A couple of new reveals/rumors regarding the JH-XX project, although I do not know how credible these are. They were posted by "苏明的真理信念".
Summary: (correct if inaccurate)
- SAC is suffering from a shortage of manpower due to the pre-research team taking back-to-back vacations during the holiday season.
- The bomber's designation is H-17 (allegedly as per official reports).
- The bomber represents a "stealthy platypus" - possibly a reference to a stealthy Su-34-style design. Another but lesser possibility would be an enlarged YF-23-style design.
- Project is currently in the pre-research phase, but the general layout has been completed and simulations completed.
- Engine configuration would be either twin WS-15/10 or quadruple WS-19.
- The final go-ahead for full-scale development has not been received yet.
The OP also made a few comments regarding other topics:
- The fate of the improved versions of the J-11, J-15, and J-16 remain uncertain.
- The biggest project at SAC right now could be the 5th-generation carrier-based fighter.
- The PLAAF's follow-on 5th generation fighter will also be from CAC.
- SAC's fighters apparently cost less than 1/2 of CAC's fighters.
Take these points with a healthy dose of salt, but as usual wait & see.
