Having first been revealed in model form, China's newest fighter has taken to the air for the first time. Unlike the previous J-20, this fighter is in the medium weight class and it's model form suggests it's meant for export, at least in this stage of development.
It may enter service as a complement to the J-20 in a Hi-Lo combination and/or as a naval fighter aboard carrier aircraft.
Various designations have included F-60, J-21 and J-31. Confirmed data specs have not yet been revealed, although it's design seems to blend several design aspects previously seen in the F-22 and F-35 programs from the Unites States.
