|Online information on militaryphotos.net and other Chinese military sites are circulating part of the photos allegedly be part of stealth mod of JH-7A bomber, which is currently speculated as JH-7B.
Previous revelation shows that there is such a version may be in development. JH-7A, however, is not known with internal bomb bays.
Thus, it is speculative that WS-13 or RD-93 may have been used in the new bomber, and the extensive modification in the fuselage may contain small internal bomb bay.
More will come soon, as expected.
