Its not only the IR jammers but they seem to have revived the original design. They had to abandone the original design and make compromises because of weight. The WZ-9 engines was to weak to take on the weight. Now that they have revived that old original design means that they have been able to solve the engine problems.
....
But are we sure that these are new-build aircraft ??
IMO it simply does not make any sense to have the original configuration, that was too heavy due to a limited engine output ... then to redesign the fuselage in parts, the tail + gear as well as the canopy ... build several (and we speak of really many) of these weight-reduced serial standard airframes and now suddenly with reportedly a new engine - and here I'm even more skeptical than the often mentioned WZ-16 is not ready yet - all the weight reductions were left and the old heavy airframe used again.
IMO it would simply make much more sense to retain the standard airframe and simply add the new engine !
As such I'm now almost sure that they are in fact not a new build Z-10A, H or K version but simply a few refurbished prototypes and pre-serials modified to be assigned to an operational unit.
Just my 2 Cents.
