Would PLAAF even be interested in a stealthy flanker?
Rumours say PLANAF chose J-20 for their new carrier 5th gen fighter, so J-31 lost a big potential customer. PLAAF could have had a role for J-31 as their own F-35, but maybe they're looking at the USAF procurement model and thinking it's not for them?
So will a J-11D (or C -- are they the same aircraft, or are SAC going to try and pump out another two flanker derivatives??) be used to supplement the J-20? I.e.: J-20 will be the PLAAF's A team for their heavy weight, long range air superiority fighter with J-11C/D as a plane with similar range but less stealth (thus avoiding the USAF debacle where they will soon lack a large number of heavy weight fighters once F-15s start retiring).
Is there any muttering as to whether this is a PLAAF sponsored project, or if it is another lone wolf SAC endeavour.
