J-15. brat

The aerodynamics of J-20 would actually make the aircraft better for carrier operations than J-15. The same principles that make J-20 so maneuverable would let the J-20 to fly at a lower speed or have better control.
