Well almost everyone has agreed that the Chinese has been working on a 4th generation prototype since about 2001-2002. However, its number of projects and designations that quite murky. Some give actual numbers like J-12, J-13, while others use other designations such as Super-10, J-xx, or simply next-gen fighter project. For example, some have speculated that the Chinese are working on a Super-10, while others have claimed that there will be a brand new fighter based on the J-10. Some sources claim that there are two different next-gen projects, whiles others claim there is three. Also, what projects are supposedly being worked on by Shenyang and what projects are supposedly being worked on by Chengdu vary by source.
well there should be more than two models that the Chinese is workin on,and its reasonable that there are more than one institution involved in this. it is such so that if you screw up on one,you dont have to start all over again. in the end they are just gonna take all the successful models and dump the ones they dont like,like the yf-23
Can Chinese govt afford that, do chinese govt pay for the development cost of both companies ?
the two two J-10 currently being shown in Zhuhai airshow,probably belong to early variant,notice the old "Tri-odd" IFF antenna located in tail.
I watched how the J-10 flew over Zhuhai, in 30 degree Celsius temperatures and high humidity.
The pilot did none of the show tricks like post-stall or tail slide or pitch-back, but turns were very tight, initial rate of turn very high. It was clear there is a lot of potential in this airplane to achieve the same maneuvers more quickly.
The pilot rarely used afterburner and the degrees of canard deflection were small. Still, the airplane flew very well. I reckon it will beat F-16C or MiG-29/SMT easily.
